"Raping the Internet has never been so easy!"

How is this any different from downloading the CC images and printing them? Not very different at all.

As for these images competing with "fine art" photographers - how? Not everything that is CC is something you'd want a poster print of. e.g.

And to be honest, the difference between "artist" and the rest of us is time and money.

On Light Field Cameras - Focusing on the Future article (135 comments in total)

The silly physical design of the camera betrays the struggle to differentiate it from "normal" cameras.

Consumers do not care HOW the camera arrives at "focus as a afterthought." The way the Lytro does it is unimportant to consumers. Most people use phone cameras, so they will not be a Lytro customers.

The market for such a camera is therefor "true believers" - which does not bode well.

In reply to:

Mark Banas: It seems to accept, and trust, falsified EXIF info (via EXIFtool) with no problem, so my Pentax K-5 must actually be a 16MP Nikon D800? Not terribly sophisticated service...

If I stand where Ansel Adams stood, take the exact same shot, and do the same PP in the dark room, can I sell it as an Ansel Adams? Because that's the argument... Provenance matters, so by extension the EXIF matters.

In reply to:

Marky boy: who cares.... really....we like what we like, regardless of how, what and where. We can tie ourselves up in knots about post processing, however, it is no different to darkroom skills of old......

The value to this goes beyond the trivial use of determining if the supermodels eyebrows were digitally waxed. It could easily establish forgeries, and settle ownership issues. Furthermore, a system could be constructed to create a certificate chain like verification mechanism that would establish derived works. So photo B is an edited version of photo A, but B's crypto gobbledygook is chained to A's.

PKI + EXIF

Yes and no. Film and the camera it was shot in could be examined by an expert and one could conclusively determine if it was faked. But the negative would provide a level of repudiation against a modified print.

The digital negative has no non-repudiation mechanism. So its inherently NOT the same. Security logs on truely secure systems will have a non-repudiation mechanism, usually a cryptographic checksum.

In the context of a camera, the camera would use a private key to sign / encrypt the cryptographic checksum of the image data. ( The signatory agent could also be a wifi attached service, so some other mechanism. ) Then should someone need to validate the digital negative they need only decrypt the checksum value with the cameras public key. The checksum can be verified against the image data, and you have verified that this particular camera took that particular negative.

On Is it true? New service detects processed photos article (88 comments in total)

I'd love to have access to the original test images. Its super easy to tell if an image has been edited - even expertly - as each layer of edits has its own signature.

Perhaps DPR should have a "Is It Fake?" challenge with 10 pictures, and see if we, as human beings, are better than the soul-less cloudy-cloud. We fill out a true / false form for each and whoever gets it right is put in a pool to win something.

EXIF data does not contain a non-repudiation mechanism and can be forged easily. Its a bad litmus test for both real and fake photos.

Luminance noise is the sort of noise we experience in nature ( haze, fog, smoke, dust ) and in film grain, and in our own eyes when its dark. Chroma noise is abrasive, unnatural looking, and distracting. There is a difference between us being physiologically more sensitive in our ability to detect something and it being horribly distracting.

Would you rather listen to a loud pounding rain -OR- a baby's desperate, spasmodic crying at half the volume?

In reply to:

jonny1976: The beauty of medium format is ccd. Thats what create the magic. Whats the use of a camera that creates the same d800 IMAGES with more pixel? Which professional will use a blad at iso 1600or 3200? The blad, not like pentax645d, is not Made for street.

I think your prejudices for or against CCD vs CMOS are based on old info, or no info. Both can very competently capture an image. The highest DR sensors currently in production are all CMOS sensors. Because of newer fab methods CMOS is less expensive to produce in larger die sizes than was one possible. And the fab techniques scale up and down in size. In a sense your were using CCD because that's what they could make, not because it was inherently better. Even your $40K hassy rig is "value managed."

On In photos: The beauty of bees article (49 comments in total)
In reply to:

Biowizard: Sorry, but as a biologist who loves and does everything he can to support the dwindling natural environment in which we all have a deep and profound share, I find an album of photos of collected-and-killed bees about as appetising as those dreadful cases of pinned, dead (some now extinct) butterflies, moths and beetles collected by Victorian "explorers".

Not impressed.

Brian

I'm right there with you, BioWizard! Appreciating these photos is much like "appreciating" a lush studio shot of Marilyn Monroe's corpse.

When I saw the DPR teaser shot, I said "Wow! How did they get shots of bees in flight like that?" I was prepared to learn a cool new technique or something. Then the anti-climactic answer: Dead bee + $10K of publicly funded camera gear and time.

The researcher is free to follow their bliss. I'm not critiquing the work. But rather DPR's highlighting these mortuary shots. How about an article on someone dealign with live insects, using equipment most of us have?

I do a lot of ( non publicly funded ) macro work, including super-high resolution / zoomable images of ( non-deceased ) bugs, e.g. ( http://maps.muhlenberg.edu/iip2b/moth.html )

On Backstory of Phantom Flex4K video shot at 1,000 FPS article (91 comments in total)
In reply to:

BobORama: So its a $140K camera system that makes even the most exciting jobs look boring? OK, the slo-mo flames are nice, beautiful, and the water emerging from the nozzles was interesting.

I guess the REAL advantage is that you can shoot a scene at 1000FPS and then in post production get whatever frame rate you desire to achieve. Smooth adjustments in the time scale give you very cool effects. And if you were shooting Inception 2 - it might be useful.

The scene does underscore how much water is entirely wasted. 80% of it forms huge globules that never actually participate in putting the fire out. One of the profs I had years ago was involved in alternative systems and things like a pressure washer, or even steam put out a fire more effectively, and with so little water its truly amazing.

If you can put out a fire with 80% less water, you downsize every aspect of operation, from the tankers, trucks, ... the need for hydrants. Also less water means less water damage.

thx2238,

By your standards I've never had a single glass of "American Beer" But there are a lot of fantastic beers made in the USA. And if not beer, Laprhoaig?

And as to By Gediminas 8 concern... I would only take issue if you drink your beer through a straw. And after a few, I'd probably overlook that as well.

MrTaikitso: Reading the comments below this outstanding piece of cinematography provides further evidence of how somehow, DPreview's 'readership' has altered from calm intelligent professionals and prosumers to imaginationless unintelligent types who are either too young or otherwise inappropriate for a forum like this.

To call the slow motion 'boring' when in fact it superbly conveys the resolution as well as providing the viewer more time to take in what is going on. No doubt, unboring would be human carnage and exploding cars. For that, suggest you try another site or DPreview needs to up it's game when deciding who should be able to signup and comment. Now I know why membership only clubs exists, to maintain a level of decorum.

Amazing film and a great showcase for what the sort of quality we'll be watching at home by the holidays 2015.

Under The Sun,

I'm not willing to be labeled by the self apointed intellectual / aesthetics elite as one of the "imaginationless unintelligent types." I'll put my cat photos up against his cat photos any day of the week.

Thanks for your ad hominem attack on the rest of us slobs. But its squarely a technical achievement, both for the Phantom and for the DP and crew what had to figure out how to make the beast happy, rather than a cinematic one. Its an ad for the Phantom rather than the next Citizen Kane. There are some beautiful bits, for sure. But what you ask is for us to confuse marketing with art, and this seems to have much more to do with creating a vehicle for showcasing the Phantom than telling a story.

Depends on the party.

We should rent the camera and make an epic 120 minute version of us drinking a beer. Just image it, 2 minutes of a single bubble evolving at the bottom of the glass and slowly rising, engorging, and finally bursting forth from the quiet surface of the glass.

In reply to:

BobORama: In terms of C&C, I think this is an example of the "soft bigotry of low expectations." Its interesting to see Forrest's creative process in action:

http://www.youtube.com/watch?v=-lMrTvMo_y0

Which seems to be pressing the shutter without aiming the camera. I suspect a lot of the "art" is in the judicious parental selection of the good shots.

I am very leery of facilitated communication techniques, as over the past 20 years, a series of these techniques have emerged and been thoroughly debunked. Rapid prompting is the latest incarnation of FC. That dad leads / anticipates the completion of words, and moves the stencils, hints at facilitator effect. I have no idea what the situation is for Forrest, hopefully I'm wrong.

In previous incarnations of facilitated communication, the child is turned into a biological Ouija board, which the parent unconsciously operates. And most parents don't care if it really works or not, as long as they believe it does.

Marshall and AMB Barry,

Neither of you have bothered to post an avatar, so you deprive me of the opportunity to look into your soul.

I believe you missed the point entirely, and if you were more informed about dark history of facilitated communication and the lack of credible evidence that rapid prompting actually works you would take my post in the spirit it was intended.

In other words, if you had skin in the game you might view this with the healthy skepticism that helps protect the interest of vulnerable individuals. FC is insidious, and its damaging. Learn something about it.

There are really only two ways to view this piece: subconscious, unintentional, and subtle exploitation -or- a triumph over ones disabilities. The distinction is critical.

Believe me, I want the Disney ending too. But having seen the damage done by the last 20 years of RPM's discredited predecessors, I can't view this as the rainbows and unicorns feel good fluff piece DPR hoped for.

On Sigma USB Dock quick review article (139 comments in total)

All they need to do is put a sensor in it ( and a KAF mount on the front ) and you have a product I'd buy. I would love for someone to create an easily integrated imaging system - free of legacy SLR design constraints - that you could use for projects, research, machine vision. Either that or a standard, robust way to expose the control surface of the tyoical camera via USB or WiFi in a way that makes it easy to integrate with mobile devices, or whatever. None of this is hard to do. But Japan seems stuck in the 1970's regarding what a camera is, and what we are supposed to be doing with it.
