I shoot a lot of film, but there are occasions where you can't beat the convenience of digital photography. Airshows definitely fall in this category. Aircraft move fast and no two frames look alike no matter how fast the camera can take them.
This year I got the chance to go to Wings Over Houston. One of my favourite shots of the day was this one of the Lucas Oil Pitts S-1-11b, flown by Michael Wiskus. I don't know if it was intentional, but it was quite a cloudy day and Michael found a wide gap between the clouds to execute this falling spin. Smoke trails are more defined against the blue sky than the clouds.
It is tricky in photography to portray time within a static image, but the smoke trails map the movement of the aircraft as it plummets.
Wondering if I should shoot medium format film next year, I tried a black and white conversion using Nik Silver Efex and their HP5 emulation. I added a red filter to increase the contrast between the smoke and the sky. The only drawback is loosing the red colour of the plane.
