I have a large number of photos (aerial photos) shot with a fixed-aperture wide-angle lens. The all have vignetting in the outer portions of the images, with the corners of course being especially dark.
I’m trying to figure out a way to do a batch process of removing/lessening that vignetting effect.
I’m curious if anybody Dopers have had to deal with this, and what process you may have used?
Photoshop can do it.
Yes, you can do it in Photoshop; there is actually a vignetting tool.
You can get rid of it in Lightroom as well. Look for the Lens Correction setting.
Another option is to just crop it out.
Can’t crop it, the data is there, just needs basically a brightness enhance. And I need to to it on 500+ images per project.
I’m trying to figure out Hugin right now, to see if I can do something with that.
Lightroom can handle that easily, assuming the amount of correction is similar across the batch.
Do you have an idea what caused the vignetting? Thinking about how to prevent it in the future.
Likely causes are stacked filters, use of lens hood, super wide angle lens and/or wide open aperture.
Isn’t it expensive to prevent it outright? Once you set it up as part of your workflow, it just takes a few seconds to process it. Simple fix vs spending thousands more for higher quality lenses and such…
And if it’s with a known camera-lens combination in its database, it’ll set the vignette amount automatically and correct for distortion automatically (under Lens Correction > Enable Profile Correction.) Judging by the description of the lens, it sounds like it may be a specialized lens, but, regardless, there’s easy sliders you can use to manipulate it manually.
