Day 2 of my ISO Standards meeting, and we got stuck into the technical sessions. Today we had a session on measuring camera resolution, another on high dynamic range and wide colour gamut (HDR/WCG) still image formats, and a final one on vocabulary and DNG (digital negative format).
The resolution one was the most technical, involving revisionary work on the existing standard to update the mathematical methods used. We had presentations of experimental results of various calculation methods, and discussion of what changes to adopt to the previously published version of the standard.
The HDR/WCG one was more administrative details of how we define these things for still images by borrowing existing details from various video standards. We had a large discussion of drafting liaison letters to other standardisation bodies. Because there are other bodies working on image and video formats, we communicate with them when we think they may be interested in what ISO is doing. This is to make sure we don’t end up with incompatible standards for things, or don’t duplicate work, and can share comments and suggestions.
Vocabulary is just listing the technical terms defined in various photography standards. The DNG project is finally getting officially kicked off, with Adobe’s imminent publication of DNG v1.6, which will be the initial basis for an ISO standardised version of this photo file format.
With the meeting done, I turned to working on some Darths & Droids writing for the afternoon. I also took Scully to the park to socialise with her doggy friends and get a walk in.
While walking, I was using eBird on my phone to record birds I spotted. Normally in this area I typically see noisy miners, rainbow lorikeets, silver gulls, pied currawongs, welcome swallows, and Australian magpies. Today I also spotted an Australian raven, an Australian white ibis, and a little black cormorant, which are not everyday birds but not uncommon. But I also spotted a crested tern, which is less common. And then when walking back from the far end of the walk I noticed a smaller brown bird, standing on a floating boom in the harbour. I had no idea what it was, but it looked a bit like a night heron in shape. A bit of searching online revealed it to be a striated heron! I’m not sure I’ve ever seen one of these birds at all before. So that was pretty cool – although it was a shame I didn’t have my SLR camera and long lens with me.
