How to Boost the Dynamic Range of an Underexposed Portrait in Lightroom 4
Often times we shoot images underexposed in order to preserve highlight detail when we don’t have additional lighting modifiers available. However, regardless of whether an image was intentionally or unintentionally underexposed, the production process remains the same.
This is a step-by-step tutorial that will show you how to correct for underexposure and increase the dynamic range of an underexposed portrait.
Lightroom 4 Preset System Mixology
If you own the SLR Lounge Lightroom 4 Preset System, this effect can be achieved in around 10-20 seconds. If you don’t own the preset system, please skip to Step 1 to learn how to do it manually.
Boosting the Dynamic Range
1. MY MIXOLOGY > 25 HDR Strong
2. BASE ADJUSTMENTS > 07 Lighten +1.5 (Exposure)
3. BASE ADJUSTMENTS > 23 Light Soften Skin (Detail)
4. BASE ADJUSTMENTS > 34 Medium Boost (Contrast)
5. ADJUSTMENT BRUSHES > 12 Sky | Cloud | Ocean (Detail Enhancers)
6. ADJUSTMENT BRUSHES > 13 Nature | Color (Detail Enhancers)
7. ADJUSTMENT BRUSHES > 16 Unenhance HDR (Skin) (Detail Enhancers)

The Original Image
Step 1. Applying our Basic Adjustments
Because the image that we started with is very underexposed, one of the first steps that we need to do is to correct the exposure. In this case, the image requires a +1.5 stop in exposure compensation. We also want to boost the dynamic range of the image, so let’s bring down the Highlights and Whites by -80 and lift up the Shadows and Blacks by +80.
Additional Contrast is also needed because when we increase the dynamic range, the contrast becomes flattened.
Because we are working with a portrait, we want to have nice, smooth skin tones. So let’s decrease Clarity a bit. Your Basic Panel adjustment and image should look like the following:
Step 2. Adding Additional Contrast via Curves
In addition to adding Contrast in the Basic Panel, let’s add a slight contrast-boosting “S” curve that pulls down the shadows a bit and boosts the highlights up a bit.
Step 3. Sharpening and Noise Reduction
Normally, if you are using the SLR Lounge Preset System, the Sharpening are automatically applied. Here are the standard sharpening settings typically applied to our images:
Notice that we applied some Noise Reduction because we added a heavy boost in dynamic range and pulled up our shadows. We use this setting for Noise Reduction:
Step 4. Opening up the Borders with Vignetting
Finally, let’s add some Lens Vignetting at +30 Amount and +30 Midpoint to even out edge-to-edge brightness.
Here is how your image should look like after applying all of these adjustments.
Once we completed all the global adjustments, we are now going to use the adjustment brushes for fine-tuning certain elements of the image.
Step 5. Using Adjustment Brushes for the Sky and the Ground
In the Lightroom 4 Preset System, there is an adjustment brush called the “Sky | Cloud | Ocean” that we would apply to the sky, cloud, and ocean. The purpose of this brush is to increase the contrast and clarity. Additionally, this adjustment brush also increases saturation.
Here are the settings for this adjustment brush, followed by the image with the brush applied to the sky:
We are also going to use a similar adjustment brush for the grassy field. The LR4 Preset we use is called “Color | Nature.” The settings for the brush are designed to boost the tones and colors typically found in nature. Here are the settings for this brush, followed by the photo after we applied this brush.
Step 6. Using an Adjustment Brush for Skin Tone Correction
One of the drawbacks of using an HDR-like dynamic boost in a portrait is that the skin tone may become over-saturated and may exhibit unnatural color shifts. We can use an adjustment brush to counteract these effects. The LR4 Preset brush we use is called “Unenhanced HDR (Skin).” This brush diminishes the contrast, clarity, and saturation on the skin.
This is how the skin tone looks before and after we applied the brush.
Final Before and After Images
Finally, here are the before and after images comparing the original underexposed image against the finished image with the boosted dynamic range.
