LUTs

Do any of you use LUTs? I keep seeing this term, and I had to look it up - appropriately, it means "Look Up Tables."
What's the story with them? Am I missing out on something?

Personally? No.
But Domain Name Servers (DNS servers) have lookup tables to see where to send your URL request.
I used look up tables in dBase years ago, but we called them "lookup tables".
No one I know used the term "LUT".

No but my monitor calibration software does. It creates the LUT to load into the monitor.

If there was an "e" on the end, I would understand. "Lute"

LUTs are supported in Lightroom Classic. Similar to presets. I don't normally use them.

Way back when, we have used look-up tables. Only they were more specifically named: multiplication tables, trigonometry tables, log tables. Rather than calculating the square root of 2 (which can be done), we'd look it up and find it was 1.414. Likewise in software, LUTs are used to speed up calculations.

LUTs are popular with videographers. It is to video what a preset is to still pictures/photography. With my Nikon Z8, I can use N-log (N = Nikon) as part of the set up I film video. In fact, Nikon actually has a N-Log LUT that we Z8 people can use. It's available for download on the Nikon website.

Never heard “LUT” but remember lookup tables in software for aircraft navigation… and… lookup tables in spreadsheets and being used by formulas.
I also remember acronyms and abbreviations varying with every military organization I was in (1 to 3 years in each organization from 1964 to 2012). Every time I moved organization and base… it was like they were speaking a different language.

LUTs are used in color grading of pictures and videos. Below are two links describing how you can use them. You can think of them as being similar to presets. You can find free LUTs online to use with your favorite editing software usually. The files associated with LUTs are "cube" files and most editing software recognizes them.

You can buy LUTs as well and below is an example for Luminar Neo, just one of the pieces of S/W I use. This is best viewed with chrome browser:

Thanks. I don't shoot enough video with my Nikons to get into LUTs.

I believe they’re also used in Microsoft Excel.
Nice new avatar. Very handsome!

I use them. I have a Panasonic GH5 with V-log. The use of a LUT allows me greater color balance control when I shoot video.

All kinds of different uses in computing for look up tables. Essentially, it’s an array of values/numbers that maps a given input to a specific output. You input a number/value and the LUT outputs a different value associated with that specific input. Graphics cards (and some monitors) use an LUT, so when you calibrate a monitor. the corrections are made to the LUT. Then when a value for a specific pixel is input to the LUT, the output with the corrected color/saturation/brightness of the pixel is displayed on the screen.

Yup, use them all the time...much like "split toning" and can really add a "finishing touch" to an image, in my opinion.
