Photographic techniques I use.
Beyond hyperfocal distance: Getting the right parts of the scene in focus
Depth of field brackets on cameras are quite handy to start a discussion about picking the right aperture to get a desired depth of field and suggest the concept of the hyperfocal distance. I wish more lenses had them. I've got an old Vivitar Series One lens that has a quite pleasant set of depth of field brackets that work at any zoom length. Modern zoom lenses don't even try to get this right.
The real name of the game in future sensors
If I look at the advances in sensors and sensor processing that are coming out of the labs and sometimes even shipping in products, I realized something interesting. The game has changed at the research labs. See, previously, the goal was to make a sensor that had the highest resolution. Now, the goal is to still ship sensors with more megapixels but without changing the "real" resolution. And this may be a good thing.
