If you love an image (whether it's yours or someone else's) and want to make sure others get a chance to see it, you can “feature” it by choosing the “Spotlight” button.
When an image is Spotlighted, it receives enhanced visibility in premium spots throughout the site. Spotlighted images are rotated through these higher-visibility positions to ensure the best opportunity for the images to be seen by JPG users.
If you see a great photo that would make a perfect entry for one of our Shoot Out photo contests but it was uploaded by another user, now you can enter that photo in the contest and, if it wins, you get to share in the contest winnings.
Like a photo editor, if you've got an eye for great work, find it and submit it to a contest. If it wins, since you staked the entry fee, you'll take home part of the prize (the rest, of course, goes to the member who shot the image).
Collections are a JPG+ feature. You must be a JPG+ member to create new collections and to add photos to collections.

ATOPTICS "The complexity arises from the shape of the water surface. Ordinary mirrors are flat, convex or concave. They produce simple and single images. They have a fixed curvature.
In contrast, wavy water even at a single 'frozen' instant changes in its curvature from point to point along its surface. Its troughs are certainly concave at their deepest but the curvature decreases towards the crests passing through an inflection point and then becoming convex. And that is only in one dimension, the curvature alters differently in others."
