Not so much your feet, but your hand that holds the camera!

Excellent article . . . thanks for posting this DPR.

Richard Kwon: I hope she okayed the last picture... Most models do not like to see every single detail in their face... I hope she gave the ok to post it...

Hmm, I think seeing the details in her face makes her real instead of a surreal photoshopped plastic faced doll as most models want to look/are made to look these days. Nothing sexier than seeing the tiny real details in a beautiful woman's face.

Ah, another misleading headline from DPR . . .
You are (or should be) paying a different price for the other stuff:
- Quality of the machining and material
- Multiple coatings, scratch resistance, cleaning/water beading, etc.
- Total light loss to get that polarizing effect
- etc.
So it's just not that simple, though Roger focused on the how "well" it polarized, which is a pretty easy thing to do well.

Some cheap CPLs I've found to degrade the image quality due to coatings, glass non-flatness, polarizing film used, or whatever.

Always entertaining nonetheless when Roger writes about something!

ojos azules: Top 10 signs Nikon is hurt by Sony.

1: nikon plans for FF Mirrorless.
2;....

2: People like me bought Sony mirrorless gear instead of Nikon DSLR gear.
I bought an A7RII, Sony 85/1.8, and Sony 35/2.8 instead of any Nikon gear in the last 3 years. I.e., Nikon got none of my $$ since I bought a D800 a long time ago and my excellent condition AFS Nikon lenses will soon be sold to someone who could have bought them new from Nikon instead, thus also missing out on $$ they could have gotten.

And the sensor in Nikon's first FX mirroless will be the same as used in the D850 since it already has:
- On sensor PDAF
- Electronic Shutter
- ~46 MP
- BSI

It took you that long Nikon to state the obvious?

photoaddict: I cannot understand the appeal of mirror-less camera. I find it very unnatural to use. I like using optical viewfinder. I like looking through it. I hate looking at the LCD screen or EVF. It looks awkward and doesn't give you what you want to see.

I can see the size being smaller as a nice bonus but.... other than that, whats the reason for it?

Dude, you must be hiding under a rock for the last 5 years to not know of any of the advantages (and disadvantages) of a mirrorless, interchangeable lens camera.

Go rent an A7RII and 85/1.8 for week and I think your mind might be changed.

jhinkey: Is it just me or is there less magenta in the mid-tones of the ISO 64+6EV D850 image?
My biggest issues with raising shadows is the magenta tone that becomes prevalent in my D800. If the D850 can be that good at ISO64+6EV then I think I'm sold.

Yes, but you generally screw up other colors in the process of trying to fix this, so not having it (or having it minimized) in the first place is the way to go.

In the (not so distant) future you will be able to have small drones with modeling and flashes attached to them that hover around the photographer and subject, all sync'd together to flash, etc., thus negating the need for one big flash like this on the camera.

Looks cool though.

jhinkey: Any idea of the actual flash duration - 1/8000 sec shutter speed sync doesn't actually say how fast the actual duration is. Could not find it in their technical info section.

A Nikon Speed Light at lowest power has a very short duration flash of 20 microseconds or so if I recall, which was too long for one of my recent photo applications (so I built my own, 5 micro sec flash, which was a pain).
If this flash can to 10 microseconds or less with a pretty reasonable shape to the light curve I'd be very happy.

K E Hoffman: As someone who was there just miles from where this was taken. This video does not even capture the experience. Heck the exposure was not even corrected well enough to capture what as a spectacular corona this time. I like seeing the prominences but I can see those in still shots.
This for me is a case of too much gear not enough art. It isolated a spectacular and very emotional event for many into data collection.

Harsh. The video captures what the vast majority of people did not see with their eyes. Using my 600mm + 1.4TC + solar filter I had a live view feed on a screen that people could see and they loved it since they couldn't see much detail with their eyes using a solar filter.
What I find really nice about this video is that it captures just before and just after totality so you can see what that looks like in real time - not something you can see with your eyes (even looking through a lens) or with still images.

falconeyes: Overall, I very much like this video and the circular motion around the sun's circimference. But the effective resolution is FullHD at best, no need to make this 4k. A better use of 4k would have been a wider angle, also better capturing the moment, I guess.

Moreover, I heard the corona was much wider than captured in this video. An s-log video color-graded to show it all would have been appreciated (by me).

s-log would not have shown it all. To get a large extent of the corona with 14 bits of DR still requires the prominences to be way over-exposed.

steelhead3: I am surprised that smoke from all the fires didn't get in the way...fires burned right up to Ka-nee-ta on the Warm Springs Reservation (completely rented out to a Japanese group)

The wind was favorable that day in Oregon. I was East of Warm Springs near the Idaho border and there was a faint faint haze still present, but it didn't cause any real imaging problems. We lucked out that smoke and clouds cleared out for the big event.

Very very nice. Having photographed the eclipse myself (both with and without filters) I know how not easy this is to do.

Link | Posted on Sep 5, 2017 at 16:57 UTC as 18th comment

This being my first eclipse I was afraid of frying my D800 or A7RII, but being an engineer I did the math, did the research and got the right filters (made my own from stock filter parts actually to custom fit my tele lenses). Still, when the eclipse ended I had to be fast to cover up the naked 400mm + A7RII that took awesome images during totality. The 600mm had aperture mask + IRND filters the whole time.

Looking forward to the next eclipse using even better gear.

What's missing from the article are images that illustrate what's being said in words and charts, as that's what most of us see from our photographic devices.

Link | Posted on Sep 1, 2017 at 15:02 UTC as 87th comment

Sure in some cases going from 12 to 14 bit, even at high ISO, just resolves the noise in the shadows, but typically the shadows are lifted a lot and the highlights are pulled back down. The result is more natural shadow noise (less clumpiness/banding) and less banding in general.

If you don't need to make drastic post-processing changes to the shadows and highlights then 12 bit tends to be just fine.
