Okay, these are the three tutorials that were requested. I generally just mess around with things and hope for the best, but I tried to get these as close to the icons I posted as possible. These are my first tutorials and I have absolutely no idea what I'm doing, so bear with me here. I'm sure there are also way more efficient ways to do all of this, but I've only been doing this for a little over a month so I'm definitely still learning. This is using Photoshop, by the way.
First we're going from
to
Okay, so the original image:
Cropped to 100x100px:
Then I copied that layer four times and set them all to screen, with all but one of them being 100%, the last one being at 30%:
Looks like shit, I know. After that I added a Selective Color layer. Under neutrals I put black to +30% and under blacks I put black to +100%:
Then I added a Hue/Saturation layer with Saturation being set to +40%:
Then I added a Curves layer. Under green I set the input to 125 and the output to 137. Under blue I have one input at 55 and output at 74 and another input at 115 and output at 142.:
Then I added another selective color layer. Under Reds I set Yellow to +25%, under Yellows I set Black to +54%, under White I set Black to +10%, and under Black I set Black to +18%:
Finally, I added a soft light layer(#42260B)and set it to 50%:
And that's the end of the first one.
Now we're going from
to
Original image:
Cropped image:
Copy image 5 times and set them all to screen, all but one at 100%, the last at 60%:
Selective color layer: Under Neutrals set Black to +30%, under Blacks set Black to +100%:
Hue/Saturation layer, set Saturation to +40:
Curves layer: under Green set input to 122 and output to 135, under Blue set one input to 52 and output to 82 and another input to 113 and output to 152:
Selective color layer: Under red set Cyan to -22% and Black to +30% and under Blacks set Black to +10%:
Soft light layer (6C4214), set layer to 50%:
Selective color layer: Under Neutrals set Black to +100% and under Blacks set Black to 100%:
Use the eraser tool to erase the parts of the selective color layer that covers the faces/bodies:
Use the Brush Tool (#000000) to color in the white at the top of the image and use the Healing Brush tool to remove the watermark:
And that's it.
Finally we're going from
to

Use the eraser tool to erase the parts of the selective color layer that covers the face/body:
Use the brush tool (#000000) to color in the white at the top of the icon:
And you're finished. Not all images take to it the same way so remember to play around with the layers. And if anything isn't clear let me know! :)
