p.3 #20 · p.3 #20 · Interesting Reference Data on Dynamic Range - 5dsr | |
I'm a math teacher and I loaded up the DR graph with 5dsr, pentax 645z, d4/s, d800/810, 5dmkiii, phase one iq250, canon g1x, sony a7rii. I'm always leery when so much data gets crunched into a single graph.
It's great to see the differences on the graph but ability with camera, planning , execution of the plan, and post-production make the differences I see in the graph less profound.
But it's another tool in analyzing what would be a best purchase for an individual and their specific needs.
In my own mind, knowing my ability to parse these differences in my final work, anything less than a one stop difference isn't that important taking into account the differences differ among cameras at different iso values.
My most important work I always try and do at iso 100 or thereabouts but I often find myself not using my cameras in the most pristine conditions even if it's not my intent and iso then goes into the zones where the differences in dr start to get close.
I wonder if others have put a theoretical value out there for dr for their own work given their own personal goals and abilities when making purchasing decisions.
One value for me that was striking is that by iso 12800 the dr values are around a half or so the max dr for that camera. You would think a picture taken at iso 12800 would be deleted immediately. Yet we compare cameras at higher iso values.
My struggle is owning the pentax 645z for my summertime landscape photography, but owning several canon lenses for my school year sports photography. I winced when the 5dsr came out and I was using my 1dx for macro photography with the canon 180 f/3.5 macro. DR wouldn't be at the top of my list in my decision to sell the z and get the 5dsr.
Understood I'm bringing another variable into the equation by talking about lenses, but lenses are far more important to me than the differences in dr among the same class of camera I see in the graph.
