Eventhough I'm using a large aperture lens to shoot a model in indoor and outdoor, the shoots looked either has digital noise(symptom of underexpose), color lack of vibrance/saturation/contrast and looks like the shoots need to have a reflector/flash.
I tried to meter the face just to make sure at least the face should be properly expose but it still show the same problem. Spot metering doesn't help. The problem would be solved if flash is used.
A lightmeter was used to double check whether there's any user error in metering.
So any idea?
