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.
5. Flash 6. Viewing system http://www.exposureguide.com/camera-controls.htm
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
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
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.
:Visual Modification/ Manipulation using Camera
Visual Modification/Manipulation Using Camera • Editing images using camera • Adjusting the brightness • Trimming images • Correcting images • Repairing • Copy stamp
i. Editing images using camera • Select an image • Edit the image • Save the edited image
ii. Adjusting the brightness We adjust the brightness of image in the range of -100 to +100
iii. Trimming images We can trim image according to our desired range
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
