Blending groups

Here I have a grungy effects achieved by blending a text image on to a…photograph of Battersea Power Station.…Now I'm using the Multiply Blend mode here for this group that contains the…texture along with a couple of adjustment layers, but the point I really want…to emphasize with this is that we can get a different result when we apply…blending modes to groups than we can necessarily get when we apply blending…modes to individual layers.…Also you'll notice that there is a layer mask applied to the group rather then…to the individual layers and this is way of allowing us to mask multiple layers in one go.…

So I'm going to come now to the starting stage which is two layers one on top of…the other and one is the texture and one is the image of the Power Station.…So what I'm going to do first of all is I'm going to select this and see what we…get when we make it multiply.…Okay, well that maybe just for you after I think it's a bit too much, so I'm…going to need to make some adjustments to this.…
