I'm curious if there are any good methods for correcting lens distortion. Like can I print a poster, take a photo and use that to create a correction map?

- yboris 5y agoIf I remember right, the professional software "DXO Optics Pro" was doing this. Since then, they bundled that functionality into their newer products: https://www.dxo.com/technology/lens-distortions/ https://www.dxo.com/technology/lens-distortions/ The way it works, iirc, is you can choose the model of your lens and the software fixes things. Works for professional lenses, unsure about others.
