How to use an 8bit effect in 32bit ?

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.
