Common Beauty Dish Sizes:
* 16" - 17" (Small): These are the smallest and most portable.
* 20" - 22" (Medium): A very common and versatile size, often considered a good starting point.
* 27" - 28" (Large): Provide a larger, softer light source.
* 30"+ (Extra Large): Produce a very soft, wrapping light.
Key Factors to Consider:
* Subject Distance: How close will you be to your subject?
* Desired Light Quality: Do you want more contrast and specularity (highlights), or softer, more diffused light?
* Portability: Will you be shooting on location or in a studio?
* Your Studio Space: Do you have enough room to maneuver larger modifiers?
* Budget: Larger beauty dishes often cost more.
* Subject Size: A larger dish can be more flattering for full-body portraits or group shots.
Size Breakdown and Their Effects on Light:
| Size | Light Quality | Best For | Subject Distance | Pros | Cons |
|--------------|-------------------------------------------------------------------------------|---------------------------------------------------------------------------------------------------------------------------------------------|---------------------------------------------------------------|---------------------------------------------------------------------------------------------------|-------------------------------------------------------------------------------------------------------------|
| 16-17" | Harsher, more specular highlights, faster falloff. | Close-up portraits, headshots, adding drama and definition. Good for smaller spaces. Can emphasize skin texture. | Very close (1-3 feet) | Portable, affordable, creates defined features, good for small studios. | Can be too harsh on skin, fast falloff may require careful placement, not ideal for full body. |
| 20-22" | Balanced - good mix of highlights and soft light, versatile. | All types of portraits (headshots, half body, 3/4). Considered a good "general purpose" beauty dish. Flattering for most skin types. | Close to medium (2-5 feet) | Versatile, good balance of soft and hard light, relatively portable. | May not be soft enough for some tastes, can still show some skin texture. |
| 27-28" | Softer light, gentler highlights, slower falloff. Wraps around the subject more. | Beauty and fashion, softening wrinkles and imperfections, creating a more flattering overall light. Good for minimizing skin texture. | Medium to further (3-7 feet) | Soft, flattering light, forgiving on skin, good for full-body shots. | Less portable, requires more space, can be expensive, may need more power from your strobe. |
| 30"+ | Very soft light, minimal highlights, very slow falloff. | High-end beauty and fashion, creating a very smooth, even light. Often used with diffusers for even softer results. | Further away (5+ feet) | Creates a very soft and flattering light, minimizes skin texture, very forgiving. | Least portable, requires significant space, expensive, may require a powerful light source, can flatten features if not used carefully. |
Key Considerations Explained in More Detail:
* Subject Distance: The closer the subject is to the beauty dish, the harsher the light will appear, regardless of the size. Larger dishes can be used closer without becoming too harsh, and smaller dishes should ideally be positioned closer for the most impact.
* Light Quality (Hard vs. Soft): "Hard" light is directional and creates strong shadows and highlights. "Soft" light is diffused and wraps around the subject, filling in shadows and creating a more even illumination. Smaller beauty dishes tend towards harder light, while larger ones tend towards softer light.
* Portability: If you're shooting on location, a smaller, lighter beauty dish is essential. Consider folding or collapsible models.
* Studio Space: Larger beauty dishes require more space to maneuver, both for placement and for the photographer.
* The Look You Want: Think about the style of portraits you want to create. Do you want dramatic, edgy portraits with strong shadows, or softer, more flattering images?
* Diffusers and Grids: You can modify the light from a beauty dish using diffusion socks (which soften the light) or grids (which control the spread of the light and reduce spill). These accessories can make a beauty dish more versatile.
Recommendations for Beginners:
* Start with a 20-22" beauty dish. This is a good compromise between size, price, and light quality. It's versatile enough to experiment with different portrait styles.
* Consider a beauty dish with a removable deflector plate. Some dishes allow you to remove the deflector to create a slightly different light quality.
* Don't be afraid to experiment! The best way to find the right beauty dish for you is to try different sizes and see what works best for your style and your subjects.
In summary:
The "best" size beauty dish is subjective and depends on your specific needs and preferences. Consider the factors outlined above to make an informed decision. Start with a 20-22" beauty dish if you're unsure, and then experiment with other sizes to see what gives you the look you're after. Good luck!
