Sharpening after downsampling is normal - the downsampling operation makes the image more fuzzy as a natural consequence, so you generally have to sharpen afterwards. Since you need to do that, there's no point sharpening beforehand as well.

[Gimp-user] the order of downscaling in a image editing workflow.
hi, i usually need different size of image for different situations ( web publish, sharing with friends, etc. ). so it seems practical to complete all editing on the image before do the downscaling. quite often, i will use a utility such as ImageMagic's convert to do the downscaling and converting to other suitable formats. but, gimp's tutorial suggests that one should do some editing tasks ( such as sharping ) after downscaling ( or upscaling ). i want to know why and how do you do that ? what i expected workflow of image editing is: 1) improve contrast and color balance in gimp 2) despeckle 3) sharping 4) add frame/border 5) downscaling to various of sizes and convert to other formats using a script-able tool. thanks. -- woody ___ Gimp-user mailing list Gimp-user@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-user
