Many lab services offer a standard set of prints that are designed to "impress," but they have little to do with the type of work you would do.
While we could send you a "generic" pack of sample photos that would be
certain to look great, we normally suggest that you use a representation
of your own work - your images. You can order these at cost (wholesale) for samples. In that
way, you can see that your settings on YOUR images works well with our
processing/printing.
Many of our users felt that by getting samples in this manner, that
their work was fairly and accurately represented in the actual print
process. You can upload some of your best shots into a sample/portfolio
gallery and purchase any of our products or prints at cost. In addition to being able to fairly judge what YOUR OWN images will look like, it will
allow you to become familiar with our workflow, as well.
Of course, you can do this during our free 15-day trial period. During
that period of time, we offer you a fully-functioning site to check out
and use as you see fit.
