    Image going from 16 Bit to 8 Bit in ACR

    Most times I take a RAW file into DXO, save it as a DNG and them open it in Photoshop (which means, as a DNG, it automatically opens in ACR). Sometimes I'll skip the DXO option and just open it directly in Photoshop (the same rule apples re ACR) as a .cr2 (Canon) or a .rw2 (Panasonic).

    Up to this point the image is showing as a 16 bit.

    Fine. So far, so good.

    But, ...............

    Whenever it opens up in ACR it defaults to 8 Bit.

    Why is this happening and what can I do about it?

    It actually doesn't make much difference to me, but I am just frustrated that I don't know what is happening and I don't think it should be happening.

    Donald,
    When you open the DNG in camera raw at the bottom there is a link that details your working space, 8bit, pixel dimensions etc
    Click on it and in the dialogue box change it from 8 to 16 bit and press OK
    Now all subsequent DNG files should open in 16 bit

    Ah ha. So simple when you know how.

    It was in that dialogue box I could see that it was going to 8 bit. I never knew I could click on it and change it.

    Peter, you are my hero for today!
