Probably; but give it a viewfinder and a digiback and you could point and
shoot with it, digitally <G>

Chemical photography stuff is getting narrowed down in variety as
computers sweep all before them. We're moving towards the stage when
'traditional' photography will be a 'fine art' (like engraving, etching,
drawing, and painting, have become) with 'digital' taking over virtually
all the 'commercial', 'record', and 'souvenir' aspects.

Physics. With the very short focal lengths that go with most 'amateur'
digicams (to get sensible angles of view with the tiny image sensors),
anything much smaller than f/8 will result in the diffraction of the light
rays hitting the edge of the apperture overwhelming the un-diffracted rays
passing through the centre of the hole, thus degrading the image
unacceptably.
The curvature of the lens elements will also tend to be sharper at these
smaller focal lengths, which limits the maximum diameter you can get
without making the lenses very thick and heavy. That creates a physical
restraint to the maximum apperture possible.

That would be unusually small at that focal length. I don't think I've
seen f/32 on anything shorter than 4" or 90mm (regardless of film size).
But longer lenses can go down to f/64 or even less without diffraction
getting in the way.

They can probably follow you with a geiger counter from the ISS ;))

Using Opera, even on broadband I browse with images, scripts, Java, and
plugins, all disabled by default. I can then get only the images I'm
interested in, after the page has loaded. On dial-up that makes a big
difference to the time and expense of web browsing.

I think various 'web page templates' and 'design tools' are provided for
my Linux distro. I'll investigate, eventually. Or I'll go to gopherspace
where content rules and all there is apart from content, is the means of
finding it (and no Google!). (Lynx can get into gopherspace, but most web
browsers can't. Gopher can, of course).
