Once you find a photographer and a budget you can agree on, you need to meet with them to discuss a few things to make it a memorable day.
Plan on attire with solid colors. To make the images fun and different poses you both want taken.
Plan on your location and sometimes the location is meaningful with you both. Like the first place you kisses. Try to tell a story to capture your live for each other and your hobbies.
Making your engagement photos fun is easy. Many find ideas on Pinterest to see what is the trend with everyone else.
One of the most important things with engagement images is the time of day. Know when the lighting is good, morning or afternoon. Knowing will give you some amazing images to treasure.
