I need a little help from the Photoshop Experts.

[Bogie]

I use an old version of Photoshop CS1 on Windows Vista.

When I use Bevel & Emboss to simulate cavern walls in a rock texture I get some walls that are to bright (see red circle), some that are to dark (see lime circle) and some that are just right ( blue circle ). is there an easy way to get the same type of bevel all the way around on all the exposed edges? I tried playing with the angle and altitude but could not get it the way I wanted.

What little I know about Photoshop is all by trial and error so talk slow an assume I know nothing.

Thanks
