Photoshop tutorial: Colouring smoke - You've taken the pictures now add a little bit of colour to your incense smoke images in Photoshop.
Adding one colour
Step 1: Duplicate the background layer
Open your image up in Photoshop.
Go to the layers palette rename the layer and copy the layer by dragging the layer onto the new layer icon or by going to the layers menu and selecting duplicate layer. The original Background Layer is left untouched so if you get into trouble you can easily start again.
Step 2: Brighten the smoke
If you want to brighten the smoke slightly go to Layer> New Adjustment Layer>Levels to open the histogram or by clicking the black and white circle in the layers palette. If you click on the white arrow to the bottom right of the histogram and drag it to the left the image will brighten. Keep an eye on the background when you do this as you don't want to lighten this so much that the black begins to disappear and white specks appear.
Step 3: Create Hue/Saturation adjustment layer
Next we want to create a Hue/Saturation adjustment layer which you do by going to Layer>New Adjustment Layer>Hue/Saturation. When a new window opens you can simply move the hue slider up or down to vary the colour. For more variety click the colourize box and when you move the slider this time you'll notice there are more colour options. On our image, changing the hue value to -39 turned the image green while +45 turned it purple. Adjusting the saturation will give the image more or less punch.
Once you've done this and are happy your image is complete.
Changing a black background to white:
Step 1: Change background colour
To change the colour of the background go to Layer>New Adjustment Layer>Invert.
Step 2: Change the smoke colour
This will change your background to white but your smoke now may be a colour you don't want it to be. To rectify this, if you're still working on the same image, go back to your hue/saturation adjustment layer and simply adjust the hue until you find a colour your happy with. If it's a new image go to Layer>New Adjustment Layer>Hue/Saturation and adjust as you did before.
Step 1: Add a gradient
To add a rainbow of colours to the image we are going to add a gradient fill layer. To apply the gradient you can go to Layer>New Fill Layer>Gradient. Here a new window will open. In the window that opens you'll see you can adjust the angle, style and scale. There's also a box called gradient which has the current gradient style in it. To change this simply click on it to open the gradient editor. Once you're happy with the selection click OK.
