How important is the lens correction in photo editing?

 

Here I have 2 of made with pictures I have darkened a bit so you can see better of what I write here. To preserve the identity of the lady, I have made the face unrecognizable. But that does not bother here. Test objective here was the Tamron 18-270 F3.5-6.3 DI II VC PZD.

Here is clearly seen from the center of the image as the light intensity of the lens approximately from the red lines and before falling to the outside. The red lines do not have the claim to be exactly right they should only clarify in which area this begins approximately for better perception. I hope you can recognize that. Nice to see that also at the rear blue pool edge.

Here the effect has disappeared, the picture now has a uniform brightness up to the edges. These bugs can be fixed with Camera Raw. In the program are from x manufacturers and x lens correction data implemented. If the data is not available, you can do it yourself.

 

Here are two more pictures next to each other

The test lens here was the Nikon Nikkor AF-S DX VR 18-200mm F / 3.5-5.6G IF-ED

Another lens the same effect just not as violent as the Tamron.
I hope the tip has brought you a bit further on the way to even better pictures.
