You will also note differing amount of barrel distortion and or pincushion distortion, with zoom lenses, at different focal lengths.
In the film days, I had one of the very first commercial zoom lenses, a 43-86 mm Nikkor. That lens was pronounced barrel at wide, almost free of distortion at normal, and pronounced pincushion at telephoto!. That, and there was no good way to correct it using analog stuff, like an enlarger...
Hi Askewed View Photographic Arts photos by Keith A. Russell ! You may try controlling the barrel distortion by increasing the focal length. I'd take several shots of the same subject with a different focal lengths and looked at the result. The chances are the distortion get significantly diminished (if not disappear all together) when you zoom in. In addition to the lens distortion, when you position your camera not perpendicularly to the subject you also create a distortion. Again, try shooting the same subject from the higher, lower and perpendicular positions! Just my "handful of cents" ;)
Unwanted distortion is pretty easily dealt with.. Personally I feel like ultra wides should have some barrel distortion... Corrected it just looks weird..
Thanks for your input Kevin Vincent. It depends on what you're looking for in the final outcome. For certain shots, some distortion can be an enhancement stylistically. But if you're looking for more polished work, then it should be corrected.

The focal length this was taken at was 20mm, the same with the other shot. As Jamie Hyneman would say, "There's your problem."

ReplyDeleteMichael Mossiagin, more like a handful of gold. I'll surely have experiment with focal lengths. I think that might be the trick.
