With Photoshop, how is it possible to keep the structure of this woodworking:

enter image description here

but replace the wood texture by another, like this one:

?

I can imagine it's possible with two layers, and a special "blending mode" for each one, I have tried a few, but haven't found the good one(s).

(The "woodworking structure" is probably defined by the dark lines / contours)

    In Photoshop, with the source material as it is, it is not possible. – Rafael Sep 21 '18 at 18:02

    Have you considered a solution using 3D rendering? You mention in another comment that you have many of these to generate. Going 3D might be a more viable option in the long run. – curious Sep 21 '18 at 20:13

  • Very nice, it's exactly what I was looking for! The layer Image is on Multiply, and New Texture on Normal, or the contrary? – Basj Sep 21 '18 at 20:55
  • @Basj depends on the stacking order. Top layer should have multiply so whatever is below it shines through. With this order, it would be the Image layer. Since all layers above Image are in a Clipping mask with image, they inherit it. – Joonas Sep 21 '18 at 22:09
  • Very cool solution, thanks again. Last detail: what tool do you usually use to "Brush a bit over it so its smooth" (there are many solutions, but I wondered which ones are the faster)? – Basj Sep 21 '18 at 22:14
  • @Basj, this answer does get the job done and quickly, but it is quite specific to this panel. Like if you compare the original to the new one, you can still see the texture of the old frame on the sides. The "brush a bit over it so it's smooth" is relying on that same thing. You don't have to make it perfect. If there is some bleed through it may even look a bit more natural than if like the edge is totally sharp. I'm not the OP, but it looks to me he used the brush tool with soft round brush, as in a circle brush with 0 hardness. Sorta like you would use spray paint in real life. – Joonas Sep 21 '18 at 23:53

    This is basically the same answer as given by @BillyKerr: Use a white painted panel. But here only the inner part of the panel has been turned into a white painted panel. The rest is left unchanged and shows traces of the old texture. The real trouble starts if you want to paint the entire panel white. Then it's basically manual painting/drawing. – Wolff Sep 22 '18 at 13:25

I'd say it's probably a waste of time and not worth the effort. The top image is such poor quality that it's unusable anyway.

Instead, just find a white painted wood panel (or take a photo of one), paste it as a new layer on top of your texture layer, and set the layer blending mode to multiply.

Example

  • In fact I have many different woodworkings, not only this generic one, so I'm looking for a solution that works as described in the question. Thanks for your answer anyway! About The top image is such poor quality that it's unusable anyway. it was just an image among many, I have reduced the size here, but I have some in higher res. – Basj Sep 21 '18 at 14:53
  • @Basj - the problem is you'd somehow have to remove the wood texture off the panel first, that's why it's not worth the effort, even if the resolution is better. – Billy Kerr Sep 21 '18 at 14:54
  • For my application it is worth the effort, because I have a few different woodworkings to process. Some of them have a very precise moulding/millwork, for which I can't find an equivalent easily in white on internet. I was looking for a solution that doesn't require to remove the initial wood texture: I thought it could be possible with a processing that keeps the dark "lines" i.e. the contours of the moulding. – Basj Sep 21 '18 at 15:10

    @Basj The problem is the texture in the panel is also made of dark lines - and separating these lines from those you want to keep is not a trivial task. There is a way of course, but it would probably involve painting or smudging out the texture. There's nothing that is going to do it automatically for you - what I say "effort" I mean manual effort, and a considerable amount of time spent doing so. – Billy Kerr Sep 21 '18 at 15:23

    I think what @BillyKerr means is that there isn't really a method or trick. You need to do so much manual painting that you are actually drawing the structure from scratch. That's my opinion anyway. – Wolff Sep 21 '18 at 20:16

There is no algorithm right now that I know that can do what you need using that image.

Even if it was a 3D model using the same wood texture, the shadows are now combined with the wood texture so basically, the information is mixed and lost.

I took a quick look separating channels but the info is sooo contaminated it is useless.

I agree with Bill Ker, but let's explore some things.

If you have the wood carvings on some physical samples try to paint them in white so you can extract the carving itself using proper illumination.

Use a glossy paint so you can extract also the highlights.


But the best way to do that is either using a real 3D program and make your own carvings in 3D or preparing a Photoshop Mockup with different layers.

Here is a possible cross-section to be used as a 3D model later.
