Burn Baby, Burn!
(Adobe Photoshop 7 Effect Tutorial)
Create a fiery foreground in ten minutes or less! Well, after the first try ;D
5: Right now, you're pretty much done with manipulating the fire to how you want it to look, so set the top layer to "Lighten" with an opacity of 90% and you get the image on the left. While "Lighten" is my preferred setting because there is definition to the flames, the settings "Screen" and "Multiply" also work, especially if you're going for a dark fire-look. It's up to you!
6: This final step is entirely optional, but it adds the little details that make your fire a bit more hypnotic. Between the two fire layers, add a new blank layer. On this layer, use a scattering brush to create little particles like ashes or embers in white. Then go Layer > Layer Style > Outer Glow and select a yellow or other warm color. Increase the Spread distance too on the layer style menu for a greater glow. Click the image to check out the final product! Experiment and have fun!
