May we all see like insects: light fields and plenoptic lenses. There could well be an interesting shift in specialised photography where extracting 3D data from digital images shot with either special lenses or sensors (and with a lot of post-processing/number crunching) become useful tools for VFX practitioners.

(Full disclosure: like most people, I’ve had a lenticular fascination since I was a kid. I just didn’t know what to call it…)

Now, of the technology, the immediate, demonstrated applications are variable focus (in post); or the ability to move the camera and change perspective within about a 10° arc. While this is something readily achievable in a layered composite, the implications of it being readily available and nicely packaged with a bow are quite interesting (see: focus stacking, helicon focus). And, if (if!) it can be applied to moving images, then there would depth information that you could use to extract layers. That is, you wouldn’t have to pull a key; you could go without green-screen; rotoscoping would be easy… oh, the possibilities… Okay, I’m getting way ahead of the technology.

But then, beyond the “3D” hype, there have been a lot of recent, significant developments in sensor technology, such as the Panasonic high dynamic range sensor… and even the CIA is hocking its image technology. Yes, the Central Intelligence Agency. Insert your conspiracy theories here. How about the Gigapan $300 (?) photo-robot…

While we may wait for a new digital camera in the coming months, we should probably bear in mind that Moore’s Law can be applied to digital photography and cinematography…

It is interesting when you are scouring on the web for the newest thing™—be it the RED camera, or anything else—that so many reviews are now done by new owners writing on their own blogs. Some of them write excellent appraisals, some of them don’t. “Traditional media” reviews can be much the same; but usually more space limited in publication, so they are not as in-depth or obsessional as the non-traditional media. The key difference between mainstream reviewers and bloggers is that they don’t actually own the thing they are reviewing. Bloggers usually have used their own money.

So when you read blogs about the latest big thing, in my case recently, the Sigma DP1, you are usually getting the opinion of someone who really, really wants this thing to be good. Even if it is not.

The DP1 looks like a marvel on paper. The (Foveon) sensor is giant-sized amongst its rivals, which means it should be less noisy, and have better dynamic range than most. By all accounts, it seems to. The optics seem reasonable. It is quite a capable camera. People are comparing them to SLRs, and suggesting the DP1 is more like an “affordable” digital rangefinder. The wheels start to wobble when you find out that the focal distance (minimum 16cm) is quite limited and the lens is only f/4.0—especially when compared to rival cameras. Image-wise, it should be better than its rivals, but it doesn’t seem to be significantly better, and new images would suggest that it is amazingly better. But some things are pretty disappointing, like the very slow write times. Up to 12 seconds a shot… perhaps less with a faster card.

But everyone wants it to be good.

Enter Carl Rytterfalk, blogger. You can’t say that he isn’t enthusiastic about the DP1. His posts cover a range of excitement, disappointment, workarounds, and excitement again. Luckily, he is posting informative stuff on the camera… and some entertaining videos (he also blogs about the Sigma SD14, similar sensor but in an SLR body). The nice thing about his reviews are that he is unapologetic in his enthusiasm, but he doesn’t ignore the problems:


Btw, as someone said at the forum already – turning off quick preview makes the DP1 faster between shots. And I also tested a normal SD card that came with another camera – it’s SOOOO SLOW! It really takes ages. So please. Use fastest card you can find, it’s a huge difference!

Timed save times RAW (light blinking):

SanDisk Extreme III 4GB: 2.5s

Canon SD SDC 32MB: 10s

Time before you can take another shot (single mode): 3.8s and quick preview off.

If you look at his site, you’ll see he’s thorough. He even compares it (somewhat tenuously) to the RED Mysterium sensor.

It is also worth considering that so-called “bloggers” could be paid shills for whatever company they are promoting. Ever wondered how some of these guys get their hands on stuff way before everyone else? On the other hand, now that bloggers “get there first” with reviews, you have to wonder at the number of posts that are less to do with reviewing and more about soothing buyers regret. People like Carl Rytterfalk, excepted.

And the camera? Its quirks guarantee it will be a cult hit.

I was wondering when this would happen, while there have already been a few, this auction is for a “soon to ship” RED One body (the idea being you can skip the waiting list… a bit like those people that stand in line for you at Disneyland!) Check it out here. One day to go…

200803131020.jpg While I stand in my kitchen, sipping my morning coffee, a couple of junkies outside are locked in the slowest verbal jousting I have ever heard. Each side seems to take a little nap between responses… I hope they finish before noon.

They probably wouldn’t be arguing if only they knew that details of the Canon 5D MkII have been leaked/rumoured/invented at the Digital Photography Review forums (and further comment here). Supposedly there will be an official announcement April 22.

Features (allegedly) include:

  • A new full-frame sensor with fancier noise reduction
  • Weather sealing like the 1D series
  • 15.3 MP
  • ISO 12800 (hmmm)
  • Micro lens fine adjustment
  • EOS Integrated Cleaning System
  • Live View (meh!)
  • 6/3 fps continuous shooting for up to 68 frames
  • MSRP $3499 USD, available June 2

This covers my wishlist, so much so, I am willing to believe. Anyway, it must be true, I read it on an internet chat forum. It does seem like a plausible response to the excellent Nikon D3 – what a happy day for digital SLR-ists.

I think the junkies outside must have heard. Argument finished.

I’m about due for a new digital SLR. My old one, a Canon 20D works perfectly, but we have, uh, grown apart. Things were going swimmingly, until I bought a mint-condition “used” Canon EOS 3 from Map Camera in Tokyo. Remarkably, it is still on the Canon Australia website for AUD $2,199.00. Mine cost AUD $300.

eos 3_angle shot.jpgI assume the 85% discount was due to it being an “analogue” camera, you know, like the old days. And who the hell would want one of those? Seeing as I had sold my last film camera to a DOP I know, and put my hand on my heart, grandly declaring that I would never go back to film. I have had to step back. Mea culpa.

There are many things to love about the EOS 3—from the quirky to the sublime. Quirky is the eye-controlled focus, which actually does kind-of work. Sublime is the weight and balance, the full-sized viewfinder, the speed of the autofocus, and that satisfying whir of film rolling on—and the full sized, er, “sensor”.

Just down the lane in from Map Camera, Shinjuku, is the remarkably well stocked film department of Yodobashi Camera. I got just about one of everything, feeling oh-so-smug when I calculated the number of exposures I could afford to buy with the money saved not buying a new digital camera.

I wasted no time loading that sucker up and popping off a volley of exposures. Compared to the 20D, things just looked better through the eyepiece. It was brighter, bigger, and the lenses behaved as they should; not cropped to 65% of their field of view by an awkwardly sized sensor. I was in love with a camera all over again. Our love, however, was a bit one way. Being film, I had no idea if the camera loved me. There was no digital preview. However, the funny thing about shooting digital for a few years was that I think it trained me. You would think it would make you more lazy, more dependant on that little screen on the back. I think the opposite was true, I learnt so much about exposure and making quick choices—consequently, my “guesses” became more accurate “estimates”.

After ripping through about 12 rolls over the next few days, I took them to be processed. I would have been surprised if there was a light leak, scratches, or other camera-bound problems. Although second-hand, the camera was still in its factory-issued plastic bag and it still smelled modestly perfumed by some carcinogenic plastic polish. The manual was fresh, with warranty card inside and a little cheat-sheet sticker to decrypt the cryptic “user functions”, represented only by numbers: it was all intact.

kyoto night taxi 2 When the film-lab passed everything back over the counter and switched on the lightbox, I got excited. I thought it all looked pretty much what I had imagined it to. Although I had no idea what the negative actually looked like, there were no incredibly bright or dark bits on the film (so I guess exposure was in range), and the little digital contact sheet seemed to indicate everything was okay. The reversal, on the other hand, was a more direct, easy to read result. And I was very happy with the way it looked. In fact, I couldn’t have been happier. Scanning them would be time consuming, but I though it was worth it. They were on film, dammit. They just felt–I knew—less transient compared to the digital versions, which were rather venerable pixels on a hard disk.

The the smile was wiped of my dial, of course, at the cash register. I’d forgotten just how much it costs to develop film, worse still, I hadn’t factored it into my utopian calculations of film versus a new digital camera. A quick thumbnail calculation (now much rehearsed and revisited), pretty much blew my first theory sky high. It wasn’t cheaper. It was a lot more expensive. Later, as I was waiting for the slide-scanner to finish previewing a scan… I realised the cost in time. I hadn’t even got the shot into a state I liked yet! I could die before the scanner finished! Or at least finish the bottle of wine that was tutoring me…

So this all served to remind me of why digital was so seductive in the first place. However, that first, naïve digital love had now been replaced by something more mature… more… experienced. I dared to look back, and lo, it hath spoilt me. Now I wanted the best of both worlds.

Lush My 20D has problems that really irritate me. It’s okay, I promise not to get angry. First, and foremost, is the sensor crop. I hate it. Note: next digital camera will not have this problem. Second, is dust on the sensor. Whatever I have done, no amount of electrostatic, gently blown air, wipes, or chanted incantations will get this crap off. I’ve resigned myself to the fact it is probably there forever. Note: next digital camera will have an anti-dust function (as is appearing in quite a few these days). Third, is the viewfinder—there’s not enough information, it’s too small, and too dark. To constantly have to consult the camera LCD bugs me.

You see, we have grown apart. There was a time when the 20D felt like raw power in my hands. Now I am looking further afield. I’m sorry 20D… I think we need some time apart.

on the path Anyway, as you have probably guessed, the reason I am “waiting for the man”, is because what I want isn’t available yet. Like any good technology junky I don’t think I am ready to compromise. I’ve done that. I want what is going to fit. So as much as a Canon 5D is tempting, and ticks almost all of the boxes, I also know that the new version is imminent. My suspicion is that this new version should be exactly what I want. Unfortunately, it has been rumoured to imminent for about two years, and despite the reports suggesting that Canon were going to lay one in January at the PMA, it didn’t materialise. Pundits now have it marked for August. But that’s not all: now there are suggestions that there will be two cameras in that bracket. The 5D MkII; and—allow me to suppress my absolute joy—a digital version of the EOS 3, the 3D. After all I have been through, could it be true? I have no idea, they are rumours after all. But now I do know what I want, and I am not spending another cent on a digital SLR until I get it.

I may however, have to spend some more on film… until it arrives.
