Re: Waves in scanns

Are you able the make very fine adjustments of the frequency?

Through the graphic card for the projector? For example 61hz?

Of the camera fps rate?

I am not talking about regular f-stop or shutter speed, but very fine adjustments.

In David live view, when setting up calibration, zoom in (mouse wheel). Is there any flickering, lines going across the screen, etc... or do you have a rock solid image? You must have the most stable image in live view before you start scanning.

Re: Waves in scanns

What he means is monitor refresh rate. Some gfx cards have fine adjustment for this option. You can set refresh rate to 59 Hz, 60 Hz or sometimes even in between.

I made some scans recently with SLS-3 and software version 5.2 Oriignal HP cams, rolling shutter and there are no lines in scan.
