The only difference of the Frontier machines from the traditional ooptical minilabs is just the frontend and how the photochemical paper is exposed. The old machines uses a series of lenses to project the negative directly onto the paper. The Frontier machines scans the negative and sends the digital data to these laser scanners which writes light onto the paper, thereby exposing it.Originally Posted by student
The rest is the same.. Although the paper may be slightly different, they essentially go through the same colour developer/replenisher, bleach-fix/replenisher and several wash stages before the strip is blow dried and cut to size. It is still the very same silver-halide based photochemical process.
