Now it's time for the right part. Start with the dark grey top layer. Make the layers on top of this layer invisible by clicking on the eye icon in the layer palett on each layer.
This part of the camera has three layer styles:
After that you need to make an adjustment layer (curves). Ctrl-click on the layer to load its transparency and make the adjustment layer. You can use Ctrl+M if you like instead of the adjustment layer. It's just an ordinary chrome thing here but you can see my curves here
The holder has a gradient overlay and an inner shadow. The black grip underneath the holder has a pattern overlay and an inner shadow. I'm not going to show you this cause this is really easy. Just choose a pattern that you like and put an inner shadow to it. Play around because I can't show you everything.
The part where you are going to put the on and off button has two layer style; Inner shadow and color overlay. Remember that the underlying parts of the camera go beneath the overlaying parts.
This is just a simple Bevel and Emboss with no fill opacity.
These two parts have the same layer styles; Inner shadow and color overlay. Not much more to say.
What can I say? Use the Type tool. Warped text, choose arc and vertical distortion -6%. I think you can figure out the rest for yourself. :)
