Yes
Bit of a noob question but is there any model of camera that allows you to pick several focus points ie: subject 1 then subject 2 maybe 6 foot behind subject 1. Pretty sure the D5100 doesn't have that ability.
 
No, it's impossible. Just raise your aperture to get a large depth of field.
 
Actually, it's not only possible but many cameras have implemented it. Well, not exactly what Nick wants, but close. Canon call it A-Dep mode. It looks at all the focal points, figures out the nearest and furthest then sets the aperture so that the DoF covers the whole range. LINK
 
No it's impossible.. Setting a large aperture to obtain a large depth of field and using more than 1 focal point on a different focal plane is very different.
 
Well, there's the Lytro.

So the technology exists but probably not at the quality we need just yet.

ETA: And it's not mainstream though you can buy them.

But that's just what A-Dep does, it uses more than one focal point on a different focal plane to determine the aperture required to give sufficient DoF to cover both focal planes.
 
The reason I asked is I got married yesterday and the tog either focused or metered off us both before each shot. She was using a 5d2 at the time so I shall ask her when we meet next. Not much time to get into equipment chat at my own wedding lol..
Thanks for the replies:)

She was establishing the brighness range, one from the white dress and one from the dark suit. It can also be useful to check if the skin colours are very different, so as to expose them well. Sounds like she knew what she was doing.

Not sure I would be on the forum if I was married yesterday....Exposure would not be high on my priorities. Though focus might be.

Last couple days have been a blur but we had loads of friends round today and everyone looking at their own photos which gave me 10 mins to jump into the forum.

Brightness range! now that makes sense...
Thanks for the reply:)
 
Yup, think about it, the bride has a bright white dress with fine lacy details so accurate exposure is important as the bride will have spent a lot in both money and time/emotions on that dress. Then right next to her is usually a groom in a dark suit, so a huge dynamic range for the camera to deal with.

Anyhow - enjoy your honeymoon :D
 
Madeira next week but under threat of spending too much time taking photos😞 Will be more memory shots than looking for arty shots.
