Struggling with grainy, blurry footage when shooting in dim conditions? Low light settings can make all the difference for businesses aiming to capture high-quality visuals even in challenging environments.
As a photographer with years of experience, I’ve handled various lighting challenges and know what works best. These insights can help optimize settings for better results, especially in low light environments.
Here are 2 key strategies to start:
- Use a Wide Aperture (Low f-stop)
- Lower the Shutter Speed
In this guide, you’ll learn practical, easy-to-apply settings that will help you capture more detail and minimize noise when shooting in low light conditions.
Let’s get started!
1. Quick Overview
Capturing clear images in low light can be challenging, but a few simple adjustments can make a big difference. These settings help brighten photos and reduce blur, even in dim or tricky lighting conditions. Below, we’ll take a quick look at the key settings that work best for low light. Then, we’ll explore how each setting can be fine-tuned to enhance image quality further.
| Setting | Recommended Value | How It Helps in Low Light |
| Aperture | F/2.8 or Wider | A wide aperture lets in more light, which is crucial for brightening the scene. It also creates a shallow depth of field, making subjects stand out against a blurred background. |
| ISO Sensitivity | 1000 – 3200 | Increasing the ISO amplifies light sensitivity, allowing for clearer images in dark settings. However, use moderately to avoid introducing too much noise. |
| Shutter Speed | 1″ – 1/60 | Slowing down the shutter speed captures more light over a longer period, resulting in brighter images. A tripod is recommended to prevent motion blur at slower speeds. |
| File Type | RAW | Shooting in RAW preserves all the image data, making it easier to adjust exposure, shadows, and colors during post-processing without losing quality. |
| White Balance | Match Lighting Source (e.g., Tungsten, Daylight) | Adjusting white balance helps correct color casts from artificial lighting, ensuring accurate colors in low-light photos. |
| Frame Rate (Video) | 24 – 30 fps | Lowering the frame rate allows each frame to gather more light, resulting in brighter video footage in dim environments. |
| Image Stabilization | Enable (if available) | Helps reduce blur caused by slight movements when shooting handheld, especially with slower shutter speeds. |
| Focus Mode | Manual Focus | Autofocus can struggle in low light, so using manual focus provides more control and precision, especially for stationary subjects. |
| Exposure Compensation | +0.3 to +2.0 | Adjusting exposure compensation brightens the overall image when automatic settings result in underexposure. Useful for scenes where additional light is needed. |
| Flash with Diffuser | Use When Necessary | A flash with a diffuser softens the light, reducing harsh shadows and providing a more natural look. Useful in extremely dark environments where other adjustments aren’t sufficient. |
2. Use a Wide Aperture (Low f-stop)
Using a wide aperture, like f/1.8 or f/2.0, lets in more light, which is essential for capturing clear images in dark settings. This helps achieve brighter photos without needing to increase ISO too much, which can introduce noise. Here’s how to use this setting effectively:
- Select the Lowest f-stop Available: Choosing a lower f-stop widens the lens opening, allowing more light to hit the sensor. This is especially useful in dimly lit environments where every bit of light counts.
- Create a Shallow Depth of Field: A wide aperture results in a blurred background, which can help draw attention to the main subject. This is great for portraits or product shots where focus is key.
- Combine with a Low ISO: While a wide aperture lets in more light, it’s best to keep the ISO as low as possible to avoid graininess. This creates a cleaner, sharper image.
- Use with Prime Lenses: Prime lenses often have lower f-stop capabilities than zoom lenses. This makes them ideal for low-light photography, as they gather more light with better clarity.
3. Lower the Shutter Speed
Lowering the shutter speed allows more light to reach the sensor, which is crucial in low-light settings where brightness is limited. This helps capture well-exposed images without relying heavily on increasing ISO. Here’s how to make the most of this setting:
- Stabilize the Camera with a Tripod: A slower shutter speed increases the risk of blur from even small movements. Using a tripod helps keep the camera stable, resulting in sharper photos, especially in dark environments.
- Start with a Moderate Shutter Speed: In low light, try starting with a shutter speed around 1/30th of a second. This setting allows for better light capture while still minimizing motion blur for stationary subjects.
- Use for Capturing Ambient Light: Lower shutter speeds can make the most of ambient light sources, like streetlights or soft indoor lighting, giving the photos a natural glow. This is especially useful when a flash is not desirable.
- Adjust Other Settings for Balance: Pair a lower shutter speed with a wide aperture and moderate ISO to enhance light intake. This combination helps achieve bright and clear images without too much noise or blur.
4. Increase ISO Sensitivity
Increasing ISO sensitivity boosts the camera’s ability to capture light, brightening photos in dim environments. It’s especially useful when aperture and shutter speed adjustments aren’t enough. Here’s how to adjust ISO effectively:
- Start with Moderate ISO Levels: Begin at ISO 400 or 800 to let in more light without adding too much graininess. Only raise it if absolutely necessary to avoid noise.
- Higher ISO for Action Shots: For fast-moving subjects, using ISO 1600 or 3200 helps keep a faster shutter speed to reduce blur.
- Watch Out for Noise: While increasing ISO can brighten images, it may also introduce grain. Aim to use the lowest ISO that still results in a clear photo.
- Adjust ISO Last: Only increase ISO after optimizing aperture and shutter speed. This approach helps maintain image quality while achieving the desired brightness.
5. Enable Image Stabilization (If Available)
Image stabilization is a helpful feature that reduces the impact of slight camera movements, especially when using slower shutter speeds in low light. This feature can be found in many lenses and camera bodies, making it easier to capture sharper images without needing a tripod. Here’s how to make the most of this feature:
- Check for Built-in Stabilization: Some lenses or cameras include this feature, reducing blur when shooting handhelds in low light. For instance, many modern mirrorless cameras have in-body stabilization that works well for capturing clear images in dim settings.
- Use Stabilization for Handheld Shots: When a tripod isn’t available, stabilization is great for keeping handheld photos sharp, especially in darker environments.
- Turn Off Stabilization on a Tripod: When using a tripod, turn off stabilization since it can cause tiny movements that blur the shot.
- Pair with Other Settings: Stabilization works best with a wide aperture and moderate ISO for clearer, well-exposed photos in low light.

6. Shoot in RAW Format
Shooting in RAW format captures all the details without compressing the image, which allows more flexibility during editing. This is especially useful in low-light situations where adjusting shadows and colors can be challenging. Here’s how to make the most of RAW:
- Capture Maximum Image Data: RAW files save all the data from the sensor, unlike JPEGs that compress and lose some details. This means more flexibility to adjust brightness and contrast while keeping image quality intact.
- Fix Issues in Post-Processing: Low-light photos often need adjustments like brightening shadows or reducing noise. With RAW, these changes are easier to make without reducing the overall quality.
- Preserve Original Quality: Since RAW files are uncompressed, they keep the highest level of detail. This is critical for projects where details are important, especially in fields like security or medical imaging.
- Consider Storage Space: RAW files are larger than JPEGs, so prepare enough storage. The extra space is worth it for the enhanced editing capabilities.
7. Use Exposure Compensation
Exposure compensation adjusts the camera’s exposure levels to make images brighter or darker without changing the main settings like aperture or shutter speed. This is helpful when automatic settings result in too-dark photos in low light. Here’s how to use it:
- Adjust for Low-Light Scenes: In dim conditions, the camera’s auto settings might underexpose the scene. Adding positive exposure compensation (like +1 or +2) can brighten the photo to the desired level.
- Make Small Adjustments: Use small steps like +0.3 or +0.7 to avoid overexposure. This allows more control over how light or dark the final image turns out.
- Combine with Manual Settings: Use exposure compensation along with manual adjustments for even better control. This helps fine-tune the brightness while optimizing other settings.
- Reset After Use: Always reset the exposure compensation afterward. Leaving it on can affect the exposure in future photos, leading to unexpected results.
8. Switch to Manual Focus
Manual focus is useful in low light where autofocus might struggle to find a clear subject. It gives more control, allowing for precise focus even in challenging lighting conditions. Here’s how to get the best results:
- Use Focus Peaking (If Available): Some cameras highlight in-focus areas on the screen. This makes it easier to adjust focus manually, especially in dim environments.
- Best for Still Subjects: Manual focus is great for non-moving subjects like products or interiors. It avoids the autofocus hunting issue that often happens in low light.
- Zoom In for Fine-Tuning: Many cameras have a live view zoom feature to check focus accuracy. For example, when photographing a product, zooming in can confirm that details like text or textures are perfectly sharp before capturing the shot.
- Pair with a Wide Aperture: Using a wide aperture alongside manual focus helps achieve clearer, sharper images. This combination can be particularly effective when shooting in dark settings.

9. Reduce Frame Rate for Video
Lowering the frame rate when recording in low light allows the camera sensor more time to gather light, resulting in brighter footage. This technique is especially useful for capturing clear video in darker environments. Here’s how to make the most of it:
- Use a Lower Frame Rate: Reducing the frame rate to 24 or 30 frames per second (fps) allows more light to be captured in each frame, making the video appear brighter.
- Great for Stationary Subjects: A lower frame rate works best when recording non-moving subjects or scenes with minimal motion. This helps achieve better exposure without introducing motion blur.
- Balance with Shutter Speed: Pair a reduced frame rate with a slower shutter speed to enhance light intake. This combination can improve overall brightness in low-light video.
- Consider the Impact on Motion: Be aware that lowering the frame rate may result in choppier footage if the scene has fast movement. Use this setting selectively depending on the subject.
10. Adjust White Balance for Accurate Color
Adjusting white balance in low light helps achieve natural colors and prevents odd color casts. This is especially useful when dealing with mixed lighting sources. Here’s how to fine-tune white balance for the best results:
- Match the Lighting Source: Set the white balance according to the type of lighting in the environment, such as tungsten, fluorescent, or daylight. This helps maintain accurate color representation.
- Use Custom White Balance: For better control, use the custom white balance feature. This allows setting a specific point in the scene as a reference to ensure more accurate colors.
- Avoid Relying on Auto White Balance: In low light, automatic white balance may not always get it right, leading to odd color tints. Manual adjustment is usually more reliable.
- Make Adjustments in Post-Processing: If shooting in RAW, white balance can be easily adjusted during editing without losing image quality. This flexibility is helpful when working in unpredictable lighting.
11. Consider Using a Flash with Diffusion
Using a flash in low light can be helpful, but it often results in harsh lighting. Adding a diffuser softens the flash, producing more natural-looking photos. Here’s how to use a flash effectively:
- Use a Diffuser for Soft Lighting: Attach a diffuser to the flash to spread the light more evenly. This reduces harsh shadows and creates a softer, more flattering effect on the subject.
- Adjust Flash Power: Lower the flash intensity to avoid overexposing the scene. Adjusting the flash output can help maintain a balanced exposure.
- Bounce the Flash Off a Surface: When possible, bounce the flash off walls or ceilings to spread the light indirectly. This technique softens the effect further and creates a more natural look.
- Use Flash as a Last Resort: If possible, try increasing ISO or adjusting the aperture before resorting to a flash. This keeps the scene looking more authentic while still capturing enough light.
