Triple Bandpass filter: The good news and the bad news

Filming is definitely easier with the Triple Bandpass filter TB550/660/850 (link) than with the orange-green filter method discussed in previous posts (link). The blue vegetation, which turns reddish after the channel swap, is already present here, which greatly facilitates processing.

When it’s just about taking pictures, it’s a different story. Here I clearly prefer the orange-green combo, mainly because the contrasts are much stronger and the look is just (for me) more like the Aerochrome style I admire. I suspect that has mostly (but not only) to do with the weaker IR contamination.

It’s so simple to get dark red vegetation: In contrast to the Triple Bandpass filter, it is so easy to get the blue tones (which turn red after the channel switching) really dark and strong. At the same time, the color variance (for trees, grasses, firs, etc.) is just as good as with the Triple Bandpass filter.

And hey – if we go by the price of new – the orange-green method is much cheaper. You just need a Hoya X1 and a dark yellow or orange filter (between 15 and 21). Look on Ebay. The X1 is available by the dozen and relatively inexpensive, the orange filter is a bit more expensive and rarer.

But I’m glad I tested the TB550/660/850. Here are some cinematic impressions:
