What does rectified photography specifically aim to eliminate?

Rectified photography aims specifically to eliminate optical distortions that occur when capturing images of buildings or large objects. This photographic technique involves correcting the perspective of the image to ensure that the lines of the structure appear straight and true, rather than skewed or bent, as they would in a standard photograph. By doing this, rectified photography provides a more accurate representation of the scale and proportion of the elements being photographed, which is particularly valuable in architecture and construction.

In this method, the camera is positioned at a right angle to the subject, and post-processing techniques can further adjust the image to ensure that lines which should be parallel, such as the edges of a building, appear so in the photograph. This accuracy helps in creating clear visual documentation that can be used for analysis, design, or presentation purposes.
