If you ever feel stuck on what to learn to improve your photography game, try to explore other genres of photography. Learn about portraiture, about still life, fashion, street photography – all of those can benefit your wedding work :)
When setting up your stationary shots, take some elements from the wedding to add to your styling. Things like a few flowers and decorations can really add to your image and give it more context. If you’re feeling up for it and someone willing is nearby, maybe have them use their hand to interact a bit with the details. It can add a bit more interest to the final image.
