A short time ago photos I open in Photoshop cc or Elements 11 open in huge size files. I realize that these programs open the uncompressed files, which are larger than what shows on my harddrive, but when a 6 MB file opens as 51 MB, that seems excessive. As I work on the photo, the file rapidly become unworkable, using huge amounts of memory. Can anyone help me with this? I have been on an Adobe forum and haven't been able to resolve this.
