Wish List / Linear plane manual background extraction
« on: 2019 March 20 13:13:24 »
I'm currently processing a close up of the Rosette with no reliable background points.  I eventually managed to get what I think is a decent result with just 4 points which I figured should be about the same level.  However, it made me think if there could be a better way of doing it.

How about if you had a manual background extractor that assumes that the gradient in the image is a tilted linear plane.  You could adjust the tilt of the assumed plane to be deducted from the image via a real-time preview until you got a result you're happy with.  You could control the direction and amplitude of the tilt with either a virtual joystick or x and y sliders all centered at zero.  You could run it on RGB/K or on R, G and B individually.

Sound like a good idea ?

Wish List / simple transparency/fade process ?
« on: 2017 January 18 04:03:43 »
Hi there - long-term user, first time poster (I think).

In all my work flow, especially all the non-linear HDR and sharpening stuff, I find I end up using the same piece of pixelmath over and over again, along the lines of (a*opacity + b*(1-opacity)) to enable me to either fade an effect I've just done or to get a mix of differently processed versions.

Just wondering if there is a possibility of having a formal process to do that - it could have:
- real-time preview
- either two target images, or the target image and its last swap file
- transparency slider
- fully maskable
- applicable to whole image, or to R, G, B, L, a, b, chrominance etc layers


What do you think ?
