YAY lets all bash the new person...
Instead of telling them what not to do, lets tell them why they should do it the way you think it should be done.
Tips:
Ok so when you come onto onto a forum try and be as specific as possible, tell us your equipment, what you want to get out of the shoot and any other information relevent.
now depend ending where you are in the world 6 may be dark or still quite bright...
You need to have 1 (or more) reflectors in place to fill shadows
An external flash to use as fill is important-use with a defuser or or bouncing it on something otherwise the light could be to harsh (my on board camera flash is not great and I have a nice 30d)
Dont shoot Auto, your camera's brain will be trying to work out the shutter speed and aperture for you, plus it will set your ISO for you, this can result in grainy pictures. If your camera chooses a slow shutterpeed if your subjects move or your camera moves your image will get blurred-this will be aparent just from hitting your camera button as the downward pressure will shake the camera. I could go on....
If its a new camera and you are learning then I asume that you are using the photoshoot as practice and you are not gettting paid for it, so if you mess the pictures up while using AV TV or M mode dont worry-its suposed to be fun while you learn.
For poses dont cut lims off at joints and you will be fine...
The reason people get angery on the forum when people start to call them selves photographers, and start charging for pictures taken on auto or P mode with minimal equipment is because They put in alot of hard wotk to become good at what they do, pictures taken on custom settings are a world apart in quality when used correctly. so if someone is using a DSLR on auto and getting paid, the work is likely to be substandard, which in turn can give photographers a bad name. There are lots of reasons tooo.
Oh and I have been shooting manual since April with my camera and before that a year with my old camera (advanced point and shoot) and I am not ready to go out and get paid even though I have done practice shoots because I want to go out equipped with the best knowledge and take amazing shots that are worth the money that the clients paid for them-this time next year, hopefully thats where I will be
Last thing-post your pics when your done so we can advise you for your next practice
