I did the north bit of the JMT last year, YV to red's meadow. Looking at finishing this year, end of August/early September, with an exit at horseshoe meadow (done Whitney already... but never been to Horseshoe).
I will have some time, planning to do this in 14-16 days including a zero or two or three if there is beauty to investigate

I was wondering if you would have wise advice for specific campsites pitches, and for potentially best spent zero days (not moving camp but scrambling and exploring days) ... Will be lugging the big camera again and a tripod. Already trying to aim for sites with sunsets/sunrise and astrophotography views by reading the topography.
I keep hearing very good things about Evolution valley and Rae lakes (most jmt/PCT hikers consistently saying it was amongst the most beautiful bits of the trail) so I am curious if you have a take on where best to camp there to enjoy these to the max.

thank you for your wisdom!
