Version 2.0 - now in µLPC
I bought my present camera in January or February 1994. It was
very cheap (less than 200 kronor). I just want to take some pictures
for fun and memory, rather than waste a lot of money on expensive
equipment. This camera uses batteries for flashes, but is otherwise
purely mechanical, with a thumb wheel to advance the film. Read the
text to image 4-21 below for more details on this camera.
I number my films and images, to keep track of them. Image 4-11
(shown here) is image 11 of film 4 since I bought this camera. Each
image is scanned from the paper copy, and made available in three
different resolutions: 390x580 (JPEG only), 195x290 (both formats),
and 98x145 (GIF only). The GIF images are pre-dithered to 6x6x6 (RGB)
levels. This proved to give good results with early versions of
This WWW presentation of the photo album is automated by a µLPC
script (version 1 was an LPC4 script) in the Spinner web server
software created by Per Hedbor. Since version 1 of this photo album,
Per and I and a couple of friends have started a company called InfoVav.
To you, this µLPC script works just like a CGI script. The URL
always starts with index.lpc followed by a question mark and a
number of specifications of the form
?variable=value&variable=value. You can access the photo album
in two ways: by image and size or by specifying a keyword.
By specifying img=roll-image and
size=size, you can retrieve a single image having the
specified image identifier and size. Available sizes are l for
large, m for medium, and s for small. Medium is the
default size. For example, you can retrieve
for a large image,
for a medium sized image,
for a small image of photo 11 from roll 4.
The inline images in this page are retrieved through this script. If
you are interested, you can view the source code through your browser.
By adding type=html, you get an overview page of the sizes
and formats of that image, for example index.lpc?type=html&img=4-11.
In this case, there is no use in specifying the size.
By addressing index.lpc?key=all you get a list
of available keywords. If you click on one of them, you get an
overview page with small clickable inline versions of all images
matching the specified keyword. The magic keyword tutti is
defined for all images, xl is defined for all landscape
oriented images, and xp for all portrait oriented ones. This
means index.lpc?key=tutti is
the overview of all images inline. Early versons of some WWW browsers
had a problem displaying that page.
