File Type Help for Digitizing Slides, Negatives & Pictures
File Type:
JPEG and TIFF are both industry standard file formats and readable on Windows, Macintosh, and Linux systems.
TIFF files are extremely large when compared to JPEG files and therefore require significantly more CD's / DVD's to hold the images. Before ordering TIFF format, make sure that your computer can handle these large files. The JPEG format is the most common and uses a technology that compresses the image size to save on disc space. The downside to JPEG files is that repeated editing and saving will reduce the image quality. We use minimal compression and the highest quality setting on all JPEG images. It is virtually impossible for all but a professional expert to see a significant difference between a TIFF image and our JPEG images.
