Thanks for your feedback.
The images were taken on a wet day in January 2014. Shot on a MEfoto tripod, locked vertically on an L-bracket/handgrip with manual focus and exposure lock. The image was made from 9 vertical exposures.
In SPP, I'd choose one of the 9 with the highest dynamic range, then wind back the shadows and highlights using exposure and fill-light. I'd save this as a custom profile, then in the list view select all 9 images and apply that saved profile to all of them, saving as 16bit tiffs.
I then opened the tiffs in Autopano giga, which automatically detects the order, etc. Generally I use mercator projection for these wide panos if there's not too much detail at the top and bottom. After cropping in autopano, I export to 1 giant tiff - approx. 400+MB.
I then open the tiff in Photoshop for further tweaking. In this case I used a series of layers and masks to bring in a more cloud detail, while keeping the high cliff on the right still illuminated. The central sky had a weird reddish cast due to the DP2M's well known colour issues... so I desaturated this to try to get the sky more uniform.
Crunched down to fit on dpreview...
