On Roger Cicala cynically re-defines photography article (54 comments in total)

Resolving Power:
Your ability to coerce the Professional Service division of your chosen camera/lens supplier to repair or replace your favorite sensor and lens combination and then explain exactly what they've done when they get around to returning it to you.
Theoretically constrained by the NightFedEx Limit, but in real world use, this level is rarely achieved.

Excellent news

I think they're just slightly different renderings of the same subject, one's the 'accurate' view according to current technology and the other has been re-interpreted to create a shift in meaning - towards what war photos are 'supposed' to look like - and those expectations are based on the renderings we got from mid-20th century lenses and film, Leitz, Nikkor and Kodak in particular.

This is an old debate and it's not deceitful to reinterpret color and light balance so long as you don't distort the meaning too much. It's more than twenty years ago we were changing the color of Kate Moss' eyes, using early Photoshop, so they matched better with the clothes and makeup she was wearing that day. She has fabulous eyes when you see them really close up.

On Accessory Review: Kata Digital Rucksack 467-DL article (48 comments in total)

Digital rucksack?

Now I understand, I've been doing it wrong for all these years using an analogue one.

And that looks like an OM1 there (maybe an OM2). Is there also room in that digital rucksack for a portable E6 lab and a scanner, along with a few rolls of film?

Hope you don't wear your camera rucksack whilst riding a bike, if you get spat off you can expect serious harm from your 5D Mark III continuing it's journey through your liver, kidneys, spleen etc...

Have a Happy New Year and enjoy driving safely.

At least this is fixable. I can't say I miss having to retouch film and prints with a Cotman 0000 paintbrush. Although retouching Kate Moss was kinda fun, even if it was on the Mac.

Thanks for doing that, smart approach to investigating the problem.

Looking at 0:43 to 0:51. Is that more like a liquid condensing than a lump of something getting sputtered on the sensor? As it's a time lapse we can imagine a slow deposit forming in each blob between shots and some of them appear to get bigger over time.

Maybe there's a volatile oil or similar, so it's evaporating from a nearby part and re-condensing on the sensor, rather than being slung around by the shutter or mirror assemblies. We'd then expect to find other (non-sensor) surfaces where the offending liquid would condense inside the camera too. Then Nikon change it to something with a lower volatility which won't evaporate.

We could test this with DP readers. Do people who DON'T get this happen to use their cameras in cold places?
And can we expect a DP Challenge for artistic pics of "Sensor crud"

In reply to:

bertibus: So if I pay a photographer to spend x hours over a period of x weeks to obtain a certain genre of photo(s) for me, I do not own the work that I have paid for? And he / she can use them (the photos) as they see fit, provided that I am also allowed to use them? Is that correct?

Photographer retains copyright, assigns a license to publish the work (probably with exclusive use) to the client.

this makes sense, a photographer could license a pic for use in print, or in a gallery, but not for unlimited online publication through the picture libraries.

It's a change that's consistent with how digital rights should be managed; i.e. separating the originators copyright from the distribution and publishing licenses.

duartix: 4K@60fps is impressive, although I can't think of any personal use for it for the next 5 years.

OTOH why isn't everyone talking about 240fps@HD which it is also capable of???

More info on the readout modes in here:

High frame rate is where it's at.

300 fps is better because it's a common multiple of 50 and 60, so global standardisation is possible.

I've seen R&D samples of 300 fps and it looks very special, because the picture refreshes so fast it's indistinguishable from reality (except for the parallax at short range).

On Sony Alpha SLT-A99 preview (326 comments in total)
In reply to:

Dan Ortego: Lately I’m bi-polar when it comes to cameras. I have gone from hitting the buy button for the D600/D800 and then the A99. Every time I read something else on-line about one over the other I’m then convinced it’s the one I want. Currently, I have the A900 and it just works! I also have a new 'blue-logo' lens for it so logic would suggest that I stay put.

The appearance of the A99 looks pretty aggressive to me, and I like it. If it handles and works better than the A900 while maintaining the ‘ease of use’ of the A900, then I’ll want it. The down side is that I don’t really trust Sony to support their gear like Nikon and Canon. Once you buy a Sony you’re pretty much on your own. It’s also hard to find a decent pro-level user forum since most of they’re following is a bunch of snot-nosed kids.

You could try taking a look at the pictures people make with each one. (DP Review / Flickr are good for this) and see whether Sony or Nikon look "better" to you.

I've got a colour calibrated monitor and I can see the differences between sensors and lenses from Sony, Nikon, Canon, Pentax, Olympus and the others. Arrange your screen to hide the metadata then play guess the camera.

Here are my subjective generalisations. For some reason, I just can't enjoy the full-frame Canon look, there's a blue-greyness to them that makes them look dull and lifeless. Nikon shots look pretty good to me. Sony Alphas all produce spectacular colours, especially in high contrast. Zeiss lenses give an image more life (except even they can't help a Canon).

Like you, I'm seriously tempted by the Sony A99, with Zeiss primes, but practicality (support, continuity, the used lens market) and a bag of Nikon glass says D800 or a D600 with a special something from Zeiss.

ProfHankD: Well, the price isn't bad for medium format + Leica branding, and the mostly ordinary feature set isn't that ordinary for medium format, but I wonder if IQ can beat the Nikon D800. Sadly for Leica, my guess is no.

for VivaLasVegas...
If you see Angelina with a big Leica it's one she got off Brad - after he replaced the one he had stolen.

Wood shouldn't appear on any camera smaller than 4"x5" format.

Direct link | Posted on Sep 18, 2012 at 16:56 UTC as 332nd comment

Is this a repeat of Sony-Ericsson, Sony does like Swedish brands (perhaps Sony-Ikea next? Ewww, no ! )

2) For a moment I thought they're going to make a baby-Blad with a square sensor and a smaller form-factor.

Franke & Heidecke did that with the Rollei and it put off the inevitable decline for a few more years...

Edymagno: It is an ugly camera indeed. Its all rounded contours almost all finishing in pointy profiles remind me so much of the GM Corvette prototypes of the 60's. This "socking" look is unnerving. Maybe one needs to acquire the taste. The 70's muscle car look with the high waistline is coming back.

If it's a pleasure device you're after, you might find boxy and pointy profiles isn't really going to work for you. Rounded contours do have their place.

In reply to:

vFunct: Sweet! I still have my hand-crank 8x10 polaroid film processor & view camera.. just need to buy back some lenses.

PROTIP: This is one of the few techniques one can use to create photos without any electricity. Large-format lenses have spring shutters, and the Polaroid film can be processed by hand-cranking!

Not strictly true about the zero electricity, because your hand-held Weston light meter generates a tiny amount of electricity from its selenium photocell, just enough to drive the moving coil attached to the meter needle the correct distance across the (analogue) dial.

Here's one.

I learned about light with one of these. Absolutely excellent when using Ansel Adams' zone system for controlling exposure.

davidkachel: WOW!
T-Rex is dead!
Does this mean all Kodak camera films are done? I guess so.
This may go down in history as the biggest mismanagement case ever.
After all, photography is not dead, just Kodak.

It was Tri-X not T-Rex, but I like your name for that classic mono film much better :-)

Dan Nikon: Both still and motion stocks are made in Building 38 so how can they separate them? Well, who is to say that Kodak is not selling both lines to the still film buyer only to lease the line back when needing to make motion stock? And who is to say that a big, big player in the motion picture industry is not going to buy the stills division and then make, sell and distribute both motion and still stock, even if for a few more years until MP film is no longer viable.

There is still good profit to be made on Kodak film, even the still version. A lot of pros like my self have re-employed the use of it in niche projects and especially fine art where the price of a real silver gelatin print from real talent just keeps going up and up. I have personally invested over 30K in film, paper and chemistry in the past few years because after using digital for 20 years, I can not live in a world where that is the only choice of medium I have to use.

This is not over yet, lets see what happens..

Hope Kodak material stays in production. I saw the Travel Photographer of the Year exhibition in London yesterday, 16x20" colour prints. The content was excellent, well worth a visit, but the technical quality of large prints from digital was shockingly bad. Poor colour, contrast, edge artefacts, various optical aberrations and all with much lower resolution than Kodak film. These were shot with top-end cameras and lenses, Canon full-frame mostly (why do Canon pics have a grey cast?), a few Nikons in FX and DX sizes and the odd Sony alpha. The Hasselblad H2 wasn't much better. Honestly, an Olympus OM2 with the 35mm and 85mm f2 Zuiko lenses and a pocketful of Ektachrome did better large prints for travel and landscapes. A 180mm for "long" shots - could always crop from that later. That setup probably weighed less than a DSLR too, and it still worked in sub-zero temperatures. Have we really gone so far backwards on quality in the name of "convenience" and "automation"?

km25: Sorry but, the technology is new in that one may do so easly. But the idea dates back to someone, I cannot recall his name. But he used multi cameras trip wires to prove how horses real ran, their gate. But to do so easly is real amazing. You also can do it with a low level room light and strobs, single fram, multi strob flashs. I did not read all the comments, if someone else has already stated this, sorry.

malcolm82: From Engadget:
"Ultimately, there's plenty of reason to believe the BBC's project head, Tim Plyming, when he says that "8K is the maximum the human eye can understand" and that "it's the end of the resolution story.""

That's only true for a field of view equivalent to about 40mm (or about 55-60° diagonal). For ultra wide angle viewing we need much higher.

Tim has a point about resolution, but that's not quite the end of improving the moving image.
Frame rate is highly significant.
In parallel with working with NHK on the 8K Super HiVision, BBC R&D experimented with higher frame rates.
We know that interpolating frames into a 50 or 60 fps video for motion blur gives artefacts and a slightly weird look, but native 300 fps (6 or 5 times faster, depending) updates quicker than human vision can distinguish from reality. I've seen their demos and a very odd thing happens. The picture suddenly looks much more "real", it has a clarity of movement that is magical. It's like looking through a window or being there in person. The BBC has a demonstration of a game of table tennis that shows this perfectly. The improvement is most obvious in fast moving balls and in facial expressions.
The data processing for this is (of course) fearsome, but it is a worthy avenue of improvement for video.

Vegasus: Hi Guys.... Finally... SLR with " WIFI " system... but.. why attach to the side? Good Idea but not convenience ... but good enough. I like the WIFI system. Good Job.

Separate unit because WiFi specs vary by region. For example, the channel 14 frequency is forbidden in UK but can be used in US and JP. So if it's internal the camera needs to know where it is - integrated with GPS perhaps?
