Da Vinci Resolve:

Color Grade on Product Shot

Simple Method for Clean White Color Grades
Balance the shot color first, then there is 2 methods:
1.Create new Node, tune down Col Boost at Wheel till the white color in shot looks neutral, then bring up saturation which is lost on non white color part due to Col Boost changed (Result will keep background color neutral, while subject color gets back its color)
2. At new Node, go to Sat vs Sat Curve, add a dot on 2nd left square, then drop the 1st dot to zero:

Then slide the 2nd dot towards right gradually, until the background looks neutral
(The logic behind 2 methods:
Method 1: Because Saturation is multiple value (so 0 times anything also just become 0; while Col Boost is adding value, so 0 can still add 10 will become 10. So once neutral background drop to 0, raise back saturation won’t affect it.
Method 2: Take color of low saturation (i.e. near grey color) and pull them to 0, so anything on image close to grey is fully grey) 2:50 to 4:50
Method 1 is better than 2, as method 1 creates more color separation, more natural, and more user friendly to adjust by knob, if panel is available.


Clean White Look in DaVinci Resolve 17
Create 6 serials nodes: Exposure, Balance, Look (2 extras Red, Blue Nodes in parallel), Look Adjustment, Vignette, Midtone
Makes the white background white (neutral color tone):
After adjust exposure node and color balance node, create a Look node (4:00)
Reduce Gain in Wheel to ~0.80 (under exposure), then go to Bars, push up Luma to ~1.00 (grey bar) in Gain, then reduce Color Boost (left bottom column) a bit (-8.50)
To separate other colors from the white background:
-At Red Node, Go to Color (top menu)→ Preset → Six Vector-Red. When click the Highlight icon (next to split screen icon), will qualify the red tone part only
Go to Gamma and Gain in Wheel, adjust towards yellowish red (depends on what color need to separate, here is red) to make the color looks natural
-At Blue Node, repeat the same step (Red and Blue depends on the subjects color, for my test product, they are mainly red and yellow)
At Vignette Node, create window , tone up Gamma and contrast
At Midtone Node (for soft and creamy image), reduce MD (midtone detail) to -20 (Increase MD will sharpen the image instead)
At Look Adjustment Node, go to Color Warper, darg the dots to specifically change colors tones (use HSP graph as reference here)

Details in Color Warper:
At Hue-Saturation icon, on the Grid, Go from centre to edges is for saturation, Go round along edges is for Hue. Can work on the Shot by dropper, don’t need to work on the Grid/graph, can be seen the cursor on Grid changed when the dropper on different part in the Shot)
At Chroma-Luma icon, go from left to right controls color shift from blue to yellow; go down-up controls brightness


How to get Netflix's DARK look
Fx Color Palette function helps to check color of the shot
-Create 5 Nodes: Noise Reduction (NR), Balance, Saturation (extra parallel node called Look), Node Adjustment
-Right click the small box behind parallel Nodes→ Morph into Layer Mixed Node→ Right click, Composite Mode→ Overlay (create a bleach bypass effect (i.e. characterized by high contrast, low saturation and sometimes an overall coolness to the image, feels raw, intense and gritty / silverfish look in Highlight Part )
-At Balance Node: Highly boost Highlight (~1.45), boost some Contrast
-At Saturation Node, boost Sat level (to max 100?)
-At Look Node, go to Bars , turn Lum Mix down to 0 (to individually affect each channel), adjust each R,G,B bar in Lift and Gain for what we want
-At Look Adj Node, go to Curve Hue vs Hue, adjust what it needs
-Add 2 parallel Nodes behind Look Adj Node (to separate highlight and Shadow), each of them selected by Qualifier→ Luminance→ L.Soft about 2.2 and then drag the Low to about 50 on Highlight Node;
while H.Soft about 2.2, and High about 50 on Shadow Node (11:25-11:48)
At 1st parallel/Highlight Node, go to Wheel and reduce Hi/Light (can be down to -100, if the highlight part is too hot/bright), then shift the color wheel at Gain towards yellowish skin color a bit, if we need to add/take out some colors
At 2nd/Shadow Node, pull down the Shadow Wheel in Log a bit
-At NR Node, apply noise reduction (the youtube clip case just change Chorma to 6.8 at Spatial Thershold. Temporal tune mainly enough for static shot, Spatial part may tune as well if it’s a moving shot)
-Add a fx film grain Node at last
-Add a Global Adj Node before Film Grain, adjust Lum vs Sat/Sat vs Sat/Sat vs Lum to pull the curve up/down (B&W curves at last 3 dots, not color Curve)
To achieve pure blackness background: At Log, highly reduce Low Range (down arrow+Rng sign)→ reduce Shadow a bit
