Hello Ralph,
Is it true that when you change "Illumination" controls they affect on whole image, not only frame.
It is our decision concerning plugin's behavior.
I seems to us, that we increase effect range by this way.
Source image

Apply to this image "Wood" preset

Now we can "illuminate" this image by some colored light

Source image was changed, it may seem strange to you, when we construct plugin we decide to illuminate whole image, not only frame. At that time we think about it as right decision.
For example: we can apply "Lens" effect: in order to achieve such effect it we must deform source image.

We have no complaints about lens effect and illumination, moreover you can check off both illumination and lens effect in "illumination" and "option" dialog and do not affect on source image , only to generated frame.
Bump map effect on the frame without source image changing


Thank you Ralph for your remarks, we need for feedback in order to satisfy user's requests.
We take into account your notes when will design new version of the Image Frame.
Regards, Dmitry
