Heliograph
We believe a photograph should remember how a moment felt.
Heliograph is a stills camera for iPhone that develops its own photos from the RAW sensor data, the full record of the light the sensor captured, before the phone finishes the picture for you. Instead of filters, it uses real color math modeled on the photochemical printing process: a negative stage, then a print stage, so tone, color, grain, and halation come out of the process rather than being pasted on top.
Why that matters
A filter can only rearrange a picture the phone already finished. By then the phone has made its own tone and color decisions and thrown away most of the light the sensor captured, so anything pasted on sits on the surface: the same adjustment everywhere, highlights that clip to white, grain sprinkled over the image instead of living in it.
A development process answers the scene instead. Every color behaves according to how much light actually hit the sensor, so highlights roll off instead of blowing out, colors shift and cross the way film's do, and grain and halation, the glow that forms around bright lights, grow out of the bright parts of your photo, not over them. The result is not a look applied to a photo. It is the photo, developed.
The prints
Every photo can be developed with any of four prints, and changed at any time, because editing is non-destructive and the original negative is always kept.
- Heliograph, the signature print. Measured, balanced, true.
- Western Print, warm light and open country.
- Blue Steel, cool, firm, and cinematic.
- Mars, butterscotch highlights and olive greens, after the rover cameras.
