Re: Convert 8 to 16 bit for processing?

The advantage of converting to 16-bit (using Convert) is that the low-order bits are filled in with random data rather than just zeros. This makes for smoother gradients as it fills in the gaps between adjacent 1/255 steps in brightness. The difference may or may not be visible, depending on the tra...

Re: Warp and Scale Factor 1:1

No there isn't -- but, as you probably know, you can do this using the Crop transformation instead.

The scale factor in Warp is computed as the ratio of the area of output image to the area of the cropping rectangle in the input image.

If Any Channel Clipped is selected, highlights are indicated anywhere the R, G or B channel exceeds the threshold defined in Preferences. If All Chan...

Re: Composite overlay mask removed on reprocessing

OK, I believe I have found and fixed the problem for the next release -- the code was checking to verify that the size of the mask was the same as the size of the image it applied to. In the case of a mismatch, the mask was being reset. This protects against the case where you change the input image...

Re: Composite overlay mask removed on reprocessing

I can reproduce the problem using your workspace files, but as far as I can tell, if I try to rebuild the workspace from scratch the problem does not happen. Will need to investigate further.

Re: Composite overlay mask removed on reprocessing

Still not seeing the problem here. Are you using the latest version? You can just email workspace files to me at jsachs@dl-c.com. I believe you can upload zip files -- to create one just right click in Windows Explorer and select New Compressed Folder from the popup menu. Name it and then drag the f...

Re: Composite overlay mask removed on reprocessing

I am not able to reproduce this here.

In step 2, which Overlay Amount are you resetting?

Can you post or email me a workspace script?
