Scan Sizes for Standard Prints

The following file/print size chart should be used as a guide for producing optimal quality prints on our Lightjet digital enlarger and Fuji Frontiers (file sizes shown are minimums). We can often generate prints from smaller file sizes, but you may experience some degradation in image quality. If you need to produce a digital file from your film, A&I drum scans are a great way to get the resolution you need for a large print size. We usually recommend that film be scanned at 300 dpi in order to provide some leeway for cropping.

Scan sizes are listed for RGB tiff files only. Calculations are based on Adobe Photoshop.
