lets say now im going for macro , me and my brother going there he is with flash im without , now i can see that his macro in terms of color look slightly cooler but also more real , so how can i tweak it to be more accurate color ? cause i dont want to go with grey card to any place i will be , so what you suggest changing at the WB for it to be more accurate? BTW ( im not saying the color are not good they are different and more warm )
