It is important to pick the right slide. Portraits just do not work well. Some report mottle. Some report a cyan Dmin. It varies. I generally get good results with landscapes and flowers among others. I have heard more problems with CA than with Endura. I use Dektol and RA-RT developer replenisher. Others report poor results with these and use other first developers.
I use a heavy magenta filter pack, as my prints come out very much off color.
