Hi All,
Can anyone of you suggest me the ISO speed which I should pick to to click pictures in night with my Cannon Digital S51S camera. Also if you could tell me some other settings to make in camera which could help me to click nice shots in nights?
Thanks
at night its best to have a slow shutter speed
Answer by morgan on 09 Jan 2010 06:20:44I shoot in near total darkness at 3200ASA --- err, 3200ISO.
ASA was the OLD way to express "ISO".
The higher number is the fastest film speed. In bright sunlight on a beach, shoot at 25 ISO, at night with a flash, shoot at 300 ISO, indoor with ambient light, 1000 ISO, live theater with no flash, 1600 ISO
The higher the ISO number, the "more grain" in the image.
The S5 IS doesn't have very good ISO capability. That's because it has a small image sensor. The higher you raise the ISO, the more noise your images will have. In low light, you'll still see some noise as low as ISO 80, though.
But, for the least amount of noise...you should use the lowest ISO (80) and mount your camera on a tripod (or sit it on a stable surface) and set the self-timer for a delayed shutter release. Disable the flash. For your camera, it's the best option.
Avoid using ISO Auto or ISO High, because the camera will use a higher ISO in low light.
Set your ISO to 80 and use something like Av (aperture priority) and the camera will choose the shutter speed. Don't forget, the more you zoom in, the slower your lens becomes (the smaller the aperture is). This will require a longer exposure. You could also use P (program AE) and the camera will select the shutter speed and aperture.
Make sure you turn off the IS when you mount your camera on a tripod...
good luck
If your scene is going to be very still, it is best to use a tripod and use a long exposure. Choose the lowest ISO setting that will work with your available shutter speed. For compact Canons the limit is usually 15 seconds. Trying to compensate for low light with high ISO greatly increases noise.
Compact Canons, even those with automatic settings, usually have a manually adjustable long exposure mode. Looking at my SD 890 IS, if I hit the FUNC SET button to bring up the Function Settings, and select the exposure compensation setting, hitting the DISP button brings up a Long Shutter menu that can select from 1 to 15 seconds. Hitting the DISP button again (within the FUNC SET menu) deselects the Long Shutter, returning me to automatic with selectable exposure compensation.
When taking long exposure tripod shots, it is best to use the camera's self timer. That way when you hit the shutter release button, any vibrations that you have introduced will settle down before the shutter opens.
Even with all of the above advice, these small sensors are not great performers in very low light. Also, keep in mind that the eye has more dynamic range than a camera. In night scenes you are seeing shadow detail and shades of brightness in the lights that may look blacked out if you expose for the highlights, or washed out if you expose for the shadows. A lot of cityscapes look best if you shoot at twilight when lights are coming on but there is enough ambient light to fill the shadows. Here is a good example and explanation of that:
