Standard perspective when standing on the ground and the lens horizontal. Rise/Fall Trees in Spring Snowstorm Auburn, Ohio. It also eliminates throwing away pixels during the warping process. For me, that is invaluable and something I have come to rely on and expect in my fieldwork. Alpa stc system lens software#But, unless you have and employ all those software tools on location, using a technical camera is the only way I know of to see that framed image in the field with the finished perspective. You can use software to create essentially the same image without rise/fall by transforming the image later in one of the many programs we have at our fingertips. It’s not the “right” way or a better way just a different way that results in a different perspective. That is completely foreign to most DSLR users. I tend to set up the camera oriented perpendicular to the ground, then use rise fall for framing. The simplest example of this is using rise/fall. The above movements play a key role not only in field workflow, but also in how we see. This is not just a feature, but for most of us it is the reason for shooting with technical cameras. Tilt: Apply lens tilt to adjust the plane of focus angle, which creates a depth of field wedge that keeps subjects at various distances from the sensor plane in sharp focus.It also allows you to shift the back in its portrait dimension in order to make use of the wider lens image circles, which increases the angle of view. This is a simple and reliable way to create a panorama, and is something I do very frequently. There are applications for perspective control, but most of the time this is done to stitch two images together. Shifting Left/Right: Usually accomplished by sliding the back left/right.In general, this is done to keep the back and lens perpendicular to the ground, but there are many other applications. Rise/fall: shifting the lens and/or the backup/down to frame the scene without tilting the camera.There are three movement applications frequently used with technical cameras: Rodenstock f/4 40mm HR-W.Įarly in the first article, I mentioned camera movements:Ī primary benefit of using a technical camera is to apply movements and utilize the larger image circle associated with most of the dedicated lenses from Rodenstock and Schneider. Lowering the back (or raising the lens) raises the frame and captures more sky / less ground. ![]() Back was lowered to position the trees vertically in the frame without tilting the camera up. ![]()
