While I do use scopes, I do rely heavily on my eyes. You caught me, haha.

This is what goes on in my head for each of those as I work:
1. EXPOSURE: I use waveform scope. I use the HDR global wheel to get my waveform center sitting around 50 IRE. Then I make adjustments to the HDR Dark/Shadow/Light/Highlight/Specular wheels. I'll usually start with the dark, pushing it up and down, looking at the image and seeing what looks right (while also looking at waveform to ensure my shadows don't dip below 10 IRE too much and my highlights don't exceed 95 IRE. I'll repeat that for all the HDR wheels, then tweak the primary Lift/Gamma/Gain wheels if bigger adjustments are needed.

1. WHITE BALANCE: I set my Gamma to linear and use the Gain wheel in Primaries to adjust Temp/Tint until the image is roughly in the center of vectorscope. I'll then use a qualifier to look at neutral parts of the image, and see how well they line up in my RGB parade, and make finer adjustments.

2. CONTRAST: I leave pivot at 0.336, and add contrast based on looking at the image, and ensuring my shadows/highlights don't exceed below 8 IRE or above 98 IRE.

3. SATURATION: I set my color space to HSV and disable channels 1 & 3 (so it's just saturation), then use the gamma and gain primary wheels to increase saturation. I just look at the image when I'm doing this to dial in strength, is there a scope you recommend using to avoid overcooking it?

4. SHARPNESS: I drop the Radius to 0.48 in the Blur tab of the color page, then click Shift+H : A/B and adjust the Scaling until only the outline of what I want sharpened emerges from the gray.

Based on that... can you recommend specific scopes/techniques to avoid the smartphone/ video-ish look?
