ついでに、キャリブレーションはだいじ、ってお話をしておくね。
まず、どのディスプレイにも個性があって、同じ色に表示されることはないのね。全部違う。
あと、経時変化があって、一年前に表示されていた色と今とでは違ってしまうのね。
だから、一定の状態を維持できるように、外部から光を測定して、調整する必要があるんだよ。
いつでも同じ状態を保つこと。
プロなら必須。アマチュアでも、品質にこだわったり、印刷したときに安定させたいなら、やった方がいいよ。
そして、PCのグラフィックボードから送った映像の信号が、実際に画面に表示されたときに、どんな色に表示されているか、測色機という機械を使って、サンプルをたくさん測定してデータ化して、ICCカラープロファイルっていうファイルを作成する。
カラーマネジメントに対応したソフトは、sRGBっていう規格、あるいはAdobeRGBっていう規格では、特定のRGB値はこういう色に再現すればいいかわかっているので、そのディスプレイのICCカラープロファイルを使って、モニターにど…

Finally an RGB image of comet #3IATLAS from images taken by #GeminiNorth during the 26 November #shadowTheScientists session: noirlab.edu/public/news/noirla - the coma has become bluer due to more gas emission. Also published today: an X-ray image by XMM-Newton at esa.int/ESA_Multimedia/Images/ with explanations in cbat.eps.harvard.edu/iau/cbet/ which also contains more 3I news.
Meanwhile the paper iopscience.iop.org/article/10. claims an upper limit for 3I's nucleus diameter of only some 750 meters from the measured non-gravitational acceleration (NGA) parameters: that would be waaay more stringent than the 5.6 km upper limit from early Hubble observations reported in iopscience.iop.org/article/10. (where also a lower limit of 440 meters is stated).

Morgen bin ich zum Weihnachtsliedersingen im Stadion in #Paderborn. Ich wollte mir dafür einen Anhänger basteln, der passend zum Gesang leuchtet. Leider habe ich zu spät bemerkt, dass ich kein passendes Mikro da habe. Für die Demo wird es über LedFX auf einem Laptop gesteuert. Morgen dann leider ohne reaktiven Effekten.

Zwei Hände halten ein durchsichtiges, runden Plastikteil. Drinnen leuchten ringförmig LEDs auf. Immer wenn gesprochen wird. Bei tiefen Tönen gelblich, bei hohen blau und grün. Je lauter, desto mehr LEDs leuchten von unten links und rechts nach oben.
