The pictures show a News Graphic for a new kind of Light Emitting Diod (LED) which is based on NanoWire-technology (a Swedish invention?).
Dot #1 show an ordinary LED the way they have looked for decades.
Dot #2 show a much more light intense HB- LED (high-brightness). This one was invented during the 90's and can be found in modern flashlights.
Dot #3 show a completely new type of HB-LED which use NanoWires made of ZinkOxide (see the large circle on the left). This ZnO HB-LED is extremely energy efficient and has a light which is much more aimed, compared to the older HB-LED.
The second picture
Dot #4 Older HB-LED used ThinFilm technology which in short consisted of two thin layers which, when an electric current was added, started to radiate light (fotones) in every direction.
Dot #5 The NanoWire technology is based on leading the light, the fotones, in one direction. The ZnO HB-LED may radiate approximately the same amount of fotones as a regular HB-LED, but with the aiming of fotones, you are given a much more intense light.

Material: The client provided a Word document where the process was explained. Also a number of pictures were presented, one being a photo of NanoWires as seen through an electron microscope.
Tools: FreeHand 9 to define the contours of the main image and all the LEDs. After that, the work was moved to Photoshop for colouring, surface and shadows.
