Maintain the life of your camera and cut the ability of the damage
Storing correctly
Moisture, excessive temperature, dirt, dust, sand and sudden impact can have detrimental effects on the life span of your camera.
Avoid sudden temperature change, otherwise internal condensation may damage your camera.
Care and Handing of Equipment
External photo storage system – hard disc drive
Copy and transfer all the data from your memory card
Online storage to backup and share your images.
Portable storage
Images that are taken with larger sensor cameras can be enlarged to greater sizes with less loss of image quality.
The better image quality is due to the fact that larger size pixels are able to gather more light and information about the quality of the light.
Digital Camera Image Sensors and Sensor Size
CMOS (Complementary Metal Oxide Semi Conductor).
Light measurements taken at the photosites in CMOS sensors are processed simultaneously rather than sequentially. Most of the processing circuitry for converting light to a charge is located at each sensor photosite so that the information doesn't have to be transported to be converted to digital information.
This makes for quicker loading and processing of the information about the light
Digital Camera Image Sensors and Sensor Size
Never force anything in your camera
Clean your camera and lens regularly:
Blow any excess dust off.
Dust and clean the inside and outside of camera with soft brush
Rub the dirt surface gently with clean damp cloth, never use liquid detergents, solvents/ water
Camera and lens Cleaning
An instrument for measuring the
intensity of light.
Help to determine the shutter and aperture settings to obtain correct exposure.
Some camera have exposure meters build in (measure only reflected light)
Measure light falling on the object (incident reading) as well as the light reflected by it ( reflected reading)
Exposure Meters

Work by blocking certain light waves from entering lens
Camera Filters/Color Filters
Allow you to fit much more info into your frame, widening your space and subject capture frame.
The compositions are altered and subject takes on new dimensions.
Wide Angle Lens
Typical - 500 mm f/8, though Sigma makes a 600 mm f/8 and there are (more expensive) 1000 mm f/11 models.
Mirror Lens
Record a smaller portion of the scene, with a long-range above 50mm, 100mm, 200mm, 300mm.
Excellent for long range action, sports, portraits and wildlife.
Telephoto Lens
When you are using digital camera:
The digital imaging sensor catches the light and carries out color interpolation in 8X8 grids
It converts the light to analogue charges
It converts the analogue charges to digital
Digital Camera Image Sensors and Sensor Size
CCD (Charge Coupled Device):
A CCD Sensor reads the amount and quality of light captured at each photosite sequentially. (one at a time) That information is then transported to additional circuitry in a different area of the sensor where it is converted to digital information.
Digital Camera Image Sensors and Sensor Size
What is Megapixel?
A megapixel (MP) is a million pixels; the term is used not only for the number of pixels in an image, but also to express the number of image sensor elements of digital cameras or the number of display elements of digital displays.
What is Megapixel?
The digital camera image sensor captures and processes information about the light that enters the camera through the camera lens. There are millions of light collecting areas on a digital camera image sensor that are called "photosites”.
These light collecting photosites are individual picture elements that are better known as "pixels". One million of these pixels are equal to one megapixel.
