THE BULBS The picture represents the way a computer works, referring to pulses of electricity of 5V or 2V that represents the Binary notations 1 and 0. Here the lit bulb is representing the 5V and the off bulb is representing the 2V. Meaning that bulbs are 2 state devices, the same way computers are.
TAKING PHOTO Took photo from my Samsung Galaxy S2 Mob Turned Flash off, ISO 800 since I couldn’t use a tripod. White balance set to warm light. Shutter speed and Aperture was set to automatic.
PHOTO EDITING 1. Photo was rotated to 3o CCWS to make the bulbs appear straight not bended a bit to the right. 2. Cropped the part I wanted 3. Used the quick select tool to select the background 4. Refined edge => Smooth (+25), Shift Edge (+50) 5. Modified the Feather property of the selection to +3 6. After the background selection was done then I decreased the exposure (-3) and used Gaussian Blur (+3 radius) to give the bulbs (being the subject of this pic) more emphasis. 7. Finally I increased slightly the hue (+5) to remove the total amount of redness. 8. To finalise it, I added another black layer and relatively increased the canvas to 2 cm from all sides. Then I gave the picture a white stroke effect to give it an effect of having a thin frame.
BILLY THE DOG For the Multimedia topic, I emphasise with the students the amount of resources that nowadays exist that has transformed our world into a more interactive one. Through digitization, multimedia has become the norm and the least that we expect. For instance, we take it for granted when we see an edited photo or a film intro presented through graphic animation or perhaps a kitchen display through 3D modelling. Thus, the picture I edited is intended to show the students how photo editing, together with other digital resource has become a normal set up in every magazine, photo shoots, films and so on....
PHOTOS Photo of dog was taken with my old Olympus Digital Camera using the camera’s auto settings since it is very limited in manual settings available. Meaning that Flash, ISO, Shutter speed, Aperture and White Balance were automatically set.
PHOTO EDITING After following a brief tutorial on YouTube about how to resemble a 2D Photo into 3D, I succeeded in transforming an ordinary photo into a visually 3D pic.
DEDICATED MACHINES TAKING PHOTO Took photo from my Samsung Galaxy S2 Mob Turned Flash off, ISO 800 since I cannot mount a tripod with the mob. White balance set to default. Shutter speed and Aperture was set to automatic. Lit a dim white bulb from the side to have some tonality along the hand.
PHOTO EDITING 1. 2. 3. 4. 5. 6. 7. 8.
Photo was rotated to 90o CCWS to give it a better perspective Brightness & Contrast => +20 Exposure => +2 Increased the levels of black to have a purer black colour Used the quick select tool to select the background Refined edge => Smooth (+80), Shift Edge (+25) Modified the Feather property of the selection to +3 After the background selection was done then I decreased the exposure (-2) and increased the brightness & Contrast (+20) 9. To finalise it, I added another black layer and relatively increased the canvas to 2 cm from all sides. Then I gave the picture a white stroke effect to give it an effect of having a thin frame.
OUTPUT DEVICES This picture shows the output devices that are covered in the chapter about Computer Input & Output Devices. The output devices covered in this chapter include VDU (Visual Display Unit), Printers and Speakers.
PHOTO & EDITING: This photo was taken with a Canon D700 camera using automatic settings and a forced strobereturn Flash. The photo was taken in the Computer Lab at the school I work in. As part of the improvisation, I put a desk in a vertical position as a background to remove all the other distractions that may have mitigated the focus of this pic (the output devices) With Photoshop CS5.5, I cropped the part I wanted, selected the background which was then desaturate, arranged levels to enhance pure black and blurred a bit with a radius of 1px. Finally, with the spot healing tool I removed the coin lying on the desk near the printer.

THE CPU For the chapter regarding the CPU, I wanted to show the students a real transistor. I happened to have an old Motherboard that had a capsule-transistor soldered on it. This was an opportunity to take so that I can use this photo when explaining to the students that a chip or a CPU is made up of million transistors. Generally, the transistors used are printed and not manufactured while emphasising that the transistors inside chips are much smaller than the one shown.
PHOTO & EDITING The photo was taken using a Canon D700 camera with a 150mm micro lens attached to it. Several photos were taken using different settings but the one chosen has the following settings:
F-Stop: f/20 Exposure Time: 1.3 sec ISO: 100 No Flash used
Editing this photo required only few touches: I adjusted the levels, to enhance the purity of the whites. Decreased some contrast so as to decrease the vividity of the photo. I cropped the part I needed and finally increased the canvas with a 1cm as relative size all round. Painted the canvas in black and added a white stroke around the photo to create the illusion of having a thin white frame around the photo
