Hello

How can I focus a subject which is reflected in a mirror? What should I calculate?

Thanks!

Do it by eye or measure from the camera to the mirror and then to the subject.

Tom's got it. You have to account for the whole optical path to your subject.

If by eye make sure your diopter is properly set.

I guess nobody sets the diopter these days. And don't forget to plug the camera in when you shoot.

I recall my first mirror shot driving me nuts because it wasn't sharp through the lens when i measured.. turns out the diopter on the bolex wasn't set... and my whole roll, minus the mirror, was soft. Of course, you don't plug that camera in ;)

Well I did try to, but all that happened was a slight tingly feeling when I put my face to the finder.

I imagined that was it, measuring the whole optical path.
but i was confused cause someone told me once something
about the distance of the person to the mirror X2...

anyway, thanks for the good answer and for making me laugh while i read all the ramifications of the conversation!

That would be fairly correct if you were over the shoulder of the person, or standing right next to them shooting a single in the mirror.

hi,

as from my experience there are different types of mirrors - there are the ones where you measure from camera to mirror to actor and there are the other ones where you just measure from camera to mirror.
please don't ask me why - i don't know !
its just that i had it so many times in the last 13 years - just focus through the viewfinder and you will find out !
