The easy answer is: some people will consider it a good photograph, and others will not.

The difficult one is: asking why is like asking if people like cats or if they enjoy eating mushy peas with their supper. Knowing if people like or dislike those things might help you gain an insight to their personality, you might even find out why they like those things. But does it in any way help you understand whether you like cats or mushy peas?

In case it helps, I very deeply respect the level of Adams's craftsmanship, his dedication to photography, and his willingness to share that knowledge as a teacher and mentor. That's about the extent to which I can appreciate his work and person.

As has been established, it's a very successful photograph, from a standpoint of selling prints and exhibiting them.
