Perspective Correction for Analog and Digital Photography

The equalizing of converging lines or of unfavorable perspective due to a camera location made necessary by obstacles, reflections or danger, e..g.. traffic, is not only interesting for conventional analog photography, but also for digital photography when higher quality demands are made.. While digi- tal images or digitized (scanned) analog images can be equalized on the computer using image editing software such as Photoshop, this is, however, associated with substantial degrading: If the rectangular image is distorted in the manner of a trapezoid for the parallel alignment of the converging lines, the interpolation (recalculation of the pixels) required for this reduc-

PC-SUPER-ANGULON 28 mm f/2.8 specifications

The Schneider Optics PC-Super-Angulon 28 mm f/2.8 is a remarkable wide-angle lens designed specifically for large format cameras, making it a favorite among landscape and architectural photographers. Renowned for its exceptional sharpness and striking image quality, this lens embodies the precision and craftsmanship associated with Schneider optics.

One of the standout features of the PC-Super-Angulon is its perspective control capabilities. The tilt and shift function enables photographers to manipulate the plane of focus and alter perspective, effectively reducing distortion in architectural photography. With a tilt of ±8° and a shift of ±12 mm, users can achieve remarkable control over their imagery, allowing for the creation of natural-looking images without the typical converging lines seen when photographing tall structures. This feature is particularly advantageous in minimizing the effects of perspective distortion and maximizing depth of field.

The lens offers a fast maximum aperture of f/2.8, providing excellent low-light performance and allowing for more creative depth of field control. The optical design comprises high-quality glass elements that ensure outstanding sharpness across the entire frame while delivering rich color rendition and contrast. The lens features a multi-coating technology that significantly reduces flare and ghosting, making it ideal for shooting in challenging lighting conditions.

Measuring 80 mm in diameter, the PC-Super-Angulon is compact for its class, making it relatively easy to transport while offering superb performance. Its robust construction ensures durability, which is essential for photographers working in various environmental conditions. The lens is compatible with a range of large format camera systems, emphasizing its versatility.

Additionally, the Schneider Optics PC-Super-Angulon employs a circular diaphragm, which enhances bokeh quality and contributes to the aesthetic appeal of out-of-focus areas. This characteristic is essential for achieving beautiful, soft backgrounds in portrait photography, setting it apart from traditional wide-angle lenses.

In summary, the Schneider Optics PC-Super-Angulon 28 mm f/2.8 distinguishes itself through its combination of advanced perspective control, exceptional optical performance, and a user-friendly design tailored for large format photography. Whether capturing sweeping landscapes or intricate architectural details, this lens delivers an unparalleled photographic experience, making it a valuable addition to any serious photographer's toolkit.
