With Georgia’s U.S Senate runoff election only weeks away, it is important to make sure the process is fair for everyone. $3 from every button will now go to Fair Fight!
With six pins sold so far, we were able to make this donation to the ACLU at a very crucial time. Thank you to everyone who has purchased a button!

About RationalExpression

On Etsy since 2019

Creating things from my archive of film photos.

It started with disposable cameras. Then it was instant film. Then it was one 35mm point & shoot camera. I was hooked after that. I love the care and attention that each shot requires and the process is a labor of love. Every exposure counts. The results will manifest in the pieces that you see here.

About the name: Rational Expression was born in high school precalculus class nine years ago when I was learning about equations of the same name. It always stuck with me as being a cool name for a brand. Years later, I wanted to find a way to showcase my photos and create products based on them. I couldn’t imagine using another name.
