Quick Tip to Improve Drop Shadows
Lately, I've been doing a lot of deep drop shadows, and I was having the issue of a limitation on the gaussian blur. In the images below, one has a smooth gradient drop shadow, but in the other the drop shadow is cut off. I found that there was a simple fix. All you have to do is go to Effect> Document Raster Effect Settings, and under 'Add' increase the number (I went from 36 px to 80 px). Easy fix!
