Usually we consider that 24 bits is sufficient to capture most of the tonalities but it can go up to 48 bits on modern scanners. It’s measured in bits and determines the capabilities of a scanner to capture the nuances of colours or greys on a negative. This one applies for colour scans of course but also for B&W. 3600 dpi is usually more than enough for us and going beyond that will just make image size unnecessarily big without bringing more details. Unfortunately most of these +7000 dpi scanners are just marketing nonsense. For this be effective, the sensors and optics should be both optimised to achieve this density of details. Of course the higher the better but don’t let yourself being fooled by some manufacturers who claims extremely high dpi.

If you are thinking about doing large prints then you should consider a scanner with an high resolution. The most common is of course 35mm but some will accommodate 120 as well. You’ll also be able to scan old pictures with it for example.īeware that most dedicated film scanner are often limited to one format. For example most flatbed scanner can handle 35mm or 120 negatives (Medium Format) and some can even scan 4×5 (Large Format). The type of scanner will also influence the negatives you can scan with. On the other hand, if you are or will be shooting Medium Format / Large Format at some point, then you should be careful about which format is your scanner capable to hold. If you plan on scanning only 35mm, no problem most scanner will be able to scan this film size.
