photomedium: IMO if every camera gets an award I question the point of a site dedicated to reviews. People sometimes like absolutes.

It's all good that there is no "absolute" best camera. Makes a little more work if someone really wants to get what works for them but so many options that can all produce great photo.

Merry Christmas to you and the DPR team. You do really great work.

Thanks for producing this. Very enjoyable.

In reply to:

MBell: What about the Dpreview of the A7Rii? The camera has been out for almost two months. Almost as though Sony has told DPreview to hold off!

Go Rishi Go! Look forward to the review after the honeymoon.

In reply to:

GPW: With so many adjustments to get to the final result, it's actually Adobe's photo that the photographer made, NOT photographed. Shows lack of true photography skills IMO.

If you read Adams' book, "The Making of 40 Photographs", he not only talks about the adjustments he makes (see Rishi's comment above) but also says he hopes to live to see the day that photos can be captured electronically for processing. When he took photos, he took notes regarding things he needed to do during the darkroom development process to deal with dynamic range challenges.

Great shots. Congrats on your upcoming marriage. Look forward to seeing what catches your eye in LA.

On article MIT proposes new approach to HDR with 'Modulo' camera (115 comments in total)
In reply to:

falconeyes: I now studied the original research paper and underlying math. Thinking about it now, the approach is more straightforward than it first appears.

The authors apply a cut graph algorithm ( https://en.wikipedia.org/wiki/Cut_%28graph_theory%29 ) which is the new kid on the block since about 10 years. E.g., the algorithm can solve the noise reduction problem for a 1-bit deep image *exactly*. They apply this algorithm about 2^(n+1) times to solve the problem for n extra bits in the clipped highlight region (for 2^n rollovers). The paper is all about this algorithm.

Unfortunately, the approach cannot provide infinite bit depth. It can only less than double the bit depth of the modulo camera sensor (due to the statistical properties of photon shot noise). Moreover, it requires a high spatial resolution to work for higher values of extra bits which means, the algorithm quickly becomes expensive. I expect the practical limit to be around 12 bits extending to 18 bits which is ISO 6,

Don't drown. Keep a balance. Too many things still to come and need you (and the DPR team) fresh and at the top of your game. Thanks for all you are doing to give us insight into the rapidly changing world of digital photography.

Good job this week, DPR. Curious if you have a A7R2 that let's you start that review, a step at a time, as you are doing with the Rx100 M4?

In reply to:

futile32: @Rishi Sanyal Thanks for the article. It nice to here that you guys are as excited about this camera as some of us.

I really hope Sony delivers on their promises too. Can't wait to see the review when you guys get your hands on it.

Celsus - What you mean is you, not people in general. There may be others but there are many who have no problem whatsoever with this approach.

In reply to:

Searching: You can hardly call these high octane samples, quite frankly I'm disappointed and was expecting more, these are quite average in every regard.

In every regard doesn't really tell us anything. Wondering what caught his eye or didn't.

In reply to:

paulfulper: where did they move the GLOSSARY and technical explanations of cameras and sensors ?

that was my main reason to come to DPReview.

Please help !

I asked the same question via feedback.

nananananana: I wish people would stop assuming that dynamic range is a defining factor when people buy these cameras. You do realize that you can't see high dynamic range from a regular photographs. The only way Dynamic Range might matter is for people who do very heavy post editing.

We dun care about dynamic range. Stop assuming we do. What I care about is:

-COLOR ACCURACY (thank you low pass filter)
-LOW WEIGHT
-CONVENIENCE
-GOOD JPEG QUALITY
-GOOD APS-C LENS SELECTION THAT ISN'T TOO EXPENSIVE AND LIGHTWEIGHT
-FREE SOFTWARE LIKE DPP
-ERGONOMICS

Canon provides all the above, which is why they ship cameras.

We do not care about dynamic range or micro adjust. And by we, I mean the target audience for these cameras. People who buy these cameras have a life outside of photography, they are not pro photographers.

It's nice to have information available for those with different priorities to makes their assessments and hence their choices. If DR not critical to someone they can evaluate the camera on the basis of those things that matter to them. Those to whom DR is important can do the same.

Did you establish the target audience in some manner that enabled them to appoint you as their spokesperson? DR can have varying importance to different people, even within such a target audience.

In reply to:

nananananana: I have been reading about the electronic spirit level of the 760D. I wonder how good this works, I can see myself using it for architecture, but I wonder if it will help much, because if the street isn't level, the spirit is going to say my building is not level, even though it might be, but the spirit won't know since it doesn't understand the street and building are not 100% level.

For a horizon however, I can imagine this to be extremely useful.

If there is one thing I hate, is taking a shot, and noticing later that it wasn't perfectly level, and having to go into a program to correct it. If this thing can assist me with getting all my shots perfectly level, that would be nice.

Streets are almost never level on purpose. Minimum slopes for drainage.

chillgreg: Only 1 2000mm sample??? Of a mountain with no fine detail? That's the headline feature! What's up with that @Dan?

The phenomena is well known in astronomy and so no surprise that it can come into play in certain situations for super telephoto shooting. There is a reason they put telescopes on mountains to get above atmospheric distortions.
