panos_m: Question: does it shoot 1:1 aspect ratio or does it have at least a viewfinder framing aid to shoot 1:1? Thanks.

@Carey Rose. Thank you! Does the EVF grid has the two vertical lines for 1:1 framing? Thanks again!

panos_m: I think this is a first for a Nikon DSLR: Aspect ratio 1:1. I assume that there will be a square framing aid in the OVF. No?

I was mistaken. It's the second with 1:1. The first was DF but only in LV. Two vertical lines in the OVF grid are enough IMO.

mvmv: Hmmm… how about highlight recovery test?

Rishi please write an article about this. As you see from the first response after your comment people still believe that there is a difference in the highlights just because there are differences in camera light-meters calibration.

Quest21: My Nikon D7100 can recover lots of over exposed highlights in RAW. I wish there was a test between cameras to see how much highlights can be recovered in RAW...

The HL range of the DR is the same. The reason that someone thinks is different is because there is more or less hidden negative exposure compensation dialed in the camera light meters.

A 18% gray (a gray reference card) is the amount of gray that separates the HL range from the shadows range.
From 18% to pure white is only 2.47 stops (as explained in the article I linked above).

2.47 stops is too narrow so camera makers calibrate camera light meters to less than 18%. Some as of 12% to give its users a little more HL. That is essentially a dialed in hidden exposure compensation and does not mean that digital cameras have different HL range.

Spot meter a evenly lit surface. Add 3 stops of exposure and you are near or over saturation. Where are all the other stops of the 10-14 stops of contemporary digital cameras? Answer: in the shadows (bellow 18%).

The variance you see its because the cameras you are using have their light meters calibrated differently (to underexpose). Camera makers do this in order to protect highlights. The amount of underexposure is different between camera brand and camera models and the result is that the user believes that camera A can recover more HL than camera B.

The highlight DR range is the same for all digital cameras old or new, large sensor or small sensor. The difference in DR in digital cameras is only in the shadows. There is often a misconception on this because people tend to confuse camera lightmeter calibration to highlight DR range.

Mateus1: I like Nikon menu, one of the best. Pentax is also good, Fuji also. Only Sony's sucks.

Please add to those that suck Olympus too :)

Smaug01: That photo that won 1st place is pretty poor on its own. But the story behind it makes it so much more powerful.

Nevertheless, I think 'China's Coal Addiction' is better. It would've worked well as a B&W too.

That's the problem with photography. A photograph cannot tell anything on it's own. It cannot tell the specific story. Text adds the story. Remove text and you have nothing. I don't see the point of photojournalism in general. Write powerful text and leave the poor photography alone please.

On article In Fine Detail: Canon EOS 5DS / 5DS R In-Depth Review (746 comments in total)

The review is partially complete IMO. You are giving too much weight on the sensor, DR, AF performance and you are completely omitting other important aspects of the camera. This camera and it's rivals (D8xx. A7, etc) are going to replace medium format cameras for tripod work. Where is the viewfinder review? Is there some framing aids for square aspect ratio for example?

"rather than JPEGs created from Raw files"
yes but every JPEG is a product of RAW data. Even in the most basic and old digital camera or phone. Isn't it an oxymoron?

xoio: This is my favourite portrait by her... Ellen Terry
http://upload.wikimedia.org/wikipedia/commons/0/0e/Julia_Margaret_Cameron_(British,_born_India_-_Ellen_Terry_at_Age_Sixteen_-_Google_Art_Project.jpg

Does anyone know what camera(s) / lenses specifically Julia used?

This is an interesting photograph.
From a small J.P.Getty In Focus series book on Cameron I have:
This version is a mirrored version of the original Cameron shot at 1864 were the wall is on the right side. The original is wider oval shaped and is damaged at the lower center were the collodion emulsion peeled away from the glass plate. The negative was rephotographed later in a London studio with the damaged repaired. The mirrored version was published by Stieglitz in his Camera Work in 1915.
Unfortunately I cannot find any other technical information in this book :(

My favorite portrait, Beatrice:

Cameron is probably the first photographer in history with a body of work at such high level. In my eyes she one of the greatest. I wish I could visit the exhibition.

EvilTed: Underexposure and High ISO leads to more noise.
Awesome.
Thanks for enlightening us :)

What triangle? ISO is not part of exposure. Exposure is aperture and shutter speed only. ISO is a post processing step.

High ISO by itself doesn't lead to more noise. Underexposure does. The use of high ISO means that you uderexposing the sensor. Do you understand the difference?

panos_m: It seems that I will need a new operating system (64bit) also. As I read somewhere there is no 32bit version anymore :( True?

That's good news. Thanks. I suppose a clean install will be needed but that'is not a big problem. Thanks again.

I think also that the win 10 64bit free upgrade will be possible from 64bit win7 only and not from 32bit win 7, right?
