This is a super-easy tutorial on how to make something that looks like if it was a game title screen from 80s and early 90s =)
- So go ahead and open the image in GIMP
- First thing we need is to make the image really small so that it looked pixelated as hell. So navigate to Image -> Scale Image and set Width (or the biggest dimension) to 64, click away and it will calculate the second dimansion (If it doesn’t just click the chain link symbol so that it becomes connected and repeat).
make sure the Interpolation is set to Cubic. Then click Scale.
- We need to add this image some contrast so that it looked more clear when we finished. Open Colors -> Brightness-Contrast and play with sliders a little until you see this image more clearly and press OK
- Older computers and consoles had a limitation of the amount of colors shown simultaneously on the screen. So now it’s time to reduce the amount of colors in the image. Go to Colors -> Posterize and set Posterize levels to 8.
- Then we will scale it back to original size. Go to Image -> Scale Image and set width back to 1280 (or your desired size). Here is the trick though: you need to set Interpolation to None this will not blur the tiny pixels and scale them as is.
- Done! you may save or export your image.
