With me being a novice, I'm still bumbling around.
What brought the light box up was people on FPN were/are fond of the HP 32# Premium paper. So I got a ream to try out. Well the paper is nice, but it is heavy enough that I could not see my guide sheet under it at all. And without a guidesheet, I can't write a level or straight line. Then I found the light box thread "light bulb goes on" ah ha, that is my solution to the guidelines. And I have a light box for my photo work.
Then I tried it yesterday, but because my light box is 3 inches thick/tall, the work surface is way above the desktop, and I realized that my arm was not supported, not good for my tendonitis
So I figured those of you that do use a light box have probably solved this problem.
Blotbot, I think your idea of a stack of books to support my arm is the only practical one for me, short of buying a larger light box/pad.
Estefa, Yours is 15cm high, and I thought mine was thick. Mine is 3 inches/7.5cm high, half as thick as yours.
thanks all
