Photographs have been used for over a century now for capturing moments of mankind and things around him, although photography dates back to 4th century B.
Outback Print recently introduced a new Printer Evaluation Image. First off, a special thanks to Bill Atkinson for allowing the use of many of the image frames from his original test image.
Since we already know from experience what to look for, it would have been akin to a re-invention of the wheel to create a test image with different image patches. What I look for Usually, the Essay on digital photography thing I look at is the gray ramp.
Here I want to see a smooth transition from the full black to full white without notable banding or color casts. Here, with the gray patches more separated in tonal value, it is easier to see color shifts that move away from neutral gray; in a perfect print these should appear perfectly neutral when compared to their immediate neighbors.
Next I look at the bottom patch ramp, specifically noting the minimum black and maximum white patches discernable. Note these are surrounded by full black and paper white, and that a colorimeter can likely read differences beyond what you can see, especially in the black patches.
For my own use, I typically base my comparisons on what I can I can detect with my naked eye, since that is how I view prints. However, this becomes somewhat subjective and others may want to measure those values so they have a more empirical data point. Note too that the white point goes off the edge of the test image.
This is done on purpose to evaluate printers that lay down gloss or other clear overcoats. Also note that there is a full black patch in the upper right corner of the evaluation image, large and conveniently placed to more easily read and measure dMax when using a colorimeter. Next I look at the gamut ramps.
These are the colored stripes in the lower left of the test image. Here the transitions should be uniform. If there are issues with the profile, they will show up as banding or even inversions along these ramps. Note that almost all printers and profiles will usually generate some banding somewhere along these color ramps, but it should be relatively minor.
More critical is an inversion, where the brightness first increases then decreases before increasing again. I also confirm that the first three primary colors actually appear as Red, Blue and Green to my eye and not some iteration or approximation of those primaries.
The most common problem with inkjet prints is the Blue, which will often appear a bit purple. In the RGB patch, I look for separation between the adjacent hues.
Many printers or their profiles and most monitors have difficulty distinguishing between some of the greens and cyan and that issue shows up here. These can also be read with a colorimeter if you want the empirical data. Next I look at the skin tones in the Kodak test patch.
If the profile is off, you will know it right away because the skin tones will look wrong. Moving up to the top center, I look at the sky gradient in the tear-drop arch shot.Digital photography is a continual learning process, as APTE Professional Education Development Group states, Digital photography can be used at every phase of an instructional unit.
If used at the beginning, students might take photographs for a particular purpose, such as recording a class field trip, and write captions for each photo back in.
