Using the Scanner to take
Pictures
I have found it tedious and difficult to take pictures of models
using an ordinary camera, getting the right depth of focus and
lighting are always hard for me. The trouble is that is only when I
get the photo's back, do I realise that the results are not what I
wanted.
Thanks to friends on Origami L I discovered that a far better way
was to use my flat bed scanner. I can then see straight away if I
have got what I wanted and further I can use digital enhancing
techniques to improve the picture. The problem is when you want to
scan a 3D model, it is difficult to do this using the scanner in the
normal way. But there is a way round it.
This is the set-up that I used to take the images below.The scanner is tipped
on to its side and in front of the glass screen is a box covered in black material.
This is so arranged that it is located at the centre of the glass screen. On
this box the 3D model can be arranged at whatever angle is desired. I preferred
to be as close to the glass as possible. You can see my pureland box in position
with the lid of the scanner fully open. Since the background will not be lit
this comes out as black (or blackish) in the scanned picture. This is a great
help in selecting just the box when editing the result in a paint program. The
scan is now done in the usual way and in spite of the scanner being on its side
I have had no problems. The scan works on rails so this seems to safe enough.
The picture on the left was taken with my very old video camera and then the
moving image captured using the 'Snappy' a device which plugs into the parallel
port and contains some very clever hardware.

This is the result after a little
sharpening in my photo paint program. Compare this with the
result on right

This was taken with my
Olympus SLR camera. I have tried to get the same position
for comparison. The images here are very poor compared with
the originals no doubt due to making them as small as
possible using reduction followed by JPG. The box is my
Pureland with Mount Fujiyama on the lid.
