Photography + Travel

35mm, 120mm and no in between

Photography is so much fun isn't it. I love traveling around the world and photograph interesting bits. My current main drive is Fujifilm X100V and iPhone 15 Pro Max. Still figuring out the best way to showcase my works... Suggestions welcomed!

This section of the website is still under constrution...
