Quality of the photo. You know, exposure, framing, even composition. Clarity. The things that make a photograph, a photograph and enjoyable to view. For instance for this discussion we will use two images. The "afghan girl" of national geographic fame. As well as an image of Joel Sartore, the bear standing in the stream catching a jumping fish mid air. Both of those images have composition, proper framing, proper exposure. They work and people love them. They are images the photographers are well and truly proud of. But as someone who wants to be good at photographer, its easy to look at current fad movements. When it comes to fad movements the only thing that pops up is Lomography and its stupidity. To them, great images, are what actual photographers dread taking. Just crap, that we all study proper photo taking to AVOID> But because the Lomo mindset is that ANY bad photo is a GOOD photo,,,, These people are rewarded with internet fame for taking a photo of a teddy bear, that when developed. Could be a photograph of a flour tortilla, or the start ship enterprise in a snow storm.
