Helpful Tricks for Restoring an Under Exposed Image in Lightroom

We’ve all done it before. After downloading your shots of the day to your computer, you come across a badly exposed image and your first impulse is to send that file to the trash can. But what if it’s a shot you really wanted? Is there a chance you can save it? Using some of the common tools found in Adobe Lightroom, there’s a good possibility that you can.

My scenario was that I was walking in San Francisco and saw a street performer. After getting her permission, I very quickly snapped a few shots, then moved on, not wanting to distract her from her growing audience. It was only later, reviewing my shots at home that I realized how a bright background caused me to badly underexpose her. What tricks does Lightroom have to fix mistakes like mine?

Restoring an Under Exposed Image in Lightroom

Step 1: Apply Fill Light and Recovery.

When it comes to adjusting exposure, Lightroom has four sliders to help you: Exposure, Recovery, Fill Light and Blacks. Where Exposure controls the global exposure of your photo (and therefore may push correctly exposed areas into overexposure), Fill Light controls the exposure of only the darker areas of your photo. Think of it as shining a light into the darker parts of your photograph and lightening them up. In my example, the subject is very dark, so I needed to apply quite a bit of Fill Light to brighten her up.

Recovery is the opposite of Fill Light: it “recovers” details in the overexposed areas of your image. Honestly, there’s not a huge amount of detail that can be recovered from severely overexposed parts of your photograph, so if you must err, err on the side of underexposure. Still, recovery can help bring back detail you might have pushed into overexposure by adjusting the global Exposure slider. Experiment a little and see if you can find a good balance.

Step 2: Tweaking the Tone Curve

Things are looking much better already, but we can take this a little further. The Tone Curve is a visual representation of the exposure in your photograph with black at the far left and white at the far right. Physically moving the curve takes some expertise, but using the sliders underneath the graph is something even a beginner can do easily. Each slider is assigned to a specific part of the tone curve: Shadows, Darks, Lights, and Highlights. The tone curve affects exposure much like the prior settings do, but on a more subtle scale. Here, you can tweak the exposure to get the shadows just a little deeper and the highlights a little less bright.

What you want to keep in mind here is that “Darks” is probably the slider that refers to your subject, at least when your photo is underexposed. So for our example, we want to move the Darks slider up into the positive side of the scale, which brightens up the subject even further. I’ll leave the Lights slider alone and slide the Highlights slider down into the negative numbers, which helps further reduce the overexposure of the background sky and building.

Step 3: Restoring the Color Balance

By now, we’ve pretty much nailed the exposure, but because shadows tend to be cool in color, the color balance of my photo is still not very pleasing. Not to worry. At the very top of the Lightroom workflow is the global color balance sliders, which are two sliders; one is blue and yellow and the other is green and magenta. Using these two sliders, you can tweak the color to whatever is pleasing to your eye. For my photo, I pushed the blue/yellow slider way over to the yellow side and added a little more magenta to restore my subject’s skin color.

Shadows also take a lot of “punch” out of colors, so Lightroom can help restore some of that. A little below the color balance settings there is a section called Presence with three more sliders: Clarity, Vibrance, and Saturation. What’s the difference between Vibrance and Saturation, you might ask? Think of Saturation as a global color boost, affecting the saturation of all the colors in your image. Vibrance, on the other hand, boosts the saturation of only the less saturated colors in your image. To put it another way, Vibrance is the scalpel while Saturation is the chainsaw. In my sample image, where so much color has been muted, both Saturation and Vibrance can be adjusted. Start with Saturation and make the subtle adjustments with Vibrance.

Other techniques to improve color can also be applied such as split tones and graduated filters, but those are beyond the scope of this particular tutorial.

Step 4: Cleaning Up the Noise

Sometimes when you bring too much detail back into the darker areas of your image, it results in a lot of “noise” in those areas. This noise is characterized by blotchiness or sometimes off-colored areas that are extremely blue, green or some other color. The degree of noise depends a lot on the quality of your camera’s sensor and frankly, you can’t always completely clean up all the noise in a particularly bad image. Lightroom 3 has some fairly powerful noise reduction filters, much better than what it had previously in Lightroom 2.

Noise reduction in Lightroom 3 consists of two sets of three sliders, one for Luminosity and one for Color. Luminosity noise reduction is usually the most effective because much of noise created from lightening up the dark areas is luminosity noise. You can usually get away with playing with the Amount slider and leaving the others alone. Don’t over-do it on the noise reduction or your images will start looking more like paintings than photographs.

So that’s it. Another photograph saved from the trash bin. With a little practice, you need not fear underexposure ever again.

    This is a really good guide to help people out. I have used those techniques more than once and saved images.

    very greate

  3. Very useful article!!!

  4. John Dunne says:

    Looks like the information is pre Lightroom 4, which was the first version I got. So it was, initially, slightly confusing.

  5. Mark C says:

    This is a great explanation of how to recover the underexposed photos, however this is based on Lightroom version 3 and 4.4 is out and 5 is on the way. The basic tools in 4 are much improved and the same result can be accomplished. Thanks for taking the time to show us how to do this

  6. JC Ruiz says:

    I find that the biggest issues with underexposed images is the noise in the shadows after you bump up exposure in Lightroom. I find that using Nik Software Dfine is better at getting rid of the noise better than Lightroom can

  7. R. Moreno says:

    That color in the final image looks like the chainsaw ran away with the saturation slider.
    The best trick for these sorts of images is setting your black down to zero or at least a lower number than default 5… that will rid the photo of the appearance that you went too high on the clarity slider like in these examples. Then adjust your tone curve if you want to get a punchier black, had it been opened up too much. Above all else, learn how to evaluate these scenarios and get better exposures instead of just letting your unintelligent camera make these bad decisions on your behalf.
    I’d like to see a better example where this is necessary, like when you have no time to adjust in order to catch that decisive moment, not when you stop, ask someone to take their picture and have the time to turn the wheel a few clicks over.

  8. Julio César says:

    How can I do to see Recovery, Fill Light and blacks under exposure slider? I don’t know how to enable them

  9. fan says:

    hy there I want to ask, I have two different images that lighting is one which tends to be darker and one lighter, I would like to equate it, how? thank you
