Bernard,
Absolutely stunning photographs as usual.
I was out at this location the weekend before you.
We began our trek from Narada (950m) and climbed to the Notoridake (3,026m) staying at the Mountain Hut nearby.
The second day we walked along the ridge line crossing Ainodake (3,189m) to Kitadake (3,193m) before heading down Hirokawa to catch the bus back to where our car was parked at Narada.
During our decent on the Sunday afternoon, we passed someone carrying a sizeable (5 series?) Gitzo tripod and my friends started giving me a hard time that his was bigger than mine. I said that I would not be surprised if it was you (I had sent them a link to your Haute Route photos earlier in the week). Just a coincidence?
Unfortunately we thought the huts would be crowded/full so we carried full hiking gear (sleeping bags, mats, tents, stoves/food etc) so with my pack being 20kg I foolishly left my 70-200mmf/4 or 300DO at home. Could have really used the extra reach for the Mt Fuji shots and should have stitched for wider shots.
Are you able to provide some insight into your pano technique with the RRS gear?
Thanks for sharing your work.
