Thumbnail quality (SOLVED)

Post#1 by RJKD » 01 Nov 2016, 11:24


I'm just starting out with a digital camera DSC-H400. My image size is 5152 x 3864. I am trying to make thumbnails but can't preserve quality. (3 elements here, I'm new to the camera, fairly new to Gimp and not the sharpest tool in the box). Could I be approaching this from a different angle? Thank you.

I don't know too much about thumbnails.
But aren't they just resized smaller images of your images. If that's the case then it'll always be whatever the resized image is, it'll lose information.
I might be wrong though.

Your monitor displays aprox 70 pixels/sq inch. so when you try to squeeze 20million pixels into a space that's say 36,000 pixels (600x600), your going to have some quality loss. Your best bet is to (using GIMP) "scale image" down to a reasonable size, and then export it at max compression before you upload it as a thumbnail. Once it's shrank, you won't be able to expand it without significant quality loss, so thumbnails should only be used as an example of the original image. The real question is, why are you using the thumbnail? Is it for advertising, or for personal use? I use thumbnails as a teaser to the link of the original image, a custom desktop icon or as an avatar pic, where I expect image quality loss... there's a reason your desktop isn't populated with tiny beautiful images instead of blocky simple icons, and it's that your compy just isn't built to do that!
