Some scenes can’t be contained in the 2×3 box. There are ways to cope with this, we could crop the image, eliminating the parts we don’t want to appear in the final product. Depending on how much we need to crop out, we might require a really good source image to leave enough pixels to make the image presentable.
Some scenes can’t be captured with the widest lens in your bag. In these cases, we can opt to make a quilt by stitching several images together into a panorama. This allows us to make a large base image which can be enlarged easily. Depending on the number of source images, a pano stitch can take a loooooooong time to render.
The morning after. A single shot, cropped to increase the illusion of width. Pixel count dropped from 24mp to 15mp, still enough to make a large print 30 inches long.
This is one shot with a wide angle lens, cropped to emphasis the expanse of the Tetons. There are insufficient pixels to allow for a large print. Pixel count dropped from 24mp to 7mp. Zooming in on the image will not reveal great detail.
Virtually the same scene but composed of 9 images merged in a panorama. The resulting base image increased to 38.5mp, enough to make a large print. The higher pixel count also brings more detail to the image.
Sometimes there is no way to convey the grandeur or expanse of a scene like Bryce Canyon with a single shot, no matter what lens is used. This image is 9 horizontal shots taken with a 70-200mm lens. The amount of overlap dictates the number of shots required. At 73.5mp, the image has lots of detail and can survive well as a very large print.
This image of Lunenburg, NS was made by stitching 26 portrait images together. The resulting image is 99.6mp and was printed as a set of three images each 36 inches long which were then hung as a triptych.
Yes, we can go vertical with our panoramas. This picture of the church in Rincon de Guayabitos, Mexico was made from 5 portrait images for a total of 47mp.
