Forgetting about options to increase ISO and getting to basics - the slower the shutter speed, the longer light has the opportunity to reach the sensor. However, light gathering is also a function of aperture. Thus, a wide-open aperture combined with a slow shutter speed will allow the shooter to capture images in darker surroundings than a higher shutter speed and a closed-down aperture.
BUT! 1/10 sec shutter speed requires extremely steady hands (preferably a tripod) otherwise the image will likely suffer from camera shake and/or subject motion blur (unless it's a fixed object). Even a camera/lens with anti-shake won't overcome this probability..
There are tons of websites that discuss the fundamental relationship between aperture, shutter speed and ISO. Google is your friend...
In ordinary daylight there are few obvious benefits to such a slow shutter speed. The main one is in weakening light, to keep the ISO lower and reduce noise..
But in low light, either indoors or outdoors at night, slower shutter speeds are more useful. A tripod or other solid support is recommended. I often take shots at night by simply placing the camera on a flat surface such as a seat and using the self-timer to avoid shake..
Perhaps most interesting is the use together with flash. Say you are taking a picture of someone against a landscape at dusk, or indoors in a dimly-lit club. Typically the flash illuminates the person correctly, but the light cannot possibly carry and light up the background. But set a slow shutter speed and continue to use flash, the person is lit by the flash as before, and the background is now more interesting and better-exposed.Regards,Peter..
No wonder now, that my pics have so much noise (i set shutter speed to 1/200...).thanks for your quick responding.cheers..
Just got my tz5 and enjoyed it so far. playing around with it I havecome across a basic question...... what is the advantageof setting shutter speed of say 1/10 seconds instead of 1/200?thanks for any thoughts.
Don't forget a slow shutter speed had the ability to produce a flowing effect when shooting rivers, waterfalls, trees swaying, etc...
In simple terms the ideal settings should be a low iso(reduces noise), a moderate fstop(some depth of field, but the lens most importantly is at or near max quality and sharpness), and fast enough shutter speed to stop all motion(yours as well as the subject) unless blur from motion is the photographer's intent..
Some standby settings- low iso, shutter speed of 1/125 or faster, and an fstop of f5.6 or smaller(try not to go beyond f11.0 about or diffraction distorsion sets in). with the just mentioned settings you should be able to take near 90% of all your shots. unless you are trying to take shots for a special purpose or situation(macro, astronomical, racing, etc)...
