In this study, in each trial you will be shown three images. The image on the top is the reference image and the other two are comparison images. You are asked to decide which comparison image is more similar to the reference image, the left one or the right one. Choose by clicking on an image. You can change the exposure of an image by using the slider on top of each image.

The experiment should take about 20 minutes at most. Thank you for your contribution. Please do not use Refresh, Back, and Forward buttons of your browser during the experiment. Mobile devices are not suitable for this experiment.
