The question is:

Can you photograph yourself in a mirror and focus the camera on both your image and the mirror frame? Explain.

I tried it for myself and it's possible, but I just can't explain why.

  1. Another question related to this that I can't figure out is:

    If you take a photograph of your image in a plane mirror, how many meters away should you set your focus if you are 2 meters in front of the mirror?

  2. No, actually you can't perfectly focus the mirror's frame and your own image. Your image is twice as far from the camera as the mirror.

    For the reason i have just stated, for your second question, you should focus for 4 meters away to have yourself in focus.

    Most digital cameras sold today would autofocus to the correct distance anyway.
