The concept of night photography is same across the board with cameras. Since you have a SX40, you have the added benefit of manual controls. For most night or low light shots, you should consider using a tripod to prevent blurring. You might also need to use manual focus as your camera will have trouble focusing. If you have a tripod, use a low ISO setting. If you need depth of field or if you want starbursts, use a smaller aperture (big f number). Then adjust the shutter speed to your liking. Most likely your shutter speed will be greater than a second so the SX40 will force your ISO to be low anyways. You can do these in Either Tv, Av or M mode depending on what youre comfortable with. If you need more help with night photography, you can search the internet. The concepts are all the same and can be easily applied to your camera as it has manual modes. Automated scene modes tend not to do so well at night as cameras have issues with focus and metering correctly when lighting is not the best.IMAGE LINK: http://www.flickr.com …s/jfchanphoto/6639922357/ Day 4: Mary Ave Foot Bridge
You can start off by going into Av mode and set the aperture you want. If youre doing a night landscape shot, you can set your camera onto a tripod and set your camera to f8. Then press the shutter. You can also use your timer to reduce camera shake from pressing the shutter.
Indoor shots are a lil harder with point and shoots if you do not want to use the flash. Even if you use a large aperture and high iso, the images will not look good. This is one of the weaknesses of a point and shoot still.
Heres a shot I took with the SX230hs on a tripod, settings are: 15seconds, f8, iso 100, IS off, manual whitebalance.
