I notice and odd statement on their guidelines. It reads:
"The photographs can be either prints, Polaroids or transparencies and show a variety of poses, including full figure and face shots. We do not accept these photos in any computer form nor do we visit websites. Please do not send us CDs, discs, e-mails or undeveloped film since we will be unable to review your submission with these contents."
Note they indicate that they do not accept images in electronic format (such as JPG, etc). What is odd about this is that include a link in the same article to "How to photograph your girl freind guide" and the submission rules there state:
"Scan in your Polaroids and send them to us electronically via email -- preferably in high-quality JPEG format -- to firstname.lastname@example.org
So one wonders what they really want. It seems to me that a JPG produced directly from a dSLR would be much easier for them to use than a slide or print or a Polaroid. I wonder if the material is somewhat out of date?
