Filter > Render > Flame

An Adobe Photoshop often forgotten filter

Fire is a very popular digital substance these days. There are photo art actions that will set any subject on fire. There are photos of fire carefully extracted and served as PNG files to graphic artists. And there are well-known paint programs and 3rd party filters, such as Alien Skin’s Eye Candy, that offer their renditions of fire and flame. However, Photoshop itself has been offering a way to render flames since at least CC 2014. It is no longer available as a scripted pattern fill (Edit> Fill), but now solely resides in the Render menu, along with Trees, Frames, Clouds, Lighting, and more. Many of us tend to forget that the Flame filter even exists. The other day  I remembered it when I wanted a few flames for an art journal page, and decided to reacquaint myself, so I created a simple image to walk through the process and share with you—just in case, like me, you tend to forget how something works when you go a long time without using it.

To use the Flame filter in Photoshop, you first need to create a path. The Pen tool is the obvious method for drawing a path, but for those of you who find the Pen tool intimidating, you can also use a Shape drawn with the Path setting in the Options bar. The main limitation to using a Shape is that it’s always a closed path that encloses empty space, even if a very narrow empty space. It will still generate flames, but it won’t look the same as a flame drawn with the Pen tool. However, that’s not only not always bad, but using a shape is also a quick way to produce an image if you want a burning heart (or house or. . . ).

Flames created with Shape and Pen tool paths
Although the Flame filter requires a path to operate on, you can create a path using a custom Shape layer in Path mode, (left), a basic shape such as Line (middle, or create a path with the Pen tool (right). The Direct Selection tool is used to modify both Shapes and Pen tool paths.
Adding the first layer of flames
Several open paths on the same path layer were used to generate these flames using One Flame Along Path as the Flame Type. Only one slider is in play in this mode on the Basic tab, but you can choose a custom color. Paths shown were stroked with a magenta Pencil on a separate layer for visibility in the screen shot only and were not visible in the final image.

Once you’ve drawn your path (multiple paths can reside on the same layer), it’s a good idea to save your path layer by double-clicking on it and naming it. You’ll probably want to be able to return to it to adjust or use for another flame. Next, create a new, empty layer—the filter always returns pixels and won’t run as a Smart Filter, so protect your image from a destructive operation. With the path active in the Paths panel (you can see the path in the document window), and the empty layer targeted, choose Filter> Render> Flame. . . . In the dialog, experiment with the different settings in the Flame Type list and their sliders to see what looks best. You can also select a custom color for your flames.

New Flame type rendered to image file
After adding in the background (a paper from Holliewood of Mischief Circus), and modifying the logs with a style and overlay, two horizontal, wavy paths on a single path layer created the small ember flames using Multiple Flames One Direction for the Type.
Initial image with 2 separate renders
After rendering both types of flames, this image using the default color provides a start to further exploration of the filter’s capabilities.

Once you have constructed a flame type that you think is very close to what you want, you can choose the Advanced tab to modify the results even more. Most of the settings here are subtle, although some can make a significant difference in the result. For this demonstration, I only used the Basic tab, which in many cases is all you’ll need. Click OK to render the flame(s). Now you can deselect the path in the Paths panel and create another path, or several more paths, on separate layers, to complete the image of your object on fire. For my example, I rendered different flame layers using different paths, and used custom colors, blend modes, and opacity. Where necessary, I modified the paths while looking at the rendered flames on a layer, then turned off the layer, created a new one, and re-ran the filter. I also used Free Transform on rendered flame layers to help them fit the image better.

Two renders of one flame type with different settings
The Flame type Multiple Flames One Direction makes use of several sliders to determine the length of the flames, their width, and their spacing. Shown above is the result of rendering the same flame type two separate times, but using slightly different settings, custom color, blend modes and layer opacity.
Last version shown with and without the paths that created them
Multiple paths (shown top), along with rendering flames with custom color and settings, as well as adding in blend modes and layer opacity produced the image at bottom.

With its decent preview and straightforward sliders, Flame does a pretty good job for anyone who doesn’t need to add lots of flames to everything. If you want greater realism or an organic feel to your flames, building up your fire from multiple flame layers can get you closer than you might expect. But if you want a stylized graphic, this filter has got that covered, too. For occasional use, if you’re willing to toy with the sliders and adjust the paths, I think you’ll find it adequate for most purposes, without forcing you to think you have to spend a lot of money on 3rd party solutions.

"Daily Planner" series for Democrace with Flame render
Several designers—Rucolla, Lynne Anzelc, ViVa, and more—were used to create this “Daily Planner” art journal piece as part of a series for Democracy. The fire engulfing “Free and Fair Elections” was created very quickly in Adobe Photoshop CC with the Flame filter.
