How to avoid post-consumption of wedding photos, or which photo studios have taken photos and know that there is no post-consumption?

Consumption is very transparent now. As long as you find a photo studio or a large photo studio with a regular scale, the later consumption is voluntary. Ask the order shop more if you don't pay in the early stage. Some people just like to add pieces and clothes later. When deciding, it is better to think about what you want and how much you plan to spend.
