I know I’m a bit late to this reply but….as a portrait photographer I’m always being directed by the client, relatives of the client, photo enthusiast friend or relative of the client. So here is what I do.
If they have an idea I let them do it even if it’s ridiculous. After I spend 5 mins letting them getting it out of their system, I go on to do what I want. They came to you because supposedly they liked the look of your work.
Once the images are done and they are back looking at all the photos from the shoot, they inevitably like the shots I produced better [cause my ideas are better since this is what I do] but their ideas were honored, so they feel listened to as a consumer.
