Henry, as I recall from a previous post you are going to use the 32mm Rodenstock.
If that lens or any other tech camera/Rodenstock or Schneider lens is in your line up, you will need
Capture One to generate the LCC for each series you take. If you use the DF body and traditional
glass you can use Capture One or Lightroom which ever you prefer. I don't know of a way (wish I did
for Lightroom to take out the color cast/vignetting etc. created by the lenses I use with the Arca rm3di.
The Rodenstock 32mm will have colorcast issues (all the lenses do) which only can be fixed by a LCC.
As for vignetting, I have not shot this lens, and have no opinion. All the others in the S family, I have shot,
23, 28, 35 and all vignette to some degree and IMO require a center filter for the best exposure. Even if
you use the center filter you will still have colorcast issues that will require LCC correction. Shooting without
the center filter most likely will require LCC for both colorcast and vignetting which will require Capture One
since you are using a P65+.
I guess you could open the images in Capture One first, and correct LCC, then save the image as a DNG
and then open the DNG in Lightroom. I have thought of trying that but have not as of yet.
As for which program works better? I prefer both as I feel that each has areas where they are superior to the other. But with the beta of LR4, it's gotten very close IMO. (I don't shoot tethered which is another big reason
for Capture One with a P65+).
I hope you will post some images once you get the 32mm!
