jpg compression results in different file size for different scenes.

anyway, at 1024x768, don't expect great 4R prints.

yes, I know file size will varies, but what about pic resolution? how come some bigger, some smaller, when I already set resolution in setup to be 1024x728?
thanks again

JPEG compression results in different sized files, depending on the complexity of the image.

Take a picture of a blank white wall, and the compressed file will be smaller than a compressed file of a more complexed subject such as a colourful scenery.

The resolution remains unchanged.

Are you using digital zoom? I don't have an A40, but many digicams' implementation of digital zoom is simply a crop of their images.

I didn't use any didgital zoom, only optical zoom.

Again, I understand y file size change, can't understand y resolution change too, some pic big, some pic small

Are you saying that setting the camera to shoot at 1024X768, you are getting pictures of other resolutions than 1024X768?

I am curious about this issue. What kind of resolutions are you getting?

yup, I think when I zoom (optical), it will give me new resolution
