Key Factors Affecting Beauty Dish Size Choice:
* Distance to Subject: The closer the subject is to the light source, the softer the light appears, regardless of the beauty dish size.
* Desired Softness/Hardness: Larger beauty dishes produce softer light with broader highlights and less defined shadows. Smaller beauty dishes create harder light with more defined shadows.
* Coverage Area: Larger beauty dishes offer broader light coverage, making them suitable for full-body portraits or groups. Smaller beauty dishes concentrate the light on a smaller area, ideal for headshots or close-ups.
* Studio Size: Consider the size of your studio. Larger beauty dishes require more space to maneuver.
* Portability: If you're shooting on location, a smaller, more portable beauty dish might be a better choice.
Beauty Dish Sizes and Their Characteristics:
* 16-17" Beauty Dish (Small):

* Best For: Soft, flattering portraits, minimizing skin imperfections, full-body shots where you want a softer light.
* Distance to Subject: Works well at a greater distance (6-8 feet).

Tips for Choosing the Right Size:
* Start with a 22" Beauty Dish: This is a versatile size that works well for a variety of portrait styles. You can always add grids or diffusion to modify the light further.
* Consider Your Subject Matter: If you primarily shoot headshots, a smaller beauty dish might be ideal. If you shoot a lot of full-body portraits, a larger one would be better.
* Think About Your Style: Do you prefer a more dramatic, high-contrast look, or a softer, more flattering look?
* Experiment: If possible, try renting or borrowing different sizes of beauty dishes to see which one you prefer.
* Modifier Compatibility: Ensure any grids or diffusers you plan to use are compatible with the size you choose.
Grids and Diffusion:
* Grids: Attach to the front of the beauty dish to narrow the beam of light and reduce light spill. This increases contrast and adds more directionality to the light.
* Diffusion Socks or Fabrics: Soften the light further, making it more forgiving on skin and reducing harsh shadows.
In summary:
* Small (16-17"): Dramatic, defined, close-ups.
* Medium (20-22"): Versatile, good balance.
* Large (27-28"): Soft, flattering, wider coverage.
* Extra Large (30"+): Very soft, large groups/full body, commercial use.
Ultimately, the best size beauty dish for portraits depends on your individual needs and preferences. By understanding how size affects the light, you can choose the option that will help you achieve the look you're after.
