It may not be practical for everyone, but Bryan O'Neil Hughes, Director of Product Management and Outreach for Adobe, suggests finding a way to stabilize your camera, even if you're just snapping a quick shot. That means setting up a tripod and blocking the wind if you can.
"If possible, trigger the shutter remotely or with self-timer to minimize vibration," he says.
4. Get the Best File Possible
"The better the file, the better your experience editing," says O'Neil Hughes. If there's any chance you'll be editing the file in some way, get the highest resolution photo your camera will take. With an SLR, shoot raw. If you're using an iPhone or another smartphone, shoot in HDR.
Additionally, if you're using a smartphone, don't zoom in. That's going to reduce the quality of your photo. You can always crop the image afterward.
