iMac1943 Posted March 27, 2023 Posted March 27, 2023 A friend took a photo of an artwork he made on a white paper. As you see the paper is grey. I tried several adjustments in Affinity Photo but I am not satisfied of the result. The background is still not white. So I'm asking here for advice. Thanks for answering! Luc Quote
walt.farrell Posted March 27, 2023 Posted March 27, 2023 I don't have an answer for you, but I think part of your problem will be that the lighting was uneven, which will make an accurate color correction more difficult.

iMac1943 Posted March 27, 2023 Author Posted March 27, 2023 You are right. So you think, Walt, I will not be able to correct this with Affinity? Quote
walt.farrell Posted March 27, 2023 Posted March 27, 2023 I think it will be difficult. It might be possible, but I'm not sure how to do it. Someone else more skilled than I with color correction may know how to do it.

Well with some better WB function you can get it overall whiter, though when making the whole image entirely whiter here (so not just the background and thus all of the image) then all rect colors will be of course influenced too and so then outshine too! - You may have to seperate the main image from the background (... replace the background, as far as those rect colors by themself have been correctly exposered). Above you can see that the lighting was pretty uneven distributed and crappy! - Let's add, that I'm not sure if it is overall worth the effords for such a bad shot, but that's what you have to decide.

Doesn't the uneven condition of the background indicate that the rectangle colors will also have been unevenly exposed? In that case, any simple WB function probably can't properly correct any of them.

iMac1943 Posted March 27, 2023 Author Posted March 27, 2023 This is artwork and I know from experience that taking a photo of an artwork must be done in a studio with the correct light . The camera has to be set to the correct temperature. Which has not been done here. What not is (correct light) cannot been added. I think affinity cannot solve this. Quote

In that case, any simple WB function probably can't properly correct any of them. Of course it can't the whole, thus I also said reworking just the background to be even. And further then, if the colors of that artwork are known (if you have that in front and can see how it normally looks) one can tweak these seperately (accordingly) to be also more even. - But as initially said, the Q is if it's overall worth the effords here, as that shot is a pretty bad one either way. 29 minutes ago, iMac1943 said: This is artwork and I know from experience that taking a photo of an artwork must be done in a studio with the correct light .

Well what I wonder is, if you already know all that why did you then asked for advice here for that (bad) shot, instead of telling your friend to try to take some much better shot? - BTW it doesn't have to be a full blown studio here, some much cheaper fotobox with some adaptable lighting capabilities, where that artwork would fit in, would do it too here. - So something like these things here (there are a bunch of such product fotography boxes in various sizes and lightings) ...

firstdefence Posted March 28, 2023 Posted March 28, 2023 Masking is probably the only way to get a clean background. Everything can be edited and tweaked White BG for artwork.afphoto If the background is a bit sterile you could also add a bit of side light to tie in with the shadows, subtle but to the eye if feels more correct.

lepr Posted March 28, 2023 Posted March 28, 2023 Luc, attached is a document with saved history so you can rewind then step through it. Essentially, there are two gradients set to Divide mode to counteract the distinct vertical warm to cool cast and the slight horizontal light to dark cast. The first gradient layer is made by horizontally stretching a duplicate of a quite narrow column from near the left edge of the base image then giving it a 5px gaussian blur and setting blend mode to Divide. The second gradient layer is made by vertically stretching a duplicate (Copy Merged, Paste) of a quite narrow row from near the top edge of the composite image then giving it a 5px gaussian blur and setting blend mode to Divide. Before stretching, the Clone Brush Tool was used to remove red ribbon from that layer. 1002159622.afphoto walt.farrell and iMac1943 1 1 Quote

Yes, 2.0.4 plus there is the 2.1 beta when you have upgraded. If you're upgrading all three apps, get the Universal Licence - that gives you a licence for all 3 apps on all 3 platforms. Quote
