Blend Exposures
The Blend Exposures filter in this collection is my favorite. It allows you to do two things. First, if you bracket your digital photos, you can use it to combine the best portions of an underexposed and overexposed image automatically. No muss, no fuss. Your underexposed image will provide the details in the highlight areas, and the overexposed image will provide details in the shadows. Here's how you do it:

  • Open both images in Photoshop.
  • On the first image, use the filter "Setup 2nd Image."
  • Then click on the second image and choose the filter "Blend Exposures."
  • That's all there is to it. The filter automatically determines the best values from each exposure and combines them into one image.

Three clicks, and you have results that are not only quick but great.

    But there's also another trick you can do with this filter that will apply to more of you out there who do not have bracketed images to work with. Let's say you have an underexposed or poorly lit image. You can trick the filter into thinking you're working with two different exposures and generate some surprisingly impressive results. The images below were created using this trick in just a few quick steps.



    The way you do this is exactly the same as above, except instead of using two images you simply use two states of the same image--the original and one that you've brightened up using Brightness/Contrast or Auto Levels or a combination of both. It's quite simple, and you can keep trying out additional blends off the same image for variation. As with the examples above, some variations might preserve the mood of the original photo, while others might brighten it up and change it entirely. Whatever the case, the results aren't half-bad for about 15 to 30 seconds of work.

    As a little added bonus, the filter works in 8- and 16-bit modes.
