Digital gray card

Bringing you this site is my full-time job typically hours per week. Or a white person in winter time with little sun exposure? Udi Tirosh is the Founder and Editor in Chief of DIYPhotography, he is also a photographer, a relentless entrepreneur, a prolific inventor and a dad, not necessarily in that order. Both approaches will not give you ANY reasonable results. If you have a surface large enough, then you can set your custom WB quite easily using your digital WB cards.
