Okay, so the tutorial. It's actually a modification of my other tutorial
here, just less layers. Yeah, I don't get very creative with my coloring, as you can see. So going from left to right.
to
01. Duplicate the base, set the new layer to screen.
02. Fill the new layer with #89C7E9, set to burn, opacity 86.
Depending on the picture, you might want to lower the opacity of this layer later on if it looks too dark.
03. Fill new layer with #E8E4FE, set to burn.
04. Fill new layer with #F9C9E9, set to burn, opacity 40.
You might want to lower the opacity of this one too if it looks too purple or pink.
05. Merge all layers.
06. Enhance saturation. You can just mess around with the options to see what suits the picture best.
For PSP: Effects>Enhance Photo>Automatic Saturation Enhancement> Bias: more colorful, Strenght: Strong
For PS: Image>Adjusments>Hue/Saturation> Saturation: +30
07. Fill new layer with #89C7E9, set to burn, opacity 70, erase some from the middle with the eraser brush. I'm just doing this to put more depth into the background, you can skip it if you want.
Obviously the results vary with the pictures, these exact options might not look good for every picture so feel free to change the opacities and everything.
