Huh? I thought a 3/4 correction dropped a 5600K down to 3600K.

The full CTO I got drops it down to 3200K hence the name "FULL" as in full correction.

Keep in mind, my IDX X-3 was really blue, so I needed heavy correction to make it look decent, this may not be the case with all LED lamps.

Sorry, I've just checked. 3/4 CTO takes you down to 3200k from 5600k
Full CTO is an over correction with a 5600K light (correct with 6500K). Having said that, filters don't always do what they say in the specs, Full CTB doesn't aways give a correct daylight, sometimes it's a bit warmer.

I mostly just use the 1/8, 1/4 & 1/2 CTO, so just shows you need to check your numbers at times.

BTW It's pretty common to fool the white balance on video cameras to give a slightly warmer look.
