Use Adobe Photoshop to add realistic snow effect to your pictures. Even if picture is taken in summer
All keyboard shortcuts are for PC. I don’t have a Mac, but as far as I know the main difference is use of the COMMAND key and OPTION key on a Mac instead of the CTRL key and the ALT key on a PC.
|Original photo. Northern Finland, not far from the polar circle:
Let’s try to add little snow to it.
Step 1. Duplicate background.
As usual, begin with pressing CTRL-J to duplicate “Background” layer. That will let you have a “backup” of the orginal image if something goes wrong.
|Step 2. Create “Snow” layer filled with white.
Press CTRL-SHIFT-N to create new layer. Give it a name “Snow”.
Press SHIFT-F5 to fill new layer with white.
|Step 3. Fill “Snow” layer with noise.
Select Filter – Noise – Add Noise.
Set Noise Amount to 100-150%, Gaussian distribution, Monochromatic NOT checked.
|Step 4. Increase noise size.
Press CTRL-A to Select All, then CTRL-T to Transform.
Use numeric input in the upper part of the window, set vertical and horizontal scale to 150-200%.
|Step 5. Set blending mode of “Snow” layer to “Screen”.
|Step 6. Convert noise to snow.
Use Image – Adjustments – Threshold. Set Threshold amount to 200-240, depending on how much snow you want.
Select Filter – Blur – Gaussian Blur. Set Radius to 0,5 – 1 pixels. Do not blur snow too much at this step.
My values are: Threshold – 243, Gaussian blur – 0,6 pixels.
|Step 7. Make snow fall.
Select Filter – Blur – Motion Blur. Set Distance to 8-12 pixels and try various directions.
|Step 8. Ideas for further adjustments.
