I use the Sinar f2 4x5 for landscape shots in the Rocky Mountains. I use Velvia 100 and scan them in on an EpsonV750 Pro scannner. I so scan both slides in at the same settings including dimensions and file size. I have tried wet and dry mounts, neither have made a difference. I have yet to find a time when both of these images will align perfectly in Photoshop. Anybody have an idea where I'm screwing this up?

Thanks in advance,

Rick
