I was just thinking today when I used to shoot with a group of photographers there were a few of us who had connections. Or someone had a desire to shoot something that none of us had thought of. Once we got access to the Woodbine Race Track through someone. Another time I discovered an abandoned hotel in Toronto I had never heard of. Or I would never had visited the Toronto islands without them.
Everyone in a group has a different background and something different to offer. I remember Ramses Moya working for Sun Microsystems who traveled the world and took his gear with him. The pictures he shot are incredible. And John Riddel had a press pass so had access to emergency scenes to shoot pictures, most of which are breathless. There were a few other guys that were amazing at it as well that I will have to look up.
Some shot digital, some film and some slides. Ramses even shot the famous Agfa Scala black and white slide film.
So being in a group has many benefits.
