Creating Realistic Snow in Photoshop.
1. Duplicate Background (Layer > Duplicate Layer)
2. Create Fill Layer by going to Layer > New Fill Layer. Pick a dark gray color and place it between the two layers.
3. Replace sky - Magic Tool, create rough selection of sky; Then, go to Layer > Layer Mask > Hide Selection to create mask. With the layer selected, Properties panel > Mask Edge. With the Refine Mask window now open, you can brush on the image to refine the mask.
4. Add the new background sky, Gradient used to create clear sky.
5. Add a few layers to help blend the new sky with the background. Create a new layer (Command/Ctrl + Shift + N). Select the Brush Tool, pick a dark blue colour and paint over the trees. Name the layer Hue, set its Blending Mode to Hue, and its opacity to 35%.
6. Add a little bit of haze to further blend the trees with the sky. Create a new layer, pick the Brush Tool, and holding Shift, paint a straight line over the horizon. Duplicate layer twice, hit Command/Ctrl + T to enter the Free Transform mode and scale both layer up vertically.
7. Set all three layers to 20% opacity and name them Haze.
8. Start creating snow flakes. Start by creating a new layer (Command/Ctrl + Shift + N), then fill it with black (D, then Alt + Backspace), and then go to Filter > Noise > Add Noise. Then go to Filter > Blur > Gaussian Blur and apply the filter.
9. Using Curves, adjust the contrast of your layer to make it look like snow. Bring the left handle to the lower left corner of the pyramid, and the right handle toward the middle of the area. Then, click in the middle of the line to create a new handle, and drag it downward.
10. Name the layer Snow and set its Blending Mode to Screen to blend it with the scene.
11. To make the snowflakes more realistic, go to Layer > Blur > Motion Blur and play around with the settings until the desired snow look is achieved.
12. to achieve a more realistic snow fall, repeat steps 8 - 11 creating different sizes of snowflakes at different rates of motion blur each time.
How to Mold Paint Splatter to a Face in Photoshop
1. Duplicate background layer. Rename the new layer Subject and turn the background layer to white.
2. Create a new layer labeled "Extra Skin." Then using the Clone Tool, Alt-click on other parts of the face that best match the color of skin you want to copy. Use a soft brush to blur out the edges. clone over the eyes, mouth and nostrils.
3. Once all facial features are covered, merge the "Extra Skin" layer and the "Subject" layer. Rename this layer "Faceless Subject."
4. Create a new layer and call it "Paint map." Select the Brush Tool and start to paint out the area the paint splat is to appear in. This is where any paint splatter/spray brushes will come in handy.
5. Make sure that you only paint where you want the splatter to occur, you may have to paint/mask/erase a bunch to get a nice paint splatter. Take your time with this Step; it may be the most important one of the process.
6. Once completed you will want to get rid of any layer masks by right-clicking on the "Paint map" layer and selecting Convert To Smart Object. After that, change the layer style of the "Paint Map" layer to Overlay.
7. Next create a new layer under the "Paint map" layer, and name this layer "Extra Skin 2." With this layer selected Command-click the "Paint map" layer to select the paint splat you have created. Next click on the Add Layer Mask button at the bottom of the layers palette.
8. Turn the visibility of the "Paint map" layer off. With the "Extra Skin 2" layer selected, use the Cloning Tool again and copy portions of skin into the area that has no skin.
9. Again try to match the lighting of the photo; you are basically creating an extra skin layer that will become paint once coloured. Once you've created a nice splatter area made from skin, turn the visibility of your "Paint map" layer back on.
10. Create a new layer above the "Extra Skin 2" layer and name it "shadow." While holding down the Alt key, click between the "Extra Skin 2" layer and "shadow" layer to clip it. Grab a big, soft brush and paint some black to amp up the shadows needed for the "Extra Skin" layer. Turn the opacity of the "shadow" layer down to around 75%.
11. Create a new layer above the "Faceless Subject" layer and name it "Paint Background." With the foreground colour set to black, start painting some paint splats with the splatter brushes.
12. All we have to do now is add a little bit of shadow to create the illusion the paint is lifted off the face. First create a new layer and name it "Shadow 2," then Command-click on the "Paint Map" layer to select it. Making sure you are still on the "Shadow 2" layer, fill the selection with black.
13. Making sure the selection is still active, click on the Create Layer Mask button on the the bottom of the layer's palette. Select the mask for the "Shadow 2" layer and invert it by pressing Command + I, or going to Image > Adjustments > Invert. This should invert the mask and hide the black area we just filled. Disable the link between the mask and the shadow paint by clicking on the chain between the layer icon and the mask, as shown.
14. Make sure the paint portion of the "Shadow 2" layer is selected and go to Edit > Transform > Warp. Slightly adjust the shadow so that it peeks out from behind the paint splat. Depending on how much you want the paint to appear lifted, you can adjust it a lot or a little. Once you have the shadow right where you want it, apply the change.
15. You are bound to have some unwanted shadow from the "Shadow 2" layer; to clean it up, simply paint over what you don't want in the layer mask. Lower the opacity of the shadow to around 72%. done!
