On 20150715Canon5DsTest_Stead_07 photo in dpreview review samples's photo gallery (7 comments in total)

Usual noise in the distant haze, but the detail in the middle looks medium format level to me.

I'm looking forward to the day we all wear copyrighted detection chips, surgically implanted (and linked to our bank accounts). Then when we look at or listen to copyrighted material we can be accurately charged for the priviledge. It's unfair that so many people gaze upon copyrighted material for free!

Looks pretty much identical to version III so far.

I laughed. It was actually pretty funny. Yes, it was silly, but in a funny way. I didn't think it was snide, sarcastic or sneering. Not Hamlet, but not bad.

But why is Barney 13 mb, and Sam a whopping 18 mb? Is it just the beard, or is he really 30% larger?

On Sources of noise part two: Electronic Noise article (234 comments in total)
In reply to:

DuncanDovovan: So in terms of real life photography, could we say this?

1) When the subject must remain low key, use longer exposures, lower ISO and position the histogram to the right, to make sure you have as little noise in the dark parts as possible.

2) If the dynamic range covers the histogram and in high dynamic range situations, expose normally at low ISO to prevent blown out highlights. Or use HDR through multiple exposures.

3) In dark situations, when you cannot lower your shutter speed anymore, because motion blur will become an issue and the available light prompts you to use high ISO values, you can under expose the (RAW) photo by dialling down the ISO multiple stops and adjust in post processing in order to gain dynamic range / keep highlight details that would be lost at high ISO values.

4) When you are a real noise ninja, larger sensors with bigger and more light sensitive lenses give you the opportunity to scale down your photos and thus reducing the noise levels that way.

OK?

On number three, if you have a high electronic noise camera you might be better off with shooting at a higher ISO, I think. It might not respond well to pushing much in post. But it varies, and you just have to experiment.

Really good work, the kind that makes me envious.

Surprisingly thorough and useful report for a product like this. Thanks. Hope to see more.

jkrumm: I've always exposed to the right, but no matter what people say, even with the blinkies on it's easy to blow some highlights, so my exposures have slowly moved a little left, and the modest increase in noise just does not matter. Digital sensors are much better at capturing shadow detail than retaining highlight detail.

Live histograms tend to be less accurate than the blinkies, at least on my camera. But it all depends on the subject. When I shoot faces, I usually want to expose for the face and let the highlights blow if needed. With nice side light into trees, I'll underexpose a little, knowing that the camera will not be right about the highlights in the raw file even in my EVF.

The images look like there's a decent sensor in it, but the lens only looks ok.

grasscatcher: I hope that they've thoroughly fixed their panorama stitching engine. My experience with PSE10 stitching was that it seemed to choke on anything more than five high-resolution photos, which is why I switched to MS ICE.

Just tried it with two rows of shots, 12 total images, worked well and fairly quickly, and saved as a DNG which is nice. Not sure if it would choke a huge number of images.

jkrumm: I just see Lightroom 5 in my updater, but with 4 million users they likely have to control the rollout a bit so I suspect I'll see it soon enough.

That worked, thanks. Had to solve a crash at start-up problem too, but apparently that's a bug for the whole cc program that is fixed by logging out and in again.

dialstatic: Edits to stuff in Aperture do not survive the transition to Photos. I'm sure it's a nicer app than iPhoto was, but I'm making the switch to the conpetition.

It actually seems a little worse than iPhoto at first try. I think aping the iOS app was a mistake.

jkrumm: I think I'll get one for my ski helmet. What's the video like?

Upon further research it looks like this is real, so I will not be getting it for my ski helmet. I don't even own a ski helmet.
