I think that most people can tell the difference but that since the advent of Digital Photography and the overabundance of inexpensive digital cameras and over-processing, they either don't think the difference is that great or they simply don't know how to go about finding the quality they want.
Of course, there are a lot of deciding factors. In today's economy, people are trying to save money. No one wants hard feelings within the family for not letting some member of it who fancies themselves a photographer do the pictures. Many would rather have their friend do the shots because of the reasons above and not because they are the most qualified. And then there are those consumers who would rather give up quality for expedience.
I'm putting two photos up here and I would like you to comment on them. Mostly I am looking for which one you like best and the reason(s) why. The actual differences are slight to me but the impact is worlds apart. I want your opinion.
