I have a Nikon D800.

Why when I save a max jpeg from Bridge Camera RAW the file size is around 4MB but if I save the same max jpeg file from Photoshop Camera RAW the file size is around 39MB?

    Thank you for your reply.

    So would I have to uncompress the jpeg I saved from Bridge before taking it for printing?


    You don't have to do anything - this happens without any action on your part.

    But if you resave the jpg in Photoshop, it may compress to a different file size.

    Also, editing and resaving a jpg is not recommended, image quality will suffer.

    Assuming that you start out with a raw file, do all the editing you can in Camera Raw, and if furhter editing in Photoshop is needed, do this on a PSD or Tiff, and save a jpg when you're done editing.

    The jpg format uses lossy compression, which means that every time you save a jpg, some information is thrown away. Repeatedly saving a jpg can cause serious quality loss to the image.

    If you have to edit a jpg, do the editing in Camera Raw, or use the Camera Raw filter in Photoshop. This will reduce the quality loss.

    For more information about jpg and other formats, see File formats

    Hi Glennphoto,

    Please have a look at this article as it might shed some light on the topic: Working With Camera Raw In Adobe Bridge vs Photoshop

    Hi Sahil,

    Thank you for your reply. It was very helpful in explaining the differences between the Photoshop and Bridge versions of Camera RAW but it didn’t explain why there is such a big difference in the saved maximum jpeg file sizes (4 mb in Bridge v. 37 mb in Photoshop), using the same raw file.

    Can you help me with that?

    Or maybe you can suggest where I can look?

    Thanks,

    Glenn.

    Bridge will show you the compressed file size (on disk)

    When a jpg is open in Photoshop, it will decompress, so Photoshop will show you the uncompressed file size.

    This tells you that without jpg compression, the file is 37 mb, and that the compression reduces it to 4 mb on disk.
