Hi Andy
You determine the angle your scanning at , and then set you speed accordingly. Measure the maximum width of your image and divide by the distance from the scanners to the image . Use a scientific calculator with trig functions on it, and do a tan function on the above result. ( Please anyone correct me if my trig is wrong, its been a while ! ) . The result will tell you the scan angle.
Personally, I start at 30 k and back the speed down to get the best image , least flicker combination, and go with that. I try not to get into the numbers game. Since your using stock images you don't know what speed they were written at , or the angle . So play and enjoy.
Nice pics by the way !
I have a few fb3's . Does the dmx operate, or the remote user interface ? I see the sockets are there.
If you do a screen shot of the software, I'll try and point you in right direction.
