Thank you Gentlemen.
It is almost done - few minor things
John: I got
from Staples
and when I take a setup like this one
I can take a picture with a "stable" background color
however, if the light is not correct, in this case the exposure time was about 15 sec and color is seriously disturbed.
For a quick picture I use the same sheet cut in half and set as follows
so this way I have a very good light and I can limit the exposure time to just a sec or tow.
Usually I set the apperture to be at above 16 (in this case 22) what is giving me desired focus depth. I use a tripod and a wire shutter trigger to make sure no shaking will disturb the picture
I am sorry I used a Spitfire on this Group but since most of us build both ...
