that the choice can be a little less black and white. For example, objects that have
colors on both sides of the wheel, but are very light, can often be successfully
scanned with the Single-Color option. The closer a color gets to white the more it
starts to have in common with other colors which are also close to white, and the fact
that they’re on opposite sides of the wheel matters less. The same holds true for
colors that are very dark (close to black).

objects, go to our section on Advanced Scanning (p. ).
The Importance of Lighting
Scanning should be done in well-lit conditions. Diffuse, white light is best. The type of
light (fluorescent, LED, halogen, natural light, etc.) doesn’t matter as much, as long as
the lighting is diffused. Be aware that incandescent bulbs can add a yellowish tone to
your final scan.
Lighting situations to avoid include:
● Spotlights or shining light directly on the object – it can cause hot spots in
some areas and shadows in others making your scan appear lighter or darker
than it actually is. Also problematic when combining a scan with a heavy
shadow as colors won’t match.
● Bright direct sunlight – can overpower and wash out the scanning lasers,
leaving fewer points recorded by the scanner. Also causes hot spots.
● Dim lighting – causes missing or inaccurate data. Object will appear darker
than it actually is.
● Variable lighting – lighting that fluctuates between bright and dark during the
scan will affect the color information that is gathered, making the scan look
striped. Can also happen if light is blocked during scanning.
Some people have set up outstanding lighting rigs with light boxes or LED arrays, but
you can still get great scan results using fluorescent overhead lighting or regular
incandescent lighting.
