Photography timeline

I'm not doing any 'getting ready' photos, but I am having photos taken of me and my girls with our matching pjs on after hair and makeup are done. I personally don't see a point in photos of you actually getting that stuff done because those aren't photos you'll gift to anyone or print out in bulk. I do suggest sticking with getting family photos done though, but that's if you have any done that weren't taken before the ceremony!

****% the reception photos. Those are the only photos that actually include your guests.

I would prioritize some celebration photos over getting ready photos. Getting ready photos are generally always somewhat staged anyway (at least a little bit) and I would prefer candid photos that more authentically capture the day and include some of my guests and the special moments after the ceremony (first dance, cake cutting, etc).

One thing to keep in mind is that your photographer may be steering you more towards this timeline because they are more comfortable shooting in natural daylight and not as competent taking photos in low light settings or using flash to supplement nighttime shots. I'd review your photographers portfolio to get a sense of whether they do a lot of evening and nighttime photography. If not, it is worth thinking about how good a job they will be able to do to capture the images you really want and whether or not they are a good fit for the event you have planned. Some photographers specifically bill themselves as "natural light" photographers and they would naturally be more limited in what they could capture during evening hours depending on your setting, available light, etc. Mastering flash photography is completely different from mastering available light photography.
