SUMMARY

The discussion focuses on calculating the Field of View (FOV) using a practical method involving photography. The user describes an experiment where they photographed a wall, adjusting the distance from the camera to the wall, and conceptualized the scenario as an equilateral triangle. By measuring the wall's size and the distance to the camera, they calculated the tangent of the half angle, doubled it to find the full angle, and concluded that this represents the FOV. This method is valid and demonstrates a hands-on approach to understanding FOV without knowing the camera's focal length or frame size.

PREREQUISITES
  • Understanding of basic trigonometry, specifically tangent functions
  • Familiarity with photography concepts, including focal length and frame size
  • Knowledge of geometric principles, particularly triangles
  • Experience with practical photography techniques and measurements
NEXT STEPS
  • Research "Calculating Field of View in Photography" for more detailed methodologies
  • Learn about "Camera Focal Length and its Impact on FOV" to deepen understanding
  • Explore "Geometric Principles in Photography" to apply mathematical concepts effectively
  • Investigate "Using Photography Apps for FOV Calculations" to utilize technology in measurements
USEFUL FOR

Photographers, videographers, and anyone interested in understanding and calculating the Field of View in various imaging scenarios.

Hi.thanks about my question on focal length.you were really helpful.Another question now about Field of view. I know that it is a angle showing a triangle.inside the area of the triangle any object can be photographed .a i right?i know tha it is not a scientific explanation iam just saying what i haveunderstood.

i have a camera. I do not know the focal length nor the frame size.i want to calculate the FOV.listen to what i thought.i did an experiment.i was taking photos of a wall withbricks soas to be able to calculate the size of the wall i was phtographing each time.at each phot i was changingthe distance between the camera and the wall. i imagined a equilateral triangle.the base is the size of the wall.the height is the distance between the camera and the wall. from there i calculated the tan of the half angle of thetriangle.then i found the half angle , multiplied it by two and i found the whole angle of the triangle. i think this is the FOV.am i right or i have done sillu things?thank you very much

Sounds good to me asa, after a number of pints.
 
i wrote it again because at the first message i had done many mistakes .sorry
