Here's my question! Can u use them together? I mean, if I use the spot metering while adjusting my exposure with my grey card, is it going to mess up the settings? I'm asking cos I took some shots yesterday with the center weighed metering mode while adjusting with the grey card and the shots were awful!!! all the shadows were just black! No details at all! Although, my subject was dressed all in black and I'm wondering if I should have had increased the exposure by 1 stop? Not quite sure how to use the grey card yet! Any advice plz!? Although, is the grey card to be used in every occasions or just in difficult lighting situations or what!? Cos so far, I've had better results without using it! O_o Weird!! Help plz!
