Thank you all for participating! The winner of this contest is user "Barazesh", congratulations!
We've seen a lot of great entries. The 2nd came "KradellArt", and in 3rd "armansim07". The difference in performance between the contestants is small but clear. We evaluated the accuracy and correlation of the entries to the mean opinions of 15 other professional photographers and designers.
The top 20+ participants will now be accepted to participate in the main project (4 and 5 stars): https://www.freelancer.com/projects/photography/Rate-the-quality-images-academic/
The top 10 participants (5 stars) can also place their bid here:
This is a slightly different task, which still requires a keen eye for quality degradations. We only need 5 participants in this project.
Many of you should have already received an invitation.
