What is an External Flash?

Definition and purpose of an external flash

An external flash, also known as a speedlight or a hot shoe flash, is a supplemental light source that can be attached to a camera’s hot shoe or used off-camera to provide additional lighting in photography. Unlike the built-in flash on most cameras, an external flash offers more power, versatility, and control over the quality of light, allowing photographers to achieve better lighting results.

The primary purpose of an external flash is to provide additional light in situations where the available light is insufficient or unflattering. It can be used in various scenarios, such as indoor and low-light environments, outdoor portraits, studio setups, and even in challenging lighting conditions like high contrast or backlight situations. The use of an external flash can significantly enhance the overall image quality by providing better exposure, reducing shadows, minimizing red-eye, and adding depth and dimension to the subject.

Benefits of using an external flash

Using an external flash has several advantages over relying solely on natural light or the built-in flash of a camera. Here are some key benefits of using an external flash:

  1. Increased Power and Range: External flashes are more powerful than built-in flashes, allowing photographers to illuminate subjects that are further away. The increased power also helps in overcoming harsh lighting conditions and achieving proper exposure.

  2. Ability to Control the Quality of Light: External flashes offer various adjustable settings, such as flash output, zoom, and flash duration, allowing photographers to control the intensity, direction, and color temperature of the light. This control helps in creating a more pleasing and professional-looking image.

  3. Reduced Red-Eye: The positioning of the external flash, whether on-camera or off-camera, helps to minimize the occurrence of red-eye in portraits. By placing the flash away from the camera’s lens axis, the chances of light reflecting off the subject’s eyes and causing red-eye are greatly reduced.

  4. Versatility and Flexibility: External flashes can be used both on-camera and off-camera, offering photographers the flexibility to experiment with different lighting setups and techniques. Off-camera flash, in particular, allows for creative lighting effects, such as side lighting, backlighting, and dramatic shadows.

  5. Better Battery Performance: External flashes have their own power source, usually in the form of AA batteries, which reduces the drain on the camera’s battery. This means that utilizing an external flash will not only provide better lighting but also extend the overall battery life of the camera.

  6. Compatibility with Multiple Camera Models and Brands: External flashes are designed to be compatible with various camera models and brands. This makes them a versatile accessory that can be used across different camera systems, allowing photographers to continue using the same flash even when upgrading their equipment.

Choosing the Right External Flash

When it comes to choosing the right external flash for your photography needs, there are several factors to consider. It’s essential to understand the specifications and features of external flashes to make an informed decision. Let’s explore some key considerations before purchasing an external flash:

Considerations before purchasing an external flash

  1. Flash Power and Guide Numbers: The flash power of an external flash determines its ability to illuminate a subject effectively. The guide number (GN) is a measure of the flash’s power and range. A higher GN indicates a more powerful flash. Consider the type of photography you engage in and choose a flash with sufficient power to meet your requirements.

  2. TTL vs. Manual Flash: External flashes can either be TTL (Through-The-Lens) or manual. TTL flashes automatically adjust the flash output based on the camera’s metering system, while manual flashes require manual adjustment of flash settings. Choose a flash type that suits your shooting style and preference.

  3. Compatibility with Camera Models and Brands: Ensure that the external flash you choose is compatible with your camera model and brand. Different camera manufacturers may have specific flash mounting systems, so it is crucial to select a flash that can be seamlessly integrated with your camera.

  4. Flash Recycling Time: The recycling time of a flash refers to the time it takes for the flash to recharge after firing. A shorter recycling time allows for faster consecutive shots, which is particularly important in fast-paced situations like sports or event photography.

  5. Zoom and Swivel Head: Consider a flash with a zoom and swivel head feature. A zoom head allows you to adjust the flash’s beam angle to match the focal length of your lens, while a swivel head enables you to bounce the flash off ceilings or walls to create softer and more diffuse lighting.

Understanding Flash Power and Guide Numbers

Flash power and guide numbers are essential specifications to consider when choosing an external flash. Flash power refers to the strength of the flash output, while guide numbers provide a reference for the flash’s range and exposure.

Flash Power

Flash power is measured in watts per second (Ws) or joules (J) and represents the total amount of light emitted by the flash. A higher flash power indicates a more powerful flash with greater illumination capabilities. It is essential to choose a flash with sufficient power to compensate for the desired subject distance, lighting conditions, and desired light output.

Guide Numbers

Guide numbers (GN) allow photographers to estimate the flash’s effective range for a given aperture and ISO setting. The guide number is determined by multiplying the flash-to-subject distance with a specific f-number. The formula for calculating the guide number is GN = distance × f-number.

For example, if the flash’s guide number is 40 and the aperture is set to f/4, then the flash can properly expose a subject up to 10 feet away (40 divided by 4). By knowing the guide number, photographers can determine the flash’s range based on their desired aperture and subject distance.

Compatibility with Camera Models and Brands

When purchasing an external flash, it is crucial to ensure compatibility with your camera model and brand. Different cameras have different flash mounting systems, and choosing a flash that is specifically designed for your camera will ensure seamless integration and optimal performance.

Most camera manufacturers produce their own line of external flashes that are designed to work perfectly with their camera systems. These flashes usually offer advanced features and integration options that are not available with third-party flashes. However, third-party flashes from reputable manufacturers also offer excellent compatibility with multiple camera models and brands, making them a cost-effective alternative.

Before making a purchase, check the flash’s compatibility list to ensure that it is explicitly compatible with your camera model and brand. Additionally, it is worth considering future upgrades or changes in camera equipment to ensure the flash’s compatibility remains intact.

Using External Flashes Effectively

Using external flashes effectively requires a good understanding of the various flash modes and settings available. By mastering flash exposure and control, and using bounce flash techniques, photographers can enhance their lighting techniques and achieve better results.

Understanding flash modes and settings

External flashes offer several flash modes and settings that allow photographers to control the light output and effectively illuminate their subjects. Here are some commonly found flash modes and settings and their purpose:

  1. Manual Mode: In manual mode, photographers have full control over the flash power. This mode is ideal for photographers who prefer complete control and want to adjust the flash output manually to achieve the desired exposure.

  2. TTL Mode: TTL mode (Through-The-Lens) utilizes the camera’s metering system to automatically determine the flash power based on the scene and subject. The camera measures the ambient light and adjusts the flash output accordingly, resulting in well-exposed images.

  3. High-Speed Sync (HSS) Mode: High-Speed Sync mode allows photographers to use flash at faster shutter speeds beyond the camera’s normal sync speed. This is useful when shooting with wider apertures or in bright outdoor environments, where the camera’s maximum shutter speed may not synchronize with the flash.

  4. Wireless Mode: Many external flashes offer wireless capabilities, allowing them to be used off-camera. In wireless mode, the flash is triggered remotely, enabling photographers to have greater control over the direction and positioning of the light.

  5. Flash Compensation: Flash compensation allows photographers to adjust the flash output up or down to achieve the desired level of lighting. Positive flash compensation increases the flash output, while negative flash compensation decreases it.

It’s essential to familiarize oneself with the flash’s modes and settings and understand how each one can be applied in different shooting situations. Experimentation and practice will help in mastering the art of using external flashes effectively.

Mastering flash exposure and control

Achieving proper flash exposure requires an understanding of flash exposure settings and their impact on the final image. Here are some key considerations when it comes to flash exposure:

  1. Metering Mode: Most cameras offer various metering modes, such as evaluative, center-weighted, and spot metering. When using flash, it is recommended to set the camera’s metering mode to ‘TTL’ or ‘Evaluative’ to ensure accurate flash exposure.

  2. Flash Power and Distance: The flash’s power and the subject’s distance from the flash affect the flash exposure. Increasing the flash power or bringing the flash closer to the subject will result in a brighter exposure, while decreasing the power or moving the flash away will result in a darker exposure.

  3. Aperture and ISO Settings: The aperture and ISO settings also play a role in flash exposure. A wider aperture lets more light in, resulting in a brighter exposure, while a narrower aperture allows less light, resulting in a darker exposure. Raising the ISO sensitivity can also brighten the image but may introduce more noise.

  4. Flash-to-Subject Distance: The flash-to-subject distance affects the light intensity and exposure. The inverse square law states that the light intensity decreases as the square of the distance increases. Therefore, doubling the distance between the flash and the subject will result in a fourfold reduction in flash intensity.

By understanding these factors and experimenting with different settings, photographers can achieve balanced and well-exposed flash images.

Using bounce flash for better lighting

Bounce flash is a popular technique that involves aiming the flash at a reflective surface such as a ceiling or a wall, redirecting the light to create softer, more diffused lighting. This technique helps to eliminate harsh shadows, reduce the chances of red-eye, and create more flattering lighting for portraits.

When using bounce flash, consider the following tips:

  1. Ceiling Bounce: Pointing the flash toward a white or neutral-colored ceiling allows the light to bounce off and create soft, indirect lighting. This technique is particularly effective when shooting indoors or in small spaces with low ceilings.

  2. Wall Bounce: Bouncing the flash off a nearby wall can produce a similar effect to ceiling bounce but provides more control over the direction and quality of light. Angling the flash towards the wall at different angles can create interesting side lighting or fill light.

  3. Diffusion Panels: Some external flashes come with built-in diffusion panels or attachable diffusers that can be used to further soften the light. These panels help to spread the light more evenly, resulting in even softer shadows and more pleasing light falloff.

  4. Exposure Compensation: When using bounce flash, it may be necessary to adjust the flash exposure compensation to compensate for changes in light intensity due to the reflective surface. Experimenting with exposure compensation and reviewing the resulting images will help in achieving the desired lighting effect.

Using bounce flash effectively requires practice and experimentation to understand the impact of different surfaces and angles on the quality of light. With time, photographers can achieve more natural-looking and professional lighting using this technique.

Techniques for Creative Flash Photography

External flashes open up a world of creative possibilities in photography. Beyond the standard on-camera flash, photographers can explore various techniques to achieve unique lighting effects and add a touch of creativity to their images.

Creating soft and diffused lighting

Soft and diffused lighting can add a touch of elegance and gentleness to a subject. By softening the light, shadows are reduced, and the overall image appears more pleasing. Here are some techniques to create soft and diffused lighting:

  1. Using Softboxes and Umbrellas: Softboxes and umbrellas are popular light modifiers that produce soft, diffused light. They work by spreading the light across a larger area, creating softer shadows and more even lighting. Softboxes can be attached directly to the flash, while umbrellas are positioned in front of the flash to reflect the light.

  2. Using Diffusion Panels: Some external flashes come with built-in diffusion panels or attachable diffusers. These panels help to spread the light more evenly, resulting in softer shadows and a more diffused light source.

  3. Using Reflectors: Reflectors can be used in conjunction with an external flash to bounce and diffuse the light. Silver or white reflectors can bounce the flash’s light onto the subject, resulting in softer lighting.

  4. Deflecting the Flash: Instead of aiming the flash directly at the subject, try deflecting the light by positioning the flash at an angle or using a bounce card. This technique helps to soften the light and reduce the harshness of direct flash.

Experimentation with different lighting modifiers and techniques will allow photographers to achieve the desired level of softness and diffusion in their images.

Using off-camera flash for dramatic effects

Off-camera flash provides photographers with greater control over the direction and quality of lighting, allowing for dramatic and creative effects. By detaching the flash from the camera and positioning it strategically, photographers can achieve unique lighting scenarios. Here are some techniques for using off-camera flash:

  1. Side Lighting: Placing the flash to the side of the subject creates dramatic side lighting, emphasizing textures and adding depth to the image. This technique works well for portraits, highlighting facial features and creating mood.

  2. Backlighting: Positioning the flash behind the subject and pointing it towards the camera creates a striking backlight effect. It creates silhouettes or rim lighting, outlining the subject and separating it from the background.

  3. Fill Lighting: Using off-camera flash as fill light helps to balance the exposure between the subject and the background. By positioning the flash opposite the main light source, photographers can fill in shadows and create a more evenly lit image.

  4. Wireless Flash Setup: Utilize wireless flash triggers and receivers to control multiple off-camera flashes simultaneously. This allows for more complex lighting setups, such as using multiple flashes to create a three-point lighting setup.

Using off-camera flash effectively requires practice and experimentation. It involves understanding the desired effect, the direction of light, and the positioning of the flash to create the desired mood and impact.

Freezing motion with high-speed sync

High-speed sync (HSS) is a flash mode that allows photographers to freeze fast-moving subjects even at high shutter speeds. Standard flash synchronization usually limits the shutter speed to the camera’s maximum sync speed, typically around 1/200 to 1/250 of a second. However, with HSS, photographers can surpass this limit and use faster shutter speeds, up to the camera’s maximum shutter speed.

This technique is particularly useful for freezing motion in situations like sports photography or capturing fast-moving subjects. By using HSS, photographers can effectively eliminate motion blur even in bright outdoor environments. However, it’s important to note that using HSS may reduce the flash’s power output, requiring the flash to be closer to the subject or using additional flashes to compensate for the loss of power.

Understanding Flash Accessories

To enhance the capabilities of external flashes and achieve more creative lighting effects, photographers can utilize various flash accessories. These accessories help shape the light, control color temperatures, and allow for wireless flash triggering. Let’s explore some common flash accessories and their uses:

Diffusers and modifiers for shaping light

Diffusers and modifiers are accessories that alter the quality and direction of light emitted from the flash, allowing for more control over the lighting. Here are some commonly used diffusers and modifiers:

  1. Softboxes: Softboxes are large, lightweight enclosures with a diffusion panel that covers the front opening. They create a soft, even light that helps to reduce harsh shadows and produce more flattering light.

  2. Umbrellas: Umbrellas work similarly to softboxes, spreading the light across a larger surface area. They come in two types—shoot-through and reflective. Shoot-through umbrellas let the flash pass through the fabric, while reflective umbrellas redirect the flash’s light back towards the subject.

  3. Grids: Grids are honeycomb-like attachments that fit over the flash head, narrowing the spread of light and controlling its direction. They create more focused and directional lighting, allowing photographers to highlight specific areas or control light spill.
