Why do some photographers only make wedding dresses and not weddings?

Wedding photos and follow-up are originally two systems, and the process is different.

Wedding photo studios usually only arrange wedding photos, which is costly and large in scale. I travel a lot myself, and I won't do any follow-up work. Photographers are employed.

The wedding shooting team will generally do some business such as follow-up shooting.

The scope of the studio form will be wider, and both are acceptable. Nowadays, most of the popular overseas tours are based on this kind.
