How to Rescue a Poorly Lit Image with Photoshop’s Shadows/Highlights Adjustment

Photoshop’s Shadows/Highlights adjustment is the perfect tool for rescuing a poorly lit image. But what do all those sliders really do? Here, we’ll go through the adjustment process to see how we can make those options work for us.
Step 1: Open Shadows/Highlights
In this photograph of actor Emily Watson (courtesy of Caroline Bonarde Ucci, under Creative Commons) her face is in deep shadow on the left, but her shoulder is too bright on the right. The first step is to choose Image > Adjustments > Shadows/Highlights.
Step 2: Show More Options
The default settings show just two basic sliders, with the default set to 35% shadows. This brightens the dark areas to some degree, but it’s worth taking it further. Click the Show More Options checkbox at bottom left of the dialog to continue.
Step 3: Adjusting Shadows
Raising the shadows level makes the shadows lighter still; dragging the Tone slider applies the effect to a wider range of tones, so the midtones are boosted as well. The Range slider changes the range to which pixels are considered to be shadows; dragging too far on this slider produces artificial results, so move it sparingly.
Step 4: Adjusting Highlights
That shoulder is still too burnt out. Dragging the Highlights slider to the right darkens the tones in this area, but it also makes the shoulder look too gray.
Step 5: Tweaking Tone
Reducing the amount of the Tone slider in the Highlights section counters that gray appearance, while making the right side of the face look more natural.
Step 6: Using Color and Midtone Sliders
The image so far is looking brighter, but rather washed-out. Raising the Color slider gives her better skin color; raising the Midtone slider boosts the contrast and produces a much more appealing image. Remember, at any point you can click the Preview button to compare before and after. Click OK when you’re done.
Step 7: Grab the History Brush
The face looks much better, but now the hair is too bright. To fix this, switch to the History brush and open the History panel: click next to the Open item to pin the history at the starting point.
Step 8: Adjust the Hair
Paint over the hair with the History brush, in one single movement, to return it to its original state. It’s better, but it now looks too dark in comparison with the face.
Step 9: Using Fade
Open the Edit >Fade dialog, and you can drag the opacity of the last brush stroke to lessen its effect. Setting it to around 50% gives a good balance between the dark and light states of the hair.
The Final Image
Here’s the portrait before and after adjustment. It’s now significantly better, with good definition and balance between light and dark.
