15 Minutes in the Morning:
The upsides are many. Lots of wondrous shots from places I’ve never heard of. Lots of “how’d they even get that shot?!” photos of animals. Despite that I don’t use the site like I used to (and none of my friends do either), Flickr is a worldwide phenomena and still a place where very good photographers share their best works. And the Explore page changes every single day, replaced by another several dozen amazing new photos.
I tell all my students to check out the photographs on Flickr’s Explore page, either to see how others shot the same thing or to use it as a way to train their eye for composition and other elements.
