In my last post, I was talking about flat field correction, a technique that allows to fix lens vignetting and associated lens+sensor color cast.

Here's a first result 🙂

This is the same picture of an uniform white reference, with contrast +100 in Lighroom to emphasis the difference:

– Without DNG correction
– Without DNG correction but with Lighroom built-in Lens Vignetting tool adjusted to best settings possible
– With DNG flat-field correction defined in the DNG file itself: to the user, it's like vignetting or color cast were never here!

And.. back to code 😉
