yup, you've got the right of it. and not only that, but different folks are using different programs and some use more than one. flora and yourself are using PS where i'm using PSP. add in that there are not only different programs but different versions and you've got various folks using the same tools but with slightly different versions at times, or one version will have this or that tool where another version wont have them. it can get quite confusing at times.
the main thing, though, is learn the tools you have and practice, practice, practice
oh, and nice job, flora. some day i'll get there
