My false photo...

I first opened the photo's i wanted to use to create my raindeer with berry twig antlers.

I then zoomed in and used the magnetic lasso tool to go aroung the twig and berrys..

I then erased the background, de-selencted the twig and used the rubber to remove the excess background.

I then repeated the same process with the raindeer.

Next i dragged the antlers onto the raindeer flipped one and resized them to fit and dragged the two layes below the raindeer.

I then opened the photo that i wanted to use as the background.

Next i dragged the raindeer on and re - sized it.

To make the falling snow i added a new layer on top  and filled it black.

Filter > noise > add noise, > 100% > tick gaussian and monochromatic ( make sure uniform is un checked)

Filter > blur > gaussian blur > radius 3.5

Enhance > adjust lighting > leveles (untill i got the amount of snow i wanted)

 I then changed the layer style to screen

Blur > motion blur > 65 degrees > distance 3 pixels

 

 

My final photo....
