An aerial camera has a 9½-inch square film format and a 6-inch focal length lens. What must the flying height (in meter) be to obtain a scale of 1/2000? (Hint: 1 inch=2.54 cm)

Expert Solution

ANSWER

STEP 1

Given that focal length of the camera lens (f) = 6 inch = 6 *2.54 cm = 15.24 cm

Scale (S) = 1/2000 ( or it can also be written as 1 : 2000)

Let H be the flying height

Step 2

We know that

f/H = S

or, 15.24/H = 1/2000

Or, H = 15.24 *2000 =30480 cm

= 304.80 m

Therefore the required flying height (in meter ) is 304.80 meter

A simple camera telephoto lens consists of two lenses. The objective lens has a focal length f1 = 38.7 cm . Precisely 36.3 cm behind this lens is a concave lens with a focal length f2 = -10.0 cm . The object to be photographed is 3.97 m in front of the objective lens How far behind the concave lens should the film be placed? What is the linear magnification of this lens combination?

A camera lens has a focal length of 100 mm (thick lens). The photographer first adjusts the location of the lens to look at an object very far away (infinite distance). Then he tries to take a picture of a person 2 meters away from the lens. How is he going to adjust (move) the lens relative to its original position? What is the distance of the adjustment?
