Common photo problems and how to fix them in Photoshop: #3 My photo is overexposed!

It's easy enough to fix underexposure in Photoshop, so surely it should be just as easy to fix overexposure? Not quite! For digital cameras, overexposure is a much more serious problem because highlight detail is very fragile – and once it's gone, you can't get it back. This is why we always recommend photographers shoot raw files – raw files have just a little extra exposure leeway that can allow a small amount of highlight recovery.

Welcome to the third instalment in our a 15-part series on how to fix photo problems in Photoshop, Lightroom and Adobe Camera Raw.

It's aimed at all photographers learning how to use Photoshop, Adobe Camera Raw and Lightroom to enhance their photos, but we hope it's going to be especially useful to photographers who find themselves stuck at home during the current coronavirus crisis. Let's look on the bright side – now's a chance to do some of the image-editing tasks and experiments we never had time for before!

In this instalment we'll show you how to correct a photo that's been overexposed. It's a simple enough job if you took the precaution of shooting raw files.

Oh dear. Our original image is clearly way too light, and we've started losing detail both in our model's skintones and especially in her woollen hat. (Click the gadget in the top right to see a full size version.) (Image credit: James Paterson)

Exposure and Highlights

If an image is too bright for your liking, you can use the tonal tools in Camera Raw/Lightroom to darken it down. The Exposure and Highlights sliders in the Basic Panel are a good place to start.

As long as the highlights aren’t clipped to pure white, there will be detail in the brightest areas that you can recover (especially if it’s a raw). Some photographers like to overexpose on purpose, or ‘expose to the right’—while being careful not to blow out or clip the highlights—then recover the image afterwards. This ensures the minimum of visual noise.

Jargon buster

Highlight recovery: This is a technique used when processing raw files. You can adjust the processing to recover very bright highlight areas that would otherwise have been 'clipped' or blown out.

Expose to the right: This is a technical trick used by some photographers to get the maximum theoretical quality. It means choosing an exposure that pushes the image histogram as far to the right (the highlight end of the scale) as you dare. The more light the sensor gets the better, though the more likely it is that you will end up clipping the highlights. For the small theoretical gain in quality, we think it's just too risky.
