The first time I tried to understand the subtleties of Layers and masks in a book about PS7, I was a bit confused. Like anyone, I understood the analogy of layers as transparent sheets used to show part of the underlying background and to be painted to replace parts of the background or add something new: like adding people on a background scene for example. On the other hand, I had practiced darkroom and was acquainted with masking techniques such as moving a cardboard with a hole in it to add more light (burn) a part of the image. Reading that book made it look awfully complicated. The Help section of Elements was and still is a quick reference guide and certainly not a step by step tutorial:

After all, there are so many edits you can do in Elements without layers that you can live happy and get excellent results ignoring them. But... you keep hearing experienced users and all pros praising the extraordinary power and magic of layers and especially adjustment layers. (See last June Newsletter).
You also hear that one of the main shortcomings of Elements is the lack of masks, and that adding them from third parties or finding a workaround is not easy.
Today, my challenge is to show you that you can achieve very quickly an interesting result with an adjustment layer... and its integrated layer mask. More important, you'll see the advantages of such a procedure.
Your mission will be to transform a flower shot by turning the background into black and white (grayscale) while leaving the flower in color.
You know how to remove the colour by using the menu Enhance/Adjust Color/Hue saturation... and moving the saturation slider left to 0. The first idea will be to duplicate the background, either by the menu Layer/duplicate or by clicking on the background layer icon in the layers palette and dragging it on the small square left icon in the palette menu bar. Then remove colour as explained above. Third, choose the eraser tool to erase the flower on the duplicate, which shows the colours beneath on the background. That works, but you'll find erasing exactly is not so easy. And if you want to save your work with both layers in the Photoshop PSD format, you'll see that the second layer makes the file size much bigger.
Now, we'll use the adjustment layer way. Use the menu Layer/New adjustment layer and choose Hue/saturation. You find the same popup window you already got under the enhancement menu. So, what is the difference?
The duplicate layer contains all the background pixels and their values. The adjustment layer only contains the settings of the adjustment. It is represented as a standard layer in the layer palette because you can toggle its visibility on/off or change its opacity just like with the duplicate. Think of it as the recording of an editing step. One big advantage is that you can examine and alter the settings afterwards, changing hue or saturation if you wish. With the duplicate layer you cannot change it: only the result is shown, and if you don't take care in recording the settings by changing the layer name, you won't recall what was done. Of course, saving with an adjustment layer does not increase noticeably the file size.
However, we cannot erase in the adjustment layer like on the duplicate. As explained above, it only contains the type of adjustment used and its settings. But in the layers palette you can see that the adjustment layer comes with a blank rectangle at the right side of the icon. It is a mask. The purpose of this mask is to tell Elements which pixels should be subject to the adjustment and which should be protected. Click in this rectangle to make it active, and paint with black to protect the pixels, the flower in our example. If you go too far, paint with white. Painting with grey will hide partially... Main advantage compared to the eraser method: no fear of mistakes, of going too far, you can always fine tune your mask afterwards. And the mask does adds very little to the file size of the PSD.
A last note: while the Help section in Elements is not a tutorial, it can help you a lot, it would be a pity to ignore it totally.
