Last night I had the second night of Zoom meetings for ISO Photograph standards. We got stuck into the technical sessions. First up was a presentation by some people from JPEG (by which I mean ISO/IEC Joint Technical Committee 1, Subcommittee 29), mostly about the new JPEG XS streaming image file format they are developing. They explained briefly how it worked and the advantages over other streaming image compression methods. They also gave some updates on other things that JPEG are working on. I’m not particularly knowledgeable about image coding formats so didn’t get a whole lot out of it, but some parts were interesting.
Next was discussion of the revision of ISO 12233, a standard for measuring camera lens resolution. This has been being updated for nearly 3 years now, and we’re still not converging on something agreeable to all the technical experts in all countries. We ended up with the project leader deciding to give it one more go and submit a new draft for balloting, to see if we can get it finalised before the looming project deadline. If we can’t get consensus with that, we may have to cancel the project and restart it afresh.
Then we had updates on the adoption of Adobe’s DNG digital negative format as an ISO standard. That seems to be progressing slowly, as it has for a couple of years now.
And finally we had a new liaison proposal letter from the International Telecommunications Union, suggesting a formal liaison with a new group under that organisation who are proposing to standardise material related to (1) automatic white balance, (2) image metadata related to aesthetic qualities, and (3) metadata related to computational photography. This was interesting, because as the ISO committee on photography, these things very likely fall under our scope, and other organisations trying to standardise them pose a danger of proliferating/incompatible standards. And a further issue was that every single person listed on the liaison technical committee leadership was Chinese. The Chinese are known for pursuing their own standardisation goals, including existing cases where China then adopts a commercial standard that other countries don’t use, but which manufacturers in other countries suddenly need to follow if they want to continue doing business in China. So this is quite a delicate situation. It was further complicated by the US delegates pointing out that they are forbidden by the US State Department from conducting closed meetings (i.e. meetings not open to the public) with representatives of Huawei. The proposed liaison could be construed as such a meeting. So we actually have a very tricky situation to deal with. Most people at the meeting last night suggested that the best thing to do was ignore the liaison request, while others suggested a measured response to probe exactly what their intentions are and to point out that their proposals fall within ISO scope, and hint that they should back off. It’ll be interesting to watch this play out.
After the meeting ended, a few minutes late at about 02:40 this morning, I finally went to bed. I couldn’t sleep in too late this morning, as I had my face-to-face ethics class at the local school. I was extremely tired last night, but my body is still in the same time zone, so during the day today I didn’t feel too bad. Tonight at the meeting is going to be difficult though.
After ethics I had a booking for my first COVID-19 vaccination shot. It was very quick and easy, but I had to drive a few suburbs away to a clinic that was doing them. As it was lunchtime, I found a bakery afterwards to grab some lunch, which I reviewed once more for Snot Block & Roll.
This afternoon I considered taking a nap to catch up on sleep, but I’ve never been able to have naps effectively. I just can’t fall asleep during daylight hours. And I didn’t even feel all that tired, so it would have been pretty impossible. So I just relaxed and did some fun things. Let’s see how I go tonight…
