When you save a photo at as a jpg, quality setting 5 medium, close the photo, open it again, and "save as" it at quality setting 12 high, where do the extra kb's in file size come from.
I mean I know they were there when the photos was first saved at 12, but they went somewhere when saved at 5, (this makes sense) but I never understand where photoshop finds these kb again, when it's resaved at 12.....
The photo itself must be degraded, from saving at 5.... isn't it? Does it also mean that when it's resaved at 12 the high quality of the photo is restored? I wouldn't have thought so, otherwise would we always be told to be so careful with our images, and to keep a copy of the original.
If anyone can answer this I would be forever greatful, I ask it every now and then, but haven't had a satisfactory reply.
