Pam Hay left this morning and headed north. But first she wanted to see Lucy, the 28-year-old Paso peruano mare that Lorraine Carranza now has. Pam has known Lucy since she was a foal, and she has a colt who is a grandson of hers. So over to say hello:

I never cease to admire Lorraine's garden. It's always so tidy, and there are some interesting flowers there, like these proteas:

Taucheo fish
Topic: food and drink Link here

Yvonne and I have our differences about eating fish. She loves eating fish of any kind, while I find so much of it really boring: fish and chips, for example.

Today, being Friday, Yvonne wanted to eat fish again. What kind? After some discussion we agreed on what I call Tenggiri, but which has other names in English-speaking areas, including Wahoo and Spanish mackerel. It's a nice fish, but how do you cook it? I had this recollection from my youth of fish in a vaguely soya-like sauce with strips of onions. Took a look in “Singapore Food”, by Wendy Hutton, and to my surprise found exactly what I was looking for, titled “Fish in taucheo sauce”.

What's taucheo? A kind of soya bean preparation. What's in the fridge? Taucu, clearly the same thing. Or is it? Wikipedia has a separate page about it. I suspect that this is a regional misunderstanding, probably helped by the langauges, though the Taucheo page refers to it as 黄豆酱 and the Tauchu page refers to it as 豆醬. OK, tried it out, and how about that, exactly what I was looking for. I've seldom been so lucky. Here's my recipe.

New leveling base

House photo day today, and the first time to try out the new leveling base:

How does it compare to the Manfrotto 3416? My main concern was that it would have sufficient adjustment to remove the need to change the tripod legs. Things were a little different from what I thought. In particular, the ball is stiffer than I expected, and it grates a little when moving. On the other hand, it means that I don't need to tighten the ball when I have positioned it, so the issue is really cosmetic. It's much easier to use than the Manfrotto, and yes, it adapted to my uneven ground with adjustment to spare. Definitely an advantage over the Manfrotto.


Hugin: no control points
Topic: technology, photography, opinion Link here

To try out my new leveling head to its best, I took photos from more locations than usual, though the one in the verandah is particularly boring:

But for reasons I don't completely understand, Hugin's cpfind found no control points at all between these two images:

Why? There are plenty of similarities, and I was able to add control points manually. But cpfind decided that they were 200 pixels apart, and there was nothing I could do about it. The result was correspondingly useless:

OK, add the control points before running cpfind. No, sorry don't like those control points: I'll remove them. I tried a number of things, including the panomatic control point detector, but it just didn't want to know. In the end I took the photos again, this time ensuring that each wall was completely in one image. That worked, but only just: cpfind found only two control points between the wall and the next image to the right, compared to 21 between the two walls:

What's causing this? My best guess is that the control point detectors are looking for different kinds of features than I am, and there are none shared between these images.

I was going to report this to the Hugin development list, so I converted the (TIFF) images to lower quality JPEG images. But then the problem didn't show up! It did find some control points. Still more head-scratching to do.

One new thing I've done is to compensate for pto_gen's insistence on changing the colour balance for individual images: a simple script discolour that resets the colour factors to 1 again. Yes, it's a kludge, but it showed its worth: it proved that pto_gen wasn't the only program to reset the colour balance.


The very model of a modern stable genius

You have to say one thing for Donald Trump: he has even Yvonne interested in politics, in particular anything that can denigrate him. Today she came up with this one:

The lens is wrong, of course, but there was a flock of cockatoos intermingled with a flock (is that the word?) of ducks:

This page contains (roughly) yesterday's and today's entries. I have a horror of reverse chronological documents, so all my diary entries are chronological. This page normally contains the last two days, but if I fall behind it may contain more. You can find older entries in the archive. Note that I often update a diary entry a day or two after I write it.     Do you have a comment about something I have written? This is a diary, not a “blog”, and there is deliberately no provision for directly adding comments. But I welcome feedback and try to reply to all messages I receive. See the diary overview for more details. If you do send me a message relating to something I have written, please indicate whether you'd prefer me not to mention your name. Otherwise I'll assume that it's OK to do so.
