Tilt & Shift To Boost Your Megapixels
While tilt-shift lenses can be used for both practical and extreme purposes, they also can be utilized to increase your image file size and creativity in unexpected ways
Why not create your own focal length? This concept rattled around in my head for some time after going digital. Then again, many things rattled around in my head after I went digital. But one concept that rattled louder than others was how to utilize a moving lens mounted on a camera body to achieve multiple formats and compositions. With this in mind, I started using a Canon tilt-shift lens and began combining two offset digital files of the same scene. I began creating new compositions and aspect ratios and also increased the file size of my images all without the use of panoramic equipment.
One of the most important parts of the creative process in landscape photography is finding the light, followed closely by subject and composition. The limitations of working with certain focal lengths also interrupt the creative process by confining the composition. When I mounted my digital camera and tilt-shift lens on a Really Right Stuff panoramic rig, however, the visual possibilities became endless.
As my digital skills advanced, I began to realize that there was no reason to be confined to one digital file taken with one focal length. I now could work with a system that helped me achieve what I aptly call "building a composition." By combining multiple images taken with just enough overlap to stitch together in Photoshop, I could include anything in my desired field of view, both vertically and horizontally.
The first and most efficient step in this process is to use a tilt-shift lens on just about any digital SLR body mounted on a tripod. Once a scene is located, my first decision is to mount the camera body in a vertical or horizontal position. I do this with the aid of a Really Right Stuff "L" bracket and ballhead on my tripod.
