REAL High End Skin retouching -Pixel Density Matching Technique

<b> Dont let this thread become another discussion on D&B layers and blurring techniques.</b>

I am getting desperate to know some more techniques which we see used in "big head movie posters" and some cosmetics campaigns which leave skin looking perfect but 'natural' and porous.

Starting with an amazing MUA, lighting and photographer is a given.

Does anyone have hints on "Pixel Density Matching Technique" work or use this technique often to make perfect, natural looking skin?

Or use composites 3D and photography for skin and hair replacement?

Re: REAL High End Skin retouching -Pixel Density Matching Technique

on tough skin, I zoom all the way in to the pixels and use a brush with no soft egdes and then use eye dropper tool to copy the surrounding area and go over areas i want to change...use the eyedropper tool heavily to get even result...I darker parts I get better results...especially shadows...

but this isn't something I have read on the net, I just tried it one day, and i t works for my use

cheers

Gerry

Re: REAL High End Skin retouching -Pixel Density Matching Technique

Hi there

There is another option besides pixel by pixel repair...although not always as good.

You can make a pore mask from a hi-res picture of your choice. Below is just a quick example. The pore mask is from Cillian Murphy.

The idea is to remove the existing pores from your picture with your method of choice, then lay the pore mask over the top.

To make a pore mask you make a selection of the area of skin you want. Remove color the apply the High pass filter to just get the pores. Copy and paste this over your smooth skinned picture and change the blend mode to overlay. Then sharpen to bring out the pores.

Nice one Gerryyyyya yes i've done this too
Perhaps another way would be too use a tight "Select colour range" then CMD+J to copy only that selection then use levels to match the tone to surrounding px…? I guess that only works for similar colour bits though.

Dude, this sounds excellent. I've often used HP filter to add detail back into a smoothed image… i'll be giving this a go asap. Now to find some good pores… Pores for thought.

Re: REAL High End Skin retouching -Pixel Density Matching Technique

daviskw: nice one...so, where to find good pores? anyone?

ETERNAL: I've maybe made myself missunderstodd here, but I don't do a whole image use only the pixel by pixel method...first: i'm not that good, second it takes me a whole lot of time to just do small areas... I have one picture, the first I tried it on...but, I don't have the psd to back it up...it's only a before and after image...

find it here:

Pore mask? Is it the 2D equivalence to the 'bump map' that 3D artists use to texture 3D models? I use bump maps made with noise and painted grains every time when texturing my 3D models. I've also used the same bump map for retouching, but never liked the result much. Never thought of making the map out of real pores. Thanks for the tip. Very interesting.

I use Maya. Poser only allows the users import pre-made models and has no modeling capability. I like to build 3D models/objects/structures and texture them more than anything else, and Maya offers everything one needs in the production pipeline. The only con I have is that the learning curve is higher than anything I've ever encountered. It's very slow going for beginners.
