ScopeBox is a tool I’ve really enjoyed using.
White BalanceWhat do you think this color represents? What real-world object?
“A good log image is just as re-white-balanceable as a raw one.”
Caucasian skin tone, in an intentionally evenly-exposed image, generally sits around code value 600 on Resolve’s confusing scopes.
Add saturation selectively to cyan/blue.
Alexa ‘look’, a lot of it has to do with the Alev sensor’s red channel response
A final fast and dirty trick to give footage the ‘Alexa look’ is a simple one node operation. Change the node colorspace to YUV and in the curves select the green channel only, then click on the curve around the 0.2 and gently push it upwards.
The YUV trick isn’t as daft as it sounds. If you test it on a colour chart (while viewing a vectorscope) you’ll see there’s very specific behaviour when the individual chroma channels are adjusted. It isn’t the same response as LAB. Using curves to boost gamma on the green channel results in an increase in saturation at both ends of the yellow/blue axis, as well as some hue convergence. Very interesting to observe. Pulling the curve in the opposite direction creates an effect somewhat akin to the Two Strip Technicolor process (in appearance). Straight off the bat you can offer the client a choice of two options: Fear the Walking Dead, or The Aviator
Alexa mimics Film by hitting peak saturation at around 35 IRE and holding until around 65 IRE, before falling off, whereas other digital cameras such as Sony and Canon don’t hit peak saturation until 65 or 70 IRE.
Canon push red toward yellow so that red becomes an orange “fire engine” red, and blue is pulled toward green such that bright greens, like grass, become cooler in hue.
The C300 really wanted to make flesh tones more red than the Alexa did, and portions of our hands that are normally redder than normal skin tone (like knuckles) blended beautifully into the surrounding skin on the Alexa but popped bright red on the C300
