The Science of Digital PhotographyMost digital photographers already understand digital cams and its recorded images, as well as how they work respectively. Photographers already know that cams and eyes work hand in hand with photography, since the two is what sees the color. Photographers are also aware of pixels matching paper, resolution, image sizes verses resolution, shutter speed, f-stops, exposure, and bit debts. Many people have attempted to become photographers believing all they needed to do was snap a picture and hoped it come out perfect. The fact is you need a surplus of knowledge in many areas of digital photography to get your pictures noticed. Like an artist, you will need an eye for color, contrast, and scenery itself, along with an eye for matching those pictures to please more than yourself. Traditional cams scientifically worked on images, which permitted light to go through the lenses and onto films. The films were sugar coated so to speak, i.e. they were made up of chemicals that were sensitive to light and darkness. This is the term chemical reaction coming into view, since where the film landed is when the chemicals would react. This process records the images we see once the shot is finished. Still there is more to the process; however, digital images differ slightly than traditional photo processes. Digital images are created less the film, i.e. through a array of imaging otherwise known as a chip. Two of the well-known chips include the Complimentary Metal-Oxide Semiconductor otherwise known as CMOS and the Charge-Coupled Device otherwise known as CCD. Photographers are familiar with these chips and understand how they work most times, however few will argue that once chip is better than the other. However, the cameras prove them wrong, since both chips overall deliver the same photos. The chips are obvious after a picture is taken, since you can view the photos on a memory chip, floppy drive, or the camera itself. Now, you are at the process where transferring takes place. To view your pictures, edit them, or what have you, you will need to transfer the data onto your computers hard drive. NOTE: The CMOS and CCD is essential only when you are choosing a camera to provide photos for your career or business. Digital cameras are unique in comparison to traditional cameras, since like the eyes of human sees light, so does these cameras. This is when the eye for photography comes into focus. Most photographers have a keen eye for art and views it differently than those not in the photography business views it. For example, if a person outside of photography was to see a nude picture they would probably think on the lines of pornography, however a photography will see this picture as a work of art. Its true intentions: The cameras today work like the receptors in your brain. The cameras combine three colors to achieve a light. In other words, if the camera combines red, green and blue to achieve the color white. The camera must be situated with the colors angling at a particular area of the scene to come up with this color. Respectively, if the colors are out of the cameras reach you will see the color black in your photos. To get a multi-colored picture you will need to have either low or high intensity focus. This is known as the brightness values. The color channels is what photographers refer as the value of light. Now we are at the point where the camera is recording all the colors and combing them into a full multi-color image. Go figure! A camera today is like the human brain, i.e. it functions like our receptors. by Readabout's Digital Photography Training Team |
