Haha thank you, I've been using lightroom for awhile, but there are still sliders in the detail section which I do not fully understand the impact of using them. For instance when using the sharpening, I rarely use the detail or masking as I do not know what it really does. Same thing with the color section of the noise reduction, no clue. Thank you both for the compliment though!
It depends on what mode your in. If in Av or Tv, you can just use the dial to tell it to over or underexpose (see the Exposure comp meter). I believe I was 1/3 or possible 2/3 over. If you are shooting in full manual and the lighting conditions are typically stable, you can just dial in your aperture, shutter, and raise the iso (or really lower the shutter speed, or even open your aperture, just depends which you prefer, I did ISO as I wanted f/2.8 and a fast shutter) until your meter shows you are over exposing for however much you'd like. Hopefully that helps, I'm more hands on so I may not have explained it the best.
When sharpening the mask slider is a good one. After adding the amount of sharpness you want, hold the Alt key down (on a Pc, I think it is the Opt key on a Mac), and then move the slider to the right. Keep moving it until just the edges you want to sharpen are showing. That way you don't sharpen the background or other such areas which would bring back some noise in those areas.
I shoot a lot in manual mode with auto-ISO. If you want to overexpose slightly you can just bump up exposure compensation (which you can do in the 7DII) 1/3 of a stop or more. You can go into custom settings and set it up where you can push and hold the set button and the turn the upper wheel by the shutter button to set exposure compensation on the fly.
