Hi Rô

Thanks, I have studied and (I think) understand that. I guess as more of these snippets are written then the need to understand them fully will diminish. (We can just use them)
However, I like to have some idea of the ‘how it works’.

One (last?) question if I may, My Sepia Filter which (I agree) I should not have used an impulse curve to select shadows, midtones and highlights.
This filter requires some fading or smoothing in the transitions areas. (Like Stroker wrote for Craig’s filter in FM). What would be the best way to do this?


Attached is an example of the 5 point star angles in action. Happy 4th July America.

No problem with the impulse curve.
What happens is that when you put in a value of 100% for the plateau, there's no room for manouver. Change the value to 0%, increase the width to 100% and use positions of -50, 0 and 50.
.......Nice smooth transitions.

The flag looks perfect to me! Great work!!

Thanks Rô, That’s much better

I was never happy with that filter, I will send in an update.
