It would be great if ArchiCad utilised the Core Image filters available in Mac OSX.
So for each 3D view in a layout sheet you could easily adjust levels, saturation, brightness, exposure, sharpness etc without any performance hit on archicad (as it is handled by the OS) and reducing the need to save images and edit them in photoshop.
This kind of thing is available in keynote, pages etc, and would be super useful for archicad...
ArchiCAD 19 (6006)
