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.

If you were wondering about (digital) exposure, you could do worse than this excellent run-down by Stu Maschwitz, with some log theory to boot. If you were ever wondering why video and film are so different this is a good start… Ignore all references to the RED camera and REC709, though, as it tends to muddle the threory.

Conclusion: they may not be film cameras, but they are definitely not a video camera. READ

EDIT: Having read the the subsequent furore over Stu’s article, and the comments at reduser.net, it looks like the digital film-scanning arguments of 15 years ago. Some people dig the theory, yet in other, analogue worlds, it doesn’t seem to be a requirement to know how to make a strip of film all by yourself, despite the fact that film is integral to the process.

Digital doesn’t have to be technical beyond a few basic rules. It would be a shame if everyone thought a RED camera had to arrive on set with a “technician”, like the Genesis does…

Fear, uncertainty, and doubt. I think some people are inventing jobs for themselves. Commercial photographers that have gone digital would have a giggle at some of the comments.

We were the main VFX vendor for a reasonably budgeted VFX film. One of the major sequences we did was the creation of a digital creature, a deformed (er, secret thing) which was based on marquettes made by a well known (er, secret) prosthetics workshop. Although initially, we were only contracted to do clean-up on a prosthetic suit we were asked to do a 3D version after the producers viewed some of our 3D “skin” tests.

These tests involved creating a digital version of the creature, giving him a fully “working” muscle system, and cladding him in a realistic digital skin. While the muscles and the skeleton of the creature had their own challenges, it was the creation of believable skin which proved the biggest challenge. We used a rendering/lighting technique called sub-surface scattering, which reflects light much like human skin (or any translucent thing). We also embedded a circulatory system into the skin (which provided a hint of veins, and changed the creature’s pallor as he became… er… aroused).

Feathering acceptably organic creatures, people, or whatever in amongst the real is an interesting challenge. The big studios have been doing it for a little while, with varying degrees of success, but suddenly the smaller “boutiques” can do it too. I guess the technology to user curve is shortening every day.

The applications are also very interesting.

Taken to a more zoological context, the same system can be used to create believable animal skin, wrinkling, musculature, and skeletons. The advantage of course, in being digital, is that colour, temper, action and speed can all be controlled in a very direct way.

Additionally, using the artificial intelligence (AI) engine in software such as Massive Prime (better known for making crowds of humans hack each other to bits), one is able to randomise/customise the behaviour of a many creatures. In this situation, it will be the subtle addition of chaos which makes it more believable. Using the AI engine from something like Massive will give that edge.

It seems the more chaotic or unpredictable the actions, the more invisible the work becomes…

lens.jpgThere is quite an interesting (old) post on Indie 4k about Birger Engineering’s 35mm stills-lens mount adapter for the RED One. The interesting bit is not the lens mount itself, but that you will be able to control aperture and focus from the camera, as well as getting “metadata” (much like the Cooke /i Technology), so your focus, aperture and lens type are recorded at the same time as the footage. The lens and the body, like, talk!

It is a screw-in/dust free job (similar to the already offered Canon FD and Nikon N adapters), so not a super-neat-o-pop-on-and-off solution. Not that you’d probably want that anyway.

Of course, pulling focus might be a bit of a problem with a stills lens—but that can be solved by using the related Birger follow focus disc. Or if you are cheap or otherwise inclined, with a third party addition such as the RedRock microLensGears which just clamp around the lens.

From reduser.net:

The Canon EOS EF Mount, designed by Birger Engineering, will enable the use of Canon EOS EF lenses on the RED ONE. Focus and iris will be controlled via the RED SuperGrip or by Birger’s own wired or wireless interface. Focus control is in 4,096 steps from CF to infinity. The Lens mount also requires a $75 LEMO cable. The follow focus disc is $300 and the required LEMO cable to connect it is also $75. There will be a wireless controller with an LCD and two control surfaces [a slider for iris and knob for focus] available for $600.

Available (or soon to be available) mounts are:

Canon EF-S (control iris & focus w/ “EFâ€� & “EF-Sâ€� lenses; available 15 December)
Sigma SA (control iris & focus; available 15 January)
FourThirds (control iris and focus; available 15 February)
Nikon F (control iris with “Dâ€� & “Gâ€� lenses, focus with “AF-Sâ€� lenses; available15 March)

Whichever way, it would seem like a pretty cheap way of expanding the lenses at hand, especially if you don’t have a case of Cookes sitting next to you. Considering RED branded lenses are rumoured to be re-stamped (and re-housed) Sigmas, perhaps there is not too much optical consideration required?

However, there is a question of what crop-ratio this lens adapter gives you. Of course, it will be the same as a 35mm motion camera will give you, and not be what a stills camera will give you. This is because the RED sensor (24.4×13.7mm) is much the same as a lot of digital SLRs (for example, Canon’s 40D is 22.2×14.8 mm). Which is also much the same size as a Super 35 frame (funny that). A 35mm stills image is larger (36mmx24).

36mm ÷ 24.4 = 1.475

The disparity between the digital sensor size, and 35mm negative size means you get ~1.475x “sensor crop“. Or in other words, if you have a 50mm Canon EOS lens, it will need to be multiplied by 1.475x to get the equivalent “35mm stills” field of view (in this case, 74mm).

As I mentioned, this won’t make a lot of difference, or be particularly enlightening if you are used to shooting (super) 35mm motion—because the result is the same.

Rather, it is just something to bear in mind if you are going to go the stills lens route. What you see through the lens in the RED or a 35mm motion camera, won’t be the same as what you see through a standard-sized stills camera. So your wacky 10mm lens is going to turn into a rather sensible 15mm (okay, okay, a 14.75mm [10mm x 1.475])…

Maybe it was time to trade in that Hawaiian shirt for something neat and black anyway…

Slim Pickens going down...

Is it just me, or does the news of the US shooting down a giant, degrading, flying fuel grenade, evoke an image of Major “King” Kong riding that A-bomb out of a B52? But now that China and the US are one-for-one, what’s next?
