Sasa,
I hope you do not mind but I have 'played' with this lovely photo. If you would prefer me not to do this , just say.
As Sharon (sassy) says the snow is blue.
Using PSP XI I done the following:
1) Adjust> Colour Balance> move the slider to warmer.
2) Adjust> Brightness & Contrast > Clarify > setting 5
3) Adjust> Sharpen> Sharpen more (x1)
3) Adjust> Hue and Saturation> Saturation to level 30
I cloned out the branch behind the sledge.
I put a border and signature for fun.
OK?? ~ John
PS - I like snow...................when I am indoors in the warm!!!
