Q: Can you take a photo when using face time ??

I would have to say no. You are essentially on a phone call with FaceTime, so you would have to end that call to access the camera app.

Are you trying to get a screen capture, or are you trying to take a picture and send it?

EDIT: I just tried and was able to get a screen capture.

Try it and find out

I just tried it and it worked.

Yes, you tap them both like a camera shutter button. You can try it out any time before you get on FaceTime, then you will be ready. The pictures go into your camera roll in the photos app.
