New to the introduction...

so i have been a member of the site for quite some time but just don't have a lot of time to chat because of work and other obligations. but hey to all and love the site... my favorite forum is the pictures section and newbie growing area! so basically i wanted to take some pics of my bud because i have been raving about it but havent posted any pics. i have a sony cyber shot and cant figure out how to take good macro shots? anyone know how to turn off the flash? thanks bros and girls!!!
