Thanks for your comments, Phil. Contrast is a personal choice. The files are pretty flexible and you can adjust to your liking in every which way given you got a good exposure in the first place. I use B&W light yellow filters when shooting with the MM.
The first two shots in post #4448 are with a 2/50 Planar, all following shots are with a 35'cron asph. I didn't have my 25 Biogon in the bag, I'll bring that the next time I'll visit this location. It is a pretty impressive scale, inside as well as outside. I guess the floor pieces of marble are about 2 ft wide and 6 feet long when you compare them to the people.
I was just quickly walking through and not really exploring the place. A little tricky when it's bright and sunny outside, so a filter is definitely useful to help with the highlights.
