Good lighting makes budget gear look expensive. Bad lighting makes expensive gear look cheap. These basics cover most situations.
The three-point setup
Key light. The main, brightest light. Place it at roughly 30 to 45 degrees off-axis and slightly above eye level.
Fill light. A softer light from the opposite side. It lifts shadows. Make it dimmer than the key for contrast, or match it for a flat, bright look.
Backlight. Positioned behind and above the subject, it traces the edges of hair and shoulders, separating you from the background.
You can start with one light and a reflector, then add more as you learn.
Soft versus hard light
Softness depends on the size of the light source relative to your subject and its distance. A bigger source, or a source closer to the subject, makes softer light with gentler shadows. A small, distant source makes hard light with crisp shadows. Softboxes, umbrellas and diffusion panels make any light behave larger.
Color temperature
Daylight is about 5600K and tungsten bulbs about 3200K. Mixing sources of different color temperature creates odd color casts. Either match your lights or set your camera’s white balance manually and gel or switch off the odd one out. Bi-color LED lights let you dial the temperature.
CRI and TLCI
CRI and TLCI describe how accurately a light renders color. For skin tones and products, look for a CRI of 95 or higher. A cheaper light with low CRI can make skin look washed out or green no matter how you edit.
Choosing lights
- Power. Brightness specs are not comparable across brands, so read reviews and look for measured output.
- Control. Dimming and color temperature control save time on every shoot.
- Power source. Battery options help on location. Mains power helps in the studio.
- Mounting. Compatibility with stands, softboxes and your tripod setup matters.
Quick wins
- Face a window and let daylight be your key.
- Turn off mixed overhead lights.
- Add a white card or reflector for fill.
- Place a lamp behind you for separation.
Pair this with a steady tripod and an understanding of exposure and your results change fast.
Frequently asked questions
What is a three-point lighting setup?
It uses a key light as the main source, a fill light to soften shadows and a backlight to separate the subject from the background.
What CRI should video lights have?
Look for a CRI of 95 or higher for natural skin tones. Higher TLCI ratings serve the same purpose for video.
Is a bigger light always better?
Larger light sources create softer light. Brightness and size are different things, and a softbox makes a small light behave larger.
