It seems to me from the quantity of posters that are going to shoot weddings that there is a very fertile market for wedding shooters. And that market includes those pros who do not have the primo gear or the primo knowledge, but that the segment seems to be half of the posters who say they shoot weddings without being geared to the hilt.
Cadillac and Chevy. A fit for everyone.
I don't feel like that comparison works. A Chevy will still get you from Point A to Point B. Heck, so will a Kia.
A lot of these 'pro' wedding photographers without the right gear are taking out of focus, underexposed, and motion blurred photos. Even taking quality and composition aside, shouldn't they still be expected to have the gear and the knowledge to at least take shots that are properly focused, acceptably sharp, and properly exposed? To me, that would be the Chevy equivalent.
When you buy a Chevy, they don't have to ask how many tires they should use, if they actually need to use a doors, what settings to use on their ignition system, or what kind of effects the gas pedal, brakes, and engine performance have on the final product. They already know the basics.
Knowing what equipment is needed, how to shoot in difficult situations, and what settings to use for those situations, is IMO, part of the basics.
We get 'photographers' here that just bought a camera, don't know how ISO/aperture/shutter speed effect photos, don't know how to use a flash, and don't even know what lesnes they need, but they are 'ready' to shoot a wedding.
If you want to stick with car comparisons, I think the more appropriate one would be a Ferrari and a Yugo.
