Preparation
Since you want to edit a smoke photo, the very first thing you need to do is to prepare the smoke photo itself. If you have a smoker friend, you can ask him/her to be your model and take a photo of him/her. The end result of the editing process would be perfect if you use a black background on your photo. Bonus: Most essential GIMP shortcutsGetting started
- Launch GIMP and open your photo by going to File -> Open.
- Create a new transparent layer by going to Layer -> New Layer. On the appearing pop-up dialog, select Transparency on the Layer Fill Type section.
- With the new transparent layer selected, click the Blend Tool on the Toolbox panel.
- Set the gradient to "Full saturation spectrum CW".
- With the Blend Tool selected, click on certain spot on the canvas area and drag to another spot to apply the gradient (see the screencast below).
- With the transparent layer selected (which now has been filled with the gradient), go to Layer -> Mask -> Add Layer Mask. On the appearing pop-up dialog, select the Black (full transparency).
- Change the layer mode to Overly.
- Make sure the background color is black.
- Select Paintbrush Tool on the Toolbox panel and set the brush type according the smoke area you want to brush. You can use a combination of brush types and sizes on the brushing process.
- With the Paintbrush Tool selected, brush the smoke area. To recover the area you have brushed, you can use Eraser Tool.
- Once you are done with the brushing process, set the opacity of the transparent layer.
That's it. Following is the example of the photo I edited.
