There are many ways to create snow in Photoshop. Here's the shortest one: simply click on the snow flurry. The Photoshop action first transforms your photo into an oil-colored image and then lets the snowflakes fall down. This is how you create enchanting winter images that can be the basis for Christmas greeting cards and gifts.
A magically automatic process for magically contemplative images: Get the Photoshop action and ask Mother Hulda for some fairytale snowflake magic with every click.
