Two months I posted the report "Adding a CPU Chip to a Nikon-Mount Voigtländer 125mm f/2.5 Lens", using a "Dandelion" CPU.

After posting the report, I spent some time actually using the lens, and could not get a consistent exposure. I thought that perhaps the aperture was not linear (that is, when the camera moved the aperture arm half way, the aperture closed something other than half way), so I re-programmed the chip so that it told the camera about the focal length and maximum aperture, leaving the actual control of the aperture back on the lens, as it was [...]

(The photos on this post, from my first visit earlier today to the small but elegant Koumyou-in Temple (光明院) in eastern Kyoto, have nothing to do with the prose of the post. They're just pretty pictures.)

The Problem

Historically in Lightroom, when uploading one's photos to an online service such as Facebook, Flickr, etc., one sees a little progress bar in the upper left that chunks along with each picture, such as the one shown at right. With my plugins, the progress bar makes two steps for each image, one after Lightroom has rendered the copy to be uploaded, [...]

Why is it that no matter what kind of special lens-cleaning this or expensive micro-fibre that that I buy, the most lint-free and absorbent cloth for cleaning my lenses remains my T-shirt?

You may have noticed that the images were a bit smaller in my previous post about Fumie's pointe shoes, compared to the sizes I normally use (such as in the post before that, full of, uncharacteristically, shots of me).

For years, I've followed a basic pattern on my blog for landscape-orientation photos -- those wider than tall -- giving them a basic width of 690 pixels, but yesterday's were a bit smaller at 600 pixels wide. For portrait-oriented images -- those taller than wide -- I have traditionally gone with 700 pixels tall, but yesterday limited it to 500 pixels [...]

Back during the Lightroom 2 days (circa early 2009), I spent some intense weeks writing a really great plugin, allowing a user to create custom image metadata fields on the fly. If a user suddenly decides that he wants an extra metadata field to describe the weather for a shot, or the flash setup, or a model's name, or whatever, just a few clicks in a plugin dialog and voilà, it would appear with the standard image metadata alongside each photo. I really wanted this for my own use, and I knew lots of folks would be jazzed about it [...]
