With most any photo correction or retouching there are always a variety of ways to do it. And when it comes to photos that are overexposed or underexposed, it’s no different.
But this technique is so quick and easy, I hesitate to even call it a tutorial. And it can be done in Photoshop CS and Elements. It doesn’t always work with every photo, but it’s definitely worth a try. And when it does work, you can achieve these kinds of results in a matter of a few seconds – literally.

I should point out, these are just a couple of random photos that I pulled to illustrate this technique.
Are you ready? Okay, here we go.

Overexposed:
1. Open your photo and duplicate the layer
2. Set the Blending Mode to MULTIPLY
3. Adjust Opacity if needed (Opacity is to the right of the red circle)
That’s it. Nothing else to do.
However, as you can see in this example the original photo was extremely washed out, so I just duplicated the layer a second time and set the both layers to MULTIPLY.
And for a photo that’s underexposed, it’s just as easy. Only this time you’re going to set your Blending Mode to SCREEN.


Underexposed:
1. Open your photo and duplicate the layer
2. Set the Blending Mode to SCREEN
3. Adjust Opacity if needed
As before, because the photo was so dark I duplicated the layer a second time and set the both layers to SCREEN. Also (as seen in the comparison photo) I went in and enhanced the window a little using the technique in this tutorial. Quick Fix: What’s outside those overexposed windows?
And if you want, you can always go in to your colors, or contrast, levels, or whatever you like to tweak it a little more. But that’s all there is to it. And keep in mind, there are a variety of ways to correct exposure issues, and this is just one of the more simply methods.
Hopefully you find this helpful.
