What To Know
- A shallow depth of field means only a small area is in focus, while the background is beautifully blurred.
- Conversely, a narrower aperture (larger f-number like f/16 or f/22) lets in less light and creates a deeper depth of field, keeping more of the background in focus.
- On your Canon EOS M50, you can adjust the aperture using the aperture ring on your lens (if your lens has one) or by using the aperture control dial on the camera body.
The Canon EOS M50 is a fantastic camera for capturing stunning photos, but sometimes you want to add that extra touch of professionalism by blurring the background, making your subject pop. This technique, often called “bokeh,” is a popular choice for portraits, product photography, and even macro shots. But how do you achieve that smooth, dreamy blur on your Canon EOS M50? This guide will walk you through the steps, explaining the concepts and techniques to help you master the art of background blur.
Understanding Depth of Field
Before diving into the specifics of the Canon EOS M50, let’s understand the fundamental concept behind background blur: depth of field (DOF). Depth of field refers to the range of distances in your scene that appear acceptably sharp. A shallow depth of field means only a small area is in focus, while the background is beautifully blurred. A deep depth of field, on the other hand, keeps everything in focus, from foreground to background.
Key Factors Influencing Background Blur
Several factors determine the amount of background blur you achieve:
- Aperture: The aperture is the opening in your lens that controls the amount of light entering the camera. A wider aperture (smaller f-number like f/1.8 or f/2.8) lets in more light and creates a shallower depth of field, resulting in more pronounced blur. Conversely, a narrower aperture (larger f-number like f/16 or f/22) lets in less light and creates a deeper depth of field, keeping more of the background in focus.
- Focal Length: The focal length of your lens determines the field of view. Longer focal lengths (like 50mm or 100mm) generally produce a shallower depth of field than shorter focal lengths (like 18mm or 24mm).
- Distance to Subject: The closer you are to your subject, the shallower the depth of field becomes, leading to more background blur. Conversely, moving further away from your subject increases the depth of field, making the background sharper.
- Sensor Size: Larger sensors, like those found in DSLRs, generally produce a shallower depth of field compared to smaller sensors like those in mirrorless cameras. However, the Canon EOS M50’s APS-C sensor size still allows for impressive background blur.
How to Blur Background on Canon EOS M50: A Step-by-Step Guide
Now, let’s put these concepts into practice with your Canon EOS M50. Here’s a step-by-step guide:
1. Choose the Right Lens: Start by selecting a lens with a wider aperture (smaller f-number). While the Canon EOS M50’s kit lens (15-45mm f/3.5-6.3) is versatile, it might not provide the most dramatic blur. Consider investing in a prime lens like the Canon EF-M 22mm f/2 STM or Canon EF-M 32mm f/1.4 STM for more pronounced bokeh.
2. Adjust Your Aperture: The key to achieving background blur is using a wide aperture. On your Canon EOS M50, you can adjust the aperture using the aperture ring on your lens (if your lens has one) or by using the aperture control dial on the camera body. Start with an aperture of f/2.8 or wider for a significant blur effect.
3. Get Close to Your Subject: The closer you are to your subject, the more pronounced the background blur will be. Experiment with different distances to find the ideal balance for your composition.
4. Use a Longer Focal Length: A longer focal length, like 50mm or 100mm, will create a shallower depth of field than a shorter focal length. If you have a zoom lens, try zooming in for a more blurred background.
5. Control the Background: The background plays a crucial role in creating a visually appealing bokeh effect. Choose a background that complements your subject and avoids distracting elements. Try using a plain background or one with soft, diffused colors for the best results.
6. Experiment with Focus Modes: The Canon EOS M50 offers various focus modes, including single-point autofocus, zone autofocus, and continuous autofocus. Experiment with different modes to find the best one for your subject and shooting conditions.
7. Utilize Manual Focus for Precision: If you want ultimate control over the area in focus, consider using manual focus. This allows you to precisely adjust the focus point and achieve a desired level of background blur.
8. Consider the Lighting: Good lighting is essential for achieving beautiful bokeh. Avoid harsh direct sunlight, which can create harsh shadows and reduce the overall quality of the blur. Soft, diffused lighting, like that found on an overcast day or in the shade, is ideal for creating a smooth, dreamy background blur.
Going Beyond the Basics: Creative Bokeh Techniques
Once you’ve mastered the fundamentals of background blur, you can explore creative techniques to enhance your photography:
- Bokeh Balls: Bokeh balls are the circular highlights created by out-of-focus lights. They can add a whimsical and artistic touch to your photos. Try shooting with a wide aperture and using a point light source in the background to create these stunning bokeh effects.
- Using Bokeh for Storytelling: Bokeh can be used to create a sense of depth and isolate your subject from the surroundings, drawing the viewer’s attention to the main point of interest. You can also use it to subtly hint at the context or environment without overwhelming the image.
- Experiment with Lens Filters: There are various lens filters designed to enhance bokeh effects. For example, a soft focus filter can create a gentle, dreamy blur, while a star filter can add star-shaped highlights to your out-of-focus areas.
Final Thoughts: Mastering the Art of Background Blur
Mastering the art of background blur on your Canon EOS M50 is a journey of exploration and experimentation. By understanding the key factors influencing depth of field and applying the techniques outlined in this guide, you can create stunning photos with a professional touch. Remember, practice makes perfect, so don’t be afraid to experiment, try different settings, and find your own unique style.
Basics You Wanted To Know
Q: Can I blur the background using the Canon EOS M50’s built-in features?
A: The Canon EOS M50 offers a “Background Blur” setting in its creative assist mode, which automatically adjusts the aperture and other settings to achieve a blurred background. However, for more precise control and creative flexibility, it’s recommended to manually adjust the aperture and other settings.
Q: Does using a wide aperture always result in a better background blur?
A: While a wider aperture generally creates a shallower depth of field, other factors, like the distance to your subject and the focal length, also play a role. Experiment with different settings to find the ideal balance for your desired level of blur.
Q: How can I achieve a smooth and pleasing bokeh effect?
A: Using a lens with a rounded aperture diaphragm, choosing a smooth background, and avoiding harsh lighting can help create a smooth and pleasing bokeh effect. Experiment with different backgrounds and lighting conditions to find what works best for you.
Q: What are some common mistakes to avoid when trying to blur the background?
A: Common mistakes include using too narrow an aperture, not getting close enough to your subject, and choosing a distracting background. Pay attention to these factors to avoid compromising your bokeh effect.
Q: Can I create background blur using post-processing?
A: While you can use software like Adobe Photoshop or Lightroom to create a blurred background effect, it’s often best to achieve the blur in-camera for the most natural and realistic results. Post-processing can be used to enhance the blur, but it’s not a substitute for proper camera techniques.
