In this tutorial, I will show you some of the awesome features found in the "Image...Adjustments" menu. Not all of the menu item will be covered, but you should walk away with a little bit more knowledge of this particular menu.
We will begin with the "Hue/Saturate" item. Fig. 1 shows that the "Hue" was moved to the left giving the image a more alien look to it.

The "Curve" is pretty cool as well. You are able to change the lighting of an image, by just tweaking it a little bit as I have done in Fig. 2. You can plainly see the difference between the 2 images.
