Some
filters and effects are memory intensive, especially when applied
to high-resolution images. You can use these techniques to improve
performance:
Try filters and settings on a small
selected area of the image.
Try filters and settings on a smaller, resized copy of
your image. When you’re satisfied with the results, apply the filter
with the same settings to your original image.
Free up memory before running the filter or effect by
clearing the clipboard, the undo history, or both. Choose Edit >
Clear >
[command]
.
Exit from other applications to make more memory available.
Adjust filter settings to make memory-intensive filters
less complex. Memory-intensive filters include Lighting Effects,
Cutout, Stained Glass, Chrome, Ripple, Spatter, Sprayed Strokes,
and Glass. (For example, to reduce the complexity of the Stained
Glass filter, increase cell size. To reduce the complexity of the Cutout
filter, increase Edge Simplicity, decrease Edge Fidelity, or both.)
