RFFers,

I am trying to lick this vignetting problem with the 15mm f4.5 Heliar and am not having a whole lot of luck without introducing noise (sometime substantial) in the corners.

What workflow are you using to overcome this falloff? I use CS2 and would like to keep it as my only "processor" for both my DSLR and the R-D1s. But I am open to any successful strategies with any of the RAW converters.

Any help is appreciated, thanks in advance,

I use the Epson PhotoRAW software.

I tend NOT to use the 15mm setting but the settings for 2-3-4 focal lengths longer, sometimes settling for the settings for 50mm. This reduces a certain amount of vignetting but more importantly prevents corners that seem too bleached out and noisy.

Then again, I often just let the vignetting be. It can really add something to a shot.

Truth be told, I don't use the 15/4.5 very often. While I very much enjoy the 25mm on my Bessa L or R, I can't get used to the 15mm on the R-D1.
 
Agree with RML, I find the 15mm vignet setting of PhotoRaw too strict. If other adjustments are included (curves, color filter in B&W, EV correction) the noise gets sometimes too strong, then I export it unedited in 16 bit to CS and do everything there.

But a certain amount of vignetting is Ok - it belongs to wide angle shots. Here one of my PAWS - the dark border at the top does not disturb me at all.

Best limit the correction for vignetting in CS2 to less than 40%. I think PhotoRAW does a better job (less noise) but agree with the other comments here – it's annoying for certain critical shots, but you really have to live with a little vignetting…

Nice shot and I agree any vignetting in it looks quite normal.

Thank you

Thanks for all the comments and suggestions RFFers. While I admit some vignetting certainly looks normal and can at times enhance a photo, in other photographs it really is a hinderence.

I have been having some success with the dodging tool on CS (see attached photo) but the vignetting tool in CS seems a bit crude. I will experiment with the settings based on your suggestions.

I went to take the 15mm off the R-D1s body and found out the lens had loosened from the adapter a bit. That didn't help the vignetting at all ;>) Things looks "back to normal" now...
