Always good to see how others approach things, creatively and technically.

The scene comes up with iPhone 7 in both boxes. When I attempt to select iPhone 6S for comparison it only shows Low Light for the 6S?

Is image stabilization a notable difference?

Maybe there is an easy way to see before and after but doesn't seem so?

On article Upwardly mobile: Sony a6300 Review (2156 comments in total)

Does the inclusion of 4K video mean that the sensor technology used in the A7M2, enabling fast response time, mean that the A6300 will be able to support improved phase detection focusing for Canon EF lenses via adaptor as seen in the A7M2?

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.

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.

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 ( ) 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.
