What To Know
- High Speed Sync (HSS) is a flash technique that allows you to use a flash with a shutter speed faster than the flash’s maximum sync speed.
- Combine a slow shutter speed with a flash to create a sense of motion blur and ambient light.
- Mastering high speed sync on your Canon 5D Mark IV unlocks a new level of creative control and opens up a world of photographic possibilities.
The Canon 5D Mark IV is a powerhouse camera, renowned for its image quality and versatility. But did you know that it can also handle high-speed flash photography, allowing you to freeze action even in broad daylight? This guide will walk you through the steps on how to set high speed sync on Canon 5D Mark IV.
What is High Speed Sync (HSS)?
High Speed Sync (HSS) is a flash technique that allows you to use a flash with a shutter speed faster than the flash’s maximum sync speed. This is especially useful in bright daylight conditions where you need to use a small aperture to achieve a shallow depth of field. Without HSS, you would be limited to the sync speed of your flash, typically around 1/200th of a second. This would mean that your images would be overexposed in daylight, as the shutter wouldn’t be able to block out enough light.
Why Use HSS?
HSS offers several benefits for photographers:
- Freeze Action: Capture fast-moving subjects, like sports or wildlife, with sharp detail.
- Control Depth of Field: Use smaller apertures to create beautiful bokeh and isolate your subject.
- Shoot in Bright Light: Overcome the limitations of traditional flash sync speeds and shoot in sunny conditions.
- Creative Lighting Options: Experiment with different lighting scenarios and achieve unique effects.
Setting Up Your Canon 5D Mark IV for HSS
To set up your Canon 5D Mark IV for HSS, you’ll need a compatible flash unit. Most modern Canon Speedlites, like the 600EX-RT II, support HSS. Here’s how to get started:
1. Connect Your Flash: Attach your compatible Speedlite to the camera’s hot shoe.
2. Enable HSS on Your Flash: Locate the HSS mode button on your flash (usually marked with an “S” or “HSS” symbol) and press it to activate HSS mode.
3. Set Your Camera’s Shutter Speed: Choose a shutter speed faster than your flash’s maximum sync speed. The maximum HSS shutter speed will vary depending on your flash unit.
4. Adjust Your Aperture: Use a smaller aperture (higher f-stop) to control the amount of light entering the camera.
Understanding the HSS Limitation
It’s important to be aware of the limitations of HSS:
- Flash Power: HSS reduces the power output of your flash, so you may need to compensate by increasing the ISO or using a slower shutter speed.
- Recycle Time: Flash recycle time can be longer in HSS mode, especially with weaker flash power.
- Light Quality: The light from your flash will be softer and less directional in HSS mode.
Tips for Successful HSS Photography
Here are some tips to help you get the most out of high speed sync photography:
- Experiment with Shutter Speeds: Start with a fast shutter speed and gradually decrease it until you achieve the desired balance between freezing motion and ambient light.
- Use a Diffuser: Softbox or umbrella diffusers can soften the flash light and make it more flattering.
- Bracket Your Exposures: Take multiple shots with different shutter speeds and flash power settings to ensure you get the perfect exposure.
- Utilize Flash Compensation: Adjust the flash compensation to fine-tune the flash output and achieve the desired balance between flash and ambient light.
- Focus on the Subject: Use autofocus to ensure your subject is sharp and in focus, especially when shooting moving subjects.
Beyond the Basics: Exploring HSS Techniques
HSS opens up a world of creative possibilities. Here are some advanced techniques to explore:
- Rear Curtain Sync: Trigger the flash at the end of the shutter’s exposure, creating a dramatic streak of light behind your subject.
- Slow Sync: Combine a slow shutter speed with a flash to create a sense of motion blur and ambient light.
- Off-Camera Flash: Use an external flash unit and a trigger to create more dynamic lighting effects.
Wrap-Up: Unleashing the Power of HSS
Mastering high speed sync on your Canon 5D Mark IV unlocks a new level of creative control and opens up a world of photographic possibilities. By understanding the basics, experimenting with techniques, and embracing the limitations, you can use HSS to capture stunning images in any lighting condition.
Quick Answers to Your FAQs
Q: What is the maximum shutter speed I can use with HSS?
A: The maximum HSS shutter speed depends on your flash unit. Consult your flash manual for specific details.
Q: Can I use HSS with all flash units?
A: No, only compatible flash units with HSS capability can be used with this mode. Check the specifications of your flash unit.
Q: How do I know if my flash is in HSS mode?
A: Most flashes have an indicator light or a mode button that shows when HSS is activated.
Q: What are the best settings for HSS photography?
A: The best settings will vary depending on the specific situation. Experiment with different shutter speeds, apertures, and flash power to find the ideal balance for your scene.
Q: Is HSS always necessary?
A: HSS is not always necessary. If you’re shooting in low light or with a slow shutter speed, you can use traditional flash sync without the limitations of HSS.
