Building software for photographers

About

Hi! I'm Guillaume, a French-American software designer currently living in Tokyo. I'm a passionate film/digital photographer, and since late 2022 I've been working as Héliographe, a small independent design studio building software tools for photographers and visual artists. Our latest release is 65×24, a panoramic camera app for iPhone inspired by the classic Hasselblad XPan. Currently working on AgBr, a black and white film emulator, in collaboration with @nuevotokyo. Before that, I lived in San Francisco where I worked for over 8 years as a designer/prototyper for Apple. I was also involved with a couple tech startups as an early employee/co-founder, and my academic background is in Computer Science/Human Computer Interaction.

Apps that push you to create?

Last week, I downloaded and purchased @AgBr after seeing it on the homepage. Its design and super specific goal just immediately clicked with me. I love black & white photography, and this was a really interesting and approachable way to experiment with it; even though I've never been much of a photographer myself. I'm usually just appreciating others' photos.

But then, over this past weekend, I noticed that I kept feeling compelled to take pictures throughout my day so that I could play around with different filters and try out different levels of film grain on them. Having the tools to create was suddenly making me look for more and more opportunities to use them.
