Generation Loss from hadto on Vimeo.
We all know that JPGs are a 'lossy' file format, but watch this video, it is shocking! While we are unlikely to save and re-save a photo 600 times, it does make you wonder just how much damage we are doing to our .jpeg files each time we edit a bit and save.
If working in photoshop, saving in one of the Photoshop formats, e.g. .psd (a lossless format) is a way to save images at various points during the editing, before saving the final image as a .jpg if that is the format you need for the final photo.
(NB it's lucky that blog posts are lossless, the number of times I've posted and edited this entry!!)
