Group photo focusing?

Hello,
I have several friends coming over, today. So, I want to take a group portrait. How will I get everyone in focus? I thought about focusing on the closest person, and stop down to f 5.6 or f 8 to get the others in focus. Will that work?

The aperture needed depends on the setting, but the general idea is right. If having a lot of rows maybe focus on the second row rather than the first one.
And remember to use a bit of spray n pray, you need luck to have everybody with two open eyes etc.

Hey so you've got the right idea but there's a fair bit that goes into this:

- The wider the lens the higher your depth of field for any given aperture
- Standing 1 metre farther away can almost double your depth of field
- When you pose people, ensure you don't pose them in a way that makes the closest and furthest subject eyes too far apart. When I do groups, and when others do, we ask them to stand diagonally so that we get a fairly consistent distance and can reduce the number of rows as we can now cram more people into each row

But to be honest focal length really is the big one here. To give you an idea, standing 4m away and shooting at f8 you would get a depth of field of 3.5m (when using a 50mm lens) and a depth of field of 15m (when using a 35mm lens).

Use this calculator and you can't go wrong

Most of all, enjoy the shoot!

Depends on the distance from camera to subject. have a look at an online DOF calculator like these ....

I see you mentioned that it is only three people, which increases your odds of getting all open eyes, My answer is more general in nature, but make sure that you line them up how you want to. That is very important, people have no clue in composition of the photo, and they will go to positions that will make a barely acceptable photo impossible. If there is a backdrop, by this I mean any type of object or feature that has to be in the picture, you'll have to position them there also. If the object is behind them, be careful with shadows, mostly keep the photo balanced. If you have time, pre-mark the spots where you want people to be and position for lighting. Once you have people where they need to be, I recommend eyes of the center person as your target. And as you already said, try to get as much DOF as possible. If the photo is indoors, or outdoors facing the sun, consider a little flash to freeze eye action, take a couple with flash, a couple without.

Set the aperture to f5.6 then shoot in live view and use the face recognition focus feature. It should be perfect.

If you want to focus through the viewfinder, choose your auto focus point and set it for the eyes of the person who seems closest to the camera.
