How to Fix Overexposed Footage in DaVinci Resolve (S-Log3 Guide)

Overexposed footage is one of the most common problems video editors face. You get back from a shoot, excited to start editing, and then you see it: the sky is blown out, faces are too bright, and all the detail in the highlights is gone. If you were shooting in S-Log3, the problem can be even more frustrating because the flat profile looks washed out to begin with, and it is hard to tell what is actually recoverable.

The good news is that DaVinci Resolve has some of the most powerful tools in the industry for fixing overexposed footage. With a few simple techniques, you can bring back detail, restore contrast, and make your S-Log3 clips look normal again. In this guide, I will walk you through the entire process step by step. No complicated jargon. Just practical advice you can use right away.

Why S-Log3 Footage Gets Overexposed

Before we jump into the fixes, it helps to understand why S-Log3 is so prone to overexposure.

S-Log3 is a log gamma curve developed by Sony. It is designed to capture as much dynamic range as possible. Instead of recording a normal-looking image with strong contrast, it records a flat, low-contrast image that preserves details in both the shadows and the highlights. The idea is that you will add contrast back in post-production.

The problem is that S-Log3 is very sensitive to exposure. If you expose for the shadows, the highlights can blow out. If you expose for the highlights, the shadows can become noisy. Many shooters, especially those new to log profiles, end up overexposing because they are used to exposing for a normal picture profile.

Another issue is that S-Log3 is often paired with high ISO settings. Sony cameras have a dual native ISO, and if you are not careful, you can end up with a lot of noise in the shadows when you try to bring down the exposure in post.

The key takeaway is this: overexposed S-Log3 footage is common, but it is also often recoverable. You just need to know which tools to use and in what order.

Step 1: Assess the Damage

The first thing you should do is figure out how bad the overexposure really is. Not all overexposed footage can be saved. If the highlights are completely clipped—meaning the sensor recorded pure white with no detail—then there is no magic button that will bring that detail back. You can only work with what was actually captured.

Open your clip in DaVinci Resolve and go to the Color page. Look at the scopes. The waveform scope is your best friend here. If you see a flat line at the very top of the waveform, that means the highlights are clipped. If you see peaks that go up but do not flatten out, you still have some detail to work with.

You should also check the RGB parade. This shows you the red, green, and blue channels separately. If one channel is clipped but the others are not, you might have a color cast in the highlights that you can fix. If all three are clipped, you are in trouble.

Another useful tool is the highlight recovery slider in the Camera Raw tab. If you are working with RAW footage, this can sometimes bring back detail that looks lost. But for S-Log3, which is usually recorded as a compressed format like XAVC, you will not have as much flexibility.

Once you have assessed the damage, you can decide on your approach. If the highlights are only slightly overexposed, a few simple adjustments will do the trick. If they are severely blown out, you may need to get creative with secondary corrections or even consider reshooting.

Step 2: Start with Primary Corrections

The first pass of any color correction should be primary corrections. These affect the entire image. Your goal here is to bring the overall exposure down and restore a normal contrast ratio.

In DaVinci Resolve, go to the Color page and select your clip. Open the Primary Wheels panel. You will see four wheels: Lift, Gamma, Gain, and Offset. For overexposed footage, the Gain wheel is your primary tool. Drag the Gain wheel down to reduce the overall brightness. Be careful not to go too far, or you will crush the shadows.

You can also use the contrast slider. Increasing contrast will make the bright areas brighter and the dark areas darker. But if your highlights are already too bright, you might want to reduce the contrast slightly before bringing the exposure down. This can help prevent further clipping.

The Offset wheel is another useful tool. It moves the entire image up or down in brightness without affecting the contrast. If your whole image is too bright, a small adjustment to Offset can help.

As you make these adjustments, keep an eye on the waveform scope. You want the highlights to sit just below the top line, not touching it. You also want the shadows to have some detail. If the waveform looks like a flat line at the bottom, you have crushed the blacks too much.

One important tip: do not try to fix everything with the primary wheels. They are a blunt instrument. They affect the whole image, and if you push them too far, you will introduce noise and artifacts. Use them to get in the ballpark, then move on to more precise tools.

Step 3: Use Curves for Precise Highlight Recovery

Once you have done your primary corrections, the next step is to use curves. The Curves panel in DaVinci Resolve gives you much more control over specific tonal ranges.

There are several curve types available. The most useful for overexposed footage is the Hue vs. Luma curve, but for straight exposure fixes, you want the Custom curve. This is a standard tone curve that lets you adjust the brightness of different parts of the image.

Open the Curves panel and select the Custom curve. You will see a diagonal line from bottom-left to top-right. The bottom-left represents the shadows, and the top-right represents the highlights. To bring down overexposed highlights, click on the top-right part of the line and drag it down. This will reduce the brightness of the highlights without affecting the shadows as much.

You can also add control points. If you want to bring down the highlights but keep the midtones the same, add a point in the middle of the curve and then drag the top-right point down. This creates a more targeted adjustment.

The key with curves is to be subtle. Small adjustments go a long way. If you drag the curve too far, you will create an unnatural look with weird color shifts. Always check your scopes as you work.

Another curve you should try is the Luma curve. This is similar to the Custom curve but it only affects luminance, not color. Sometimes this can give you a cleaner result because it does not introduce color shifts.

If you are working with S-Log3, you might also want to try the Log wheels. These are designed specifically for log footage. They let you adjust the exposure in a way that respects the log curve. You can find them in the Primary Wheels panel by clicking on the Log tab.

Step 4: Apply a Corrective LUT

A LUT, or Look-Up Table, is a preset that transforms the colors and contrast of your footage. For S-Log3, there are specific LUTs designed to convert the flat log image into a normal Rec.709 image.

Applying a corrective LUT can be a huge time-saver. It gives you a good starting point and often fixes the overexposure automatically because the LUT is designed to bring the highlights down to normal levels.

In DaVinci Resolve, you can apply a LUT in the Color page. Right-click on your clip in the timeline or in the Color page node graph and select LUT > Sony > S-Log3 to Rec.709. There are several variations, so you may need to try a few to see which one looks best.

If you do not have the official Sony LUTs, you can download them from Sony's website. They are free. There are also third-party LUTs available, but be careful: some of them are designed for creative looks, not corrective ones. For fixing overexposure, you want a technical LUT that is designed to normalize the footage.

Once you apply the LUT, you may still need to make some adjustments. The LUT is a starting point, not a final answer. Use the primary wheels and curves to fine-tune the exposure and contrast.

One important note: LUTs can sometimes introduce noise or artifacts, especially in the shadows. If you notice this, try applying the LUT before your primary corrections, or use a node-based workflow to apply the LUT in a separate node.

Step 5: Use the HDR Palette

If you are using DaVinci Resolve 17 or later, you have access to the HDR palette. This is a powerful set of tools designed for high dynamic range footage, but it works great for S-Log3 as well.

The HDR palette lets you adjust specific tonal ranges without affecting others. You can adjust the highlights, midtones, and shadows independently. This is perfect for overexposed footage because you can bring down the highlights without darkening the midtones or shadows.

To use the HDR palette, go to the Color page and click on the HDR tab. You will see a series of color wheels and sliders. The most useful for overexposure is the Global wheel, which adjusts the overall exposure. But the real power comes from the zone adjustments. You can select the highlight zone and bring it down, while leaving the midtones and shadows alone.

The HDR palette also has a highlight recovery slider. This is similar to the highlight recovery in the Camera Raw tab, but it works on any footage, not just RAW. It can help bring back detail in blown-out areas.

If you are new to the HDR palette, it can be a bit overwhelming at first. Start with the Global wheel and the zone sliders. Make small adjustments and check your scopes. You will quickly get the hang of it.

Step 6: Reduce Noise and Sharpen

After you bring down the exposure, you may notice that the image looks noisy. This is especially common with S-Log3 footage because the shadows often contain a lot of noise. When you brighten or darken the image, that noise becomes more visible.

DaVinci Resolve has excellent noise reduction tools. Go to the Color page and open the Noise Reduction panel. There are two types: Temporal NR and Spatial NR. Temporal NR works across multiple frames and is great for reducing noise in motion. Spatial NR works on a single frame and is better for static shots.

For overexposed footage, you will likely need to use both. Start with Temporal NR and set the frames to 2 or 3. Then adjust the luma and chroma sliders. Be careful not to overdo it, or you will get a smeared, plastic look. A little noise is better than a lot of smearing.

After noise reduction, you may want to add a slight sharpening. This can help bring back some of the detail that was lost in the overexposure. Use the Sharpen panel and keep the settings subtle. Too much sharpening will create halos around edges.

Step 7: Use Secondary Corrections for Specific Areas

Sometimes the overexposure is not uniform across the entire image. Maybe the sky is blown out but the foreground is fine. Or maybe a face is too bright while the rest of the scene is properly exposed.

In these cases, you need secondary corrections. These are adjustments that affect only a specific part of the image. DaVinci Resolve gives you several tools for this, including qualifiers, power windows, and masks.

The qualifier lets you select a specific color or range of colors. For example, you can select the bright blue of the sky and bring down its exposure without affecting the rest of the image. This is great for fixing blown-out skies.

Power windows let you draw a shape around a specific area. You can then adjust the exposure inside that shape. This is useful for faces or other important subjects.

You can also combine qualifiers and power windows for even more control. For example, you can draw a window around the sky and then use a qualifier to select only the brightest parts of the sky. This gives you very precise control.

Secondary corrections are where DaVinci Resolve really shines. With a little practice, you can fix almost any overexposure problem, as long as the detail is still there.

Step 8: Check Your Work on Different Displays

Once you have finished your corrections, it is important to check your work on different displays. What looks good on your editing monitor might look different on a phone, a TV, or a projector.

Use the scopes to make sure your levels are within broadcast safe limits. The waveform should not be clipping at the top or bottom. The vectorscope should show colors that are within the legal range.

If you are delivering for the web, you have a bit more flexibility, but it is still a good idea to keep your highlights under control. Most streaming platforms will compress your video, and if the highlights are too bright, they can look harsh and unpleasant.

Common Mistakes to Avoid

Before we wrap up, let us talk about some common mistakes people make when fixing overexposed footage.

Mistake 1: Trying to fix everything with one tool. No single tool can fix every overexposure problem. You need to use a combination of primary corrections, curves, LUTs, and secondary corrections. Be patient and work through the steps.

Mistake 2: Overdoing the contrast. When you bring down the highlights, it is tempting to also increase the contrast to make the image pop. But if you push the contrast too far, you will crush the shadows and create a harsh, unnatural look. Keep it subtle.

Mistake 3: Ignoring the scopes. Your eyes can deceive you, especially if your monitor is not calibrated. The scopes give you objective data. Use them.

Mistake 4: Forgetting about noise. When you darken an overexposed image, noise becomes more visible. Always check for noise and apply noise reduction if needed.

Mistake 5: Not shooting with exposure in mind. The best way to fix overexposed footage is to not overexpose it in the first place. When shooting in S-Log3, use your camera's zebras or waveform to make sure you are not clipping the highlights. Expose to the right, but not so far that you blow out the image.

Final Thoughts

Fixing overexposed S-Log3 footage in DaVinci Resolve is a skill that every video editor should learn. It is not always easy, and some footage is beyond saving, but with the right tools and techniques, you can often rescue clips that look hopeless at first glance.

The key is to work methodically. Start with primary corrections to get the overall exposure in the ballpark. Use curves and LUTs for more precise adjustments. Apply noise reduction to clean up the image. Use secondary corrections to fix specific areas. And always check your work on scopes and different displays.

With practice, you will get faster and more confident. Over time, you will develop an eye for what is recoverable and what is not. And you will be able to turn even the most challenging overexposed S-Log3 footage into something that looks clean and professional.
