2GB intern memory – Win2KJaap,
Jaap
My aplogies. Since replying I have checked the cache level on three different PC’s and it was set to 6 on them all, even though the individual installed memory was 256MB, 512MB and 1GB. So it looks like memory doesn’t come into it. What is yours set to?
From the help files
"Cache Level Shows the current image cache used to create the histogram. When the cache level is higher than 1, the histogram is displayed faster because it is derived from a representative sampling of pixels in the
(based on the magnification). The original image is cache level 1. At each level above level 1, four adjacent pixels are averaged to arrive at asingle
pixel value. So, each level is half the dimensions (has 1/4 the number of pixels) of the one below. When Photoshop needs to do a quickapproximation,
it can use one of the upper levels. Click the Uncached Refresh button to redraw the histogram using the actual image pixels."
