Our scanners produce large digital file sizes for best quality. A 4,000 dpi scan of a 35mm frame at 48-bit colour depth will result in a TIF file of about 120MB (see table on right), much more for medium format film. Using JPG file compression, the same scan would result in a file of only 8-10MB file, but some loss of quality would occur.
JPG images have half the colour depth (number of colours) of TIF files. Each time a JPG is edited and then saved, further 'lossy' compression occurs as the image is recompressed by the algorithm.
If you plan to edit your images, we recommend TIF files. Remember that each time a JPG file is edited, a further loss will occur, leading to artifacts in the image. If you simply need your images for web or AV presentation use only, then consider asking us for JPGs.
