Studio Lighting Calculator
Calculate lighting ratios, power settings, and distances for multi-light studio setups
About this calculator
The Studio Lighting Calculator helps photographers and videographers calculate precise lighting ratios, power settings, and optimal distances for professional multi-light setups. This tool eliminates guesswork by providing accurate measurements for key lights, fill lights, and background lights, ensuring consistent exposure and desired contrast ratios. Whether you're shooting portraits, products, or commercial photography, this calculator streamlines your lighting workflow and helps achieve professional results with mathematical precision.
How to use
Enter your desired lighting ratio (such as 2:1 or 4:1) and the power of your key light. Input the distances between your lights and subject. The calculator will automatically determine the required power settings for your fill lights and background lights to achieve your target lighting ratio and optimal exposure balance.
Frequently asked questions
What is a good lighting ratio for portrait photography?
A 2:1 or 3:1 ratio works well for most portraits, providing natural-looking contrast without harsh shadows or overly dramatic effects.
How does distance affect lighting power calculations?
Light intensity follows the inverse square law - doubling the distance requires four times more power to maintain the same exposure.
Can this calculator work with different types of studio lights?
Yes, it works with any studio lights including strobes, continuous LEDs, and tungsten lights, as long as you know their power ratings.
