How far does a standard camera flash project?

• A. 3-5 feet.
• B. 15-20 feet.
• C. 9-12 feet.
• D. 30-40 feet.

Answer: (C)

Light from a standard on‑camera flash weakens with distance, following the inverse-square law. For a typical portrait setup at normal indoor ISO and aperture, the flash provides a usable amount of light enough to illuminate a subject best when they’re about nine to twelve feet away. This distance offers a good balance: the light is strong enough to render the subject clearly without becoming so harsh as to flatten features, yet not so far that exposure falls off and details dim. If you move closer, the light can become overly bright and cause harsh shadows or overexposure; if you move farther, the subject may appear underexposed unless you compensate by raising ISO, widening the aperture, or using a flash with more power or a bounce/diffuse lighting technique. So nine to twelve feet is a practical range for a standard flash to project effectively in typical shooting conditions, with adjustments possible based on power, reflectivity, and how you’re using the flash.
