Starlight Effects for Candles and Lights
Add extra sparkle to your candle and chandelier images by using an inexpensive starlight filter. You can even make your own, if you don't mind scratching a little glass

Candlelit rooms convey a romantic or sentimental mood for your images. All you have to do is steady the camera, trip the shutter, and play from there.

The thing with candles, however, is that the light they cast on your subject is often more interesting than the candles themselves. After all, how compelling is a little flame of light? You can add a little oomph to these images by using a star-effect filter, which takes a normal candle flame and turns it into a blazing star, as illustrated in .

This little bit of photographic trickery is accomplished by tiny etches in the glass that distort the light. If your camera accepts filters, you can pony up US$25 and start to play right away. One brand of creative filters you might want to take a look at is the Cokin System (http://cokinusa.com), which has star effects, gradual density, and special-effect filters. Cokin has adapters for every type of camera and lens, and it even has a special mount for cameras that don't even have filter rings, such as your digital point and shoot. I've played with the Cokin Star Effect #056, A Version, and have had good success, even on a Canon Digital Elph S400, which doesn't have a filter ring. shows how this rig looks.

You can also make your own star effects by taking an old UV or skylight filter and etching it with a glass cutter. I recommend you use a crosshatch pattern for your etching. This of course provides you with the opportunity to create unexpected results.
