Just Ed: 1,3,6 and 7 seem the best to me. 8 makes no sense as a fine photograph...possibly I am missing something

I guess the author's intention was to depict a stark contrast by sandwiching the gorgeous garden patch between both human-made "forced" colors and asphalt gray.

ChuckTa: I looked at the full size photo of the Japanese man in outdoor and I see a greenish outline to the right side of the face down to the neck and suit. Is that CA but green colored?

What if we put "pretty wide range" in perspective?
We're looking at a 7,360-pixel _w_i_d_e_ sample, mind you... (a whole 36Mp a7r shot)

Please take a 2nd look, it's the regular longitudinal CA we all know and abhor. The purple component is right there, only much less conspicuous; look at (his) left side of the hair, above the glasses.
Wouldn't you say it's a relatively well-controlled CA, though?

"...Canon has reverted to using a *sensible* + on top, - below' labeling for this [exposure compensation] dial after confusing us thoroughly..."
To me it's just the OPPOSITE as I tend to associate it with a volume control, so it's rather counter-intuitive to turn it COUNTER-clock wise to INcrease exposure. OK, maybe I should start associating it with an old-fashioned rotary faucet...

PerL: Is the image on top a fake? Othwerwise it looks very compact - very interesting. Imagine a FF DSLR the size of a 70s SLR.

"an FF dslr the size of a 70's slr"... like their own 1976 pentax ME, wow!!

In reply to:

nerd2: One fun fact - guess who made the first FF DSLR? It's Contax.

Another fun fact: the first autofocus interchangeable lens *SLR* was by Pentax, 1981. A bit of history here,
http://en.wikipedia.org/wiki/Pentax_ME_F
(The futuristic 1972 Polaroid SX70 was a fixed-lens SLR.)

On 3,200MP LSST camera gets construction approval article (257 comments in total)
In reply to:

RichRMA: Is this constructed using CCD's and not CMOS? I seem to remember someone saying that CMOS lacked "Something" which is why they don't use them in most science projects.

Probably a broader spectral response, near-IR to UV considered. Just a hunch.

King Penguin: Quality, quality, quality........mmmm, I wonder if any of these photographic winners have posted a dis on DPR about a camera they didn't use because it's shutter speed only went to 4000th of a sec..........

@b craw,
I'm not sure it's the same photo we're talking about.

Nevertheless, if it's indeed tjhe same, would you be so kind as to point out some demonstration of "unsophisticated method" or some "formal decision in favor of restricted use of DR" in photo 11, "Sichuan Opera, The Leading Actress. Photo by Haixing Liu (China)" ?

I believe that not every accomplished photographer is gear-oblivious. Case in point, it looks like the author of "Joie de Vivre" (the horse) likes fast shutters; the tips of the hairs of the mane and the tail look frozen in air.
And, on other technicalities, one staple discussion here (more often than not scoffed at as pointless) is about sensor DR, especially across brands. I wonder, though, if the author of Leading Actress/photo 11 would settle for a so-so sensor? (No crushed shadows, nothing miserably blown next to the light bulb... yet probably shot at a high ISO.)
So yes, there is a possibility that they are around here right now bitching & bickering about shutter shock, compressed RAW, equivalence...

On Canon 7D mirror box filmed at 10,000fps article (174 comments in total)
In reply to:

FRANCISQUAN: I'm just amazed that the Canon 7D mirror box can film at 10,000fps yet Nikon struggle with their flare ridden 6.5 fps full frame camera.

I guess Canon is the way to go for the newer technologies like 4K..

It's not only the 7D mirror box; actually, there are many, many things that can be filmed @ 10,000 fps to be better undestood. Nikon FF mirror boxes, bullets ripping thru apples, H-bomb deflagrations...

On Canon's Q4 earnings report shows camera sales are down article (315 comments in total)

Would'nt
"Canon's Q4 report shows THEIR camera sales are down"
be a more, err... journalistically correct headline?

Roland Karlsson: The biggest question is - is there an alpha channel? I.e., can you make "real" tattoos where the skin is visible?

An Exacto knife will do.

In reply to:

RichRMA: We've gotten to the point where computer design, and other innovations in lens manufacturing should allow what used to produce horrible results (add-on lenses) to produce respectable images today. Vignetting on macros is no big problem since most macros rarely include the whole field of view anyway.

No one said there would be a vignetting issue "on macros".
What's written on the copy is
"when used at normal focus distances with the larger format",
which in turn was condensed from the manufacturer's FAQ,
"you can use this lens in Full Frame Camera. Everything can work EXCEPT you will get slight vignetting during infinity focus."

Karl Summers: No EXIF data?

Whereas pretty much like everyone else I don't' like to think myself as a Luddite, DDemolder's witty "notebook" comment makes me wonder how much of our cherished EXIF data will survive 152½ years in the future!

In reply to:

wherearemyshorts: all that money for the camera as shown in the photo and it is possible to still see the 2 screws holding the grip to the body.

not well done at all

a great reason to close the facility

Some like double-sided adhesive tape better.

Marty4650: I wonder if Hassleblad finally realized what all the laughter was about?

Of course, the real joke is on anyone who spent $8,000 to buy a Sony NEX-7 dressed up in a Hassleblad suit.

A "Hassleblad" (or Hasslebadly) SUIT?? Please don't give'em ideas, else we'are all doomed to see "Hasselblad authentic-turtle shell rimmed google glasses"!)

This Spencer guy is witty. "What we have here is the world's first 23mm f/1.7-2.8 lens" is priceless...

steelhead3: Dell has a 31.5"4k monitor with all of the goodies mentioned for less than $1600 on Amazon.

Got reasons to suspect that when steelhead3 mentioned a 31"/$1600 monitor he was thinking about a wide-gamut panel to be put on his desk, not on the back his camera.
