Larger PSB file

I use GFX 100S with multiple layers and frequently end up with layered PSB files that are up to 7GB.

Current workaround

I save a collapsed TIF file to have it show up in Capture One

    Hi Jack, PSB files have a theoretical limit of 4 exabytes.

    Capture One doesn't impose a maximum file size, however we limit editing to 65000 pixels on the long edge (which could be well over the 7GB you mention).
