PhotoPlus International is coming up soon at the Jacob Javitz Center in New York in October from the 19th-20th. I have been there many times in the past and I highly recommend it, even if you just go for the free trade show.
The trade show is amazing with hundreds of vendors all showing and selling the latest and coolest photography and video resources. I have learned so many things just talking with the sales people here and get to try and play with the latest and greatest of the new products as well as being informed of what is coming next.
