I think there's photographers and there's people who talk photography.
For photographers, it's important to take pictures, for the others, it's all about chat-chat-chat!
Like you? Come on! I visit this forum and take pictures. It is possible to be a photographer and also read up on technology/techniques.
I think both of you are right. For me, it is about getting a balance between the two.
Let me explain;
The student asked the master: "Master, I have been practicing for years, and yet I haven't achieved anything much". And the master replied: "The idiots learn from their mistakes, the wisemen learn from someone else's".
Some people believe too much in what they have experienced and take that as the sole proof of truth.
It is crucial for me to take pictures. It helps me learning from my own mistakes, it keeps me enthusiastic about it, it helps keeping my self estime up. Practices make masters, right?
On the other hand, It is nice sometimes to listen to others; their experience, their theory and even their "idiotism" for lack of a better word. It, not only, helps in getting new techniques but some inspiration as well, it helps in understanding the need of others, it helps explaining some of my failures, but most of all, it helps in understanding the trend.
I agree, that we can take already great pictures with what we have and it would be wastefull not to take advantage of it, however haven't you ever wonder what if ..
What if we have the technology of after year today?
Today only 5-10% of panning are keepers, still too less hit punches are printed, too many endangered species are not archived. Just to name a few.
Yes, we need the technology to advance and I am keen to know about the trend. I don't consider chating about that as a waste of time at all. Just don't do it too much.
Yes, I am proud when I capture one of those rare moments, and yet I cannot remain in the technology of yester year and just close my eyes in front of lost opportunities.
Simply, I cannot live only with today and not to care about what to come next. It just feels nice when you see the light at the end of the tunnel.
