Lets say I am taking a big group picture how would I make sure that it is focused on everyone?
where would I put my AF point on?
and how high of a F stop?
focus on people on front row
depend on how big group, distance, what you want in focus..etc
so for people that are further away are you supposed to increase the f/stop number?
this might hellp
chances are if all the people in the group are standing side, by side, and the photographer is facing them, they are all generally in the same plane of focus.
you don't need an extremely small f/stop to get them all in focus.
they are side by side for the most part. Maybe 3 feet apart tops.
I shot it in f/3.5 and it's usable for if I wanted to blow it up, the image wouldn't be so sharp.
o and I ran into the front of the group before the timer went off. I am thinking that may have fucked up the focus.
pre-focus onto the person in the middle. set camera on manual focus mode. set timer to 10-15sec. shoot at f/5.6-f/8 and you will probably be safe
What about the d80 pack to go with the heads?
f3.5?? For portraits?
You should be shooting that somewhere between 7.1 and 11, depending on where whatever lens you're using is sharpest.
The image will be sharper, and the depth of field will be deeper.
almost every lens is sharp by f/8
so I should raise the ISO to take a picture at f/8 for the highest pq?
Nobody said anything about ISO. If it's an outdoor portrait I would use somewhere around 200 ISO, indoor maybe a bit higher. Put your camera on aperature priority and set it anywhere from 8-11.
When you have your aperature set at like 3.5 your depth of field (area in focus) will be too short to have 2-3 rows of people completely in focus. Set it higher and your problem will be fixed.
does the 8-11 rule apply for all lenses?
even primes and constant 2.8 lenses?
The general rule is that a lens is sharpest 2-3 stops up from it's max aperture.
A good part of the reason people use 1.4 and 2.8 lenses for portrait work is because you are able to work around 4-5.6 and get the subject perfectly focused, good enough depth of field to blur the background, and great sharpness.
But if your min. aperture is 3.5, then you're gonna be getting sharp around 5.6-8. and if you need more DOF to get everyone in focus, 8 would be the smart choice...
Like jared just said, it depends on the lens. If you have a prime lens that is constant 1.8 you can get a sharper picture at a lower aperature than say a constant 5.6 lens or something similar. It takes a little experimentation, but generally if you want a deeper depth of field set your aperature a few stops higher than you would for that exposure, and if you're in aperature priority your camera will compensate by taking a longer exposure.
And is matrix metering recommended for a group shot?
most of my shit is sharp by 2.8
On a side note: jared gives good advice.
