Determine Optimum Print Resolution of YOUR System:
There are two tests that will determine the optimum print resolution of YOUR imaging / printing system. One tests for your Scanner (print or film) and the other for your Digital Camera.
You will do a series of scans, and/or Digital Camera exposures, at various resolutions and then print them using Photoshop. You will then view the prints to empirically determine your system optimum print resolution.*
The choice of subject for each test is important:
For the "Scan Test" choose a photo that is typical of your work. I use a portion of Kodak's Q-60 Color Input Target. (left photo)
For the "Digital Camera Test" choose a scene that is typical of your photography. Make sure to include some signage or text to help in the evaluation. (right photo)
*It's is helpful to have others chose "the best" print from the series. While working on new films and emulsions at Polaroid, it was interesting to observe how "the best" result was chosen. Print tests were posted by the cafeteria and as the employees walked by they would chose "their best" print. The reasoning was that the employees were more typical viewers than the scientists and the results would not be biased by any expected results.
