I do all sorts of things with my images, really. A good number of the photos I take are aimed for projects which will become either thematic books or online presentations (the latter especially for things like science talks and newsletters associated with my job). Travel pics are sorted and worked into travel books, mostly for my own pleasure. I also keep a yearly, week-by-week photo journal. I've found that is a terrific way to both self-evaluate and share ideas on lighting and so forth with others. It also serves as a great index for my images as well. Finally, I maintain a website with images I feel like sharing with the world at large.
Over the past few years, I've begun to make single prints of more photos for framing (I stopped completely in 2002 and didn't print a single photo for 5 years). The only problem with prints is a lack of wall space!
