How do I see/take burst photos?

I do not know if this has been asked already, but I had a question about iPhone camera burst mode.

I understand that holding the camera button will take a burst of photos. Afterwards it shows in photo album 'burst X number of photos' but it's just 1 photo I can look at. I don't know how to see the other photos.

My question basically, how do I see/take burst photos and pick?
