K-5, low light portrait testing...

ogl · 10-18-2010, 08:37 PM

ISO12800 has the strongest NR in RAW of K-5.
(info from Oleg_V)

But, to say honest, rather smooth work.

And photo looks fine for me to print 15*20 cm.

dgaies · 10-18-2010, 08:56 PM

Just thought I'd throw in another 12800 shot from the same series. This one was just opened in LR with Luminance NR set to 14 and Color NR to 41. This is not to suggest this is a good way to do NR, but just to see what a 10 second effort would produce.

Also, I adjusted the white balance just by selecting a point on the steering wheel. Doesn't appear to be much (if any) magenta tint to the image.

Really amazing image. Even after seeing all the high ISO shots, I'm still shocked.

There ist some problem with the images in the initial post. They are no longer visible. Seems to be some problem with a bandwidth limit:

"The server is temporarily unable to service your request due to the site owner reaching his/her bandwidth limit. Please try again later. "

Could you provide an alternative source to watch or to download?

Yep same here.

Morning John, Any news on RPP processing. From what I have seen it might help a lot with the K-5 dark files.
I am even irrationally pondering on working on a mac to see how it works.

I'm working on it as we speak.
TBH. I'm pretty left handed with RPP(a noob)
And it's taking its tole on my ability to process files properly.

ie. I love the film style rolloffs and highlight recovery features(work and look great). But... I'm at a loss as to how to properly meter a scene. RPP is seemingly telling me everything is way under exposed by default which I know isn't true. Though I have no way to assessing and adjusting that portion of the development either.

Another issue I'm having with RPP is in managing color casts etc.
Which leads me to reprocess images in ACR(no too good) and so I just don't feel up to the task of using RPP proficiently at this point.

Trace you some NR tips for RPP ones if you're up to it

Either way, have you seen this unprocessed RPP sample?

Quote:

Have you seen this K-5 RAW file? You can grab the full size(low Q) sample at the bottom to examine for yourself. N.B. a shadow recovery of(.45) was done in extraction, so there's still a little room for improvements.

K-5, ISO6400 RAW - (NO NR, OR PP)

Full size sample(low Q): http://www.bertin.ca/tmp/K-5/K-5_vs_D700/K5__1050_1_2.jpg

JohnBee · 10-19-2010, 03:43 AM

Updated images, RPP samples(early attempt).
Hopefully they will improve, though already, they are showing much more detail than ACR

I've updated the low light portrait samples today(after a good night of sleep)
For your pixel peeping pleasure

First things to note is the exposure(things could be better):

UNPROCESSED RAW, K-5, ISO12800, f/5.6, 1/60s

UNPROCESSED CROP, K-5, ISO12800, f/5.6, 1/60s

PROCESSED RAW, GLOBAL NR, 1 PASS, K-5, ISO12800, f/5.6, 1/60s - (Click image to view full size...)

Click image to view full size...

PROCESSED CROP, GLOBAL NR, 1 PASS, K-5, ISO12800, f/5.6, 1/60s

... then end

@ JohnBee

If you write "global NR, 1 Pass" you mean applying TopaZ Denoise with some kind of preset, I assume. Am I right?

More or less.
The main idea is to convey that I didn't use any advanced NR methods here.
So anyone can do this in less than 3 using typical tools.

PROFILES:
no profiles actually, Denoise is far to simple to be messing with profiles.
In fact I deleted mine off my HDD the day I upgraded top v5.

Having said that, here are the settings.

PS. In case you're wondering, I didn't crop out the profile panel for any reason other than to focus on the essentials

Xatnep_CJ · 10-19-2010, 05:16 AM

Than you JohnBee.
I think I have to download a TopaZ Denoise trial version. Th handling seems to be much more intuitive compared to NoiseNinja.

Let me see if I can reproduce your stunning results...

Thanks these are remarkable, I also have topaz 5 but what about lens profiles in Adobe ACR 6.2? I see none.

Don't forget to remove Chroma in ACR/LR(always).

Set everything else: 0
No lens profiles: just default
Though you could just as well use one(im only stating my own recipe).

NB! I also have ACR/LR Defringe set to: ALL EDGES
It acts as a free(small but helpful) chroma removal. I have it set on by default in my ACR default settings.

Most of the DNG/RAW's have been released(posted) here for members to download and work with. However, some of them(such as this one) are not approved for release.

However, you are all set to process the same quality of images as is shown here with the tools you have given the relative ease needed to create files like this with the K-5 system.

I know alot of people are under the impression that I'm waving a wand or applying some secret sauce to get images, but, nothing could be further from the truth.
The secret is in the K-5's amazing ability to render excellent high ISO images(no more no less).

Anyway, here is the link to the RAW file from this thread.

Thanks both of you - very much!!! Just so it's clear, my OP in this thread was a general statement about trying several NR plugins on sample K-5 images, not necessarily these specific images.

Regards,
Marc
