D800 .JPG compression vs RAW/NEF (vs Vignette control ON ?)
Once upon a time, on a very foggy winter day I shot a picture with a D800 plus 70-200 mm VR II f/2.8 to the far distant lake bridge (small insert 100% cropped). Once home I worked on brightness and contrast and … the JPG version (set to maximum quality) showed its weakness. Or was it the Vignette control ON? I doubt it works on the centre of the picture. So, keep in mind the power of RAW files in difficult light conditions.
