Why is skin tone such an important deal? Shouldn't we be looking at trees and bricks for aliasing? Eh, not so much.
At the end of the day, your audience – especially with a narrative film – is going to relate with humans. And human faces tend to show emotion which furthers your story. And that's the essence of why we pay our A-list actors so much, right? So shouldn't our cameras help us in capturing this detail?
The skin is translucent and very rich in luminance and color. Film stock has often been touted as rendering this translucence extremely well while digital technology tends to ‘smear' or make people's faces look ‘plasticy' – rather flat in tone, missing subtle flesh richness. In DSLR still photography, huge pains with sensor and color technology, coupled with RAW editing ability have allowed photographers to get back to achieving superb skin tone and detail – which was first missed with early implementations of compressed, low megapixel jpg stills.
Regarding video, it seems we are working where early DSLR still photography began: low resolution (1080P is around two megapixels), highly compressed images with limited color depth (8bit).
So, let's look at a few still images taken from a shootout video Adam Roberts created that will be shown later after the poll ends. A few very popular cameras were used for this shootout. Adam explains the set up was a single 1K tungsten fresnel bounced off a polly board (camera left) with a silver fill reflector (camera right). All Cameras were set to ISO 800, 3200k, 25P, color matched in FCPX. I'll be the first to say this is not completely scientific and the color grade may not be to your taste (or mine). But I do think this is a good test.
So which do you prefer? A, B, C or D and why? Remember, look at color, detail and subtle skin translucent rendering.
After the poll, I will discuss the power of color grading and the difference of still photography and motion photography in regards to how we perceive skin tone detail. Please view full screen and diligently study the images, that would be beneficial.
