How many times have you taken a photo with your digital camera only to have the flash not fire – either due to backlighting or a wrong setting? Well don’t think that your image is a total loss just yet. Try using the Shadows/Highlights adjustment in Photoshop (Image>Adjustments>Shadows/Highlights). Drag the Shadows slider to the right and watch how it adjusts the lower lighted areas.
This adjustment can pick up even the most minute differences in tonal values. One of the examples I show in my Photoshop class is a hidden easter egg inside of Photoshop CS3 (sorry not going to ruin the surprise) which comes from a 1% cyan value hidden inside of the feature.
So good luck and good Photoshopping.
