All these photos is crafted by amateur mountaineers, excpth one.
Photo 3 is crafted by a professionally large format photographer, now retired, has written many books with many such nature photos. This dog photo is his lovely memory of that particular trip, as he says, this is how he remember the trip and the people with him.
Photo 4 is crafted by another young one mountaneer. A snapshot from the same summit as photo 3. In fact, if you turned around, not looking north in the valley, instead looking south at the next summit above, you will get this photo. Oh yes, that cliff is the next, it aint that difficult, you have to climb it or go home. I tried to suggest once for the old one to recompose, bring in them scary peaks, ......
For completeness; Photo6 is the smal ridge further you have to "walk" to ascend the topp peak at 1328 m asl, from the second summit 1299 m asl, above the photo3, on top of the cliff shown in photo4. Same photographer photo4.
The last photo, photo 5, is one of my latest snapshots. Not with my D750, alas my LX100 pana, which is way to small for me to handle. I must have done something rigth. I got many, many, many good likes and wows for this, havent got that much acclaim for months :-)
