* The look you're going for: Softer vs. more contrasty light
* Your subject: Headshots vs. full body
* The distance you can work from your subject: Smaller studios need smaller dishes
* The power of your strobe: Larger dishes eat more light
Here's a general guideline to help you decide:
16-22 inch Beauty Dishes
* Best for:
* Headshots and tight portraits: These sizes are ideal for creating a beautiful, focused light on the face.
* Small studios or limited space: They don't need a lot of working distance.
* More contrasty light: Produces a slightly more contrasty and focused light due to the smaller surface area.
* More portable: Easier to travel with.
* Considerations:
* May be too small for full-body shots or larger groups.
* The sweet spot for sharpness is smaller, so you have to be pretty accurate with positioning.
23-28 inch Beauty Dishes
* Best for:
* Versatile portraits: A good balance between softness and contrast. Suitable for headshots, waist-up, and even some full-body shots.
* Medium-sized studios: Provide a good balance of spread and control.
* Softer light: Creates a more diffused light compared to smaller dishes.
* Most popular size: A good starting point if you're unsure.
* Considerations:
* May require more working distance.
30+ inch Beauty Dishes
* Best for:
* Full-body shots and larger groups: The larger surface area provides a wider spread of light.
* Softer, more flattering light: Ideal for minimizing blemishes and creating a smooth, even skin tone.
* Larger studios: These require a significant amount of space.
* Considerations:
* Can be less directional, leading to less defined shadows.
* Requires a powerful strobe to generate enough light.
* Less portable.
* Can be unwieldy to handle.
Key Considerations and Additional Tips:
* Light Quality: Remember that beauty dishes provide a unique light quality that falls between hard and soft light. The size primarily influences the degree of softness. Larger dishes generally offer softer light, while smaller dishes produce a more contrasty and defined look.
* Accessories: Consider using diffusion socks or grids with your beauty dish. Diffusion socks soften the light even further, while grids control the light spread and prevent spill.
* Distance: The distance between the beauty dish and your subject significantly affects the light quality. The closer the dish, the softer and more enveloping the light. The farther away, the harder and more specular the light.
* Testing: Experiment with different sizes and distances to find the combination that best suits your style and subject.
* Budget: Beauty dishes can range in price. Consider your budget when choosing a size and brand. A good quality, reasonably-sized beauty dish (22-28") is usually a good investment.
* Placement: Beauty dishes are typically positioned slightly above and in front of the subject, angled downward. This placement creates a flattering light with soft shadows.
* Material: While less critical than size, the material of the beauty dish (white, silver, gold) also impacts the light. Silver is brighter and more specular, white is softer, and gold adds warmth.
In summary:
* For starting out: A 22-28 inch beauty dish is a good all-around choice.
* For mostly headshots and tight spaces: 16-22 inch dishes are ideal.
* For mostly full-body and larger spaces: 30+ inch dishes are a better fit.
Ultimately, the best size beauty dish for portraits is a matter of personal preference and depends on your specific needs and style. Don't be afraid to experiment and see what works best for you!
