I have a '5 Way Reflector' that I want to use in my photography, which includes the following 5 options: Gold reflective Silver reflective Gold/silver alternating pattern reflective White ...
I want to use a piece of fabric as an inexpensive reflector. Is there any way to find out if it is pure white, so that I can be sure it will not add a colour cast to the light it reflects?
