* Shooting Style/Look: Do you prefer soft, flattering light or a more contrasty, defined look?
* Subject Distance: How close or far away will you be from your subject?
* Full Body vs. Headshots: What portion of the body will be in the frame?
* Studio Size: How much space do you have to work with?
* Power of Your Lights: Will the light be powerful enough to use a large modifier?
Here's a breakdown of common beauty dish sizes and their effects, plus recommendations:
Common Beauty Dish Sizes and Their Effects
* Small (16-22 inches):
* Light Quality: Creates a more contrasty and focused light. Highlights are more pronounced, and shadows are deeper. Still softer than bare flash, but with more "pop".
* Falloff: Light falls off quickly. This means the light is brighter closer to the center and drops off faster towards the edges.
* Subject Distance: Ideal for tighter headshots or when you want to emphasize texture and detail. Works well when you want a more dramatic look.
* Use Cases: Beauty and fashion headshots, portraits where you want to accentuate facial features, creating a more edgy or dramatic feel.
* Pros: Portable, easier to handle, can be used in smaller spaces.
* Cons: Can be too harsh for full-body shots, light falloff can be uneven if not positioned correctly. Might require more precise positioning.
* Medium (23-28 inches):
* Light Quality: A good balance between soft and contrasty. Offers a more flattering light than smaller dishes, but still provides definition. The "sweet spot" for many portrait photographers.
* Falloff: More gradual falloff than smaller dishes. Easier to achieve even illumination.
* Subject Distance: Versatile. Works well for headshots, 3/4 shots, and even full body shots with careful positioning.
* Use Cases: General portraiture, beauty, fashion, headshots, and lifestyle. A great all-around choice.
* Pros: Versatile, provides a good balance of softness and contrast, easier to work with than larger dishes.
* Cons: Might be slightly less portable than smaller options.
* Large (29-36 inches and above):
* Light Quality: Produces a very soft and even light. Highlights are diffused, and shadows are subtle. Mimics the effect of a larger softbox, but with the characteristic beauty dish highlight.
* Falloff: Very gradual falloff. Creates very even illumination, even on full body shots.
* Subject Distance: Best for full-body shots, group shots, or when you want a very soft and flattering light across the entire subject. Needs a larger space to operate in.
* Use Cases: Full-length fashion shots, group portraits, softening wrinkles and skin imperfections, creating a very natural and gentle look.
* Pros: Provides very soft and even light, great for full body shots, forgiving in terms of positioning.
* Cons: Can be cumbersome to handle, requires a powerful light to fill effectively, needs a larger studio space. Can reduce the specular highlight and pop of the image if you don't use a powerful enough light.
Recommendations
* Beginner/All-Purpose: 22-28 inches is the best starting point. It's versatile enough to handle a variety of portrait styles and shooting distances without being too difficult to manage.
* Headshots/Beauty: 16-22 inches if you want more contrast and detail.
* Full Body/Soft Light: 28-36 inches (or larger) if you prioritize soft, even illumination and have the space and power.
* Small Studio: 16-28 inches to maximize your space and portability.
Important Considerations:
* Deflector (Silver vs. White):
* Silver: Creates a brighter, more specular light with higher contrast.
* White: Produces a softer, more diffused light with less contrast. Often preferred for portraits. The interior coating color impacts the light quality.
* Grid: Adding a grid to your beauty dish narrows the beam of light, reduces spill, and increases contrast. Useful for controlling the light and preventing it from hitting unwanted areas. Consider this for small to medium sized beauty dishes.
* Sock (Diffuser): A diffuser sock can be placed over the front of the beauty dish to further soften the light. Useful for achieving an even softer look than the beauty dish alone.
* Distance: The closer the beauty dish is to your subject, the softer the light will be. The further away, the harsher and more contrasty.
Before Buying:
* Consider Renting: If possible, rent a couple of different sizes to experiment with before committing to a purchase.
* Read Reviews: See what other photographers have to say about specific brands and models.
* Budget: Prices can vary significantly. Factor in the cost of the beauty dish itself, a speedring (if required to attach to your light), and potentially a grid or sock.
By considering these factors and understanding the characteristics of different sizes, you can choose a beauty dish that suits your shooting style and helps you create beautiful and flattering portraits. Remember experimentation is key to finding what works best for you!
