For simplicity's sake, I would start with one camera, one lens (probably a zoom is best: 35-150 mm covers most needs) and one kind of film. If you are tempted to start with a digital camera and wish to edit and print your own images, be willing to develop your computer skills. You can have your digital files commercially printed, but you'll achieve far better control of results if you are able to work with your images on computer. Even slides or prints need to be digitised for the internet or for creative manipulation.
Finally, remember that the industry is kept alive by developing and marketing new cameras and products. You do not need to keep up with the very latest; you need a camera that produces the results you want, nothing more and nothing less. After all, photography is not all about cameras and accessories - it is primarily about the other seven chapters in this book.
Using one of my favourite systems, a 6 x 7 medium format camera and 500 mm lens.
Once you've bought the gear, there is only one thing left to do!
