[QUOTE="hark, post: 252548, member: 13196"] Has anyone tried [I][B]Caesium Image Compressor[/B][/I] to reduce file size? After each theater production at the local high school, I make a 20"x30" poster to hang in their lobby. Since I know kids that age tend to like posters, I've tried to figure out ways on how to share these large @20MB files. Last week I came across this free software which compresses the overall size and isn't supposed to adversely affect the image quality. Granted I highly doubt there is any compression software that won't slightly affect the image, but can you tell from these two photos which one is the original and which one was compressed while retaining 80% of the quality? Due to privacy laws, I won't display the poster from school; however, please take a look at this image which shows both an original and its compressed version below. The original file size is 22.9MB while the compressed file is 5.33MB. I uploaded the full size images to flickr. What are your thoughts? Can you tell which one is the original and which one is the compressed image? No fair peeking at the EXIF data! ;) And here is the link for the software if you want more info on it.
