Photocrazed ... firstly, welcome ... next, I hope the pic below helps you (my answer to your questions) ... also I would suggest you try a few of
the Keeper's tutorials (not from the point of view of 'making' something, but to watch what each step does and where to find things .. as this is how I found my way around Photoshop - and still am!! [bustagut] ) .. click on the photshop gurus logo at top of this page to go to
the Keepers site ... and finally, you have joined a very helpful forum, if you get stuck ask for more help 'cos there's heaps of it here (that's why I'm still here - need all the help I can get!!

) ....
