Perhaps there is no much of an appetite for delving into technique on this forum. I say this because I dish out a lot of technical responses to questions and usually they did get very much traction. That's alright I figured out that I have a small audience but there is not much feedback.

There are just lots of folks that just feel the answer to most of their photographic aspirations, questions, challenges and solutions are equipment based. Someone will post an image and ask which lens the should have used or purchased to improve an image or improve this type of image in the future. If I answer and imply or suggest that the lens they used is perfectly fine but perhaps they are no using it correctly- that does no go over well. Some folks want o know what flash to buy but there is little or discussion of the dynamics of lighting- which, by the way, could fill an encyclopedia or at least constitute a special forum section.

This thread is too typical. The OP wants to know why there is not more discussion of technique but the discussion turns into a post-processing pro and con thing. Post-processing is nothing more than a methodology based on many techniques- it's part and parcel of digital imaging and should be discussed in detail rather than argued as means of fakery or fixes for poorly crafted photography.

Automation in photography precludes thechique?- that's nonsense! Nor does film photography require more technical skill than digital photography- it's just a bit different. Most of the same theory applies- just different tools.

To the OP: If you want to discuss technique- just ASK. Pose a question, write an article, and guess what? There are many talented and knowledgeable folks in this forum that will provide conversation, answers and solutions.
