Technical Support / Distance from subject question
« on: April 11, 2013, 09:38:00 AM »
I'm having a senior moment here and need a formula.
I want to take a mirror image of a church steeple using 24x48 piece of black acrylic as the mirror...let's assume that the steeple is 200 ft tall.
How far from the steeple do I place the mirror to fill that mirror with the steeple...like I said, just need the distance/size relationship formula. Thanks
