I know some may have a bit too much snow at the moment but if you want to add some to that nice landscape you took in the summer here's how...
False Snow
1 : Open suitable image. Use eyedropper to select a mid-tone for the
area/objects you want standing snow on.
2 : Select > color range select sampled colour and a fuzziness setting about 130- 135
3 : New layer. (name it ?snow?]
4 : In new layer Edit > Fill select White. tip this wants to be a cold white so either add some blue using colour balance or use a blue filter from the photo filters.
5 : Ctrl+ D to deselect layer
6 : In layer palette change mode to ?hard light? > OK
7 : New layer [ snowfall #01]
8 : Edit > Fill > contents 50% grey [ again try a blue white and different %ages]
9 ; Use ?D? to revert this layer to default black & white colours.
10 : Filter > noise > add noise
11 ; Select gaussian, amount between 130-160, check mono box. > OK
12 ; This noise needs clumping together so use filter > blur > gaussian blur
with a radius between 3 and 6.
13 : Using levels adjust the contrast of the snowfall layer. Adjust the LH slider to the right so that is under the centre of the histogram peak; now bring the RH slider so it just shows behind the LH pointer. It is important to do this step in this order. > OK
14 : Set the mode of this layer to ?screen? with an opacity of 50% or less so the main scene shows through but the snow is still visible.
15 : Now blur the snow Filter > blur > motion blur. Select an angle that suits the image; try one not far off vertical; and a distance between 8 and 16 depending how blurred you want your snow.
16 : Duplicate the above layer Ctrl+J [snowfall #02]
17 : Edit > transform > flip horizontal
18 : Edit > transform > scale or distort and enlarge this duplicate layer so the snow flakes are larger than the original snow layer. > enter to lock the transformation.
19 ; You may wish to alter the motion blur on the duplicate layer. Try a negative angle with a value similar to the one used above, again the distance setting is to your preference.
20 : You may now have to adjust the density of the background layer and/or the opacity of the snow layers to get the desired effect.
You should have 4 layers
Steps 1- 2 Steps 3 ? 6 Steps 7 ? 15 Steps 16 - 19
