Dave is a quiet guru. There is little he doesn't know. And very happy to share. A great contribution, long needed.

We’ll, some days feel like that. Most of them occur when I am doing things outside with or without a camera. I love being outdoors in the wilderness, and often say I don’t go outside to take photographs, I take photographs to go outside.
Lately, my real job has been taking up significant time, and as a result don’t get out as much I like. But I appreciate every wonderful opportunity.

Dave..... you are on a roll! Great article. I liked the tidbit about backpacks and having the bag open with the straps facing up(y). A neat little touch that I hadn't really thought about.

I agree with what everyone has said and really helpful with the information on the backpacks! I am measuring to optimize my Kelty Raven with inserts this afternoon. It may not optimal with rear opening but it is something I already have :) Looking forward to the next section.

Thanks for taking the time to share this information!

Fantastic articles, Dave. I missed no3, but just read it. Yea, the 10 step lens changing routine pretty much describes what I already do, with minor differences. Thanks for the writeups. Very helpful. I am still trying to understand no4. And apply it to tabletop macros that
I do. Read it trice already.

Thank you so much Dave! I appreciate the time and what has to be considerable effort into making an informative article. These have all been fantastic and I've awaited this latest as patiently as I could muster. I'm looking forward to digesting some more and trying some of the techniques this weekend. I've been trying to master tilt and I've been missing a few things this article nicely pointed out. Again, one of the things I appreciate about the people here is their willingness to share and teach. We need more of this in the world. :)
