Measuring

Is there any kind of software or device for measuring the height of something (that you can’t get close to) in a photo? Or is the only way to place something you know the exact height of next to it? Hope that makes sense.

For more on marking an answer as the "Best Answer", please visit our FAQ.You need to know the horizontal distance from where you are measuring to the foot of the object; then you need to know the angle between the horizontal and the top of the object, then you need to know the vertical distance between your eye and the bottom of the object. A clinometer (Home-made or bought) can tell you the angle and then you work it out by trigonometry. I doubt if any software could give you an answer simply by showing it a photograph.
