Day 3 of the ISO photography standards meeting began with more technical presentations and discussions. We heard information about the HEIF image file format, as well as proposals for standardising a high dynamic range (HDR) and wide colour gamut (WCG) encoding format for still images. There exist standards for HDR and WCG in video, but not for still photography yet, so we want to formalise one before manufacturers develop a multitude of competing formats.
We also had a big discussion about how to define exposure for blended images, as I mentioned was an ongoing problem yesterday. An idea raised was to categorise photos by the digital blending techniques used to produce them, so that we can then define different, meaningful exposures for the different categories. This seems to be what we’ll investigate, and some draft proposals will be put forward for the next meeting.
That next meeting is scheduled for June in New York City. My wife and I were planning to travel there, and combine it with a short holiday, but with the coronavirus still spreading we’re going to sit on that decision for a while. It’s possible the New York meeting may also be turned into a mostly virtual meeting.
Apart from the meeting, I took a couple of walks today, just to get away from sitting in front of the computer all day. And… that’s about it. It’s been a busy week – almost like being in a full-time job!

If you come to New York, I hope I’ll have the chance to buy you a coffee or something. In July I fly to your hemisphere (as you say, virus outbreak permitting) but to New Zealand, so I won’t get within about 2,000 km of you.
I’ll be mentioning it here if I do end up travelling, so you can remind me then.
