I've been a bit slack keeping up with my published cover shots lately. Which is how I find myself with three consecutive What Mountain Bike covers to share:
Nikon D3, 80-200mm f/2.8, 1/250sec f/6.3 @ ISO200, two radio slaves
Nikon D3, 80-200mm f/2.8, 1/80sec f/6.3 @ ISO800, two radio slaves
Nikon D3, 24-70mm f/2.8, 1/200sec f/7.1 @ ISO640, two radio slaves
There's something these three covers have in common: none of them are shot wide. The shortest focal length in use was 70mm, and the longest 130mm. Why does this matter? Because, as students of any of my courses will know, long lenses take the viewer away from the action and slow things down. Looked at another way, shooting a mountain bike in close with a wide lens is a good way to involve the viewer in the action, adding a dose of drama and movement even in situations where there's not much of either happening. Step back, put a longer lens on, and the viewer involvement decreases.
In other words, the further you are from the action, the more you're relying on visual cues to impart the sense of movement. It's very easy to take a boring shot of mountain biking on a long lens, particularly from head on. There needs to be something going on to grab - and hold - the viewer's attention. Usually, in the absence of obvious movement, it's all about implied movement.
So in the first shot, we've got a climbing rider working the bike hard, out of the saddle and about to put in a power stroke. Timing is critical in an image like this - bike upright and pedals level just won't cut it. The fact that the rider's smiling doesn't imply hard effort (although it works in this context, because publishers like readers to feel that riding a bike is fun), but his body position does. You won't be able to see it here, but there's also enough movement in the front tyre's tread to show that the bike's moving.
The second shot also makes use of the rider's body position and facial expression, but it's helped along by a slow shutter speed and the added interest of plenty of backlit spray. The bike's hauling - and you know it. I actually tried some wide shots of this corner and they didn't work as well...
The final shot is all about the rider's position on the bike - elbows bent, body low and pushing the bike into the corner. The shutter speed's higher than I'd like on this one, but what you can't see is that as soon as i'd taken the shot the rider needed to straighten the bike and push it the other way into a berm. My attempts at slowing things down just resulted in too many shots with blurred handblebars or face. The first isn't ideal; the second is a definite no-on. Details matter, and it's my job to get them right.
Nikon D800: lots more, for the same. But how much is enough?
Unless you've been asleep under a bush for the past couple of days, you've probably noticed that Nikon's completed its pro dSLR one-two with the announcement of its D800. It's the 5DII-killer that Nikon shooters have been clamouring for for the past couple of years. In fact, given its specs and price, Nikon clearly expects it to be a 5DIII-killer too. Canon will have their work cut out to match expectations, now that Nikon has shown their hand.
In case you haven't seen the specs, the salient points are thusly:
- D700-ish body with some styling tweaks and a small drop in weight (yay!)
- 36mp at 4fps, with a 15mp DX crop mode that actually looks like being genuinely useful
- all the weather sealing and robustness you'd expect (though not quite as much as a D3/D4)
- nearly all the D4's video cleverness
- price back to D700 price at launch
In other words, it's one heck of a lot of camera for a price that, although not a trivial sum of money, actually gets you an awful lot of very solid performance. What particularly interests me is the DX crop mode, which offers more pixels than my D300 and is therefore genuinely, supremely useful. The AF sensors cover almost all the DX frame. See where i'm heading with this?
However. 36 is a very big number indeed when we're talking millions of pixels. You don't get something for nothing, so anyone expecting a D4 sensor in a small body is going to be disappointed. Specifically, the D800 loses out on high ISO (though it's likely to be at least as good as the D7000 in this respect - which is to say, very good indeed, though not quite up to D3 levels). It's also not particularly fast, although 4fps is perfectly useable. Anyone wanting more than that out of a high pixel count camera needs their head examining... 9fps @ 36mp is getting on for 1Gb per second.
There are also the tangentially related issues of lens performance and diffraction, as well as the weakest link of all in the image quality chain - technique. I'll make a prediction now: an awful lot of D800 buyers are going to be disappointed with their results unless a. they own absolutely stellar lenses and b. have the technique to get the best out of them. The intersection of those two groups is a fairly small number...
From my point of view, as intrigued as I am by the D800 it doesn't actually solve any of my needs. There's no way I - or the vast majority of my clients, the vast majority of the time - need anything like that many pixels. If I were habitually making A2 or bigger prints, on the other hand, i'd be lining up to buy one straight away. It's certainly a lot of camera for the money.
