Shot in the dark

Quick preliminary test of the new camera body’s low-light capability (double-sized if you open it in another tab):

This is the view of the neighbor’s house from my back yard, with no streetlights or other lighting, at midnight with no moon. It’s soft and quite noisy, but it’s clear and in-focus.

It’s also about three stops overexposed, because this is what the scene looked like to the naked eye:

In other words, it was able to successfully meter and auto-focus (admittedly with help from the built-in focus lamp) in conditions where I couldn’t even see that there were fences. Exposure was 1/30 at f/1.2, hand-held at ISO 204,800. By comparison, the latest and greatest iPhone tops out at ISO 12,768 with an f/1.78 lens, which would give a ~1.2-second exposure, if it could meter the scene at all.

Here’s a crop showing what the noise looks like on the full-sized image. Rough, but there’s still some good detail, and it can be cleaned up and sharpened.

No temple, castle, or museum is even close to this dark inside, and I haven’t even tried the built-in HDR features or adjustable Dynamic-Range Optimization yet, so I don’t think I’ll have any trouble getting clear, crisp pictures of anything I can see. The zoom I’m taking has a constant f/4 aperture, so there may be conditions where it has to use a noisier ISO setting, but I don’t think I’ll need to crank it up to even 100K, much less this setting.

And, of course, I’ll be carrying my small LitraPro color-corrected USB-powered LED light. Which is sadly discontinued now that Logitech owns Litra and just used their IP to build a clip-on light for streamers. It looks like the Luxli Fiddle is the current hotness for pocketable LED lighting, although it’s only half as bright as the LitraPro.

Metering digression: the Sony A7S III’s meter sensitivity is EV -3 with an f/2.0 lens; with the 50mm f/1.2 that’s still only EV -4.5, and this exposure computes to EV -5.5, so it got a little help from the focus lamp, even though it was half-blocked by the lens hood.

Juxtaposition, Twitter style

66% No Yuuwaku revisited

So, quite some time ago I posted the cover art for the Japanese release of Meatloaf’s Two out of three ain’t bad single, which translated the title as “Two-thirds of Temptation”. Randomly, I found two things recently: a fan translation of the English lyrics, and the actual lyrics that were included with the single:



僕の目からは涙でなく、 つららが下がった

“君が欲しいんだ、君が必要なんだ” とね

TL/DR: it’s just the first verse, simplified but pretty much on target until you reach the last two lines, which are as far off as the title but in a completely different direction: (roughly) “out of three people, it’s not a bad thing when two of them leave”.

Props to the big G for Google Lens; when I fed it this JPG in the hopes of finding a higher-resolution source (because no one had ever transcribed these lyrics), it couldn’t find one but still managed to OCR almost all of the kanji correctly. The few errors were easily caught and corrected.
