    HI guys. now don't laugh - this is probably a very sad question!!! :( but just checking - if i save a jpeg then go into photoshop.etc and make adjustments then 'save' it - then open it up later and make more adjustments then save it- then open it up a few weeks down the track and make more changes....... is the image losing quality EACH time i adjust it?? so if i opened it up 4 times to make changes would the pic be of lousy quality... would it be better to 'save as'???? Please excuse my "dumb-ness" :lmao: xxx thanks

    Can others edit my Photos:
    Photos NOT OK to edit
    Yes, each time you save a jpg, you compress it, and it will get progressively worse in quality. If you aren't shooting raw, you should.....but....if you won't, then.....you should save your jpgs as tiffs after editing them. Tiffs use lossless compression, and allow you to save layers.

    remember also that tiff's are bigger files and will soon start to fill up your hard drive. so good idea to start backing up
