I really like those blastos as well
I set the camera to prioritize shutter speed because otherwise the shutter stays open for a second + resulting in a blurry picture when shooting my hand.
Instead of messing with the other camera setting for white balance, I have found that using Lightroom for post processing to be much more efficient. Some people don't understand that Lightroom does much of the same functions as your camera does to white balance/saturation ect, just in a easier and quicker way on your computer. All pictures are processed, either by the camera and its software or on a computer using software. All this is assuming you are shooting in RAW format.
