Hello,

 

I am attempting to swap faces in Photoshop but for some reason my end results are coming out more like a grid then the persons obvious face.

I can just make out their features.

I have the opacity at 100% but it still has this end result.

 

It seems to only be this way for some pictures but not for others.

 

Would anybody be able to tell me what is going wrong please?

I think a fair amount of painting may be necessary to approach the lighting issue.

It can be quite overwhelming to understand all the technical aspects of Photoshop.

 

I have removed some of the images now because I just wanted them up while I was trying to learn, but I didn't want to keep the person face up permanently.

 

When you mention copyright issues, does this mean that if a client asks for something like this, to have their images superimposed onto posters or onto famous people or similar, that there can be a copyright breach involved?

I presumed that if it was for "fun" or creative purposes and not for profit and the clients were not actually passing themselves off seriously as acting in the film etc than it was legal/fine?

 

"may be that the images you want to combine are a not a great fit for the task because the lighting is so different...."

Unfortunately clients can "expect" this though and arn't always reasonably about expectations.

Also they might state they want the texture kept from the original ones skin, or their beard etc...

Without the use of auto blend layers, I'm not sure how to blend that back in without it being obvious.

 

Btw, your edits look really good.

The colour on the Avengers photo face is hard to match perfectly, but all the edges look good and the teeth look more natural by far than my attempt.

Once you have "replaced the face", did you use an eraser fot the edges bit to blend them or some other technique?

 

I noticed you used selective colour and colour fill - I'm not sure how this is done as when I select the face, then add new solid colour fill, all of the colours are not skin tone type shades...

 

Would you mind explaining what is meant by painting please-

ie: does this refer just to using the paintbush tool or something else?

Using someone else’s copyrighted material is not exactly an easy issue. 

Quite possibly your work will never reach the attention of anyone at the involved companies but I am no lawyer, so I am not sure if this falls under »fair use«. And some companies may have more litigatious legal departments than others. 

https://en.wikipedia.org/wiki/Fair_use

 

»Once you have "replaced the face", did you use an eraser fot the edges bit to blend them or some other technique?«

With the SO is in place I applied a Layer Mask to the Group containing it. 

And I painted on that Mask, white to reveal, black to conceal, no use of the Eraser Tool. 

 

»Would you mind explaining what is meant by painting please«

Some of the Adjustment Layers have Layer Masks of their own, so for example to simulate the shadows I used Curves Layers that darken the image but painted them in selectively with the Brush Tool. 

 

»I noticed you used selective colour and colour fill «

By setting a Solid Color Layer to the Blend Mode »Color« one can use it to »tint« the underlying content; and again one may apply a Layer Mask to diminish its effect locally. 

 

I will try to remove the images from my last posts, too.

Without you showing your starting images, describing fully the steps in your method, and showing your result,  no-one can advise you what is going wrong or how you can do it better.

I will take a better screenshot tomorrow:)

 

This is the way that I learnt from watching videos on this topic.

At the end the layers are blended with autoblend and if the old face is not deleted it doesn't work and instead shows the "old face" again after blending.

 

Im using autoblend to try to match the skin tones better.

 


Both Match Colors and Auto-Blend Layers are in my opinion unfit for serious work because they do not offer maintained editability after the fact. 

And placing elements without converting them to Smart Objects before transforming them (repeatedly) is also needlessly destructive in my opinion.

Please provide a meaningful description of what you are actually doing, maybe post screenshots including the pertinent Panels.
