Re: How to copy and use any texture?

Can't it be possible to use the history brush? eg
fill the entire image with the texture and then return back to the previous stage before the filling and then set history brush to paint the texture wherever you want with the opacity and blending mode required.

Flora,

The important thing to remember is that "texture" is a really relative terminology.

First we need to determine what texture is

For example... in a close up beauty image we can agree that texture would be pores, hairs, fur

But if we are talking about a fashion image where the model is placed far in the BG then the pores are not longer the *texture* of the image. The texture in that case would be tonal variation in the skin/clothes.

Having said that we can go even further when relativizing the term and say there's different kinds of texture.

Lets go back to the beauty image of the first sample.

IMO - The skin texture is a summary between small radius tone/light graduations - the pores/hair/fur - and pixel dust (three different radius of detail joined together to create the visual illusion of "skin" - I'm saying illusion because you can fake what it's there in a beauty image by default.

Now.. going away from the Beauty example we could say the same thing about ANY texture in ANY image.
Texture in clothing of an old image: small radius tone/light graduations - fabric material - grain

So... now that we understand that texture is not just ONE radius of information we can say that to move texture from on place to another you need to separate that texture into the different radius.

Using HP for this (specially the apply image based HP or -50 legacy contrast based HP for accuracy) you create one HP of each radius you *think* adds up to create the final illusion and you place one over the other into the area you need to texturize and then use different contrast based blending modes (Linear light/Overlay) to make them work together.

Then, if applying this correctly you can create the illusion of any kind of texture in any kind of surface.

Hope that makes sense to someone

Re: How to copy and use any texture?

Der_W,
thank you so much for your excellent tips!!!
Since coming back, I've been 'experimenting' with nearly all of them!!! In most cases I've had great results... so ... I'll keep on experimenting
The parts I really found great are:
  • heal the blemishes on the High Frequency Level
  • Restore the colours on the 'Color Mode' Background copy placed on top.
Still got to practice on the 'Texture' though.

Thanks again ... and don't get tired of posting your brilliant tips!!!

4personnen,

surely worth a try! Thank you!



Natalia,


It surely makes a lot of sense!!!!

Thank you so much for your excellent explanation about the different kind of Texture and just as excellent tip on using the different HP Layers created on each different Radius for adding the right 'illusion' of Texture on any kind of surface!!!!

Just great ... thank you again

bonzo5988,

great link!!!
Thank you so much for sharing it with us!!!

P.S. .... seems we have scared away the original poster abdul10000

  • Restore the colours on the 'Color Mode' Background copy placed on top.
Oh No! You got the last one wrong, According to Der_W (I did experiment with his color technique):
You create 2 layers between the Hi/Lo layers, one normal and one color like this (from top to bottom of layer stack):
  • hi [apply image] - this is copy of the BG layer
  • color - blank layer
  • normal - blank layer
  • low [Gaussian blur] - this is copy of the BG layer
  • Background Layer [original image]

Total of 5 layers.
You use the "normal" layer to fix color -color variations and such- and you use the "color" layer to add color to area that lacks color or desaturated. You don't move the background layer at all or make any copy of it other than the two you created originally for the Hi & Lo layers

@Der_W: Thank you so much for the color fix tip, this was the missing link in my equation, this was my
lost "holly grail". Thank you so much.

Of course, non of my posts will be complete without, again, thanking Godmother for every thing. Thank you Natalia.

Re: How to copy and use any texture?

abdul10000,

thank you for letting us know .... and very glad we didn't scare you away!

Aladdin,

thank you so much for warning me

Actually, I religiously followed Der_W's instructions while watching his video Tut linked to his post.

Maybe I got it wrong, but what I understood is:

He adjusted shadows/highlights problems on the Low Frequency Layer.
He adjusted scratches/blemishes on the High Frequency Layer.
He adjusted colours on a Background Copy set to Color and placed on top of the stack.

Total of 4 Layers.

Re: How to copy and use any texture?

Actually... you're both right :-).

Doing all the color correction on top is going to give you the most control but will also result in the biggest file size.
So what I came up with, was using a color layer in between the HIGH and LOW and paint on it. That way you don't increase the file size all that much and the high frequencies (e.g. edges) are less likely to be in wrong color (the HIGH layer also contains a little color if you don't desaturate it that'll colorize some parts).

Actually, almost every day I'm improving and developing my techniques, that's why sometimes my tutorials will differ a little
Doesn't mean, the way I showed you back than is necessarily wrong, just that it is a little more complicated/has some disadvantages.

Re: How to copy and use any texture?

@Flora: Thank you for pointing out the Tut link, I was not aware of it. It is great way to learn when you have more than one interpretation. Thanks

@Der_W: Keep up the enhancements coming. Just please let us know where you post them. Color correction has been always my weakest point (and I am sure others too). I really appreciate your effort

Re: How to copy and use any texture?

Most of the tutorials I do are videos, so you can check them on my YouTube-Account (http://www.youtube.com/user/jonaswtuts).
Downside is, that most of them are German, but I'll probably do some more English ones as well :-)

And if you have any questions or need information about certain topics, always feel free to ask ;-)
