It seems to me Sporgon and I are the only two who ever bother to post rebuffing Canon images and we are treated exactly the same way the DR's are. But yes it is very interesting the tone has now changed to the low end lifting capabilities rather than outright DR. It is also interesting to foresee the next battle ground about low end tonality, basically I don't see any whereas others suggest there is "massive amounts of useful data" down there, I then say 'there might be depending on your definition of "massive amounts of useful data" but there isn't any tonality'.
I don't get this. Dynamic range is dynamic range and it's always about the least bits and whether they are noise or signal. (or for displays about how much darker the deepest black it can show it compared to the brightest white) I don't see how anything has changed.
I know you don't.
"Dynamic range" in this arena has a definition that is based on certain base levels, and people will set their own base levels of how much tonality and contrast before x amount of noise. Think about it, in a given bit depth the measurement variable is the same, we are talking about 14 bit files, they all have the same potential, what we actually end up arguing about is the floor level at which the signal is no longer useful, people say Exmor has masses of useful data very low down, which I dispute, they also say Canon files floor, the point at which noise overwhelms the signal, is much higher than an Exmor, which I agree with.
Our dispute boils down to how useful and necessary that bottom bit of signal is, I contend that the low Canon signal is useless because of noise and that the Exmor signal is useless because it contains no tonality. They maintain the Canon signal is useless much higher than I do and the Exmor floor is much lower than the Canon. These are all personal decisions, they are not scientific measurements. What I can sell is different to what you can sell.
If jristas image had shown he could take a single shot of an interior and hold exterior detail I would have ordered an A7s this morning, but it turned out that in my opinion, my personal one, that both files are unusable, the Canon because of the noise and the Sony because of the complete lack of tonality and blooming.
Let's just be civil, okay?
You expect much.
These DR arguments end up with both sides pissing in the wind.
With that attitude, these discussions will never be civil. I tried to start a thread dedicated to DR discussion, didn't push any kind of agenda, and the thread was still derailed...primarily by the anti-DR crowd. So long as no one tries to react differently to the DR discussion (which is not going to go away...it's the only real issue Canon cameras have, so OF COURSE people are going to bring the subject up), then nothing will ever BE different.
How can it be derailed by people posting examples of the latitude the Canon sensor is capable of ? Actually something has come out of these discussions; there has been less talk of greater DR and more talk of being able to pushing 0 data. That in itself is a step towards understanding what Exmor really offers over the current Canon sensors. You want to push 0 data then I think we are all in agreement that Canon is not your camera of choice.
Exactly. Every time a head to head comparison shot is made, the images are so hopelessly underexposed that it is bound to show Canon in poor light. Real world imaging narrows the differences considerably.
You are missing the point. People are talking about real world images that are not under exposed. If you have highlights that are bright and need to be saved then the rest of the image may get pushed very dark, but that is not underexposure. That is proper exposure.
Yes that is what they always talk about, but never post. They always say "but what if the scene had more DR then it would have been DR limited", then we get a post like jristas where the DR of the scene actually vastly outstrips even the Exmor.
It turns out it is incredibly difficult to find these actual "real world examples" where the difference in sensor performance makes any real difference to the end image. That is why the "issue" perpetuates. Start posting dozens of real world images where there is a genuine real difference to the actual output image and there will be no dispute, but the pro DR base can't do that.
