I assume that you’re here today to learn how to make rain in Photoshop. And well, that’s what we’re gonna learn today.
Start out with an image that you think might fit.
I’ve chosen this one: http://img704.imageshack.us/img704/9490/gmflatgrass20080001.jpg (Courtesy of ChestyMcGee)
As you notice, the picture is way too sunny for rain to be fitting. Here’s how you fix it:
First, add some color balance (Image>adjustments>color balance). You may wanna play around with this, but i reccommend adding some red, blue and magenta.
But wait, you say! This is still very unrealistic! That’s where a gradient map comes in. Create a new transparent layer, fill with 50% gray and change layer blending mode to ‘overlay’
Then, add a gradient map (Image>adjustments>Gradient map). Make it dark blue>light blue. You may also wanna play around a little with this.
Now, to the rain part create a black or white layer. Add noise (gaussian, monochromatic, ammount 400). Change the
layer blending mode to ‘screen’. It looks quite bad. So add some motion blur. I want my drops to be long, so I use a fair ammount of motion blur.
Apply the motion blur. Now, at the top and the bottom, you have these ugly edges, you’ll want to make those dissapear. So, press CTRL+T on the rain layer, and drag them outside the image.
Now the rain still look pretty bad, there’s too much. So, we’re gonna change that! Go to Image>Adjustments>levels and drag the black slider untill you think that it fits. The rain looks very sharp at the moment, so we’re gonna apply some gaussian blur to the rain layer.
Not much, just a little bit. If you’ve done it right, you should be done by now! You might wanna add some layer masks, and remove certain parts, if you find them unfitting, and you may wanna duplicate the layer so it becomes more intense. You may also duplicate it and make it smaller/bigger to create more depth.
That’s about it, if you have any questions, feel free to post them in the thread or PM me.
