This is a product review for the Vello Universal White Balance Handheld Disc. White balance is something that I constantly tweak in Photoshop. I typically use the auto white balance function on my Canon 5D Mark III. I find that the auto function gets my white balance close, but in post production I typically adjust the white balance sliders a little to get my final edit.
I was curious and eager to know if a white balance tool would help me get it closer in camera.
