I just went thru some of the pages. I don't remember who asked about removing stretch marks, nor can I find what page it's on now. I don't have photoshop elements, but do have photoshop CS4. To get rid of stretch marks, I use a combination of spot healing and the patch tool. I don't use contrast or bright lighting, as you lose a lot of details, and I like skin to look like skin. There is also an AMAZING add on called Portraiture. It's I think like $200, but it gives you that magazine cover quality skin, while still maintaining the texture of skin (not that plastic Barbie doll look).
About the copyright of the photo. The copyright (owner) of the photo belongs to the photographer, whether or not it's been edited. I know this from when I used to model. Even though it's a pic of me, it doesn't "belong" to me. My husband is a graphic designer, and some photographers would hire him to edit my photos. So even though I'm in the pic, and my husband edited the pic, the owner of the pic was still the photographer. I would always have permission from the photographer to post the pics, and my husband would have permission to use the pics in his portfolio. Can be kind of silly at times, especially if I had wanted to have a pic printed of ME, and I couldn't get it printed without a release from the photographer. Even if it's a photo of ME, edited by ME (like my avatar), still nada without a release.
Not that I think that any of the ladies that you've done work for would complain about the legalities of copyright, I just think it's interesting how it works.
What a fun service you've offered
I always wish I had done maternity pics with my two other girls.
