Hi all- I'm a wedding photographer and have been shooting weddings for about four years now. Recently I received an email with a request to be a second shooter during my upcoming weddings/engagement sessions and I have no idea how to respond to it. Not only are we heading into the off-season for my demographic as far as weddings are concerned, the weddings I do have booked are already contracted and I cannot pay this person for their services, as a second shooter was not part of the contract with my client. I did some research via their website and social media handles, and found that this person in question has very limited (a rather low-quality) work and has never shot weddings or engagements before, and doesn't have much experience with any other photography as well. They have not asked to be paid, they just want to "tag along" and learn from a professional. I'm incredibly flattered by their request but unsure how to respond. I don't want to make my clients uncomfortable, but I also do not want this person representing me and my brand (as a second shooter's work typically would). I also don't want photos of my client's sessions and weddings shot by this individual to end up on this person's website and thus lead to confusion. Any suggestions??
