Thanks for the information, Don. The SX50 has so many features both to try and try to master that I haven't even started to use the raw mode yet. But I look forward to it. I'm guessing that, like on the S100, Canon's in-camera processing of JPEGs using Sharpness, Contrast, etc. at defaults is the same as bringing a raw into DPP at its defaults.
That is possible. I have not spent enough time with DPP to do much more than an eyeball comparison of color balance, saturation etc at modest magnification. I run Linux as my OS and Windows only in a VirtualBox virtual machine within Linux. That means it is several steps to getting DPP up and running and I didn't find it interesting enough to do more than check it out on the first few raws.
I posted a review on this forun about a year ago that showed that conclusion. But I'm sure it will be fun to see the SX50's raw potential.
I've done a lot of tweaking of DNGs produced by my SX20 running CHDK. The advantage there over the ooc jpg is substantial. It is clear that the processing in the SX50 is far more sophisticated and the exposures appear to be more accurate and less prone to blowing highlights than those of the SX20. It will be easy to be satisfied with SX50 jpg-only output under many shooting conditions and especially to get some of the neat features like a speedy burst mode.
By the way, for those who don't already know, Photoshop CS can be set up to edit JPEGs in either 8 bit, 16 bit, or 32 bit. It has even more "features", I think, than the SX50 and is also fun.
I'm not sure, but RawTherapee may be the only image processing program that does all computations using floating point arithmetic. I wouldn't go so far as to say that you would be able to distinguish an image tweaked in floating point from the same image tweaked using 16 or 32-bit integer arithmetic but there are some Fourier transform techniques used in RawTherapee that may require floating point calculations.
