Emphasis can be placed on a certain subject by obscuring the foreground or background. There are three main features that can affect depth of field. Lens aperture (f-stop), distance from the camera to the subject, and the focal length of the lens (Heart 100). In order to understand depth of field one must first understand how light works. We can view objects because of light rays reflecting off their surfaces.
Turn your power supply to on position on the back of it. The user should turn on the main power button on the system on the front to boot up to the system. Personally recommend the user to follow the instructions in the motherboard manual for changing of the boot up the device, and the user needs to set up date and time on the system. The user should get to your BIOS screen on the monitor. The boot device to your system should be your DVD drive.
The lens is rotated to the correct axis (lenses with astigmatism or bifocal correction only) and the optical center (point where the prescription is strongest in the lens) and horizontal axis are marked. Step 2 Tracing the Frame or Pattern After lens checking the technician must trace the frame. Tracing determines the needed dimensions of the finished lens. There are two methods of doing this, tracing the frame and tracing the lens. The technician determines which method will work best with a particular frame based on experience and the lab's equipment.
Follow the on screen instructions. If it ask to install from CD say yes. If it ask to partition the hard drive say yes. Say yes to formatting the drive after that also and following the instructions to finish the loading of your OS.

To complete this lab we needed to have a working knowledge of the camera, developer, fix and a loop. 3.) Techniques employed: To make film of a clipart several steps must be taken. First is to turn the copy board to be parallel to the floor. Then the glass front must be unlocked and lifted.
Once you have removed the two screws the side of the case should slide right off, if it doesn’t there might be a couple more screws. Some of the newer computers have a button that you push and the side of the case slides off backwards. When the side is removed you can proceed to the next step.... ... middle of paper ... ...sk, if for some reason it doesn’t then you have to start the program manually. To do this you simply click start, my computer, and double click the cd rom drive. After the program is loaded up off the disk there will be a list of instructions that will appear on the screen in front of you.
CAMERA EXPOSURE A photographs exposure determines how light or dark an image will appear when it’s been captured by your camera. Believe it or not, this is determined by just three camera settings, APERTURE, ISO and SHUTTER SPEED (the exposure triangle). EXPOXURE TRAINGLE: APERTURE, ISO and SHUTTER SPEED Aperture: controls the area over which light can enter your camera Shutter speed: controls the duration of the exposure ISO speed: controls the sensitivity of your camera’s sensor to a given amount of light Aperture In my view aperture is where a lot of the wonderful happens in photography. What is Aperture? Aperture is a hole within a lens or Aperture is the opening
Clip the slide into place on the stage of the microscope and position it so that the letter "d" is directly over the center of the stage opening. 6. Look at the microscope from the side and use the coarse adjustment knob to lower the body tube until the low- power objective lens almost touches the slide. 7. Looking through the eyepiece use the coarse adjustment knob to raise the body tube until the specimen comes into view.
The use of a ruler would also be helpful so that accurate measurements may be taken. Method: 1. A cylindrical lens was placed on paper and traced around, a principal axis was drawn making sure that it's at rights angles to the lens. The ray box was switched on (exposing only one ray) and lined up parallel to the principle axis, a mark where the ray leaves the box was made as well as where it hits the lens (on both sides) and where the ray bisects the principle axis. After this, the ray box was removed and using a ruler, rays were accurately drawn.
