I'm on the fence about this method. Maybe it's me, because I know they aren't originally winter scenes. But this is also my first attempt at it and I'm sure there are a few things I could do to make it a touch better. I'll have to play with them in the future, but this is the first try.
I've provided the original photo below the winter version so you can see what I started with.
Scroll to the end as I've listed how I created the winter feel to the photos.
So how did I make wintery?
1) Open the original image in Photoshop.
2) Click the Hue/Saturation button on the Adjustments tab above Layers.
-- You'll see the selection bar between the bottom two color scales. Make sure to include the colors you want. If there's green and yellows, like in my first image, I moved the center scales to include those colors.
-- Then, slide the Lightness marker to the level of "white" to appear.
3) If you need to bring skin colors back: click to make a new mask (while in this layer) which is the box icon with circle in it. Make sure your foreground/background colors are black/white. Then Using brush in size to your face(s) go over the people to bring them back out.
**If you have colors that still bleed through that you want whiter, create a new Adjustment for Hue/Saturation as needed.
Add Snow: (I downloaded different brushes so I have them in my brushes.)
1) Add new layer (the icon that looks like a piece of paper with bottom left corner folded up).
2) Click Brush and selected brush type and size. Then clicked on image. (Don't worry if cover people, you can remove that!)
3) To touch up faces and where snow is falling -- Click 'Add Vector Mask' then click brush and use regular brush. Brush over where snow not to be.
I downloaded brushes from different sites. The site with many links I found is Creative Bloq. This snow brush is from Brusheezy.
