Is the RAW file for this photo available for download somewhere? I'd love to see what LR3.2 makes of this.

Yes, it's in my original post from last night. I'd find the link for you, but I'm late for lunch and there's a mob of angry co-workers who want to eat! Just look up threads I've started and it should be easy to find.

Thanks (for others, here: https://www.pentaxforums.com/forums/pentax-dslr-discussion/119157-last-one-no...o-51200-a.html)

Doesn't work for me though, site's probably banned in China...

Here you go

EDIT: if you want to play around with the raw file, you can download it here.

Would you be so kind as to let us have your exact settings in ACR on import and in Denoise 5.

I would be more than happy to share the whole 3 step process with you(step by step).
I'm actually writing-up the thread, as I am writing this.

Well.... not literally, that would mean that I was actually writing two things at once,
But you get the picture right

I'll publish it for you in a few minutes on another server...

I really appreciate you taking the time. I want to eliminate my "dumb" factor from the equation so to speak!

I am willing to learn

Thanks very much. I'm done downloading in case you want to take it offline.

In lightroom the image also cleans up very nice. It seems you can make a fairly big print and get away with it

[climbertrev]

Nah... This can't be

Agreed
What? So little noise at ISO 51200?
A stellar jump
Or, as the late Douglas Adams might have said
"Who turned on the improbability drive"!

Or could it!

Unless you two have been fooling around with us -

I am totally amazed

Well we finally made it!

Thanks to dgaies's outstanding patience and contributions, we have managed to explore the entire usable range of the K-5's sensitivity performance.
When I think back and remember no less than 6 months ago(I think), when a Pentax official told me that the new K-5 would give FF a real run for it's money. I can't help but think that had I not see this with my own two eyes, I never would have believed it!

But here it is:

K-5, ISO51200, 1/40s, 85mm, ƒ/5.6 - Click image to view full size

Click image to view full size

The simple fact is the K-5 generates RAW files with unbelievable amounts of detail. And just when you think you may be nearing a ceiling, you find out there's yet more of it to go!

Anyways... here's the best part....
This file was processed with ACR and Denoise in a SINGLE PASS!
No layering, no masking, no fancy-shmancy anything.

And so, I beleive the proper term here is: 'K-5 OWNAGE!'
I would like to thank everyone for helping out and participating as testing moved along. And I look forward to helping others on these forums reach similar results as well.
So thanks all and God bless.

...the end

Very good, hey John how big can you make this on print? would A3 size be great for this kind of high ISO? also I too have denoise 5 but if you were just to use only ACR 6.2 would you get results like this? thanks

Hey guys,

this time you played a little trick, I must say.
The RAW file is about one f-stop overexposed which makes it an ISO 25600. As we have learnt during the last days the K-5 produces high ISOs by pushing ISO 1600 underexposed images. So by overexposing an ISO 51200 by one f-stop the result is more or less the same an exposing an ISO 25600 correctly. This should also have an influence on the noise level.

I would be verry happy if you convince I am wrong.

Here's what the actual metering(and RW lighting) looked like
Still think were playing tricks?



If we would have published the image to reflect RW lighting, most people would have complained that the scene was to dark anyways.
However, since the camera was maxed out, I think the system meters to protect highlight at all costs.
Having said that... with sensitivities as low as this, it takes very little to throw exposure out of bounds(very little room).

As big as any other print from this camera.
No need to reduce anything, the file looks great at 100%

[Xatnep_CJ]

To produce more or less the same visual impression in Lightroom 3 I have to reduce the exposure of the RAW file by -1. This should kill some of the noise. But anyway, still impressive.
