Open Photoshop and add the photo to which you want to add a snow effect.
SelectLayersto bring up the Layers Palette, and then select theplus signto create a newlayer.
go for the new layer.
Select theEditmenu from the top and then selectFill.
From theContentsdrop-down menu, selectBlack, and then selectOK.
The image will turn black.
We’ll now transform this layer from black to “noise.”
SelectFilter>Noise>Add Noise.
In theAdd Noisedialog box, underAmount, use the slider to create the desired amount of noise.
It’s completely up to you how much noise you want to add.
SelectGaussianand place a check next toMonochromatic.
To make the noise look more like snow, go to theFiltermenu and selectBlur > Blur More.
The photo may resemble pavement at this point, but we’re on the right track.
From the top menu, selectImage>Adjustments>Levels.
Move the white slider in from the right until it measures about 181.
SelectOKwhen you’re done.
The noise should begin to look less like pavement and more like a starry night.
Your image will become visible again, along with some snow overlaying the picture.
In theMotion Blurdialog box, choose your snow’sAngleandDistance(how much it’s moving.)
SelectOKwhen you’re done.
In this example, we set the angle to 300, making the snow come from the right.
We set the distance at 10 pixels to give the impression of a fierce storm.
Fewer pixels would lighten the storm.
Experiment and play around with your prefs until you get the desired effect.
To add more snow, choose the layer in the Layers Palette, and then selectLayer>Duplicate Layer.
Alternatively, right-punch the layer and then selectDuplicate.
Name the duplicate layer and then selectOK.
To make the snow layers look less uniform, we’ll move the layers around a bit.
Select one of your duplicate layers in the Layers Palette, and then selectEdit>Transform>Rotate 180degrees.
For a more natural look, select another snow layer, and then selectEdit>Free Transform.
Drag the layer around until it looks sufficiently random.
If the snow obscures your subject’s face, erase a bit of it.
This won’t affect the subject’s face because the subject is on a different layer.
Enjoy your final snowy image!
