More orchids
Topic: gardening Link here

It's been a while since we've taken the dogs walking down to the “house forest”: Yvonne has deviated from decades of practice by not wanting the dogs to be together with the horses. We went today, and found, as I had expected, a number of Pterostylis flowers:

That's reassuring. There were lots of them three years ago, but in the last two years there were almost none. I wonder if there's some cycle that goes over more than one year. Either way, this looks as if they're just the first of many flowers this year.


HDR software issues
Topic: photography, technology, opinion Link here

My attempts at HDR comparisons yesterday have run into technical problems. To align the images, I first need to ensure that they're exactly the same size—even one pixel in either direction is too much for align_image_stack to digest:

Images have different sizes.
Normal-18mm-CW-3-3-0-1EV.jpeg has (3888x5184) pixel, while
Normal-18mm-CW-3-3-0+1EV.jpeg has (3888x5186) pixel.
This is not supported. Align_image_stack works only with images of the same size.

So how do I ensure they're the same size? DxO Optics “Pro” is supposed to do that, but I've probably relaxed the requirement to improve image optimization. Never mind, ImageMagick's unambiguously named convert to the rescue:

=== grog@eureka (/dev/pts/32) ~/Photos/20170725/C 212 -> convert -geometry 3888x5184 18mm-CW-3-3-0+1EV.jpeg foo

A bug in convert! Somehow things are just trying to annoy me.


HDR photos: another example
Topic: photography, technology, opinion Link here

The weather was dark and menacing when we went down to the house forest, just what we need as an example of HDR. Once again there are a number of options.

  1. Out of camera, HDR1, HDR2, 3 shot bracket, 5 shot bracket. Here's how they came out of the camera (or out of enfuse for the bracketed sequences):

    None of those look really good, but they're a starting point. The last two show both better detail in the clouds (and come closer to what it really looked like; this isn't an excessive “HDR” rendition), but they look a bit washed out. The second, HDR1, looks the worst to me: the sky is pretty much the same as the “normal” and HDR2, but the trees are much darker. I can't see any improvement at all here. And I can't see much improvement in HDR2 over the normal image.

  3. But the normal image was taken in raw format, and I can use DxO Optics “Pro” to enhance it. I can't do that with HDR1 and HDR2, because they're JPEG images (only). Now things look different:

  5. That's about as far as I want to go. The trees in the forest are very clear in the 3 shot and 5 shot sequences, less so in the “normal” shot with DxO, and almost unrecognizable in the HDR1 and HDR2 images. This is because of the use of JPEG format. Here's what DxO shows for “too bright” and “too dark” parts of the image for each of the three shots:

    The white areas between the trees show areas of underexposure, and the black areas in the sky show areas of overexposure. There's not much to choose between the three regarding highlights—HDR2 does marginally better than the other two—but the best for shadow detail is the normal image. And that's where the HDR1 and HDR2 should have been better. I stand by my viewpoint: Olympus' current in-camera HDR is useless.


Refining cailles aux raisins secs
Topic: food and drink, opinion Link here

For yesterday's anniversary, we had planned oysters and cailles aux raisins secs, quail with raisins (and not cailles aux raisins, quail with grapes). But I would have had to drive to Ballarat and find some oysters, so we ate fondue de fromage instead (and I drove to Sebastopol to buy some bread).

So today the oysters and quails were on the menu. Dammit, no oysters available, so we ate something that is claimed to be smoked ocean trout, but tasted pretty much the same as smoked salmon, and then—finally—the quails:

This is the second time we've made them, and I'm seeing room for improvement. A little bit of sweetness would go a long way.

More anniversaries
Topic: history Link here

Today's a double anniversary:

Jul 27  Greg arrives in Germany for the first time, 1967
Jul 27  Greg moves into Rosbach house, 1982

Only 15 years between the two events, but they seem a lifetime apart. And in the last 10 years it seems as if almost nothing has happened.


Tuning laksa
Topic: food and drink Link here

I've been making pre-made curry laksa for a while now, and gradually I'm changing the proportions. I'm using “MARION'S KITCHEN”, and initially I had been making 4 portions with 1.5 l of water, considerably more than intended. That's probably too much, and today I tried with only 750 ml of water for two portions. But that's too much for two, and maybe too little for three: I ended up using 695 ml for the first portion, which was really too much. 900 ml of water should do, which with 100 g fish, 25 g dofu, 85 g pok choi (a new ingredient whose place is not yet secure) should give about 1800 g of total mixture, or 600 per portion. That's what I'll aim for next time.


Baked beans again
Topic: food and drink Link here

Today breakfast was curry laksa, but tomorrow it will be bacon and eggs, and with that I need baked beans. I'm still not happy, but today I modified them slightly by using double the amount of stock powder (reducing the salt accordingly) and omitting all herbs, none of which have really proven useful. We'll see how that turns out.


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.
