Background Information about Gordo's weather photo pages


Subject matter
All the images on this website (so far) were taken by myself.
I am interested in weather, clouds, sunsets, landscapes (and flowers).
I live in Cape Town SA, one of the most scenic cities in the world.
I am also lucky to have panoramic views (all sides, except due West).
The majority of the photos were taken from my flat over the last 10 years.

Viewing tips
If these photos look "really" bad try the following:
  • Adjust the brightness of your monitor.
  • Check that you are in a video mode that has more than 256 colours.
    (If you can't do this, you won't appreciate these images).
  • Upgrade your browser (theyr'e "free" these days).
  • Add RAM to your video card.
  • Upgrade your video card.
  • Check your Gamma setting.
  • Upgrade your PC.
  • Don't ask me for Gif's (see below).

    Camera Equipment
    All the photos on this site were taken with a Pentax K1000 camera,
    and most with an Elicar 35-200mm zoom lens (no longer in stock).
    My camera and lenses were stolen in July 1997, so I bought another K1000 (it works for me).
    For most of the latest images I used my brother's 80-200mm zoom lens.

    Computer Equipment
    Pentium 200MMx, 64Meg RAM, ATI 3D video card and Viewsonic 15in monitor.
    The Gamma setting on my monitor is 1.20.
    600/1200dpi, SCSI, 30-bit scanner
    USR Sportster 33.6 modem
    JASC Paint Shop Pro 4.14
    Win 95 (OSR2) and IE4.01

    Image capture
    Scanned from 4x6in (10x15cm) colour prints at 200dpi.
    (slides give better quality, but I don't have many...)
    Images of 1200x800 saved for archiving.
    Cropped to 800x600 or whatever seems appropriate.
    Some of the images are cropped to "non-standard" sizes to optimse storage/bandwidth.

    Jpeg compression
    I use a wide variety of "compression", from 15x, 25x, 35x, 50x to 65x.
    You probably can't print from my images, but they work well as backgound/wallpaper.
    The "compressibility" of an image seems to depend on the amount of "detail":
    - blue skies and snow can easily compress 100x, but grass, leaves and rocks don't compress more than 15x
    Until AI progresses, the only way to check, is to try all ranges on each image.
    When the image starts to look bad, then go up one step.
    (yes this is time consuming, but there are size/quality tradeoffs).
    Actually there is one shortcut:
    there is a strong correlation between the detail and the number of "colours".

    Gifs
    Never use them unless you have "line art", or you are aiming at platforms that only support 256 colours
    See what the Bandwidth Conservation Society have to say about Gif's.
    If your browser doesn't support Jpeg, please join the 1990's.
    If your PC supports 256 colours or less, you've come to the wrong site.

    Site Layout
    I am still experimenting with page layout and site naviagtion.
    At this stage this is purely a hobby - I have no major plans (yet).
    If there are any images that you really like, and wish to obtain further copies, please contact me.

    Web pages
    Notepad.Exe...
    HTML 2.x (no frames, no tables)

    Web space
    UUNet Internet Africa provide 5 Meg of personal space.
    This site is an example of what you can do with careful usage.
