Yesterday, I wrote a few tips for getting a perfect exposure of a snow covered landscape (or, how to avoid the “gray snow problem”).
But, what do you do with all those gray snow photos you already took? Throw them away?
Nope! Fortunately, there’s an easy way to fix the gray snow problem in Photoshop. With just a few clicks, you’ll transform that dull grayness into a beautiful bed of white textured snow.
Here’s how to do it:
Starting with this photo…
1) Add a new levels adjustment layer, by going to the “Layer” menu, then the “New Adjustment Layer” submenu, and finally select “Levels…”
2) Name the layer if you’d like, and hit “OK.”
3) Click on the “white eyedropper” button (circled in the screenshot below):
4) Here’s the part where you’ll have to do some experimenting. While keeping this window open, click on a part of the photo that you think represents the brightest white (anywhere on the snow should be a good first guess).
5) You might now see some blown out highlights, like this:
6) To get rid of those blown out highlights, just keep clicking around the photo (but only click on parts you think should be white), until you get a photo with just a few sections of blown highlights (they’ll look like bright white circles or blobs).
7) Keep clicking with the eyedropper towards the center of these circles/blobs, until it’s gone, and you’re left with a nice textured bed of snow, like the one here:
You may also want to zoom in on the photo before adding the adjustment layer, to ensure you don’t create any subtle blown out highlights.
Only use this method as a last resort!
With the wonderful power of tools like Photoshop, it’s tempting to get lazy out in the field (not thinking about exposure) and just say to yourself “eh, I’ll fix it in photoshop later.” Always remember that any post processing you do in Photoshop (or any other program) will significantly add noise to your photo.
