Modern digital camer as do a lot of automatic white-balancing, aperture adjustment, focus adjustment, and shutter speed changes when you take a photo. While this can be a helpful feature, if you snap a bunch of photos to stitch together you can end up with an in consistent image due to differing exposures in each shot.
“Set your camera to manual focus and use aperture priority,” professional architectural photographer Barry Grossman says. “This way, your series of images will stitch much more effectively, with less variances that may degrade the final product.”
Take panorama photos from left toright. Overlap about a third of each image between the shots, just to play it safe. This gives you some extra room to work with when you’re editing your photos.
