I am going this weekend to get my engagement pictures done. I hired a photographer just to do the engagement pictures because my wedding photographer is booked until December and is gifting us a Spring engagement session. I hired him because I needed to do our Save the Date picture and also cause I wanted Fall pictures. My question is do I tip him? And if so, what is the usual amount? I have already paid his fee and I also paid a travelling fee so I am just wondering what the correct etiquette is. Thanks!
