What is OCF in Photography?

Updated: Apr 7

what is ocf in photography

Have you ever gotten frustrated trying to shoot in less-than-ideal lighting conditions? Harsh sunlight, deep shadows, dimly lit rooms - it's enough to drive any photographer crazy!

Well, it's time to master off-camera flash (OCF) and take control of your lighting once and for all.

What Is OCF in Photography?

OCF is any flash unit used in photography that is not physically connected to the camera. This gives you much greater flexibility in your lighting and allows you to create better, more controlled illumination since you can move light sources into different positions around your subject.

How Does OCF Work?


So, how does it work? Well, instead of relying on the built-in flash on your camera (which can often create harsh, unflattering light), you place your external flash unit(s) away from the camera, pointing them at your subject from different angles and distances.

This gives you a level of flexibility and control that you just can't get with an on-camera flash. You can sculpt the light, create depth and dimension, and produce portraits with a gorgeous, wrap-around quality that simply can't be achieved with a flash on the camera.

Advantages of OCF over On-Camera Flash

The advantages of OCF over on-camera flash are numerous:

  • Control: You can correct poor illumination or color casts, control both ambient lighting and the light on your subjects, and place the light where a bounced flash cannot, such as behind your subject or in the path of dramatic impact.

  • Creativity: With OCF, you can sculpt light to create stunning shadows, highlights, and textures, transforming ordinary scenes into extraordinary works of art.

  • Versatility: OCF can be used in a wide range of photography genres, from portraits and product shots to event photography and even landscapes.

Equipment Needed for OCF Photography


To get started with OCF, you'll need a few essential pieces of gear:

  • External Flash Unit(s): These portable flashes, also known as speed lights or strobes, are the heart of your OCF setup. You'll need at least one, but using multiple flashes can unlock even more creative possibilities.

  • Light Modifiers: Umbrellas, softboxes, and other modifiers can help shape and control the light from your OCF flashes, creating softer, more flattering illumination.

  • Batteries: Make sure to have plenty of rechargeable Ni-MH (Nickel-Metal Hydride) batteries on hand to power your flash units.

  • Wireless Trigger and Receiver Set: These allow you to trigger your off-camera flashes wirelessly from your camera, giving you the freedom to position the lights wherever you need them.

  • Stands and Mounting Options: You'll need sturdy light stands to position your OCF flashes at different heights and angles, as well as swivel mounts to attach the flashes and modifiers.

For beginners, a good place to start with your external flash is by practicing bouncing it and using TTL (Through The Lens) mode. TTL allows the camera and flash to work together to calculate the correct amount of flash for a given exposure, making it easier to get well-lit shots as you're learning.

OCF Lighting Techniques and Setups

With OCF, you have a world of possibilities when it comes to lighting setups and techniques. Here are a few of the basics:

  • Key light: This is the main light source, illuminating your subject and creating the dominant shadows and highlights.

  • Fill light: A secondary light source is used to "fill in" and soften the shadows created by the key light, reducing contrast for a more flattering look.

  • Rim light: A light placed behind your subject, creating a glowing outline or "rim" that separates them from the background and adds a sense of depth.

Common OCF lighting setups include:

  • One-light setup: A single key light, often used with a softbox or umbrella modifier to create a soft, flattering look.

  • Two-light setup: A key light and a fill light, allowing you to control the contrast and shadows on your subject.

  • Three-light setup: A key light, fill light, and rim light, giving you maximum control over the lighting and creating a dramatic, dimensional look.

There are countless variations on these basic setups, and the possibilities are limited only by your creativity. But don't worry – there are plenty of online tutorials and diagrams to help guide you as you experiment with different lighting styles.

Using OCF for Different Photography Genres


One of the great things about OCF is that it can be applied to a wide variety of photography genres. Here are just a few examples:


OCF is a favorite technique for portrait photographers, allowing them to create beautiful, flattering light on their subjects. From headshots to environmental portraits to group shots, OCF gives you control over the lighting that just isn't possible with natural light alone.

Product Photography

With OCF, you can light small objects and products in a controlled environment, eliminating unwanted shadows and highlights and creating a clean, professional look.

Event Photography

OCF is a lifesaver for event photographers, who often have to deal with challenging lighting conditions like low-light venues or mixed lighting sources. A few well-placed flashes can make all the difference in capturing stunning images of the special moments.

Landscape Photography

While not the first thing that comes to mind, OCF can also be used in landscape photography. A remote flash can provide a subtle fill light to open up shadows in a scene, or it can be used for light painting techniques to add drama and interest to your outdoor shots.

Tips and Tricks for Mastering OCF Photography

While OCF offers incredible creative potential, mastering it takes practice and the right techniques. Here are some tips and tricks to help you take your OCF photography to the next level:

  • Use a Light Meter: Invest in a good light meter to help you accurately measure the light output from your OCF setup. This will allow you to achieve consistent exposures and avoid guesswork.

  • Experiment with Feathering: Feathering is the technique of positioning your OCF light at an angle to your subject, creating a gradual transition from highlight to shadow. Experiment with different angles to achieve a variety of lighting effects.

  • Try Gels and Filters: Gels and filters can help you modify the color and quality of your OCF light. Use warm gels to mimic natural sunlight, cool gels to create a crisp, modern look, or colored gels to add creative flair to your images.

  • Mix Ambient and OCF Light: Don't be afraid to mix ambient light with your OCF setup. Balancing the two can create a natural, harmonious look that complements your subject and the environment.

  • Use Reflectors and Flags: Reflectors can bounce light back onto your subject, filling in shadows and adding highlights. Flags, on the other hand, can help block unwanted light and create dramatic shadows.

  • Try Different Light Modifiers: Modifiers like softboxes, umbrellas, beauty dishes, and grids can dramatically change the quality and direction of your OCF light. Experiment with different modifiers to see how they affect the mood and feel of your images.

Remember, practice makes perfect. The more you experiment with OCF, the more comfortable and creative you'll become with this powerful lighting technique.


Phew, that was a lot of information! But I hope you now have a solid understanding of what OCF in photography is and how it can take your images to the next level.

To recap:

  • OCF (Off-Camera Flash) is a technique where photographers use external flash units positioned away from the camera to control the direction and quality of light.

  • It offers many advantages over on-camera flash, including better control over ambient and subject lighting, the ability to correct poor illumination, and the flexibility to place light sources where on-camera flash can't reach.

  • To get started with OCF, you'll need a few key pieces of gear like an external flash, wireless triggers, light stands, and modifiers.

  • OCF can be used to create a wide variety of lighting setups and effects, from simple one-light portraits to more complex multi-light setups for drama and dimension.

  • It's a versatile technique that can be applied to many different photography genres, from portraits and products to events and even landscapes.

  • As you dive into OCF, remember to practice balancing ambient and artificial light, experiment with modifiers, troubleshoot issues as they arise, and always prioritize safety.

So what are you waiting for? Grab your gear, set up some lights, and start exploring the amazing world of OCF photography!

With a little practice and creativity, you'll be creating stunning, expertly-lit images in no time. Happy shooting!
