I completely understand what is being said there and I agree to a point.
My photography interest lies in landscapes. I think the main reason I became so interested in this type of photography is because I love soaking it up while I'm there. I do take my time and relish the moment, so-to-speak. It's my escape from a busy life. So I completely understand his rationale. For me the photograph is a reminder of the moment that I enjoyed there, not the object itself to be enjoyed. It's the documentation of the relish.
I'm not a sports or action photographer. I don't do animals in the woods. I don't do race cars. I don't do weddings anymore. I will take my camera with me when I can, but it's not the first thing I reach for every time something is happening.
That being said, I understand the need to capture moments as well. But I do believe with some it's obsessive....almost as if life existed for the camera instead of the other way around. But it all boils down to choice. If someone wants to snap pictures and not take stock of what is going on around them in reality, that's their choice and their loss.
I will do an occasional airshow shoot, but that's because I've been in airshows from both the flying as well as spectator role, so not much is new there to me. I just love the aircraft. But if you are going to your first airshow, by all means enjoy it all. Bring your camera but don't forget to remove it from your face every now and then. A picture is not the same as the real thing.
