in your opinion, is Lens Correction in LR worth it to use or does it cause too much harm to my prints?
Even when using a well corrected 50mm lens, i still like to use Lens Correction as it seems too totally flatten my image but I am sure if I am damaging my print in any way.
It’s worth if you shoot very technically and you need to remove certain defects. I shoot with 50 year old lenses quite often because I like the defects. Most of my lenses actually do vignette - so I do not use vignetting in LR.
If you do not like some slight curvature, etc and you feel your images would be better with the correction - then correct. It does not damage the print.
