Creating layer masks

I really like this way of Masking an image, or of Masking just one layer. …As soon as you are in this Masking mode, you can notice that because the layer is …not blue any more, it's grey. Also, this button here is dark grey and …not bright anymore. If you want to leave the Masking mode, …just press the Q button. Then you are back in the normal mode, and …now you can see a selection, or you can switch between those two as often as you want.…

So now we have a selection, and this is easy to convert into a Layer Mask. …One possibility is to just press this little symbol here. …Or you go to the Mask windows and use this one here. …Doing this, you can see that the surface looks wonderful. …But I'm not sure if the layer underneath this layer here is in a proper position. …So, we have to move this over and make sure it's in the same position as the …water surface, but it is now. Okay, so we Masked this one.…

So we have just the water surface in one layer. …Here, you can see the underwater part of the image. …
