make subject pop? - echoes - 12-15-2019
I have various photos that are watercolor/marker---each photo is mostly a bland white with a color subject.
I'd like to:
1. convert the bland white background to #ffffff OR transparent
2. make the subject colors more intense
I have several photos, so ideally I do *not* want to manually edit out the subject with the selection tool.
Any suggestions?
Here's a sample photo: https://ibb.co/F0RQ9Cd
(Note that the colors here are really bad, adding a sample photo just for illustration.)

Your backrground is a bit uneven (more light on the right). A scanner is better than a camera shot (scanners are cheap), or, next time, overexpose the shot.
This said:
- add a bit of contrast with the Brightness-contrast tool (watch for color changes on the line edges, stop before this)
- with the Levels tool blow out the bakcground (drag rightmost handle to the left)

Back to it. Found a way to even out the lighting, and af the same time whiten out the background:
- With the color picker, sample the darker background (bottom left corner) to set the foreground color
- With the same tool, sample the lighter backrgound (top right corner). Ctrl-click to set the background color
- Add a transparent layer, and set it to Divide mode
- Set the Gradient to FG to BG (RGB)
- With the Blend tool create a gradient ftrom the bottom left corner to the top right corner
- If happy with the result, "freeze" it with Layer>New from visible
- If needed you can add some saturation to that layer with Color>Saturation

That example, colours are a bit bland to make anything 'pop'
Not the automatic fix I suspect you would like but the Gimp gmic plugin http://www.gmic.eu can get a sort of correction in one go but it is very user interacive, using color curves (CMYK) filter. Looks like this: https://i.imgur.com/5nhF4TY.jpg Had to adjust 3 of the curves
