"fun" with a camera can mean lots of different things to different people.
Some people think taking a "selfie" with their iPhone is photographic fun. Others might think the very deliberate and technical aspects of working with a 4x5 view camera with full movements is photographic fun.
To a teenage girl who likes taking self portrait (aka selfie's) photos on her phone to post on Facebook, standing under a dark cloth and composing on an upside down and reversed ground glass with a loupe probably would not be very fun.
Likewise, I could not imagine the likes of Weston or Adams standing in front of a mirror in the bathroom making a a "duck face" and consider it a good time (though who knows lol)
Photographic fun is different for everyone.
Manually operating the controls of a precision instrument and shooting brick walls might be one person's idea of fun, while another person is taking photos of people from across the street with their new 24-1000mm equiv superzoom bridge camera and calling it "street shooting" and having a blast.
