Hue and Saturation

This piece is a bit tricky because it is very easy to over-do saturation. A small change in saturation can have a significant effect on the image. Too much of an increase in saturation can make the image look artificial.
 
 
We access the Hue and Saturation control in the same way we did our other controls - from the Layers Palette.
 

As an example, lets look at the version of the image that has had a Levels and a Curves adjustment, and add a Hue and Saturation layer.

Now we will increase saturation just a bit to make the colors a bit more vibrant...

Notice that Saturation has been pushed to just +8. That seems to be about right for this image, because there is a good deal of vibrant color here already. Of course, this is another one of those subjective calls. The highest saturation push that I use never exceeds +15, as anything higher makes the image look artificial.
 

It should be noted that saturation can be increased separately for each of the color channels, which gives much better control. It can also be increased for only parts of the image. Those techniques will be discussed in the advanced section of the tutorials. 
 

We now have an improved version of the image that is almost ready for print. The only thing left to do is remove unwanted noise (if there is any) and sharpen the image.
