Back on topic, I see the pixelation you're talking about. Those are jpg compression artifacts. Check the settings on your camera. Make sure you're shooting not only at the largest size but also the best quality. I've gotten those when I accidentally shot on Large size but "basic" quality. Also check to see when you're exporting from LR and make sure you're saving the jpg at it's highest quality setting (less compression).

Check your settings. Never use auto anything, and when you think you are off auto, go in and make sure there is not a secret auto iso setting or something.
Always use 100 ISO. Noise can creep in in dark and or underexposed areas. This is stock and they are merciless about noise.
If you have LR you don't need to invest in Photoshop or Elements.
Gimp is free and can do pretty much anything Photoshop can do. However it does lack some of the expensive plugins, but you don't need them. I used to use it until a friend gave me a licenced version of CS4.

Okay, I took the camera out today and shot some nature photos at between 100-400 ISO. I think the noise is a little better this time. Maybe?
I've attached a best-I-can-do-for-now 100% crop of a recent photo. I will perfect cropping techniques in my spare time from my day job. Also, sorry I can't attach the original; I set PL to export on the highest quality, and the file is about 4 MB. :P
I know these are not particularly good photos (focus problems, I think, and white balance), but my main goal was to reduce noise.
Also, thanks for the feedback on Photoshop and noise! I am just beginning to learn more about photography, so everything I can learn is appreciated. I will take note.

Yes, you can:

What is PL? As you can see from my avatar, I'm scratching my chin trying to figure it out.
I can't see any noise (but I'm outside on a laptop so don't take my word for it) but I CAN see that it's pretty out of focus (OOF). You shot it at 1/10 second so the majority of the focus issue is probably motion. Either the camera or the leaves moved. Make sure you use a tripod and if there is ANY movement of the subject, you'll have to use a faster shutter speed than 1/10 sec.

I can tell you that there is NO-ONE, not even Perry after his medication can hand-hold a camera at 1/10 of a second!
Most people's heart rate is faster than 60/sec, so this is a limitation even if you could make yourself as steady as a rock (which few can).
Hand holding is quite simple really, one has to ensure one is using skeletal support rather than muscular.
What this means is if you tuck the elbows into the hips, better still make yourself into a tripod by sitting on the ground place the elbows onto the knees this way the forearms (skeletal support) are directly on top of the lower leg bones (skeletal support).
Lay down on the ground is even better, the only possible movement then (as the forearms are directly in contact with the ground) is any human induced side to side movement.

I think she only wanted to check for noise, she said it was out of focus.

You are right, but consider this a teaching moment :-)
To the OP it does look like you have significantly improved the noise issue, and there is no significant noise left in the image.

Absolutely Jeff, I didnt meant to be smart or anything.
Keep on teaching, by all means. I still read all posts and learn.

It was good that you reminded me I didn't respond to the OP's direct question :-)

@pharm: My bad. PL = Photoshop Lightroom. I should have just typed "Lightroom". Also, I pulled up the link to your directions. The directions say to make sure that the longest side is no more than 500 pixels, yes? So I just upload a photo to Third Light, resize so the image is no more than 500 pixels on the long size, and upload it here?
@jeffbanke: I've started using a tripod more (the two above were shot with a tripod, but probably too late at night and on a windy day). I periodically do portraits, and sometimes focus is hard for me then. Your tips will be useful.
