Setting sensitivity query

Posted: 01-23-2007, 02:55 PM
I have two cameras, a Fuji4900Z and a pocket Fuji F11. In the case of the
F11 I can set the sensitivity to auto but in the 4900Z I have to set it to a
figure.
The top figure is 800 but I compromised in setting it to 400.
Is that a reasonable setting for a camera user who likes to have most
settings automatic? Also what would the disadvantages be if I set it to 800>

There is really no definite answer to this question.

Three variables are involved in taking a photo:
1: Sensitivity setting (ISO): the higher the number, the higher the noise,
but will capture a pic in low light
2: Aperture: High number (low aperture) needs more light but you get higher
depth of field so most objects in the photo will be in focus
3: Shutter Speed: High speed is needed to capture moving objects, but the
higher the speed, the more light you need.

I don't know the cameras you have but in general 800 is too noisy and to be
avoided, 400 "may be usable" but not great, but better than no picture. 200
should be quite good and 100 is great.
So when you have plenty of light, select the lowest ISO but with low light
bump it to 400 and hope for the best.
Also, a lot of software available to remove noise from high ISO files if you
want to play with this.

You may want to consult with a Fuji forum here and see what owners may tell
you.
