Third Party Manufacturers / Re: Dynamic Range - Try it for yourself, conclude for yourself: 5D III vs. A7r« on: October 03, 2014, 06:25:52 PM »
I understand that this is an area of your expertise, so I mean this as a proposal for discussion, not as a statement of fact. I think there is a difference between photographing such a space as a pro and as an amateur. I'm an amateur, and I've encountered the bright window problem. If you're a pro, you'll try to schedule your shoot when light is favorable, or perhaps you'll bring in some of your own lighting to balance the windows and the existing fixtures and lamps. As an amateur I don't do that: I stumble upon a scene I like and whip out my camera. It goes without saying that I shouldn't expect the same quality a pro would get with a properly set-up shot; however, I still want the best I can get with the 2lbs of metal and glass I happen to be carrying. If brand x sensor is better for that than brand y, then I'd like to know that so I can work it into my decision making at my next purchase.
Would you agree that the pro vs. amateur perspectives on this room are different?
I'd agree that anybody thinking either are acceptable shots is a whole world away from a paying client above real estate listings, yes.
But as an enthusiastic amateur I would say you would get vastly better images in that scenario with either camera choosing the window/exterior view, or the interior as the key point for a single shot, or take the time and trouble to make two shots, even hand held, that can be used together to make a good image that will do the job much better.
I accept that lighting, time of day etc, is often beyond even pros capacity to control, but there it is still an easy way to take the shot much better than it was done with either system.
I will also agree that there will be a rare occasion in that type of situation where you can "get away" with one Exmor exposure rather than two Canon ones, but I'd venture the two Canon ones would give you a much better image anyway!
In truth I did learn something from the files, that was that from my perspective the tonality of heavily lifted shadows is very limited, if the lifted areas only account for a small area of the scene I can see some utility to the capability, but when the areas to be lifted become a larger part of the image, even thought hey have little noise and no banding, I can't see the practical benefit for my uses, if I had I would have had an A7r here by now!
Part of that could be the Sony's lossy "raw" format. I haven't used any of these, so I can only speculate.
