Increase or Decrease Intensity
Here’s a quick and easy lesson to make your life a little bit easier.
Sometimes when you bring a light up, you look at it and say, “That’s a little too bright.” or “That’s a little too dim.” You could type in a entire new command, but EOS allows you to simply “bump” the brightness up or down using the [+%] and [-%] keys, or Ctrl+Alt+(-/=) on your computer keyboard.
Let’s try it out.
Whatever cue you’re currently in, doesn’t really matter – let’s use Channel 1. So go ahead and type  [@]  [Enter], which will set channel 1 to 55%.
If we wanted that channel to be brighter, we could type [@]  [Enter], which would assume we want to keep using Channel 1. Or we could bump the [+%] button and EOS would push the channel up by 10% (this amount can be changed in the EOS settings).
Keep taping the [+%] button, and eventually we’ll hit our limit of Full or 100%.
Let’s now go the other way and press the [-%] button. You’ll notice that we didn’t go back down to 95%, but went to 90%; That’s because the last time we pressed the [+%] button the value went up by as much as it could, 5%. The thresholds of 0% and 100% will simply round our values. Try finding our bottom threshold by tapping the [-%] several times until you hit 0%.
These buttons will also handle relative percentages. So in the cue above, if I were to capture channels 2 and 5 by pressing  [+]  [Enter], I could press [-%] [-%] [-%] which would drop by channels down by 30%.
That’s pretty slick, isn’t it.
A quick note. If I were to continue bringing these channels up or down, eventually they would all hit their thresholds of 0% or 100% and then they would be the same values. But that’s okay. Just Sneak them and start over.
