I'm not an expert in photography but given my equipment, this
is the best I could come up with in 2 minutes of shooting.
I used an old Sony camera with fixed lens stop and no flash.
Lighting was incandescent, and taken at normal reading distance.
ie. eye to focal point ie. 12-16inches
Seeing is Believing

Notice the difference when viewing angle and lighting is unbiased
- the fuzzy image looks like it was taken with a phone camera
This shot was taken close up steep angle.

This image was taken at steep angle to show that it was still
readable under the right lighting conditions and pitch or angle.
Touch screens will always demand a different reading angle than
those without one. With lights turned on, readability increases
20 fold.
