Definitely "macro" if you are actually in close up when doing a close up shot.

I have also found (particularly to get clear pictures of bits of motherboard)
that
doing a long shot on the highest resolution and then cutting the picture down to
the part you want will work.  I usually put the topless Beeb, for instance,
on the
dining room table, stand on one of the chairs or even stand on the table,
and then
take a picture like that.  With all these megapixels you can quite often
still get a
decent sized image of the bit you want doing it this way.

Best wishes,


Ian

You need to set the camera focus to MACRO, often shown as a "flower in a
pot" icon. Make sure the camera is firmly mounted, e.g. a tripod.

If you have a timer feature (or even better remote control or cable release)
use that so the recoil of the button doesn't affect the image.

Use manual focus if you have it and if you have manual exposure and manual
aperture, try for a small aperture and a longer exposure. This will increase
the amount of "depth of field" - i.e. how much of the foreground AND
background that are in focus. 

A good ambient light helps a lot, preferably not from a point source but a
diffused light. Arrange the camera to eliminate any of the camera gear from
entering or influencing the shot.

Many of the pictures on your web page are very underexposed, have a look at
<http://www.q-space.com/80186.jpg> a picture of a 80186 co-processor that
was sat outside on a window sill (hence the odd lighting) this was a
non-macro, hand held shot on my trusty old Casio QV-3500EX 
and <http://www.q-space.com/laciepsu.jpg> was a hand held macro shot of a
faulty LaCie d2 PSU showing a bulging capacitor that had become closed
circuit.
