I'm not well versed at all in using things like Photoshop or GIMP, so just putting that out there. I figured this would be a good place to ask. I apologize in advance if I say anything dumb.
Anyway, I've tried searching which interpolation may be the best for this situation but I'm just not finding anything that leads me to believe a certain interpolation would be best. I'm downscaling images in GIMP to really small sizes (102x96 to be exact), changing them to 256 colors, and I'm having trouble deciding which interpolation would be best for this size. I'm downscaling images for a retro game that I'm modifying. As you would guess, at 102x96 the images get quite pixelated. I'm not really trying to retain the most pixelated look possible, because I think most images in the game have a slight blurred look to them. I guess I want to know what the best interpolation for the image size that I'm downscaling to is? It's just that I'm driving myself crazy comparing the 4 interpolation options GIMP has (Cubic, Sinc, Linear, and Nearest Neighbor). I keep finding that there's different things about the images that I don't like, and I can't seem to find a consistent interpolation that I like without second guessing myself.
Also, let me note that I have looked at Difference between None, Linear, Cubic and Sinc(Lanczos3) interpolation in image scaling?, but in my situation I still can't seem to come to a decision. Is it really a case-by-case basis and I can't settle on using any singular interpolation? If I'm downscaling to this size and changing it to 256 colors, what interpolation do you guys think is best at retaining details in the image?
I'm terribly sorry if this post is a mess. Again, I'm not knowledgeable at all in this arena, despite researching a lot about this stuff.
