Hi all, My name is Yan. I am running a study to understand why some photos look better (or worse) than other photos. My current focus is on portraiture photos. For example, here are two pictures of myself. In the HIT, you will need to rate both photos, and write down one main reason why you prefer one photo over the other. The HIT is fun and quick. Our pilot test shows that it takes about 45 seconds to finish one HIT. We pay $0.08 for each HIT. In total, there are 40 HITs. If you finish all 40, we will give $1 bonus. The link to the HITs is: https://www.mturk.com/mturk/preview?groupId=2E3CT2D5NQYN8NKAEX753YMOL2Z48Q You can also search "photo aesthetic quality comparison" to find the HITs. Thank you so much for your help! Best, Yan
