I wouldn’t call myself a “Professional” Photographer. I do well enough to have a few people pay me for the service. (Which, technically, is the definition)
I have found a website called “Pixoto” that allows you to post your photos and have other professionals rate them in “Duals” (your photo against another in a similar category). Every time you vote, you get a credit. You use the credits to post and give “boosts” (more duals) to the images you feel deserve more of a shot. As a brass ring for you to reach for, they have Daily, Weekly, Monthly and Yearly awards that may be had as Best, Top 5, Top 10, Top 5%, Top 10% and Top 20%.
You don’t even need a high end camera to “compete” on this site. A photo I took of my Daughter with my phone just won a yearly award for the “mobile” category!
If you’re a pro, this is a great way to be noticed. They even have a marketplace option that you can sell your images through them. If you’re not a pro, it’s fun to see where your stuff rates against “the masters”. For everybody, it’s a wonderful place to get inspired for your next shoot!
It’s free, it’s fun, it’s valuable!
