Photography Flash Power & Modifier Selector for Studio Portraits

Select flash power, modifier type, and placement for studio portraits based on subject, lighting style, and room size to achieve soft, flattering light without harsh shadows.

‍

Perfect for studio portrait or beauty photographers.

‍

We ask for flash type, portrait style, number of lights, modifier preference, room size, flash power level, and current issue because these create flattering light (e.g., large softbox at 45°). These inputs control shadows and highlights. Limitation: the tool uses general lighting ratios; exact power depends on distance, modifier size, and ISO, always meter and adjust.

Studio Flash Selection for Portrait Lighting

Recommended Setup

1. General Recommendations

• Power: Use a speedlight with a power setting of 1/4 to 1/2. This range will provide enough power to create soft, flattering light while preventing overexposed highlights.
• Modifiers: Utilize a shoot-through umbrella to diffuse the light, creating a soft and beautiful effect on your subject’s skin.
• Placement: Position the key light at 45 degrees to the side and slightly above the subject’s eye level. The fill light should be placed at a lower angle and closer to the camera, at about 30 degrees.

2. Light Ratios and Feathering

• Light Ratios: Aim for a key-to-fill ratio of 2:1 to achieve a balanced look without harsh shadows. This means if your key light is set at 1/4 power, your fill light should be around 1/8 power.
• Feathering: Feathering involves angling the light source so that it illuminates the subject without hitting them directly. This technique softens shadows and creates a more natural look. For the key light, angle it towards the subject's cheek, allowing light to spill onto the background for depth.

Setup Examples

Setup 1: Classic Beauty Shot

1. Key Light:
   • Position: 45 degrees to the subject
   • Modifier: Shoot-through umbrella
   • Power: 1/4
2. Fill Light:
   • Position: 30 degrees in front of the camera
   • Modifier: Shoot-through umbrella
   • Power: 1/8
3. Background: Consider using a neutral background to allow the subject to stand out.

Setup 2: Dramatic Portrait

1. Key Light:
   • Position: 45 degrees to the side and slightly above the subject
   • Modifier: Shoot-through umbrella
   • Power: 1/2 (to create more impact)
2. Fill Light:
   • Position: Closer to the camera, slightly below eye level
   • Modifier: Shoot-through umbrella
   • Power: 1/4 (to maintain a softer feel)
3. Background: Use a slightly darker background to enhance contrast.

Conclusion

This approach will give you clean, beautiful results while keeping highlights controlled. Experiment with placement and ratios to find what works best for your style.
