Hoya 72mm グリーン X1 写真用レンズフィルター

Green filters usually make skin look weird, but this one under tungsten actually keeps fleshtones natural without that washed-out effect. My indoor group shots finally look like real people instead of green aliens.

Finally, indoor shots of my kids don't look like they've been dipped in orange juice—the tungsten correction is spot-on, and their skin tones actually look like skin. It's a solid green filter that does exactly what it says, and I've kept it on my 72mm prime for every evening shoot since.

It took some fiddling to get the white balance right, but once I did, the flesh tones in my indoor portraits under tungsten light look so much more natural. The green tint is subtle but it really does the job.
