Steven, the "vignetting" to me looks like natural sky vignette away from the sun, because it's off-center. Unless you were using a significant amount of sideways shift? Considering the detail in the shadows on the lower left/right, I see no reason to use a CF myself - it would just cause more overloaded highlights in the top area.
Steven. I agree the vignetting is too much especially in the upper left and upper right corners.

I just noticed you said you used "manual dodging". What did you do?

Probably what I've talked about doing for years, using a darkslide to "dodge" the exposure just like you would in the darkroom, by waving it in front of the lens for a portion of the exposure time instead of using a GND. Of course this can sometimes be unpredictable, and certainly decreases the exposure in areas that would already be underexposed from fall-off, if you're worried about such things.
The vignetting is natural, I used no shift on this shot that I remember. It isn't really the vignetting that bothers me as it is to be expected with the a giant ball of hot gas coming up over the horizon. I made a mental not of the sky at the time of the shot, which I noted was purplish. Its the color of the sky that is annoying me. I believe it is correct, but it bugs me.
Yes, I took a dark slide, figured out where I needed to place it to dodge the rising sun. I turned it so the corner was pointing straight down to avoid too "dark" of vignetting in the corners that a typical grad nd would give for a shot like this. I think it worked okay as i didn't entirely blow out the sun.
As for a cf, the only reason I mention it is there is always a much brighter spot dead center of the frame with sweeping landscapes, and bright skies and ground is in shadows. I can usually fix that though. I also only get the major vignetting at sunrise and sunset.
I wonder what your exposure setting was and if there was a reason not to use a GND in that situation?
Based on shadows it was something like a minute or so t f/32. Portra160. I assume you are asking why I chose to dodge with a dark slide as opposed to using a grad nc. I chose not to use a grad nd given the strong sunlight coming up on the horizon, uneven terrain and the strong vignetting that the 75mm Nikkor has even at f/32.

Yeah it is portra. I was working on another image shot on fuji and typed in the wrong thing
