Can someone please explain what Macro Photog is? What do you need to do it, how can you achieve it, does it require photoshop enhancements???? I keep hearing about it and I want to know what it is. I have also seen pictures and I am dying to try it. Is it achievable with my Canon Rebel XTi? What lens would I use?:hail::hail::hail: I need to know EVERYTHING pleaseeeee!
