Digital Photography? Digital photography is a form of photography that uses cameras containing arrays of electronic photodetectors to capture images focused by a lens

2. Image sensor Image sensors, whether they are CCD or CMOS, vary from camera to camera but they’re basically the same, and the megapixel count shouldn’t be a priority in the decision-making process when buying a camera. Why? Because the size of the sensor is actually more important that the number of megapixels.

3. Camera lens If you are concerned about picture quality, you should invest in a digital SLR (DSLR) camera with interchangeable lenses. Interchangeable lenses allow you to have much more control of your images, and to be far more creative than you can be with a point-and-shoot camera.

4. Camera modes Shooting mode dial: to choose the desired shooting mode.

Exposure compensation setting ISO setting You use this feature to change the ISO setting of the camera. The ISO determines how sensitive the sensor is to light. You use higher ISO settings to take pictures in low light conditions. On many cameras, a dial is used to change the ISO. Some cameras use a menu command to change the ISO setting. Aperture setting  The aperture determines how much light enters the camera. When you choose Aperture Priority as the shooting mode, you use a dial to change the aperture, and the camera automatically selects the shutter speed to properly expose the image. Shutter speed setting The shutter speed setting comes into play when you shoot in Shutter Priority mode. After choosing Shutter Priority for the shooting mode, you use a dial to change the shutter speed, and the camera automatically selects the correct f/stop to properly expose the image. Exposure compensation setting This is used to increase or decrease the exposure. You increase or decrease the exposure when the camera gets it wrong.

White balance You use this setting to set the white balance. If the camera gets confused due to multiple light sources, the whites have a color cast to them and may have a green, orange, or blue tint. You can rectify this problem by choosing a preset white balance (such as Fluorescent, Tungsten, or Shade) or by manually setting the white balance. Flash control If your camera has a built-in flash unit, you push this button to pop the flash unit up and enable it. You can use flash to light the scene or add additional light known as fill flash. Hot shoe You slide a flash unit that’s compatible with your camera into this slot. The contacts in the hot shoe communicate between the camera and flash unit. LCD panel This panel shows you all the current settings. When you change a setting such as the shutter speed or ISO setting, the panel updates to show you the new settings. If your camera doesn’t have an LCD panel, these settings are visible in most camera viewfinders.

: Techniques

RULE OF THIRD The Rule of Third is a guideline for composing images

Compose shots so that points of interest align with am imaginary grid that divides the image into thirds vertically and horizontally

Like this…….

Which looks like….

The Rule of Third is a guideline for composing images

Think about what elements of the photo are most important and try position them at or near the lines and intersection of the grid

When photographing moving objects, position them as normal, but also pay attention to direction they’re moving

Like this…….

As a general rule you should leave more space in front of them than behind, to show where they’re going

Another photography principle is the use of lines to draw the viewer's eye. "Lines can be the shape of a path, a line of trees, a fence, or any feature in an image" (Telg, 2010a, p. 2).

Different types of lines can be used to convey messages and add interest to a photograph. Diagonal lines can suggest depth or action. Vertical lines can convey power, strength, or even growth. Horizontal lines can convey stability or rest and can easily follow the rule of thirds.

Diagonal lines can add depth and perspective to any agriculture-related photograph, such as this photo of row crops in a greenhouse. When photographing livestock in their natural environment, it is important that the environment be perceived as healthy and desirable. to portray animal agriculture positively, if done incorrectly, may generate consumer misperceptions When photographing plants, keep the position of the sun in mind to reduce the tendency to capture undesirable shadows.

iv. Correcting images We are able to correct images using 2 ways: Repairing Copy stamp Repairing We can correct an image so that the unwanted spots (spots that we want to delete) on the image blend with surrounding color Copy stamp We can correct an image by pasting a section copied from another part of the same image to unwanted part of image

Media Storage Devices Types of storage devices Compact flash (CF) Secure digital (SD) Multi Media Cards (MMC) Memory stick Hard Drives One-time used flash cards

Types of storage devices 1. Compact flash (CF) Developed by SanDisk Corp About the size of matchbook Offer high storage capacities Fast processing times Suitable for video recording

Types of storage devices 2. Secure digital (SD) Smaller than CF

Types of storage devices 3. Multi Media Cards (MMC) Even smaller cards Used in a few pocket cameras

Types of storage devices 4. Memory stick By Sony Corporation Shaped like stick of gum

Types of storage devices 5. Hard Drives Example: Hitachi’s Microdrive High speed High capacity

Types of storage devices 6. One-time used flash cards Introduced with idea that flash memory is not expensive Store photos on a card instead of copying to a computer Not recommend for serious photographer
