Question 1

Can WhiBal be used for determining exposure as well as White Balance?  If so, what is its reflectance?  18% or 12%?

Accepted Answer

WhiBal is not designed for exposure. it is neither 18% or 12% as those are too dark for optimal White balance setting. We have a luminance value of 75% as opposed to the 50% of an 18% gray card which might not even be optimized for neutrality which is essential for proper White balance. Michael Tapes

Question 2

Rather than holding a piece of white paper up, can I use this card to set the custom white balance in my Nikon D60 (even though the card is grey)?

Accepted Answer

Yes and much preferred. The white piece of paper is normally not neutral and therefore is not an accurate White balance reference. The "Gray" tone of the WhiBal is measured (each card) to be 99.9% neutral, and the tone is designed for optimal White balance resolution as well.

Question 3

I bought one and it's giving way wrong kelvin like 10000-11000 instead of 6500k when using flash outdoors. is something wrong with it?

Accepted Answer

I have not been able to use this thing after watching videos on YouTube and the WhiBal video.  If you figure out how to use it, could you do a video for YouTube?  If I do, I'll make one too.  It feels stupid to not know what to do with it or how it's supposed to help.  I had great faith in it when I bought it, full of hope that I'd finally have a key to White Balance that would be quick and easy.  I'm back to shooting a white piece of paper to get a pre-set for current situations.  I wonder if this answer will give rise to more information...thanks for asking.

Question 4

What does the back of this card look like?
