  • How to use an 8bit effect in 32bit ?

    Posted by Bernhard Rieder on January 10, 2010 at 4:27 pm

    Hello,

    I have some effects that seems to work only in 8 and 16bit.
    I would like to work in 32bit –

    is there any way I can get the effects in 32bit done as well ?

    thank you

    Just so that you’re clear on what it means that some effects work in certain color depths:

    The effects that don’t work in 32-bpc can still work on a layer in a 32-bpc project. The effects just don’t preserve the precision and over-range values that it is possible to have in a 32-bpc project. If you were already working in 8-bpc and only switched to 32-bpc to fix certain problems, then this limitation might not be an issue for you. For more information about color depths, see this page: “Color depth and high dynamic range color”

    If you do want to preserve as much of the over-range information in a 32-bpc HDR (high-dynamic-range) image as possible while using a low-dynamic-range effect, you can use the HDR Compander effect.
