#JPEG #JFIF

🎨📸 Look, #Apple has reinvented the wheel again! Now you too can decipher the arcane magic of #HDR with a string of random numbers and letters. Who knew image quality relied on summoning the ancient text of #JFIF and AMPF? 🙄📜

Just sent a photo to my family group #MMS with a photo of my grandma and the following caption:

"Title: "Stylish Lady in the Red Hat"
Year: 2023
Medium: RGB value array converted to YUV colorspace and quantized via DCT to JFIF format"

I WONDER if they'll figure out that I'm a #nerd... 😜

'Zum Tod von GIF-Erfinder Stephen Wilhite: "Wählerische Entwickler sagen JIF"'
https://www.heise.de/news/Zum-Tod-von-GIF-Erfinder-Stephen-Wilhite-Waehlerische-Entwickler-sagen-JIF-6625425.html

Ich würde eher sagen: Informierte Leute sagen #GIF um Verwechselungen mit #JFIF aus dem #JPEG-Format zu vermeiden.

#Jpegoptim is a #JPEG optimizer.

Jpegoptim analyzes the structure of input JPEG (and #JFIF) files and optimizes their Huffman trees to decrease the overall file size losslessly. Jpegoptim can also recompress files in a lossy manner to decrease size much more than the lossless method can.
