I have posted quite a few times on these forums now, so I return to you again with more questions. I have been photographing for about 3 years now and haven't been able to stop since i picked up the camera. I started going to school for photography earlier this year, and the vast amount of informations I have learned in that short time is just a drop in the bucket to what the industry has to offer. To the point: I bought an SB-600 flash last night for my D90, I love it so far but realized I dont know the first thing about using this flash on my camera or off (I do know how to make it fire off camera but thats about it) I am wondering if you all on these forums can recommend some books and or websites where I can learn about lighting and how to use my flash. It will be about 6 months before I can take the studio class at my school and I dont want to wait that long to learn. Thanks in advance for all of your help!
