That's an easy enough shot to cut out the sign and drop in your own background. I agree...way too much noise.

Help!!!! What am I doing wrong, why am I getting so much noise?

Canon T1i, 18-55mm lens

I'm doing no sharpening, no noise reduction.

I'm importing the files, open in Bridge, move to Camera Raw, open in Photoshop, reduce size and save to jpg with quality 12
Sad

Could a bad Polarizing filer cause this?

Somewhere in your workflow you have settings or are making adjustments that are causing the problems. Recheck all of your settings from start to finish and you'll probably find something is cranked up too high.

Ok so let me ask.

Is the noise in #1, #2 or both

#1

#2

So are we seeing noise in these 2??

If you look at the Sign image enlarged, at the lower left there are "boxes" of darker blue . . . . for me, this looks like a compression discoloration. So, shoot in Raw, check you Camera Raw Settings so when you open in Photoshop you open a PSD file, work it, when saving in jpeg use 12. . . . . . . basically what PaulieWalnuts said above.

I have noticed that using a polarizer to get a bright blue sky often seems to cause noise. I don't know why, I think it's like the blue pixels in the sensor gets overload.... Maybe the bright blue sky contains no red or green information and that messes the bayer interpolation. Or something like that...

You mentioned that you reduce image size. Maybe this could be a problem - reducing logarithm in PS ( you use the wrong one?)

The only difference between this one and the first one is a wb adjustment in Camera Raw.

much better . . . . congratulations.

On an image like this you want to create an "Edge Mask" so you can sharpen only the edges and not the sky.

Thanks Etah, I'm assuming I can do a search for an "Edge Mask" tutorial and figure out exactly what you mean.

Or you can make the sign pop a bit from the image, like this (if you see banding is because it's saved with high compression):

Ok, so can you tell me how you did that.

Well it's a set of actions put together by me and they do many things. However, you can play around with layer masks and gradients and do something almost similar.
Try for example adding a new transparent layer, set blending mode to "soft light" or "overlay", and drag a black-transparent gradient over a part of it where the sky is, see the effect. You can start from there
