Sp3000 default resolution 300dpi


Recommended Posts

Resolution depends on print size. Bigger print size - bigger file size.

CCD proportions are 1 x 1.33 (  2048 x 1536 ) , so the best results can get when frames have similar proportios.  The best resolution can get if to scan 6x8 frame. On some frames proportions on CCD will be used very bad ( for example 6 x 6 frame, where proportions are 1 x 1 ) . 

Due CCD micro-movement frame will be scanned few times, so resolution will be higher. On big size scanned in 8 positions. Create print size 305 x 405.7 ( for 6 x 8 frame ) and you have the biggest possible resolution.

2048 x 1536 CCD resolution in 8 positions should be very high. Really it will be lower.  CCD sides are not used, some pixel positions will match, so impossible to get the highest resolution.
