K-3II High res mode ??

So a few questions for K3II owners.


1.) Anyone use the K3II high res mode to shoot a waterfall or moving water and what was the results?


2.) Anyone use the K3II high res mode with a 10x ND filter for landscapes and did it work?


I had a K3II for a week, but the not turning off bit made me nervous so I sent it back. I'm thinking of trying it again, but I was wondering if the High res mode would work in these two landscape scenarios. Thanks.

You can't use pixel shifting if anything's moving.

Even if you want the water to blur in a waterfall shot or the sky and water to blur in a 10X ND shot?


I'm trying to understand why it wouldn't work if it won't.

It's an interesting question. You can do it but results will be curious, and noise would improve with four exposures. Any shrubbery would look poor perhaps, but water itself on a fairly long exposure..?

Someone is bound to try soon in any case

As soon as I get a working K3II and a waterfall, I'll let you know...


I don't see how a the high res mode could blur things any worse than a 10 second exposure could with a 10x ND filter. But I prefer actual results to thought experiments, and my brain hurts thinking about it.

You'd probably get pixel-grid patterns, due to the nature of the beast, and not (not only) a uniform blur, esp. at tge edges of the waterfall, where you might have a water spurt in one exposure and not in the others: hey presto! checkerboard effect... :-\

Let's hope so! We have so much falling water around here, it would be a nice feature.

So you want silky smooth water with high detail?

No, I think he wants high detail in the static parts of the scene.

I also suspect that it will not work well in the water areas of the picture, based on the strange artifacts I have seen in other sample images where foliage has been moving in a breeze. Perhaps if somebody didn't mind spending some time post processing the scene, they could do a single, regular long exposure for the waterfall, and then do a pixel-shift image, and then copy the waterfall into the pixel-shifted image.

Really? I don't spend that much time around here, but is the general level of photographic knowledge assumed to be that low these days?

Something like that for the 10 stop neutral density filter....





And like this for the moving water, with all the stuff that's not moving really really sharp.

Yep, that is the use case and those sorts of subjects are common enough in this part of the world.

BTW...really like the photo from Anthony Lakes...

This could work fine if you average a couple dozens of short, high-resolution, exposures.

I was making a joke but I guess that did not quite get through so sorry for the confusion. Maybe a language barrier or cultural difference.

My bad.

No worries. A smiley face would have helped understand the intent... I just took it as assumed lack of knowledge, which probably isn't too far from the truth usually.

From what I hear my dad just finished putting in a waterfall at his house in time for his annual 4th of july party, and I'm bringing my k3-ii and a tripod with me so I should be able to test this out. Don't think it's too large of a waterfall or a lot of moving water but could potentially be useful for purely scientific reasons.
