It's called a rolling shutter artifact.

comment Why do I meter under the chin with a lightmeter?
you want to meter the darkest parts of the image to ensure you have sufficient signal in the shadows to resolve the image well this still implies the lightmeter is measuring the darkness of the shadows which is the exactly the misconception that prompted the question in the first place, and is out of line with common practice. If you wanted to ensure the shadows were within a certain range you'd just point the lightmeter dome toward the fill light/reflector. Since all of the subject skin will reflect the same amount of light you only ever need to record the incident levels.

The correct way to fix problems such as shadow noise in portraiture is through extra lights / reflectors, not by ETTR (which is more for landscapes, where you can't fill light a whole mountainside). The best way to meter for portraits is to measure the incident light, not the light reflected from the subject. If only one reading was taken it was almost certainly an incident reading. I've never heard of anyone taking a single reflected reading from a shadow area in order to completely determine the exposure for a portrait!

comment How can I get perfect sharpness when shooting still art?
@user28116 Firstly "don't overexpose" is shorthand for don't push the exposure so far you run into problems of clipping and nonlinearity (in any case avoiding nonlinearity in no way requires underexposure by 2 stops!). If you start with the camera's 18% metering reading and go down two stops from there you really are going to lose quality. Finally I will "ride" that answer until the laws of physics and mathematics change to render it incorrect :)

@user28116 Digital sensors are very linear with respect to incoming light vs. recorded value (unlike film) so provided you don't overexpose you'll capture the full range of details no matter where you place the exposure. Reducing the exposure, on the other hand, will absolutely increase noise in all circumstances.

Likewise, why less than 1 second exposure and ISO200, can you provide any more details?

I'm not sure what underexposing is going to do to help detail (if anything it's going to increase noise) unless you're getting problems with mirror slap at certain shutter speeds.
