SETTINGS CAMERA

Include:

Depth of Field (DOF) Focus pull Focus throw / defocus Shutter Exposure Light background image Viewfinder Zebra strip Zooming

SET THE Depth of Field (DOF)

The DOF is influenced by the slices, and can be done manually

FOCUSING PULL

: To focus on the slide to the rear and front of the subject

Teknologi dan Rekayasa

FOCUSING THROW / DEFOCUS

Throwing focus on the slide to the back to front and at the time of the transition

between the images

Teknologi dan Rekayasa

SET THE SHUTTER

SHUTTER speed electronically regulated to set the time load CCD.  

Shutter open and close for each video frame, ie 25 times per second for PAL and 30 streams per second for NTSC

SET THE EXPOSURE

set the camera on auto-iris and the image frame is set with a good enough light.

exposure is stored in the auto function.

SET THE BACKGROUND IMAGE OF LIGHTS

Camera set on auto-iris.

Then the camera will adjust exposure for the backlight

SET THE VIEWFINDER

The viewfinder with the friction ring or slide the button on the EVF

ZEBRA STRIP SET

1. Zebra on the strip at the position2. There is a switch or menu selection labeled

"Zebra Stripes3. Select a different zebra settings (eg 75% or

100%)4. Use zebra to guide the slices

Set Zooming

1. Manual Zoom (ring): Zoom ring played manually by using the index finger and thumb of the left

2. Zoom Servo Press the front of the zoom in, press the back and zoom out.

CAMERA WORK PRINCIPLE

1. Lens

Lens captures the image, then forwarded to the panel trap shooting (CCD).

CCD-which also functions as a view-finder to send the image to the LCD.  In the DSLR camera, the image also miss the reflection mirror to reflect the image window to intip (eye finder)

2. Focal length

Image by the lens, be missed on the color filter that will be captured by CCD.

The distance between the lens and the sensor is

known with the term focal length.

Distance is also a factor that will be the multiplier

on the lens.

3. CCD

The analog function signal (the image captured by the lens) into electrical signals.

In the CCD this point there are millions of sensors, known as pixels.

The small sensor point and the more sensors, the fine and the higher resolution images produced

4. Picture

The CCD image captured forwarded to the image processor into a digital data file format images.

Images compressed according to the selected image format (RAW, JPEG).

Chipsets, software (firmware) from the camera determine the final image.

5. Image Storage

Results of the image file is sent in the selected format to the storage (storage) or memory card.

Typically, a memory card SD, CF, and so forth.

6. Printing images

Printing is done outside the camera. In the modern digital camera, still provides the

option of printing directly called PictBridge, ExifPrint and so forth.
