Fixing distortion in Dark room?
« on: September 09, 2012, 06:51:39 AM »
i was wondering how to go about doing this.
i found this on wikipedia but since im new to printing i dont get it at all

http://en.wikipedia.org/wiki/Perspective_control#Perspective_control_in_the_darkroom

i have a lomo l-ca with the wide angle attachment but it distorts like crazy. i could just scan it and then fix it in lightroom but i was wondering if any of you have done it the "old fashioned" way.

Have a look at this diagram which shows what the Wiki article is descibing.

But, if the LCA distortion is fisheye type distortion then this won't help.

Both barrel and pin-cushion distortion are pretty much impossible to correct in the darkroom.
The only way would be to have a lens that distorts the opposite way.
But fixing distortion that's related to perspective works fairly well.

But personally, I tend to leave things like they are and take distortion as a part of the image's look.
