I'd like to paint an image from a video game with acrylics on a large piece of mdf board. The image is save on my laptop, is from an early video game system (Sega) and is pixelated. I am trying to resize/scale the image with GIMP so that it will look good when I paint it pixel by pixel blown up on the mdf board. The issue that I keep running into is that my mdf board is 36 in X 24.5 in. The image that I am using is 96 pixels per inch. I can't, nor do I want to paint 96 pixels per inch. I am trying to change the amount of pixels/size of the image so that it is something manageable to paint yet does not look extremely blurry. Is this possible? I've watched a bunch of scaling/resizing youtube videos but still can't figure out how to solve my issue.
I am using GIMP but hoping either a GIMP or PHotoshop person can help me out.
