New User - Adding snow to a scene ???

[carmen]

There is a 'quick and dirty' way to add/restore an 'it's snowing now' effect to an image:
1. add a layer over your picture and fill it with white
2. put the layer mode to 'dissolve' and decrease the opacity to around 3-8 (almost transparent), and now play with it:
3. shift-click the eye in the layers dialog to make it the only visible layer, Edit-->Copy Visible, undo the change, hide the added white layer and Edit-->Paste as...--> New layer in place. That gives the identical effect in normal mode, so that one can

• blur a little to made the flakes less sharp
  
• apply a motion blur to get a blizzard effect
  
• enlarge the flakes scaling up the whole layer
  
• delete/decrease visibility over people's faces...
  

Quite simple, quick and customisable.
