8 bit or 16 bit

    I suppose that you send your pictures in jpeg format with sRVB icc profile. If it is the case you have no choice: 8 bits it is.

    The internal color space of C1 is 16 bits. So when you work on your pictures you actually benefit from a 16 bits coding.

    Actually, no. I process my RAW files as both JPEG and TIFF files, using Adobe RGB '98 ICC. I give my clients both JPEGs and TIFFs, all processed at 300dpi, 8 bit. They use the JPEGs online and the TIFFs are ONLY used for prints and edits. I have not tried the 16 bit format TIFFs at my pro lab, AV Partners, in Santa Ana, CA. The 8 bit TIFF prints look so damn good, I was just wondering if it could be possible to improve on great? I do Fuji, Crystal Archive, Luster photo prints only. I never do inkjet or pigment prints. My black & white prints, sepia-toned prints and full color prints are just spectacular. I have tuned my Eizo monitors to give me exactly what I receive from the lab. If I see it on the Eizo, it will be in the prints. I guess I will need to do a back-to-back sample and report on the results. However, this will be like polishing the diamond.

    8 bits is sufficient to code the colors included in Adobe 98 RGB ICC (16 bits is required for wide gamut profiles such as Prophoto).
    In any case I do not think that you will see any difference between 8 and 16 bits on printings, even with the most glossy papers.

    The 16-bit option allows for more latitude in post-processing. It is also preferred option for very critical work, like jewelry.

    Regarding your JPEGs for web, I strongly suggest to put them in the sRGB color space, which is common for web. An image in AdobeRGB viewed through a (Windows) browser may look flat, dull and washed out as the larger color space is not taken into account. Use sRGB only!
