Technology obviously changes our lives in many ways. For me camera technology changes over the last 20 years or so are the only real reason I still do photography.
Back in the 80s I bought a Minolta SLR and a decent telephoto lens. I shot a few rolls and tried to learn how to do it, but something just did not click with me. The barrier of having to work through film eventually just made me give up. I would never even take cameras on vacations, because I found vacation snapshots dull.
Then in around 2003, because of photoshop, I started getting into photo manipulation and digital painting. So I bought a canon power shot g5 I believe for taking texture pictures when I went on vacation. I shot tons of pictures. There is no question that the immediacy of it made it more satisfying. I still did not produce many finished shots that I liked, and didn't even use all that many of the textures. So the camera still languished a bit, but I did still use it and took it on vacations for more texture shooting.
Just before a trip to Japan in maybe 2005, I learned about HDR and truly loved it. I did a few HDR experiments there and produced some things I really liked from an artistic standpoint, ,and have been shooting more ever since.
But another big step for me was the purchase of this Canon G11. I have been using a digital rebel for some time. It is a good camera, but anyone who has one knows that the interface experience is not joyful. It has a shockingly lame lcd, and I was always annoyed that my wife's little point and shoots had these big bright beautiful lcds. But I really did not realize how empowering a big lcd on a swivel with live view could be. It is brilliant. I don't ever want to be without one again. Even though I keep thinking I should go back to the Rebel and use my better lenses, I don't because the G11 is just such a joy to use.
It occurs to me that wireless flash must be such a transformative thing for people that use flash, but given that it existed at the point I started, I will probably take it for granted.
I sure hope they start rolling out large swivel mount lcds on high end DSLRs. For my next camera the must haves will be full frame, swivel LCD, and live view. Do you think there are barriers to professionals adopting the swivel mount lcds? I guess you could just tether to a netbook or something, but that isn't very portable.
