21st Century Technology . . . or just pure sweet timing?

I recently photographed the Australian Masters Indoor Cricket Championships.

Unlike the outdoor version, INDOOR Cricket is a blur of almost non-stop action: a little yellow ball zipping around a net-enclosed court at over 100 kpm, and 10 players running, diving, jumping and otherwise moving all the time.

The peak action moments are the split-second when a batsman and the ball meet,



and the split-second a batsman sprints across the "crease" (the marking on the ground beyond which, once crossed, the batsman is "safe") as that moment coincides with the ball hitting the wickets.


This post is about the latter, and the "human timing over technology" aspect therein.

In the first instance (batsman and ball meeting), the drama of the photo is maximised if the exact moment the ball hits the stumps is caught.

In the second instance, that drama is maximised the closer the batsman's bat is to the line.

Over the course of this tournament I published each day's photographs on the same evening they were taken. And each morning I'd hear comments along the lines of how good my camera's motor-drive or continuous-shot capabilities must be.

Bah humbug!!!

If I'd relied on the technology of my cameras, I'd have missed dozens of perfectly-timed shots like those above, even though the Nikon D4 I was using is capable of taking 11 shots per second . . . but mine doesn't because I shoot single shots. I never use continuous-shot mode (aka motor-drive for older, not-yet-caught-up-with-digital folk).

I've had more than one punter scoff at this assertion, until I explain the following:

at full stretch, a fit batsman in indoor cricket might be running at about 7 meters per second. The D4 can take a photo every one-tenth of a second, so between one frame and the next our batsman could have covered 70cm. So he could be up to 35cm before or beyond the line . . . 35cms!!

And what about the ball? While many can bowl at over 100 kph, let's say it's travelling at a leisurely 60 kph. That's 1 kilometer per minute. That's over 16 meters per second! Again, a photo every one-tenth of a second . . . between one frame and the next, the ball has travelled over 1.6 meters!!! So we could end up with a photo of the ball nearly one meter away from the stumps, or nearly one meter past the stumps.

Compare that to the photos above . . . on continuous shot mode, I would have been relying on luck to get anywhere near that position of the outstretched bat, or the ball just centimeters away after crashing through the stumps. In such situations, my sense of timing is going to trump the frame-per-second capabilities of even Nikon's flagship camera. Always. Each and every time.

Now of course there are situations where the high frame-per-second capabilities of modern cameras are going to be very handy . . . I guess . . . many sports don't have the same well-defined critical moments as discussed above, so blazing away at 11 shots per second, without having to worry about little things like timing and anticipation and understanding the game and reading the flow of the game etc etc, is going to get some interesting and exciting shots.

But for real excitement and drama, to really capture the essence of the sport and to capture that . . . ummm .  . . what's it called? . . . ah yes, to capture that "decisive moment" (now where have I heard that before?) . . . for me, nothing beats good old-fashioned human timing.

Time-lapse with a DSLR (or why I miss 35mm film less each day)


You know, I'm missing 35mm film less and less nowadays . . . yes, I know film has "the look". I know it has the feel and the history and the smell and the romance . . . and the cost. And the waiting. But in many ways what is more important now is what it doesn't have.

In this post, the "what-it-doesn't-have" I'm most interested in is the capacity of modern DSLR cameras (in my case both a Nikon D200 and D700) to shoot time-lapse video. No video camera required, all it takes is one of my Nikons, time, and the right software. In other words, NO specialist equipment, just a tripod and the Nikon. This is something I wouldn't have dreamed of trying with my film gear, but with digital, it's a breeze.

Software requirements can be covered in a few ways, I'm trying LRTimeLapse (free for non-commercial use) and LightRoom 4 (definitely not free, but hey . . .). LRTimeLapse allows for some very professional looking effects, including the slow "Ken Burns" effect (very slow zoom in then out again), and LR4 allows full editing of levels, sharpness etc and use of a vast array of digital filters.

The results?

See for yourself. Here's my very first attempt using this software combination. Please note, this is a very low-res, bandwidth-friendly version, the original is astonishing, in full 1920 x 1080 HD, rendered at 30 frames per second:


For Nikon DSLR owners, the necessary interval shooting is via the built-in intervalometer in the D700 (and most other newer models I think--even my old D200 has this feature). Just set it and go away for an hour or so, the camera does it all for you automatically. This particular effort involved 600 photos (one every 5 seconds), but I only processed 400. I sat around for 50 minutes enjoying the view while the camera tripped along. Half an hour editing and rendering and there it was!

Here's a more recent effort, again using this software combination, and again a very low-res, bandwidth-friendly version. The original of this is amazing, the sun's rays rotating across the sky while the higher clouds move in the opposite direction. Again, it is full 1920 x 1080 HD, rendered at 30 frames per second:



Like I said, I'm missing 35mm film less and less these days.
