Oh the grain of it

I was looking at our local newspaper. Here's the link to some of
their sports photos. They must be intentionally putting grain into
the thumbnails (and maybe the larger pictures). Some of them are even
daylight shots.

Probably camera noise from a digital camera set at very high ISO.

Looks like he's got a noisy-at-high-ISO camera but also the tool used to
create the thumbnails is making it look worse.

I don't know. Browsing more of the user submitted photos there it looks
like they're doing something horrible to the photos before putting them
up on the website.

It might be to stop the photos being downloaded and reused.

Texture screen (the digital equivalent of it), not grain.

Clearly the photographer is submitting his work to the paper via FAX.

That is my guess. This doesn't look like High ISO noise to me. It is far to
uniform. Like someone is running the Photoshop noise filter on it in
monochrome mode. It is a very good way to keep people from wanting to steal
them and with that amount of noise most noise reduction programs will just
screw the picture to remove it. They won't enlarge well. Outside of turning
thieves off the only other thing it does do is make the image files larger.
JPGs with that amount of noise isn't going to compress worth a ****.

Somebody!

I didn't check, but I wonder if that's just a case of color separation
gone bad.

It is absent in the well-lit outdoor soccer shots and most noticeable in
the lower light stuff; this suggests it is high ISO camera noise (or
different cameras were used)...

Thumbnails should be noise free due to downsizing/averaging - maybe they
were simple pixel resizes without 'smart' interpolation/averaging?
