Summer is known for great fireworks displays. Olympus is known for great camera scene modes. Coincidence? No way. Your first step in taking great pictures of fireworks is to simply select the Fireworks Scene Mode. The camera will then slow the shutter speed value and set the focusing point to infinity (∞).
If your camera doesn?t have scene modes (i.e. the E-1, E-3 & E-5) or is able to support a high-level of manual control, set the camera to manual mode (M) and adjust the shutter speed and aperture. Setting the aperture to F8 and a shutter speed of 3 to 4 seconds should give good results. Set the ISO sensitivity to 100 or 80. And don’t forget to change to MF (manual focus) and set the focusing point to infinity (∞).
