If you have applied levels, a reduce noise filter, and an unsharp mask filter to your entire image thatвЂ™s 5 MB in size, the image will need 20 MB of scratch space. If you count up the number of histories you have where operations have affected the entire image, and multiply your original image size by that number, youвЂ™ll have an approximate amount of scratch disk space the image will need. If your history states consist of operations that affect only part of the image, such as paint strokes, only the size of the tiles touched by the strokes are added to the image size. If your initial image is 500 KB, and you apply Gaussian blur to it, your image will need 1 MB of scratch space.

Each history state that includes an operation that affects the entire image (for example, when you apply Gaussian blur or unsharp mask to the entire image) creates a full copy of your image at its original size.

My personal choice is to assign about 65% of my RAM to Photoshop, and let Photoshop figure out the scratch disk itself. Note: I never subscribed to this theory to begin with. In Photoshop CS2, you can use the states in your history palette to help you determine how much scratch disk space you need.

With changes in Photoshop and its memory management, the formula used in the past (that is, 3-5 times the size of your average image) no longer provides an accurate estimate of how much scratch disk Photoshop needs.
