Rather than do this, it would be nice to add some adjustable parameters to the lensfun vignetting correction, similar to how the TCA correction can be overriden with manual controls. It's better to do this correction earlier in the chain anyway. >From what I understand, there's some discussion about the re-implementation of >the lens correction module in the future, pending addition of perspective >correction to lensfun.
