White balance? #541

Open anonimo82 opened 1 year ago

anonimo82 commented 1 year ago

Hello everyone. Please, is it possible to do white balance with LazPaint? If not, please, will you add it?

It's not a novelty I ask for something and discover it's already there, so I hope this is yet another of these cases =)

Thanks for any help. Regards.

It's not a feature yet. So I take note of it as an improvement.

anonimo82 commented 1 year ago

Thanks so much!! Can't wait to see it realized!!! =)

In the meantime, you can use color shift, or add a layer with the white color you want and use multiply blend mode.

Honestly, I never thought about this use of multiply blend mode. Thanks

circular17 commented 1 year ago

The result will be a good approximation of color balance.

You can use multiply blend mode to set the reference white and conversely the divide blend mode will do the inverse: for example if you have an image where you know the reference color is not the sRGB white and you want it to be the sRGB instead.

Are there any updates?

circular17 commented 1 year ago

Nope that doesn't go that fast. When I get some vacations, I can take some time to add features.
