1. Do you work in the sign industry?
Short answer: No. Long answer: No.
2. Where can I get more information
about a sign?
Try the references at the bottom of each
page, pertaining to a particular sign. The following
publications can be found at the following locations.
You may also find more information by
using the Picture
Australia database.
3. How can I contact you?
You can contact me via the A.D.
Online Contact Form. Please check the remainder of
the FAQ's first...
4. How do you photograph the signs
at night?
This is very challenging! You will need
to use a tripod when composing your images, because an
exposure of between one-twentieth of a second to 2
seconds may be required. In photographic terms, that is
a very long time and if you use your hands, you
will be guaranteed to get a blurred image. You need to
use 'trial-and-error' to get the correct exposure time,
and practice will give you a good 'feel' for it. You
will need to take into account the brightness of the
sign and other sources of light in the vicinity.
5. I am writing an assignment on
neon signs. Can you help me?
All the information you require is on
this website. If you wish to contact me, please use the A.D.
Online Contact Form. I cannot help with assignment writing.
6. May I use a high-resolution copy
of one of your images in my publication?
Adam Dimech's photos are licenced via his photo sales website, Photologium.com. You will need to make an application to use any of the images contained within this website for publication or use on other websites in keeping with the Copyright Policy.
7. Whom should I contact about
having a neon sign manufactured?
A sign manufacturer! These are listed in the Telstra
Yellow Pages. I cannot offer any further information about manufacturers.
8. How are neon signs manufactured?
Neon signs are formed from glass tubes
that are heated over a flame to bend them into the
desired shape. The glass is rotated and rocked in burner
flames, which use a gas and air mixture to raise the
flame temperature, which softens the glass.
The tubes are capped off with glass electrodes at each
end. The electrodes have wire passing from outside to
inside to provide an electrical current.
Before the tubing is totally sealed, an ultra high
vacuum pump pulls the air out of the tube while a high
voltage and high amperage transformer bombards and heats
the remaining air to produce temperatures in excess of
260°C. When a very high vacuum is reached and the tube
begins to cool, a small amount of inert gas (neon or
argon) is introduced prior to the sealing of the tube.
When the sign is switched on, electrical currents then
bombard the inert gas atoms inside the tube, which
displaces the inert gas’ electrons from their orbits.
As the electrons are drawn back to the nucleus of the
atom, they emit light which provides the illumination
that you can see.
The two most common gases used are neon that emits a
glowing red, and a mixture of argon and low
concentrations of mercury which emit a blue colour.
Clear glass allows one to see the characteristic colours
emitted by the gas however fluorescent powders are
usually baked to the inside walls of the glass tubing to
create a multitude of other colours. Coloured glass
tubing can also effect the colour produced.
9. My favourite sign is not
included! Why?
Well, that doesn't sound correct! But if
you feel I have missed a heritage neon sign of cultural
significance in Melbourne, please let me know via the A.D.
