This week, Jack Howard shows us an easy hack to the SD14 to capture invisible light :
"By simply removing the infrared (IR) cutoff filter from this digital SLR, the camera gains the ability to capture IR plus visible spectrum images. And with the addition of an IR filter, you can go straight to IR-only capture."
He got some great pictures from it, including the one below.
But don't forget, monkeying with the insides of your new camera could void the warranty. Proceed with caution! This won't void the Sigma warranty, since it is designed to be removable to enable the user to clean the sensor.
