There is a noticeable difference when I apply the lens correction so I know that the profile applied does something. Export to APG as 8bit TIFF. Camera is D800E
Clearly vignetting. F:5 isn´t sufficient for avoiding vignetting on a 70-200mm zoom.
Put away the filter.
I strongly suggest to use CaptureOne Pro and have all the shots analyzed. I also suggest to use C1´s most geniously LCC option: you need to shoot a frame by holding a piece *white* plexiglass directly on the lens after you took the series.
In C1 LCC analyzes this frame regarding the lens´ ColorCastCorrection - which includes also vignetting
and dust. Then you have a perfect *LensCast+vignetting Correction* profile for *this lens* regarding *this particuar shoot*.
I the workflow C1 uses this data to optimize the outcoming from the RAW converting.
It´s a tool i´d NEVER would stop using when it comes to really elaborated shoots.
Take care to have a perfectly clean disk of white Plexiglass. I have a 10x10cm
piece and always keep it protected when it´s not i use.
Thanks once again for your help.
