13 Agnieszka Piekarska & Łukasz Trzciałkowski Digital Photography Building of Digital Camera Back Viewer Power switch Preview button Menu buttons LCD Viewer

14 Agnieszka Piekarska & Łukasz Trzciałkowski Digital Photography Building of Digital Camera Specification Flash lamp - is a special lamp which illuminate places and things when we took a picture. Viewer – we can see a display frame of taking picture when we look in viewer. Self timer diode – it blink when camera is set with self timer. (Self timer afford to put camera in some place and get self-photo) Lens – it allows to zoom in and zoom out objects in photo without changing distance of it. Lens consist of lens group and lens barrel. LCD Viewer – digital screen. It is used to preview photos (by pressing Preview button) and to set the best view of photo when we took it. Menu buttons – they are used to move in menu or to scroll photos in preview. Power switch – when we switch it the lens will slide in and slide out. LCD Screen is turning on and camera is ready to took some photos.

15 Agnieszka Piekarska & Łukasz Trzciałkowski Digital Photography Building of Digital Camera Digital Camera is powered by small rechargable batery, and pictures are stored on memory card, which is built-in or is removable. Every card has different storage capacity like 16MB 32MB 64MB 128MB or even 512MB. To take one picture in 1600x1200 resolution we need about 1MB of memory, if resolution is smaller then picture waight less. e.g. to keep 32 photos on 16MB MEMORY CARD we need to set resolution in our camera like 1024x768 if resolution is set 640x480 this amount is growing to 80 photos. So we can see that if quality is small then we can do keep more photos, we need to chose… good look or amount…

16 Agnieszka Piekarska & Łukasz Trzciałkowski Digital Photography How does it work?

17 Agnieszka Piekarska & Łukasz Trzciałkowski Digital Photography How does it work? To make good picture we need to have good camera and good light, if objects which we are going to pohotograph is not illuminate enough, then picture will be in poor quality. When we have good light then we can start taking photos. So how does it realy works ? Let see… The light focused in lens is falling on a CCD (Changed-Coupled Device) Matrix which consist of milion light-sensitive cells. These cells electrify in different way depending on range of visible light.

52 Agnieszka Piekarska & Łukasz Trzciałkowski Digital Photography Advantages & Disadvantages + We can preview photo in any time we want without using special laboratories + We can use computer to correct some scratches in our photos + We can make many fotos, watch them and erase for free + We can send photos via imediately after we took it. + If we have large storage capacity memory card we can make many photos without changing a film + If its necessary we can repeat our photography -Digital Cameras are more expensive than traditional stuff (memory card, camera, bateries) -Durability of ink-jet printout is lower than traditional photos -Resolution of digital camera is still lower than traditional 35mm films.

53 Agnieszka Piekarska & Łukasz Trzciałkowski Digital Photography Future If we look in near future we can predict that digital photography dominate traditional ways of making photos.
