DxO Optics Pro is a program designed to correct the distortions, aberrations and other faults of common camera/lens combinations using customised correction ‘modules’.
The K-7 is Pentax’s top digital SLR and is aimed at enthusiasts and professionals. The built-in anti-shake, distortion correction and aberration removal are excellent, but Pentax’s lens range is patchy.
This is where the sides of tall buildings converge, and it’s a big problem for architectural photographers who need to show buildings with their correct proportions and shapes. It’s not ideal for the rest of us, either, because it can [...]
This is a fixed focal length lens, rather than a zoom. Zooms have taken over because they are more convenient, but prime lenses are more compact and offer better performance, with little or no distortion and, sometimes, better contrast and [...]
Fixing converging verticals in buildings, for example. This can be achieved by using a special perspective correction (PC) lens or by using software. There are two ways to correct converging verticals or other perspective faults in Photoshop. You can use the [...]
A fisheye is an extreme wideangle lens that no longer attempts to render straight lines as straight. Instead, they appear as curves which are more pronounced away from the centre of the frame. This distortion effect means that fisheyes are [...]
Distortion is where straight lines become curves or appear to converge, and it comes in two types: perspective distortion and lens distortion. Perspective distortion is natural and inevitable. It’s when the tops of tall buildings appear to converge or railway lines [...]
