Hello everyone. :)  I've been doing a lot of experimenting with my new Fujifilm S9500 and I've noticed that sometimes, despite good lighting conditions and whatnot, the full-sized 9 mega-pixal image has a...wierd, grainy look to it.  I'm not sure what causes this or what I can do to take better quality pictures. I'm assuming it's my own inexperience and not the camera that is a fault?

Anyway, since it's difficult to explain the problem, I've include a small sample of a photo of a rose at 100%.

Any thoughts?

If memory serves, the 9500 compensates for insufficient light by automatically increasing the ISO setting (this is to make up for not having a mechanical  'image stabilisation' or 'anti-shake' as much of the competition has).

If I am right, the grain comes from the fact that your pictures were actually taken at much higher ISO settings than you thought you were. You can check this by looking at the pictures' EXIF files and checking ISO settings.

I think Charles is right -- let us know if that does the trick! :)

Yes that sounds right unless you cropped the image or some other postwork reason

Yes, very likely that it's on auto ISO setting...and the likely culprit of the noise.

Set it to ISO 80 or 100 to see if it makes a difference.

@ Mayliah, Can you post that image with the exif attached? That looks like grain on or high compression.

Question the question. Answer the question. Question the answer...

I wish I knew what I was gonna say :oP

Thank you all. You were very correct! The camera was shooting at ISO 400...which explains all that grain! I'll have to learn to be more aware of such things in the future...
