Perhaps someone can confirm this:
on the X10 in raw+jpg mode and size=M (6MP) when you set DR200 or 400 we know you get the HDR blended exposure effect. But what happens at DR100?
The logical thing to happen would be that you get the SN pixel binning effect as the sensor is no longer doing the HDR blending.
It would be useful if it did work like this as you could then reduce noise when you don't need the dynamic range boost. In effect, DR100 would be like having a 6MP sensor with the pixel size of the 1 inch sensor used by Nikon and Sony.
If it doesn't then, there is no point at all to the 6MP DR100 setting.
Anyone know for sure?
Know what, I think I'm beyond caring.
The biggest thing that is being ignored, is what people are happy with in the final result, in what they see in their final output medium.
What I see with my own eyes in front of me from my screen here, and the occasional print I do, as well as the few I publish on the web, is all that is important, as far as I'm concerned.
As I've said many times, for my own needs, and preferences, it seems to me that an L size Raw image produces the most pleasing results overall, on most circumstances. However, I do agree that some of the other EXR modes are beneficial in the scenes that make the best use of them.
I'm not sure if any of the recent threads have even helped anyone understand anymore about it either. With talk of pixel 'binning' - which is not really a grammatically correct term for what happens - ISO boosting, and various combinations of guesswork, no-one actually seems to have any 'facts', other than from their own testing. Of course extensive testing by a competent person should give us some good data to work from, and I suspect somewhere in all this the truth does lay.
I have to say that my own arguments against some of the 'facts' represented here have been born from scepticism by some methods used. For example, I see an awful lot of images posted for viewing here, and my own interest is in results from Raw files only. However, to be able to view any, they of course need to be exported for web viewing, which usually means a highly compressed, and scaled down version of the original.
If we're supposed to actually make proper judgements from those, then it's no wonder we have so many arguments. Surely those versions are not necessarily going to represent anything seen by the originating poster on their own screens, in their software of choice.
To be honest, much of this arguing is moot, unless you can replicate all the conditions equally for every viewer. Every graphics card will work slightly differently, as will every display - not many here mention anything about calibration, so arguing about colours or tonal quality is pointless.
I also see mention of up/down scaling images so they match. That is also another factor that can affect the image, and the quality of the algorithms used may well cause an image to be represented falsely. No-one mentions what settings, or methods are used for the scaling operation.
Ultimately though, and as I say, it's what you see in your end results that matter. If you're happy with them, then why not stop trying to fix something that isn't broken?
If you're trying to improve things, then the best thing to do is to go out an learn the capabilities of your equipment, and it's limitations, and also try to improve on your own abilities, rather than simply take a set of numbers you found on the web, and assume they are the best.
