Any thing Shot with a 5ds/r

Thanks, Eldar. I'm downloading the CR2. Based on your crop, that push looks ok... I do see some color blotch, although it's fainter than in any other Canon RAW's I've seen to date. It also does not seem to have banding. Both plusses. I am curious, however, about the artifacting? I am not sure if that is just JPEG compression artifacts, or some kind of noise characteristic.

Well, the CR2 is done. I'll take a look.

Chuck, that's not a suitable test because the original is not totally black. There is some light still in it, and some data has clearly been recorded. To be quite honest, judging by your beautiful wedding pictures shot on the 5Ds, your photographic ability means that you don't really have the lack of skills necessary to under expose enough for this sort of comparison. For novices in under exposing techniques like yourself a safe starting point is to leave the lens cap on.

Now, now, Sporgon. ;)

Love It, Scots Humour, keep in mind Sporgan, generally doesn't work with our American Cousins, we Aussies have a similar problem, with pretty well everyone that's not Aussie, English, Irish or Scots ;D

no worries, it's all good. We have senses of humor here too, just haven't had time to post!

And you do, no doubt, my apologies Chuck, my post re humour (note the spelling Guys), was an attempt to lighten the post, as I'm sure was Sporgons.

And as Jack mentioned, one of the attractions to CR is the amazing humour, spliced with a little tech, skills learning, appreciation of Photography, and angst watching.

OK Jon, I´ll give you an example. I´d be happy to see your response. I´m on vacation up the northwest coast and shot this for an HDR series. It is deliberately 3 stop under exposed. I have attached the original image, one lifted 3 stops and one small crop. Below is also the dropbox link to the RAW-file. Feel free to download and play around with it.

https://www.dropbox.com/s/n32t5ic9o7yfadl/_23A1096.CR2?dl=0

Thanks again for the file. I am happy that there doesn't seem to be a hint of banding there. I think that is the first time I've ever seen a Canon file without banding. It may still be there deeper in the shadows, but in this image, it's not, and that is definitely an improvement. I cannot lift shadows three stops on my 5D III most of the time without banding.

The data still has Canon's classic color blotch, sadly. I don't know what gives rise to that exactly. I was able to clean it up with 85 color smoothing and 35 color noise reduction. That takes the wind out of the rest of the colors a bit, so the rock face is less lively.

There is still something "rough" about Canon's random noise. Something I don't see in Sony's. I am guessing that is simply because the noise levels are higher, some ~3e- vs. ~13e-?

Anyway, it's an improvement over it's predecessors for sure.

The attached image is 50% downsampled, and is with +3 exp, +40 shadows, -100 highlights, -70 whites, as well as curves of +20 highlight, +40 white, -30 shadow, -5 black. Upped clarity to +33, saturation to +15.

Thanks Jon, Interesting. I rarely push shadows as much as this. In fact I cannot remember when I did that the last time, so it is less of a problem for me. I understand that for your astrophotography the situation is very different though.
