The picture looks great Robert, really deep colours. I thought you still had dust on it when I first saw it, then realised it was on my screen. A quick flick with a duster and bingo. Don't you just wish all your problems were so easy. Best of luck with your photoshop learning.

Robert, Nice job getting rid of the dust spots! If the sky bothers you because it looks too hazy, try this:

1. Create a new layer on top and merge to that layer (Shift-Alt-Ctl-E).
2. With the new layer active, go to the channels palette. Highlight the red channel and Ctl-A (to select all) then Ctl-C (to copy).
3. Highlight the composite channel again, then go to the layers palette. Ctl-V and the red channel should paste in as it's own layer on the top of the layers palette.
4. Change the blending mode of the red channel layer to luminosity. This will help the sky, but make the foreground look wierd. So use a layer mask and a soft brush to "erase" the bottom part of that layer.
5. Create another new layer on top and Shift-Alt-Ctl-E to merge everything onto it. Change the blending mode to overlay and the opacity to 65%. Again, use a layer mask to erase the bottom portion of the layer.
6. Almost there, just do a simple levels correction to make the image "pop" a bit more. If the remaining "haze" is too blue, you might want to do a curves or hue/saturation adjustment to fix that.

I've attached your image with the above changes so that you can see the difference.

Have you got those instructions correct - CTRL ALT ~ selects the highlights.

I think it is SHIFT CTRL E to merge the layers to the current layer.

Smile Or try this.... fix the sky.

1) Copy the layer (Ctl_J);

2) Right click on the new layer to open blending options (or double-click);

3) Set blend mode to multiply (or screen, as you like);

4) Set blend-if to Blue (there's little blue in the foreground, so we're going to be fixing the sky only);

5) Slide the little black triangles to the right (you'll see the effect moving up the photo) until you reach the hills;

6) Alt-Click on the triangles to separate them and take the right triangle up to 255;

7) Keep adjusting (playing with) the triangles, blend mode, opacity until it's the way you want.

........Blend-if CAN be fun!

(sorry, don't think I can post an image - I'm hiding behind a thick firewall)

My favorite technique to remove Dust & Scratches is to use the Blur Tool.

Set Mode to Lighten for dark dust/artifact type spots with Opacity @ 100%, then use the Clone or Healing Tool for the few bigger spots.

Hi Robt, sorry this is a long time in coming - try my software for dust removal on this image - I did and it cleaned the image up easily! The software was designed for this very purpose and type of image!

See what you think and let me know?

working only with the original image posted, i noticed a LOT of noise in the picture. by resizing down to a smaller image it corrects almost all of this. i suspect this was a result of 'digital zoom' on the camera, which is basically nothing more than zooming in with a similar algorithm as photoshop. by resizing you get rid of that.

the next thing i did was clone out the dust in the sky and a few in a few other places. it really wasnt that much.

i then masked the sky and ran both a light median filter and a low gausian blur to even out the artifacting..

i also ran a histogram adjust to balance up the colors and brightness.

nice pic, btw
