"Scenes from an Airshow" is another real-world example of Mosaic Engineering's VAF-5D2 anti-aliasing filter in use. This year's event took place on Sunday, September 11th, the 10th anniversary of the infamous attack on America.
(I'll never forget 9/11/01. We were shooting a commercial in Jay Verno's Pittsburgh studios the day the Twin Towers fell. We didn't know if we should continue shooting or just go home…)
In this video, I used the popular Technicolor profile for the Canon 5D Mk2. This free, downloadable profile logarithmically flattens the 5D's contrast, allowing scenes to be photographed with much higher dynamic range. Without this profile, much of the sky would have been clipped white, with little or no detail in the clouds.
I slightly modified the recommended Technicolor settings by adding an additional 1 click of in-camera sharpening. In retrospect, I would not recommend doing this. The 5D Mk2 seems to "enhance" the image, rather than actually increasing sharpness. In the aerial shots, you can see a slight outline around the darker aircraft. It would have been better to apply a slight bit if sharpening in post if you need sharper video.
I used Final Cut Pro 7's simple "3-way color corrector" to restore the low contrast video's dynamic range. (No other timeline filters were used.)
All scenes were shot with a Canon 70-200mm F2.8L IS or a 24-70mm F2.8L zoom lens. The 24-70 was usually set between 24mm and about 35mm. The 70-200 was usually zoomed all the way in at 200mm. Both lenses had Tiffen 77mm circular polarizer filters to enable a 50th of a second exposure at ISO 160 in daylight.
The striking, hard edged shape of aircraft with their logos and other designs is a pretty good example of scenes that would naturally be prone to aliasing artifacts. The VAF-5D2 filter does a good job of masking the problems caused by line skipping.
