No, you should not tip your wedding photographer. Here’s why - professional photographers build their packages and pricing to make sure that all of their costs are covered while also making a decent profit, so tipping is unnecessary and even awkward for your photographer.
Instead of tipping, just make sure that your photographer and other vendors are included in the reception meal and that you provide them with an adequate space to take breaks and use the bathroom while they’re working for you.
Also, avoid contacting them after the wedding to see your photos earlier than the date they promised you the photos would be ready by. Sometimes, brides and grooms tip photographers hoping to have their photos done faster or to see previews. But since photographers have many clients they’re working with at one time, it’s not only uncool to put that extra pressure on them, it’s unethical to pay a higher price through the tip in the hope that your photos will be made a priority over other couples ahead of you waiting for their finished photos.
