I haven't been in the business of taking "events" since 1958, but I have taken some for friends and relatives. I solved the "not good photography, but cute" problem by making two packages. The second package is not shown when making up the album, but given upon delivery, as "Oh, and here are some which aren't really good enough for the job, but you might enjoy them." Even if there are only one or two in there, it is that little extra which seals the "pleasure level" for the customer. Is that cheating? Perhaps, but it works.
I recently received a note from a friend whom I haven't seen or spoken with in almost 20 years. He and his wife were going through the wedding portfolio I made for them in 1982. They wanted to comment on one of the "extras" I had included. It was a picture of his youngest son, who didn't make it back from his last trip to Iraq. Just a snap shot, but one which they now treasure.
You never know.
