Challenge Problems
Push your limits with challenges.
Question 1
You have a photograph taken at a flying height of 1500 m using a camera with a focal length of 75 mm. Calculate the scale of the photograph and discuss how it might change if the average elevation of objects in view is raised by 20 m.
💡 Hint: Recalculate with adjusted height; elevation will always make scale change.
Question 2
Consider two points on differing elevations, point A at 15 m and point B at 25 m above sea level. Calculate their respective scales if photographed from a height of 1000 m with a 50 mm lens.
💡 Hint: Do each calculation separately and notice how their differences arise from their heights.
