  1. In Energy Service Company, what is the "exposure triangle" in photography?

    Answer: The relationship between aperture, shutter speed, and ISO

    The exposure triangle describes the three variables that control the amount of light reaching the camera sensor: aperture (lens opening), shutter speed (exposure duration), and ISO (sensor sensitivity).

  2. What does aperture control in Energy Service Company?

    Answer: The size of the lens opening, affecting depth of field and light intake

    Aperture controls the size of the lens opening (measured in f-stops). A wider aperture (lower f-number) allows more light and creates shallower depth of field; a narrower aperture increases depth of field.

  3. In Energy Service Company, what is "depth of field"?

    Answer: The zone of acceptable sharpness in front of and behind the focused subject

    Depth of field is the range of distance in a photograph that appears acceptably sharp. It is controlled primarily by aperture, focal length, and subject distance.

  4. What is white balance used for in Energy Service Company?

    Answer: To ensure accurate color reproduction by compensating for the color of the light source

    White balance adjusts the camera's color processing to compensate for the color temperature of different light sources (daylight, tungsten, fluorescent), ensuring whites appear truly white and colors are accurate.

  5. In Energy Service Company, what is the difference between RAW and JPEG file formats?

    Answer: RAW preserves all sensor data for maximum editing flexibility; JPEG is compressed with some data loss

    RAW files contain all data captured by the sensor, providing maximum flexibility for post-processing. JPEG files are processed and compressed by the camera, resulting in smaller files but with some data loss.

  6. What is the purpose of "bracketing" in Energy Service Company?

    Answer: Taking multiple shots at different exposure settings to ensure optimal exposure

    Exposure bracketing involves taking several photos of the same scene at different exposure levels (underexposed, correctly exposed, overexposed) to ensure at least one has optimal exposure or for HDR processing.
