Would not normally post a link to another site, although this one is an absolute winner. Has all sorts of tips for beginners to semi-pros. I would suggest scrolling to bottom and working from the end page forwards. I have to say I have read up on so many different techniques and pointers ... probably better than any book I have ever read.
I thought Id share this with you ... may help with that tough shot you have been wanting to do.
