This question already has an answer here:
I have a Samsung S1050 camera. There are three quality settings - Super Fine, Fine and Normal, which I believe relates to the JPEG compression level. I have mainly used Fine in the past, but wonder if I should be using Super Fine instead. All images are taken at the maximum supported resolution (10 megapixels).
As a test, I tried taking an (almost) identical photo in both modes (Super Fine and Fine) to compare. I found that there was no noticeable difference when looking normally at the photo on my monitor between the Super Fine and Fine in this case. However, when I compared both images with FastStone Image Viewer and zoomed up to the pixel level, I may notice slightly more "dithering" around objects, but it is very subtle. The Super Fine photo was 4.8MB in size, whereas the Fine was only 2.43MB. So is it worth nearly doubling file size by upping the quality setting? I like to be able to archive my photos onto DVD-R, so smaller file size is an advantage.
