Make Impossible Real Estate Pictures Possible - The Secret Revealed Part 3: In most real estate pictures a single shot almost always completely fails to capture the wide field of view that the human eye sees. In this article we’ll detail how we photograph overlapping images and then use special software to combine them into one photos.
Taking The Shots
Essentially you want to capture a series of images around a single point of rotation, so a tripod is ideal. Fortunately it isn’t essential for most images so long as you keep the camera as level as possible and keep the movement as you rotate to a minimum.
You want a good area of overlap on each shot, preferably a third or more. It’s much better to take too many shots rather than too few.
Taking multiple shots also has the major advantage that it helps cut down distortion. If you think about looking at a fence, at the center of your vision the slats of the fence produce regular rectangles, but on either side perspective turns these rectangles into trapezia with each fence post progressively smaller into the distance. Trying to match these from one photograph to another would be impossible, so you want to be able to work with just the head-on central sections. If your camera doesn’t have a fixed lens it’s also better to, if necessary step back, and zoom in and take more images more flat on.
Closely spaced photographs also help cut down on the widely varying results produced by automatic exposure cameras. Auto exposure compensates for different lighting conditions by adjusting the tonal range between shadows and highlights. This produces the best results for each separate picture but means that the colors of one shot can be completely different to the next.
Software
Once you have your series of overlapping images you will transfer then to your PC and then use software that will combine (stitch) your overlapping images into one image.
