Hi:
I'm an advanced amateur photographer but I haven't been to NYC since the '90s. NYC Photo Safari offers multiple tours depending on your schedule and interests. I did back to back what the company called Iconic NY P1 and Iconic NY P2.
There were 3 of us in the group as the 4th participant was unable to join.
Zim, the pro and owner of NYCPS, taught us many things. The pace is actually quite doable since it combines short lectures during the walks. You will take at least one subway ride to get to these places.
Whatever your level, Zim will be there by your side with helpful hints and/or suggestions to better your shots.
I also did the special, once a year "9/11 Tribute Lights" tour which was INCREDIBLE!!
