Whats the best format for storing grayscale or color photographic images?
If you plan to edit, crop or adjust them, we recommend storing in LZW TIFF format. This format is widely supported and provides good compression. Storing with separate color channels sometimes improves the compression ratio, but is not supported by all applications. For compatibility with applications that do not support LZW TIFF, we recommend uncompressed TIFF or PNG. If your image is in “final form,” and you do not intend to edit it further, JPEG is a reasonable option for storage. It offers excellent compression, but there is some loss of image accuracy associated with it. We recommend a quality setting of between 70 and 90.
