I'm working with a very large file at the moment in PS CC and I'm running into all sorts of problems. The file in question is a .tif of 655mb. It has a resolution of 9425 x 11872 with a dpi of 1200. At first i had some low memory errors. I have 8gb ram and photoshop is using 4700mb. So i increased it so PS now uses 7000mb. I worked on the image but now i can't save it. When i try to save it as .psd i get an error the file size exceeds 2gb. When trying to save as a .tif with layers i get an error the file it exceeds 4gb. When i try to seve it as a .png it simply says "not enough memory to save". Please help!
