As title states, I was wondering how to create this sort of effect in photoshop?
I really like the look and I'm seeing it pop up in different places, yet I can't figure out how to do it on my own, any help would be appreciated!
(This picture is from IGN's best of 2017 if anyone is curious)
Looks like a colour layer applied to a regular layer containing a collage image. Go to layers, add a new layer, change from Normal to Colour layer. Paint within this layer with flat colour to create the hues you want to overwrite the layer below.
Guys, there are too many effects goinig on in the OP's example image. Until we hear back from him on which one of the many effects he's interested in, you would need to break down all the effects and explain them individually.
Sorry, to clarify I was interested in making portraits that are just one color, or mainly one color as each of those portraits are.
If I could take any picture of somebody and make it look like the purple guy on the right for example I would be ecstatic.
Make a selection of Logan and use a layer mask to isolate him from the old BG.
Add a new white background layer below the Logan layer.
Add a Color Fill Adjustment layer using the desired color (purple). Set it's Blending Mode to Linear Light.
Duplicate the layer mask (Hold option and drag) to the Color Fill Adjustment layer. (Note: You could also clip the Color Fill adjustment layer to the Logan layer................whichever is easiest for you)
Lower it's opacity to 44%.
While this technique might get you close, You have to use both the midtones and the highlights...........problem is you start shifting your darker colors in the hair towards the blown out blue side. You don't get the color shifting with a Color Fill adjustment layer. But there's no doubt that it would work as well!
