Minimum filter use a problem.
I am having a problem using the minimum filter in Photoshop to reduce stars in my recent images. The min pixel size for this filter is 1 Pixel. Using this setting removes almost all stars from the image and leaves it quite pixelated.
I suspect it has something to do with image scale or resolution. Is there anything I can do?
