Now and again, writes Nick Melidonis, it’s good to go back to basics and review how we approach our workflow.

"I’m currently working on a series of architectural images shot in large Asian cities. In the years BD (Before Digital), photographers using film didn’t have a lot of options when dealing with converging verticals. Converging verticals are the convergent lines or keystoning we are all familiar with, which occurs when pointing our cameras up at tall buildings or structures. Similarly, there weren’t many options for dealing with the distortions created when using very wide-angle lenses (volume anamorphosis).

"Converging verticals can be removed by having the plane of the camera lens parallel with the plane of the building you are shooting. If this does not produce the image you want or is difficult, then SLR users can use perspective correction or tilt/shift lenses and move the front of the lens up or down or sideways. Film users could also adjust the lens plane by using the front standard on large format cameras (not many of those about). The latter corrections are still used by some architectural photographers today.

"Anamorphosis with film cameras was hard to eliminate, especially when the photographer had to get very close to the subject with wide-angle lenses due to a lack of space. Fortunately, the solutions to perspective correction have become much easier with the use of digital software and this article will cover lens corrections in Lightroom, Photoshop and DxO Optics’ ViewPoint Software."
