Candle Lighting with Photoshop

Most interiors with candles for adding ambiance, are anything but controlled. HVAC, opening doors, ceiling fans in another room or even an assistant or client walking in the room can make flames flicker resulting in motion blurred fire. The room may have a lot of ambient light that can’t be controlled so the slow shutter speed required to capture a vibrant flame can’t be used. Open flames on a set can be a safety hazard. Candles dripping wax can cause an unsightly mess that is really hard to clean up before making the final photo of an interior. What to do? Read on…

Candles & Interiors

Candles burning in an interior add warmth. They make the scene more inviting. They are an uncontrollable pain to shoot. So I never shoot burning candles in an interior. I do ask permission to light them. Don’t assume that it’s OK to light candles that happen to be in a room you are shooting. They may be just for decoration and replacing them with new ones can be problematic. Once I’ve lit a candle and the wick has blackened I blow it out. Why? Adding flame to unlit candles looks weird and wrong. I’ll show you one later so you can see what I’m saying.

Light Those Candles

Open an interior with unlit candles in Photoshop. Now open a photo of a burning flame too. A recent post of mine here on Photofocus, explains how to photograph a lit candle in a controlled setting.

Step one: Add the flame to the interior

In Photoshop, tap the V key to choose the Move tool in the toolbar. If your flame has more than one layer, highlight the appropriate ones in the Layers panel. Click inside the flame photo (not the layers) then drag it to the tab holding your interior. When the interior appears, drag the cursor into the photo. Release the mouse button to copy the flame into the interior as an new layer. If you want it centered, add the Shift key before releasing the mouse. A screen shot show the flame almost ready to light the candles.

Step two: Lose the black background

Normally this is where you are told “use your favorite selection tool to pull the flame off of the background.” Bother. This is much easier. Anytime something is photographed against a totally black background, change the layer’s blending mode to screen and the black disappears!.

Step three: Size and re-position the flame

Highlight the flame layer. Press Command (WIN: Control) + T or choose Edit > Free Transform. Click inside the bounding box. Drag the flame to one of the candles. Center the glowing wick on the end of the wick to be lit. Drag the anchor in the center of the image to the glowing wick. Next, Hold down the Shift key to keep the height and width proportional. Add the Option (WIN: Alt) key to make the transform happen around the anchor point. Click the Commit check mark in Photoshop’s Options bar to apply the transformation.

Size the flame’s wick centered on the candle’s wick.

Step four: Light the rest by copying the first

The flame layer is still highlighted in the Layer stack. The Move tool is still active in the Toolbar. Hold down the Option (WIN: Alt) key. Click in the flame then drag it to an unlit wick. Repeat to light all the candles. This technique keeps the candles brand new no matter how long the photography takes in real life. Even if you could burn the candles and photograph them in the interior, they’d never look this fresh.

The candles are lit!

As promised, here’s why you want to burn the candles being photographed until the wicks darken. As I said it look very weird and totally wrong!

Shoot some bonfires. This technique works to light fireplaces too!
