Hi, I'm new here, this is my first time posting. Hope everything is okay.
Go from this
to this
For this icon I am using GIMP, it is very easy and therefore probably translatable.
Step 1
Take your image and crop it, then resize to 100x100. Next copy the image twice, set the first one on soft light and the last on screen- then merge the layers. It should look something like this:
Step 2
Next I used the white balance tool (colour-auto-white balance) and then sharpened the image. I then used the blur tool to smooth the skin and the sharpen tool to make Finn's eyes look a bit brighter. Then I used the dodge/burn tool set on dodge all over the icon.
Step 3
Next is the colouring.
(set to soft light 23%) =
(set to soft light 25%) =
(set to overlay 37%) =
Step 4
Next gradient and light texture (gradient made by me, can't remember who made the light texture, if you know let me know so I can credit them)
(set to overlay 100%) =
(set to screen 84%) =
And that's it!!
Hope it was easy to understand, if anything is unclear just ask and I will try my best to help :)
Also I would really like to see anything you make!!
