One thing I’ve noticed since I started my business is that many of my clients are influenced stylistically by places they’ve lived and traveled. In today’s day and age of easy-to-use digital cameras, people capture the world digitally all the time, and using one’s own photography as artwork is close to the heart and easy on the wallet.
Hang pictures you like that have a theme like architecture, landscapes, nightlife, nature, monuments, etc. If you pick a theme for your photo gallery, it will feel thought out and complete.
Create a unified look by framing and matting the pictures all the same way. If you don’t want to stick to a theme as in the first bullet, you can always bring your photos together by presenting them in the same manner.
Finally, if you want more of mixed feel to the entire project, choose unique frames, in different sizes and just frame the images you absolutely love. When you are ready to hang them, use an old newspaper to cut the sizes you are going to hang and play around with the layout on the walls. This will save your walls from many, many holes! In this option, the final arrangement is what makes the collection look cohesive, so make sure to spend time on the layout.
Good luck with the framing and happy travels!
