Tiff is for science. Like for actual values that need more than 0-255 level of precision.

For example we use Tiff (or GeoTiff because it has coordinates) for storing elevation, temperature, slope, etc variables of an area for processing. It can also have a lot of bands not just RGB.

For example, satellites record RGB, infrared 1, infrared 2, and many other bands and even if we can’t see them it’s useful to get that information for processing. That helps for example to recognize river from forest even if both look green to our eyes.

Repeat after me:

JPEG is for photos, PNG is for graphics.

I learned English reading so many books that I just pronounced how it’s spelled in my head. Combine that with general non-social tendencies I didn’t really heard or had to say a lot of those words.

I had to spell out words to people because of that. Then I came to US, and now I can’t even spell the words because the alphabets are pronounced differently lol.
