Still Life

*

This ist our neu "Still Life" test target. We"re combiningsome of the facets from vault shots (DaveBox and Res Chart) intothis und the "Multi Target" shooting below, plus added a numberof elements that are an extremely revealing of various camera characteristicsand foibles.

Du schaust: Olympus e-pl5 test

Here"s what zu look for in this target:

Tone-on-tone einzelheiten & noise suppression:The fabric swatches bei the pinwheel were chosen due to the fact that they show a lotof tone-on-tone detail, throughout a wide range of colors. This zu sein justthe kind of einzelheiten that noise suppression handling tends kommen sie flattenout. If you look at the detail bei these swatches as ns ISO increases,you"ll see nur where various cameras start to lose subtle detail.-- the white and tan swatches and the dark swatches tend kommen sie be particularlyrevealing des this. Die label des the vinegar bottle (second from theright) ist another an excellent place kommen sie look zum lost detail from noise suppression,as the bild of the person at the top des the label zu sein actually a depictionof a mosaic. The dark colors in the elevator and in the figure"s clothescontain detail that"s really quickly lost wie man a camera"s noise suppressionsystem kicks in. Cameras through really high-quality, low-noise sensorsthat require little noise suppression will be able kommen sie hold ~ above thedetail an these areas, numerous others will show only a uniform swath ofsmudged color.Another ar where you"ll quickly see the effects of over-aggressivenoise suppression is bei the white salt grains of the salt grinder inlower left. Cameras room often more conservative about suppressing noisein highlight locations (because our eyes often tend to see less des it there),but many cameras it seems to be ~ to schutz a hard time hold onto ns subtle shadingsthat distinguish die salt seed from every other, particularly hinweisen higherISO levels.Fine Detail: You"ll uncover a lot of well detailin the label of the beer bottle on die right, in its good cursive text,but die other bottle labels organize a gewächs of fine einzelheiten as well. Finetext is often a an excellent visual indicator von resolution, due to the fact that our brainshave in excellent idea von what the buchstabe should look like, soare very quick zu notice even minor loss von detail.For really fine detail, look at to ns circular scale/calculator top top theright side von the scene. Some von the well lines there are extremelyfine indeed. Looking hinweisen results from numerous different cameras with thistarget, we discovered that camera noise-suppression system often confusethe well lines with image noise, and so flatten lock out. There"s alsoa quite range of fine buchstabe sizes an this chart as well, when again greatvisual cues zum resolution and detail.Highlight Detail: three elements an this sceneshow turn off (or nur up) a camera"s ability zu hold onto to mark detail.As discussed above, die salt seed (and reflections von the studio lights)in ns salt mill space examples von fairly ethereal highlight einzelheiten thatcameras" anti-noise processing periodically obliterate. Ns folded whitecloth under die mug on die right side of the frame an in similar way shows alot des white-on-white einzelheiten that zu sein easy to lose, particularly if acamera"s ton curve zu sein too contrasty. Together it transforms out though, die mostsensitive test of a camera"s highlight abilities seems to be the hankof white embroidery thread in the upper appropriate corner. These fibers areunusually bright and reflective, deswegen its easy zum a camera zu blow outdetail an them.Shadow Detail: numerous elements von this subjectare useful zum evaluating zero detail, particularly the schwarze farbe mugand die pieces von folded schwarze farbe velvet, both under und inside the mug.The bottoms of the beere bottles so provide part gradations of deepshadow, und the clump des peppers in the bottom of the pepper oil bottlehad a fair little of detail that"s far down at ns shadow end of die tonecurve.We were actually surprised when we created this scene nur how darkthe velvet und sides of the beere bottles ended hoch being. Also with thebright studio lights shining straight on it, ns velvet bei particularstays way, way down at ns shadow ende of ns tone curve. With most camerasand on most monitors, ns velvet wollen simply appear as bei unrelievedswatch of black. To lakers whether it has deep detail or not, in mostcases you"ll schutz to open the record in bei image editor und boost thebrightness dramatically, zu bring the einzelheiten up right into a visible range.Preservation des "Shape" in Strong Colors:As freundin approach the extremes of a camera"s shade gamut (its range ofrecordable colors), it i do not care more und more difficult zum the camerato zeigen fine gradations des tone, because one or more of the RGB colorchannels space close kommen sie saturation. It"s notfall uncommon to lakers a brightlycolored piece of clothing or a vivid flower appear in digicam photosas just a blob of color, because ns camera ran nach oben against the limitsof its color gamut. Die brightly colored embroidery threads bei the upperright portion of the ausblüten Life target are great examples of situationswhere this could happen. Pay specific attention to ns bright redand dark blue color here, together these space both color near the edge ofthe typical sRGB color gamut.Color accuracy and white balance: It"s prettysmall an there, however we"ve contained a mini-MacBeth chart, i beg your pardon displaysvery closely controlled shade swatches. Our Multi Target (see below)sports a full-sized MacBeth chart, but ns one right here serves as a goodcheck von color balance und rendition, and is also useful weil das checkingwhite balance top top this particular shot. Image noise and detail vs ISO: As pointed out above,this target includes many facets useful for evaluating detail lossto anti-noise processing. We"ll therefore always shoot a full set oftest bild of this target across each camera"s ISO range, for everycamera us test. (See below.)

Multi Target

*

Our neu "Multi Target" was erste put into use bei April, 2009, replacing the earlier "interim" design. This target incorporates a number of elements that integrate aspects des the previous Multi target, as well as ns previous Viewfinder Accuracy or "VFA" chart. Here"s some of what you"ll find in this target:

Framing marks: This chart advanced from die earlier Viewfinder Accuracy chart, dafür one des its major uses ist to measure viewfinder accuracy. (See notes in the Viewfinder Accuracy section, at die bottom von this page, zum more die info on this.)

USAF resolution targets: bei important use von this target is in evaluating lens quality, looking just how well sharpness holds trost as you move from die center to die corners of the frame. The little "USAF" resolution targets arranged at ns center, in the corners, and along the diagonals are really useful zum making fine judgements about blur, flare and aberrations bei the image. We generally show crops von a USAF chip from a corner of the target and from ns center, to zeigen how lenses host sharpness punkt wide und telephoto focal distance lengths.

Alignment "bullseyes:" We discover these graphic from ns graphic arts world (used zu align sheets von film in the alt film-based prepress days) really useful zum seeing chromatic aberration bei lenses. Die bold black/white facets are good zum seeing die colored edge caused von CA in the corners des the frame.

MacBeth ColorChecker Chart: This is about as usual a color standard together you kann sein get this days, very widely available for only mildly exorbitant cost, and quite fine controlled an its production. It thus serves together a good basis of comparison bolzen cameras and between test setups. Imatest so understands die MacBeth colors really well, and uses them kommen sie produce its shade accuracy map that us feature in all our reviews.

MacBeth ColorChecker SG Chart: die ColorChecker SG chart gives a wider range of colors, zu give a much more detailed map von a camera"s color handling. We haven"t started using this chart in the color-accuracy graphs we frequently offer, yet expect to do so at part point in the future. An the meantime, we sometimes refer kommen sie this graph internally, to get a more complete idea von what a camera"s color map aussehen like.

Log C/F Target: the progressive resolution pattern located just below ns center of the target ist a log in C/F (logarithmic comparison vs spatial frequency) chart. Digital camera noise reduction routines work über looking hinweisen levels des local contrast, flattening-out detail at progressively lower spatial frequencies as the local comparison decreases. (This zu sein very commonly seen an human hair, grass, foliage, and other subjects with subtly-contrasting good detail.) This chart lets Imatest analyze nur how a camera makes ns tradeoff between contrast, detail, and image noise.

Color Starbursts: The sechs circular starburst elements arranged around the target room intended zu reveal de-mosaicing artifacts und color-dependent resolution issues. The six starbursts carry out examples von each combination of RGB colour intersecting each other. (That is, red, green, und blue against black, to add red against green, green against blue, and blue versus red.) offered that the most usual sensor RGB color filter sample (the so-called Bayer) pattern has actually twice as numerous green pixels as red or blue, you"ll generally lakers that the green/black starburst shows the best resolution, while die blue/red one shows ns worst. Die effects of different sensor geometries and color filter variety patterns will be revealed here.

Musicians Image: Synthetic test patterns only tell you deswegen much. When we oase a lot of pictorial images bei our other test targets, we assumed it would certainly be useful to include a klein "natural" bild here as well.

Resolution Target

*

Part von the impetus in developing the neu Multi Target in April 2009 was zu switch to using a neu 2x target for the resolution measurements, since the original ISO 12233 chart we"d offered since ns site zuerst began in 1998(!) had become inadequate zum testing the highest-resolution cameras. We"d weil das quite some time had actually a "homemade" 2x target, use a shrunk version von the ISO 12233 chart, shot at 1/2 size. The resolution number on that chart all needed zu be doubled kommen sie convert to the actual values, though, deswegen we decided zu go with a advertisement 2x target to eliminate possible confusion on the part des our readers. Number on this neu 2x resolution chart jetzt read directly in hundreds des lines/picture height. (Because virtually all of the area von this neu resolution chart zu sein now meaningful for resolution measurements, there was no longer space on it to overlay ns MacBeth und other color targets on our prior Multi chart; hence die simultaneous change in our Multi target.)

"Sunlit" Portrait:(This zu sein our "Outdoor" Portrait prüfung - read more about ithere.)

*

die lighting in this shot is deliberately awful, about what you"d expectfrom noontime sunshine here bei the Atlanta, GA area. (In fact, die colorbalance has actually been chosen to pretty well match the hazy sunshine below inmid-August.)

the reason zum the harsh lighting is to provide a echt "torturetest" des how cameras handle conditions des extreme contrast; and inparticular, exactly how well they carry out holding onto highlight detail.

look for:

Overall color: corresponding summer sunlight here in the South,the lighting in this scene is a bit more yellow-tinged 보다 that inmany parts des the country, or an the fall or winter. - dafür there maybe bei overall warme cast to die color. That said though, there"s a fairrange des color represented in the bouquet, presenting a challenging challengefor ns cameras. Weil das some reason, the blue flower seem particularlyhard zu handle, with numerous cameras er hob them together purple. (In reallife, they"re a irradiate shade of navy blue, with just a bit of purplein them.)Skin tones: die overall slight warm cast wollen tend to leavethe model"s skin tones a little on die warm side together well. Nonetheless,look to see if herstellung skin appears overly pink or if they schutz a too-brighttinge of yellow: part cameras oversaturate skin tones (make their colortoo intense), top to an almost sunlit look. A wenig oversaturationcan make for a more "healthy-looking" complexion, yet it doesn"ttake much variation for skin tones zu look unnatural.Highlight detail: When the model"s skin tones are punkt a moreor less normal level von brightness, how viel detail tun können you see bei hershirt? Does it blow the end entirely zu white, or tun können you still see thecreases and folds an the fabric?Overall contrast: Most consumer digital cameras produce bright,contrasty images, because that"s what many consumers like. Unfortunately,under glowing sunlit conditions, countless such cameras produce bild withlittle or no to mark detail, und dark, plugged-up looking shadows.Shadow detail: the area under ns flower bouquet is an quite deep shadow. Does die camera an question maintain good detail here, through low bild noise? to see, freundin may need zu download the image und play through it an Photoshop(tm) or one more imaging program. Brighten ns image, and see how far detail extends into the shadows. Photo printers are generally much better punkt showing shadow detail than room CRTs or LCDs, deswegen you"ll want a camera that preserves good detail here. Ns ability kommen sie boost brightness without encountering auch much image noise zu sein important if freundin ever have to "rescue" in underexposed bild on the computer.

This shoot duplicates indoor shooting conditions in most us homes, withfairly bright glow room lighting. Die challenge here is weil das thecamera"s flash zu blend normally with die room lighting, and producegood, neutral shade overall. - some cameras wollen be overly influenced bythe room lighting, even with their flash enabled, und the result willbe a strong orange cast. Another common failing is zum the highlightsfrom die flash kommen sie take on bei unnatural bluish cast.

Finally, exposure zu sein important here, und frequently a difficult challengefor ns cameras. The model"s white austrian is central in the scene, reflectinga lot of die light from the flash right back at die camera. Together a result,most cameras underexpose this shot, und require some optimistic exposurecompensation to produce a great result. - and that"s in important considerationin itself: Does die camera even permit adjustment von its flashexposures? numerous do not. This photos room a difficult exposure challenge, ifthey come out OK, the camera bei question kann probably it is in coaxed right into deliveringa great flash exposure of any topic within that is range.

klasse too, the the normalerweise flash shooting (as protest to die slow sync one,if ns camera uses that feature) möchte be high solution rendered, any subjector camera activity frozen by the fast pop des the flash. That provides thisshot a good one to look weil das the effect of over-aggressive noise suppressionin the model"s hair.

ns incandescent lighting used an most US dwellings actually has a verystrong yellow color kommen sie it. Our eye have in amazing ability kommen sie ignorecolor casts prefer this, something digital cameras struggle zu emulate.

the incandescent lighting used zum this shot is thus not only an extremely commonhere in the US, but also very difficult zum most digital cameras to dealwith. While we more than likely want a little yellow color zu remain inthe image (to convey some of the mood des the original scene), too muchwill look at unnatural and distort colors.

many cameras" auto white balance systems have a an excellent deal von difficultywith this shot, however many incandescence white balance settings struggleas well. (It seems that plenty of cameras" incandescent settings are actuallycalibrated to ns tungsten lighting used an professional studio systems,which isn"t practically as warm-toned as common household lighting.)

If you intend kommen sie do viel shooting indoors after dark, pay mindful attentionto this test, as cameras differ widely bei this regard.

ISO Series:"ISO equivalent" refers kommen sie a camera"s irradiate sensitivity. ISO200 represents twice ns sensitivity of ISO 100, an interpretation that freundin canuse a shutter rate that"s double as fast. Higher ISO setups are oftenrequired to get any picture at all wie shooting ~ dark, yet evenin full daylight, making use of a higher ISO can help you freeze fast action.The problem is, boosting a digital camera"s ISO also increases imagenoise. In practical terms, this way that higher-ISO bildern often can"tbe used kommen sie produce prints as big as lower-ISO ones. Die tricky thinghere zu sein that high-ISO images often look viel different when printed atvarious sizes 보다 they do when viewed on-screen. In particular, zum anylevel of bild noise, you"ll often discover that if noise zu sein quite evidentat bigger print sizes, as you reduce the size von the prints, there willcome a point where it suddenly ceases to be bei issue. We routinely printhigh-ISO picture from the cameras we prüfen on our studio press (currentlya Canon i9900) weist a range des sizes, und report our findings. If you"reinterested bei investigating ns effect of image noise zum yourself, don"tjudge cameras" performance by how their bildern look on your CRT/LCD, viewedpixel-for-pixel. Rather, download the test shots linked in the table belowand output them top top your very own printer, so you tun können see how prints of varioussizes wollen actually look.

One additional klasse about this particular prüfen series though: Becausethese bildern are shooting under family incandescent lighting, the camerahas zu boost that is blue-channel signal rather a bit kommen sie get rückseitig to a neutralcolor balance. Since die blue channel is generally ns one with the mostnoise, this provides this shoot a echt acid test des noise performance. Noiselevels an high-ISO shots taken under daylight problems usually won"tshow as viel noise. (See the "Far Field" test for examples ofhigh ISO shots captured in daylight.)

House Shot
:
*

Like several of our tests, these bildern are actually photos of a high-resolution poster, shoot under studio lighting. The shots zum this camera were captured with ours third-generation home poster, which was assembled indigenous 45 different 11-megapixel images, shot with a very high-quality lens, and then stitched together into a einzel image. Ns resulting bild amounts zu about 450 an extremely high-quality megapixels. This should schutz sufficient detail to comfortably an obstacle cameras up zu at the very least 80-100 megapixels. (And also with higher-resolution cameras, we believe that die camera lenses themselves would certainly be an ext likely to limit resolution 보다 would die detail bei the poster.)

Why did us choose to shoot a picture von a picture? die idea was to zeigen a common subject (a house und surrounding foliage) an a way that would certainly be absolutely consistent from camera to camera. Any type of outdoor subject is going kommen sie vary significantly from day to day, as the lighting transforms with the weather, atmospheric conditions, and season. Shooting a poster lets us compare bildern from cameras shot weeks, months, or even years apart, with die sure knowledge that nothing has adjusted from one shot to another.

Things kommen sie look for here space fine detail, as seen an the foliage and tree four against ns sky, sharpness bei the corners, and the preservation of subtle detail an the shaded brick patterns. - many cameras with overactive noise suppression severely blur ns brick fads that are an shadow.

 

Far-Field prüfen 2
*

While ns House poster in the shot above provides pure repeatability from test to test, it doesn"t offer die range of brightness (dynamic range) that the original scene had, nor does that contain ns nearly infinite range von fine detail found in nature. Zum these reasons, we shoot in outdoor photo von a building, to provide a more difficult (if much more variable) subject zum the cameras. Until Summer von 2011, we used ns original home from die House poster for this "Far Field" shot, but die ever-encroaching trees made it less und less useful. Die coup außerdem grace for that subject was when die neighbor throughout the straße relandscaped his yard so we could no longer shoot native our original position.

In place von the original house, we"ve switched to using ns Roswell, GA city Hall building, which uses many of the elements des the original far Field subject, but bei a setup where we"re guaranteed access into ns future, and without ns threat von trees at some point obscuring the building. In this shot, we look at how the camera handles rendering of subtle detail (the bricks, both in the sunshine and bei the deep shadows under die entryway roof), just how it handle bright highlights (the white columns and reflections from ns dome), und shadow detail (in the dark locations beneath die shrubs on one of two people side des the steps).

Note though, that since this is shot outdoors, die character des the light zu sein unavoidably going zu change fairly a bit, depending on ns atmospheric humidity and the time des year. - you thus shouldn"t depend on it for absolute comparisons betwee cameras, because it"s unlikely that conditions wollen be exactly the same native one prüfung to the next.

Pine
*

Our existing Far-Field shooting lacks one attribute that we discovered invaluable in the initial one; namely the pine foliage the was bei the background von the old subject. Die pine foliage provided very fine einzelheiten that we could so count top top being ns same year-round. No various other shots us capture detailed this combination des fine einzelheiten at a distance, so we added a new shot ("PINE" in all die filenames) of a big pine tree near our office, shot weist roughly die same range as the pines an the alt Far-Field shot, dafür comparisons can blieb be made against older images. Usage this shoot to see how well each camera handles really fine detail, both an high-contrast cases (the needles against ns sky) and in low-contrast people (the needles against each other). Ns tangles of small branches against die sky are also very revealing.

The combination of the FAR2 and PINE shots administer a riches of die info about cameras" image-rendering prowess with natural subjects shot punkt "infinity," filling testing needs that can"t be entirely met with studio shots alone.

 

Lens Zoom Range

Simply reading "3x zoom range" doesn"t execute a gewächs to help sie visualize what the means. It so says nothing regarding just how wide the wide-angle ende of that selection is. To give you in idea des exactly what each camera"s zoom lens does, us shoot this series des images, showing results weist maximum vast angle, preferably telephoto, und telephoto with "digital zoom" enabled (when supported). (Note of course though, that so-called "digital zoom" just crops out and enlarges die central pixels of the image, achieving raised size at die cost des reduced resolution.)

Macro ShotStandard Macro Shot

Macro with Flash
*

Many space interested an close-up or "macro" photography. This prüfung shows the best outcomes we could attain using each camera"s macro mode. What to look for:

Minimum Macro Area: What"s the smallest area that the camera kann photograph? - we calculate this and report on it in the test Results section von each review.Softness in corners?: The bild from most digital cameras get reasonably soft when shooting bei macro mode. Part are much better than others though, you kann sein use ns texture von the document fibers or ns details in the dollar bill to compare edge sharpness betwee models.Flash performance in macro mode?: Macro mode flash performance varies widely bolzen cameras. Some can"t accelerator down the flash enough, rather throttle down enough, but have very uneven lighting, while others have lenses that task into the path des the flash, casting solid shadows. The Macro through Flash shot right here will nur you what kommen sie expect.

Low-Light Tests

short light photography is bei area where there space really huge differencesbetween digital camera models. This prüfen starts weist a irradiate level aboutequivalent kommen sie typical stadt street lighting at night (one foot-candle),and then progresses under from there, each successive test being at halfthe light level des the preceding one. Sie may deshalb see die effect of poorlow-light autofocus bei some des these shots, back we usage a differenttest setup to check autofocus performance much more directly. (The resultsof which room reported on in the hauptsächlich Test results section.) jene tolook zum here include:

Exposure limit: What"s the darkest level a camera tun können handleat every ISO setting? If ns leftmost images are sensibly bright, thecamera must do fine through typical city night scenes. If you"re shootingin ns more dimly-lit suburbs, you"ll need a camera capable von producinggood bildern one, two, or three measures to die right des that.Autofocus Limit: exactly how dark kann sein you shoot und still obtain well-focusedpictures?White Balance: Does the camera"s white balance suffer weist lowlight levels? (Many do.)Noise Levels: look at the photos, publish them on your very own photoprinter. How huge a print tun können you make hinweisen acceptable quality levels,at assorted ISO settings und light levels?Detail loss zu anti-noise processing?: carry out details bei the whitegauze und even in the lettering top top the test targets suffer hinweisen lowerlight levels?

(Note: If you"d like to use a light meter to inspect light levelsfor subjects you might be interested in shooting, a light level von onefoot-candle corresponds zu a normal exposure of two seconds punkt f/2.8 andISO 100.)

Flash selection Tests

Digital camera makers oase gotten much better with their flash-range ratings.In the early days, plenty of cameras had rather "optimistic" flashrange specs, zu put the politely. This days, ns manufacturers it seems ~ tobe toeing the line. (No doubt weist least bei part because des tests choose this.)Consistent with our philosophy des testing worst-case conditions, thistest deshalb involves some use of each camera"s zoom lens. Flash selection isgreater weist wide angle focal lengths than weist telephoto ones. If you"reshooting at the wide angle end of the lens" range, freundin might get betterflash variety than what"s bezeichnen here. - however you"ll never get a nasty surpriseif freundin let the prüfen shots listed below be her guide kommen sie flash capability.

The test target here is our "new" speed range/uniformity target, zuerst put right into service an April, 2009. To avoid potential exposure difficulties caused by the target itself, we"ve gone to a mostly empty grey target, v a reflectance of 18% (matching ns theoretical level that most exposure metering system assume zum average step reflectance). Ns white and black chips allow us inspect white und black points in addition to ns mid-grey des the target itself. The concentric circles space a intuitive guide zum flash falloff, marking points 25%, 50%, and 75% of the way from die center to the corners von the target. The bold schwarz framing point out indicate die corners des either a 4:3 or 3:2 aspect ratio, for those shots an which we"re checking flash uniformity. (See below.) zum consistency von exposure, ns target zu sein mounted bei front des backdrop record that also approximates a 18% grey.

Manufacturer-Specified flash Range

Lately, countless manufacturers specify flash variety with ns camera collection to auto mode, an which ns camera zu sein free kommen sie boost that is ISO setting kommen sie help increase ns flash range. This does increase ns range, yet it"s simple to oase too much of a great thing: too high bei ISO can leave sie with auch much bild noise. Die variable ISO setting deshalb means that there isn"t in easy way kommen sie compare the range with die fixed-ISO shots in our typical flash selection series. Dafür now, we deshalb test the flash under ns manufacturer-specified problems (whatever they might be, however frequently with ns camera collection to automobil mode), und the look weist both how brightly die scene ist lit, and how much bild noise ist present an the result images.

Flash range zum SLRs wollen vary with die lens offered (depending on die maximum aperture), dafür their speed range is commonly expressed together a overview Number, or GN weil das short. Ns guide number zu sein a distance, in either feet or meters, hinweisen a offered ISO. To find ns maximum speed range punkt a offered aperture, just divide ns guide number über the aperture. Zum instance, a guide number von 56 feet would certainly translate kommen sie a range von 10 feet with a lens collection to bei aperture von f/5.6. Ns range would certainly be double that if you had bei f/2.8 lens (56/2.8 = 20).
