I shoot thousands of frames of film every year but I post very, very little. Part of the problem is that I am very, very critical of my own work. I have this mental block against posting something I am not personally happy with.
Second, I am usually happier with my printed work (digital or analog) while that same picture displayed on a monitor does not look the same. Most of my favorite work has been printed and I have a very tough time posting the digital version while the print is so much better to my eye.
Third, I find that I am more likely to post photos that were taken digitally than I am those that were taken with film. And those I do post are rarely printed after I post them. I think that I have this thought in the back of my mind that digital work is less important, though that idea has been changing quickly since I bought the DP2M. Some of the photos out of that camera are beginning to reform my opinion of digital. I just printed one of my photos from that camera on Red River's Pearl paper and I am stunned by the color, depth, clarity and detail in that print.
