View Full Version : SD450 Flash is to bright!

I just purchased the SD450 and have noticed that in close up pictures (two to three feet away ) taken in Low light or dark rooms the flash washes out parts of the object I am photographing.
This problem gets worse the darker the environment is.. in a completely Dark situation the object is pretty much unrecognizable with a big white spot in the center of the picture.
Is there a setting to adjust the flash? or something I can do to prevent this??

Enter the Manual mode. Then lower the ISO(sensor sensitivity) until you get an acceptable image. If you're already at ISO 50 and the subject is still overburnt, try reducing at the Exposure Compensation.

Thanks so much adas!.. I had the ISo setting at 400 *Blush*.. Is the iso setting to eliminate noise and get more detail in objects photographed from a distance? I'm sorry I know very little about camera's..

The noise is a side effect when upping the ISO.
Iso is very similar to the Volume knob on a walkman. If the music on the cassette is poorly recorded, we must turn the volume on, to be able to hear anything. But this way, the background noise of the tape gets amplified too until it become audible, so we'll hear noisy music. On a well recorded cassette, the volume control will stay low, as the music is enough powerful to be heared, and the noise will be also imperceptible.
(I took the example of the cassette, as there is far more noise than on the CD or MP3 players. Another good example would be the crappy AM radio. Hooooooh!)
And no, you won't get more detail by changing ISO. Moving a step higher on ISO scale will halving the required shutter time of the previous ISO, thus allowing for less motion blured pics.
So, as a conclusion, ISO is a compromise between shutter speed and noise.

Wow..Good explination.. Thanks so much for your time I realy appreciate it :) I guess a good setting for everyday use would be 50 then ....
