F.U.D. at it's finest.

I never understood what the underexposed pushed fur shots showed other than you should try to expose properly in the first place no matter what camera you use.

It's the exact opposite of "underspoed" )


OK.


So what is "spoed"?

Thanks Interested_Observer. I'm definitely curious to see, as I like night/astro photos as well. Though I'm maybe more curious about the results at 20-30 secs and ISO 3200, 6400 and 12800.

@MJKoski made the observation that ISO 800 images showed detail loss due to noise reduction, but found that ISO 100 shots pushed three stops didn't. That was his point about pushing under-exposed images, I believe.

... on the K1 or mkII?

I'll try to take those also... just of the landscape element - not with astrotracking.

You will never see any critical loss happening with targets sharp all over. It does not work that way I have already found out. You need to have very sharp plane of focus around which bokeh changes to total blur. It is the transition which fails badly.
MJKoski The PF first test scene seems to contradict your claims. The side by side comparison tool the K-1MKII handling of the bokeh transition is night and day better than the K-1. Both in the RAW and JPG. The RAW you can really see the separation of the flower from the background opening up a more 3D space around the flower. The K-1 image is really flat in comparison. The bokeh itself isn't even close which is better.

What does "overspoed" mean?
I don't know, it's freaking autocorrector and now I cannot change title ):

Interesting, didn't noticed that.

He noticed the issue on the K-1II after having previously owned the K-1...

If you are looking at DPR's K-1 photos and comparing them to DPR's K-1MKII photos, you are completely misunderstanding the issue that DPR's review has found. DPR is comparing K-1MKII photos at 100 ISO + brightening to K-1MKII photos at 6400 ISO. I.e., photos from the exact same camera and the exact same lens, just different ISO values. The photos SHOULD look nearly identical but they do not, due to whatever the camera is doing to process the higher ISO shots. That's the issue.
Worth noting that I have done this at home with my K-1ii and seen the same thing. It's certainly subtle, but its obvious enough that I got a room full of non-photographers (family members) to pick out which was which nearly 100% of the time from 100% crops. All of that said, I love my new camera and am pretty sure at this point I'm keeping it. I figure I can expose for iso1600 and then shoot at iso400 if I am REALLY concerned about the extra detail and any improvement in AF is very welcome :-)

I really hope Pentax enables turning off the NR functionality at least at iso 1600 and below.

It's neither under- or overspoed... One might say it's "perfectly spoed"

Isn't that the observation I disproved?

You might have, Alex... I'll admit I grew a little weary of the thread and stopped reading it

I'd be very curious how you disproved it when I've done exactly that about 6 times now. Bill Claff said the sensor for the K-1 was virtually ISO invariant meaning you should be able to push several stops (I only did up to 3) without seeing a difference between pushing in post or bumping the ISO. So if you expose for ISO 1600 and shoot and then jump down to ISO 400 and shoot again and then bump two stops in post you end up with identical images. The only difference is the accelerator is active at ISO 1600 and inactive at ISO 400.

There is less noise but also less detail in the image exposed for ISO 1600 than the image taken at ISO 400 and bumped two stops. Its not dramatic, but its definitely there.

Yes. mk2 is ISO100-400 camera when exposing an image now.

And mk1 is iso100-1600?
