alvestrand has just created a new issue for 
https://github.com/w3c/mediacapture-image:

== "Implementation dependent" settings can't be made interoperable ==
At the moment, brightness, contrast, saturation and sharpness are 
specified as "implementation dependent". As such, it is impossible to 
achieve an interoperable implementation based on the spec.

At least a zero-point, sign and magnitude of the measure should be 
defined - such as "zero sharpness refers to the camera's default 
setting; positive values mean edges are sharpened compared to the 
default settings, negative values mean that they are softened. Typical
 ranges are +1 to -1, but the supported range must be found using 
getPhotoCapabilities. If no sharpness control is implemented, the 
range is 0..0."

(this is NOT a concrete proposal, but an example of something that 
could make some claims of being independently implementable.)
