1. RF stock is only part of my photography business and uploading to many sites and tracking them all is VERY time consuming because of the difference in reviewing standards, types of images that are accepted, model release requirements, etc.
2. Protecting the use of my images is IMPOSSIBLE if I have them strewn all over the web. With one location to purchase my images, I am enabling one agency to protect my images. By uploading to more than one site, none of the agencies really have the ability to protect my images at all.
3. To maximize the amount of money I make on each individual sale.
I know this decision isn't for everyone and most of the top RF stock professionals are not exclusive with anyone, but I will never have 10,000 images in my portfolio. I will re-evauate this decision if that DOES ever happen. For now, I started here at DT and I think it is time for me to come back here and only here.
