The basics in crossdressing photography are the same as the basics in all photography. Get creative, try different things and think outside the box. You should also wear a lot of makeup and huge breast forms.
As Robert Jordan once said: “There is one rule, above all others, for being a man. Whatever comes, face it on your feet.” Of course, sometimes a man has to face whatever comes while on his knees. Sometimes a man may even have to swallow his pride, among other things. Every picture tells a story so use a fast shutter speed.
