This might sound a bit odd, but the "Simple Trace" settings in CS5 were perfect for tracing my artwork for a graphic novel I'm working on. I upgraded to CS6 earlier this year but due to other issues had to take a break working on the graphic novel.
I came back today and drew the source images as I had before (in Paint Tool SAI using only black pen brush for a clean line) and then exported this to a PNG file which I then imported into Illustrator. I assumed that Default in CS6 was the same as Simple Trace in CS5, but it gives far fewer details than Simple Trace does! Is there anyway I get get the Simple Trace settings back?
