Re: How to achieve 'perfect' whites in Hi Key?

In this example it looks more like a case of slight underexposure.

A white background that is further away from the subject will appear darker than the subject that is exposed correctly if it is lit by artificial light , this is called light fall off or the inverse law. Normally in a studio /controlled light situation lighting the white background 2 stops more than the main subject will ensure a completley shadowless and white background.

In this case simply using levels and the white point eyedropper on the background does the trick.
