oops, Chas, looks like I kind of messed up things when I deleted my previous post concerning curves.
Thanks for your info about smart curves. I've been thinking about installing it.
edit for my previous/deleted post:
Thanks for the url to the site, Tinahttp://www.mehdiplugins.com/english/kaleidoscope.htm
Just for the heck of it, I extracted & installed the filter into my elements6 plugins/filters folder (I didn't want to chance messing up my CS3). The plugin file is 515 kb compared to the 25mb Williams template file. The plugin caused no problems & works great with many options --- really fun to use.
I'm sure that the Williams templates produce beautiful results, but 25 mb seems high for something which will be used only occasionally.
btw, there are some pretty interesting free plugins at the same site.
