A very important assignment and although it didn't actually require any pictures it was an interesting process to go through. Deciding what type of equipment you require to support your hobby as a potential business venture and how to justify the expense is not easy. There are so many things to consider, purchase or lease etc, etc.
Once you start getting into the detail it's pretty clear to see that we're not dealing with Photography in general terms, the subject itself is too vast. Once you start looking at the various types of photography work out there each one has its own specific requirements. You can't generalise and just pick a body, a few lenses and some lights. You need to seriously consider a particular field that interests you and then get an idea of the type of equipment specific to that area.
