Did you miss photographing the last heavy snow? Or perhaps you are not too fond of shooting outdoors in cold weather. Now you need a photo with snow falling. Don't despair. It's rather easy to add snow digitally to any photo, color or black and white, with programs like Adobe Photoshop (CS and earlier), Elements, or other image-editing programs. Furthermore, you can stop the snow in midair, as you would with a 1/125 second or greater shutter speed, or you can blur it a bit, giving it a slight motion trail, all in the cozy comfort of your home or office. You can even control the size and direction of the snow. There's no need for warm clothes, gloves, an umbrella or long underwear. All you need are a few minutes with your keyboard and mouse (or graphics tablet).



First, select the photo. Often, a slightly dark image will work well, but you can use normal exposures, too. Light or high key images, however, are less successful because their light backgrounds don't let the snow stand out. As to subject matter, this effect works with a wide range, from landscapes to cityscapes to portraits to evergreens, or holiday ornaments. I found that digital snow effectively enhanced landscapes that I had shot in the days after the snow fell, while it was still on the ground but not coming down.

Here are the ABCs of how to add snow to your picture. Always work on a copy of your original.

A. Open your chosen photo, #1, in Photoshop, Elements, or other image editor. Working in Photoshop CS, I started with a picture of a bridge in Central Park taken after a snow with the Canon Digital Rebel and the Canon 17-55mm lens.

B. Make a copy of the image by choosing Image>Duplicate. Save it to your desktop.

C. Working with the copy image, fill it with black by choosing Edit>Fill and the color black, #2. The image will now be totally black, #3.

D. Now it's time to get out the snow machine. Choose Filter>Pixelate> Pointillize, #4. For a high resolution image like this one (6x9" at 300dpi, 14MB file size), choose a Cell Size in the Pointillize filter dialog box of 5-8. A setting of 5 will create a moderate snowfall, while an amount of 8, shown here, looks like fairly heavy snow.

E. The Pointillize filter creates subtle colors, which, of course, are not seen in snow. To remove the color, choose Image>Adjustments>Desaturate. Now, the image on screen should be pure black and white, resembling heavy snow falling at night, #5.
