Working With Filters And Large Images

When applying filters to high-resolution images, Photoshop may slow down and take some time to complete the filter, especially if you’re using a memory-intensive filter. If you’re testing filters, this could become a problem since you’ll have to wait every time you make an adjustment.

To speed up your computer’s performance, you can create a selection and then apply the filter to that smaller portion. When you find the filter and settings that you like, deselect the selection and apply the filter to the entire image.
