I shot film primarily for photojournalism in the late ‘80s thru the ‘90s. Film pushed to ASA 25600 would be a veritable sandstorm.

カメラでまともにホタル撮ったのは初めてで、1/10s F1.4 ISO25600でも発光部以外なに写ってるかマトモにわからん(飛んでるときならもっと光る？)。時間帯とか場所とか設定とか色々やりようがあるんだろうな。

未知の被写体に遭遇するのは楽しい。

Nightly encounter. Next time I will get the focus right. Images taken around midnight at 1/250s f5.6 ISO25600 on 400mm lens on R7. Heavy denoising and exposure correction in post.

K-70だけど実際ISO12800くらいまでは許容範囲みたいな感じだから感覚的にはわかる記事だった
だいたい上限マイナス2段くらいまでは緊急で使える肌感がある（K-70だとISO25600）

This morning it was overcast and drizzling in Central Park, so I (stupidly) decided to try taking photos of rough-winged swallows in flight. I ended up with 900 shots, all of them at ISO25600 and 75% looking like this: #birds 🪶
Blurry dark photo of trees reflected on water. There's a rough-winged swallow at the bottom left corner but the head and part of the wings is out of frame.

ＧＷ（ゴールデンウイーク）前半は曇天つづきでスッキリした星空は望めそうにない予報になっていますから機材手入れ画像整理で過ごしたいと思います。 さて、本日は題記画像の紹介です。

log₂512=9なので500枚くらい合成したらISO9段分のSN比改善なんだよな...
仮に撮影時ISO25600だとしても500枚連写でISO50相当までノイズを除去できるってこと...?

100-400で行くけど、70-200持ってった方がいいのかな・・・
初めて行くコースでナイトステージだからな～
日没後スタートだけど月齢17.6だし行けるか！？
ISO25600までを許容する必要もあるかもなあ・・・

流石にダウンでいこｗ

ISO25600、テクノロジーはすごいですよ☺️🐦️フィルム時代は1600ないし3200とかがMAXでしたよね？
