Sure :)
ok for example if I shoot someone setting in front of a door or 3 to 4 feet away from the door
the person will be in focus but the door will be blur like the depth of field is waaaayyy to short..
because I want the doors detail as well... in A-DEP mode it always gets the person and the door and anything around it in focus as well as the person im shooting.. and I would shoot like that.. but A-Dep does not allow me to use flash for some reason :-)

i just want as much detail as possible of the person and the persons surounding as well :-)

if I use A-Dep to choose the depth of field and then jump over to manual and put it in that way.
it dont work to well in low light.. because it tells me shutter speed is like 2'' and apature is like 4.3
because A-Dep has no idea I have a flash hooked up

so when I jump to manual the shutter is set to 250 and the apature will only let me go as low as 5.6
