Photoshop Tutorial : Lets make it rain
Perhaps you want to composite some images together to make a scarey, stormy image. Or maybe you have an image that has storm clouds, is dark and overcast and would benefit with some rain added to it – or maybe some snow for that winters scene.
Start and Finish Images
Using a couple of filters and a blend mode in PS you can create away to your hearts content. The image I’ve used in the tutorial is 800 × 600 @ 72 dpi You will have to adjust some of the settings that I am going to use to compensate for a larger image and dpi, but I know you like to play in Photoshop 🙂
Firstly, open your chosen image, duplicate it and close the original. If you just want an image to practice on, you will find the start file HERE
I’m using PS3, so my next step was to use a B&W adjustment layer to convert this particular image to B&W, I then used a Curves adjustment layer and then a Levels adjustment layer. You don’t have to convert to B&W, I just chose to do so because the original image sucks 🙂 How you want your image to be is fine, it is not going to affect what we are going to do next.
So, whatever it is that you have done make sure that the top most layer is selected then I want you to create a new layer above. You can click on the new layer icon in the layers palette, or you can press shift+ctrl+n to bring up the new layer dialogue box and name the new layer. Now I want you to fill the new layer with black. If your f/ground and b/ground colour are set to the default you can press alt+backspace on your keyboard for window users and I’m not sure for mac users LOL probably option backspace. Now is starts to get fun.
Making sure that you new black layer is active, I want you to go to Filter>Noise>Add Noise – below are the settings that I have used on this image, so punch in the same settings if you like.
Go straight to Filter>Blur>Motion Blur and you can apply the settings that I have by punching in the same figures as the image below. If you want the rain to go straight down, or from a different angle altogether, just rotate the little angle wheel around till you get want you want.
Next I want you to go to Image>Adjustments>Levels. In the image below you can see what the starting point will be for this particular image. I have made no adjustments as of yet.
By bringing in the black slider toward the middle of the bar we start to creat the rain. The rain will be the white lines that you see in the image. You can see in the image below that I have taken the black slider in toward the middle and I have also moved the white slider in toward the middle slightly. How much you move each slider is entirely up to you. It will depend on how much rain you want in the image etc., So that’s the part where you get to play around because each image will require slightly modified settings.
Right, so thats a mess LOL But, here comes the great part. Go to the Blending Mode option at the top of the layers palette and I want you to change it to Screen ….. look at that ….. magic! 🙂 Screen mode knocks out any black pixels and the multiply blend mode is the exact opposite to Screen if you want to knock out white pixels. All that is left to do now is change the opacity slider if you want. I’ve changed the opacity to 50% in the image below.
