The more visual clues you feed to the Photoshop algorithms, the better and cleaner your results will be. Photoshop needs this overlap image area to identify and merge visual elements that are common between adjacent images. When capturing the individual frames, it’s extremely important to leave about 20% image overlap between each frame. Lenses in the 24 to 28mm range require about five still images to create a 180° panorama, and seven to eight still images are needed to create the same 180° panorama image when using a 50mm lens. In the case of 14 to 18mm ultra-wide-angle lenses on a full-frame camera, it’s possible to create a 180° panorama in three frames. The number of pictures required to produce a merged panorama photograph depends on two components: how wide you want the horizontal plane to be, and the focal length of your lens. Level images make for better panoramas, even when you can’t see the horizon line in the picture. If your camera has a built-in electronic leveling feature, this is the time to use it, regardless of whether you are shooting handheld or mounted on a tripod. The three top photographs were taken with a 15mm lens, merged together into a panorama, and cropped to eliminate distracting visual elements and optical distortions (bottom photograph). This article is for those who-like me (thanks, Sony!)-do not have a panorama mode in their camera and require some help from Photoshop to create panoramic images. For the most part, these in-camera panorama modes work quite well. These images are processed and merged in-camera into a single, wide-field panoramic photograph. Today, many consumer digital cameras have a Panorama mode, which captures 50 or more consecutive stills as you slowly pan your camera from left to right, or vice versa. Film for these cameras is typically produced in small batches once or twice a year, by companies that include Ilford. Wide-field panorama field cameras that recorded panoramic images on large sheets of cut film are still produced by small custom camera shops. The first is with a wide-field camera, which in the film days were typically medium-format cameras that captured 6 x 12cm or 6 x 17cm photographs on 120 and 220 film. Panoramic photographs can be captured in several ways. Rows of sunflowers captured in a series of five stills using a 25mm lens on a full-frame camera and merged into a single panorama in Photoshop How Are Panoramas Created? This two-part story became a three-part story when I had to turn to Adobe Photoshop for merging my 2:3 images into wider-field panoramic photographs. The a7R III doesn’t, which is why my original plan to create panoramas with varying focal length lenses by using the in-camera shooting mode suddenly morphed into something different, and I had to turn to Adobe Photoshop to merge my 2:3 images into wider-field panoramic photographs. My a7S, a7R, and a7R II each had a Panorama mode. I have long been a fan of panorama imaging, you can imagine my surprise when I realized my Sony a7R III-the fourth Sony A7-series camera I’ve owned-does not have a Panorama mode. Do it right and you get a terrific panoramic image of up to 360 degrees, depending on how you set your camera. If your camera is on a tripod, so much the better. Move slowly, evenly, and keep your camera level with the horizon. Simply set the camera to Panorama mode, frame your shot, and follow the panning instructions in your viewfinder. Panoramas are visually interesting, and that’s why Panorama modes can be found on many consumer cameras.
