Noise, noise, noise.
Did you apply sharpening?
-
That's an easy enough shot to cut out the sign and drop in your own background. I agree...way too much noise.

Noise, noise, noise.

No, I'm doing no additional sharpening at all

is it a jpeg compression problem? are you saving the file at maximum quality?

In Photoshop I'm saving with quality 12

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
:(

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?)

How about this 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 :)

So kind of like this?

yea, that can be an example.

Thanks so much, I like that a lot. There's just so much to learn.

Hi,
In camera raw processing module in PS find section responsible for noise reduction (section 'Detail', under sharpening). There are 2 sliders - one for colour, second for luminance. As far as I remember luminance is always 0 by default, so - on 100% view - change to 30-35 and check results. In your case - you can start with colour's slider and then apply luminance, slightly less.

Luminance is set to 0, Color is set to 25 and Color detail is set to 50

... then move luminance to 35, import to PS and check results. Do you see a difference?

This one uses the tutorial and the sharpening suggestions.
What do you all think?
