How Many Megapixels?

There are several cliches in the field of megapixel-count and resolution required for acceptable photographic prints. In no particular order: 300dpi is “fine art” you don’t need as many dpi for larger prints because typically they’re viewed further away my printer claims to do 360dpi or 1440dpi or … 24 megapixels is more than enough […]

Pentax K-1: an open-source photo-processing workflow

It’s not the way I work. I prefer to make the most of […]

A bit of a hardware upgrade

He did everything – mostly sitting on the desk being a workstation, for both photo-processing and work, with added portability. And he […]

Funnily enough the need for screwdrivers has […]

A few years ago I wrote a python utility for interpolating a greater number of frames from a smaller set, for use in timelapse video/photography. Recently, I’ve been trying to learn Julia. As a small challenge – to fulfil a potential forthcoming need – and because it claimed to be quite a fast language – […]
