- Choosing the Best Camera Not a once in a lifetime purchase anymore. Select one which can do the job you want Today and as per your future requirement Some kinds of cameras do. some kinds of things better or more easily e.g., Sports photography vs. Close-up portraits. Price isnt the best indicator.
- TYPES OF CAMERAS WEB CAMERAS AND MOBILE CAMERAS
- POINT AND SHOOT CAMERAS
- ADVANCED CONSUMER MODEL
- PROSUMER DSLR models
- Professional cameras
- MEGAPIXEL MYTH How much do you need? Often, cameras are categorized by the no. of Megapixels they can capture . As if that resolution figure is the only measure of the cameras value. This value can be quite misleading.
- ZOOM: OPTICAL AND DIGITAL Optical vs. Digital Zoom An optical zoom uses the optics (lens) of the digital camera to move you closer to your subject. A digital zoom simply enlarges the existing image digitally. It is not really zoom, in the strictest definition of the term. Enlarging the image digitally reduces picture quality, and should therefore usually be avoided . Some manufacturers label their lenses with the "total zoom" by multiplying the optical with the digital. Ignore It. When comparing digital cameras: Go for higher optical zoom. Digital zoom can always be achieved later in an image editing software.
- RESOLUTION AND PRINT SIZES Resolution Avg. quality 0.5 megapixels 3x5 Best quality Resolution N/A 800 x 600 8x10 3x5 in. 1600 x 1200 11x14 5x7 in. 2300 x 1700 16x20 8x0 in. 3000 x 2000 25x40 13x17 in. 3888+ x 2592+ in. 2 megapixels in. 4 megapixels in. 6 megapixels in. 10+ megapixels in.
- PHOTOGRAPHY TECHNICALITY Anti-Blur Anti-Shake Image Stabilization Vibration Reduction A technology that stabilizes the lens to effectively reduce blur due to camera shake
- METERING How the camera measures the amount of light available to expose a picture Centre-Weighted: Readings are taken at various part of the picture, with a special emphasis for the centre. Spot: Readings are taken at a specific point. Each camera manufacturer has its own variations (Evaluative Metering)
- WHITE BALANCE The ability to adjust colours based on white as a reference colour to give as true a white as possible All other colours are corrected accordingly Auto WB (AWB): the camera determines and selects the correct colour temperature for white.
- WHITE BALANCE Some preset white balance settings are daylight, cloudy, tungsten, or fluorescent.
- Aperture, Depth of Field, Shutter Speed, ISO, Noise APERTURE a hole or an opening through which light travels It causes variations in the Depth of Field within the image
- Shutter Speed Amount of time the picture is exposed Short/Fast shutter speed Long/Slow shutter speed
- RESULTS OF VARYING SHUTTER SPEED
- ISO the measure of a digital camera sensors sensitivity to light a higher number indicates higher sensitivity This is usually expressed as a range, e.g. ISO 100 - 1600. A higher sensitivity allows us to take pictures in low light without using flash Higher ISO causes more "noise" than lower ISO
- Shutter Priority Allows you to decide the shutter speed (e.g. fast at 1/500 sec. for stop action photography, or slow at 2 sec. for night photography), and the camera decides the best aperture.
- Aperture Priority Allows you to choose the aperture (e.g. large at F1.8 for portrait, of small at F16 for landscapes).
- Manual You have complete creative control in selecting both the shutter and aperture.
- Auto All digital cameras usually have an Auto mode: the camera decides for you the best shutter speed/aperture settings.
- Landscape photography Primary function is to allow a large depth of field. Landscape mode tells the camera to default to a large Depth of Field (Small Aperture)f16.
- Portrait Photography This mode is not well suited for full-length portraits or groups of people Portrait mode tells the camera to default to a: Small Depth of Field (Large Aperture) f1.8
- Sports/Action Photography tells the camera to default its settings toward capturing images faster This is done by: Increasing Shutter Speed Increasing ISO
- Night Photography This preset slows down the shutter speed to allow a lot of light into the camera. Both the foreground and background of the image are properly exposed. very useful in taking low-light images where you do not want the background to be black
- Macro Photography This setting works with your camera lens to allow it to focus from a very short distance. Depth of Field becomes very Small (Large Aperture) f1.8 Does not have a lot of alternative uses.
- Why compose your images? Create the picture. Decide what is in and what is left out. Convince the eye to glance at it moment longer. Composition" means "Putting Together"
- Rule Of Thirds
- Rule of thirds The theory is that your photo becomes more balanced and will enable a viewer of the image to interact with it more naturally. Peoples eyes usually go to one of the intersection points most naturally rather than the centre of the shot. It works with this natural way of viewing an image rather than working against it
- Important to experiment to overcome the natural tendency to centre everything. But, sometimes you may find situations where it's difficult to follow the rule of thirds. If you know why you're doing it -feel free! But when you're first starting out it's a good idea to try to follow it whenever you can.
- Converging composition leads the viewers eye into the depth of the Photo. Usually, centre it and create a symmetrical composition leading to the centre.
- Camera lens filters still have many uses in digital photography, and should be an important part of any photographer's camera bag.... Here is the major filters and their function... 1 - Protective Filters UV Filters - Absorbs ultraviolet rays. Gives cleaner, sharper pictures with less haze. Also serves as a permanent lens protector. Personally, i have a UV filter on every lens :)
- EXIF (exchangeable image file) EXIF (exchangeable image file) data is a record of what camera settings were used to take a photograph. EXIF data stores information like camera model, exposure, aperture, ISO, what camera mode was used ..... To interpret this EXIF data, you will need an EXIF viewer. There are many ways to go about this. Your image processing program should provide that functionality within the program. For beginners, reading an images EXIF data can be a very useful learning tool....
- Night photography Take a number of shots at different shutter speed/aperture combinations. Ensure your LCD brightness is set to Normal, not Bright, for a truer representation of your recorded image. A good aperture to start with is F4.0 or F5.6 (for greatest depth of field), and adjust shutter speed up or down until you're satisfied with the shot. Always bring and use a tripod. It's quite common to have exposures of an entire second or more during night-time photography. Bring along a flashlight. A pocket flashlight is essential when you're doing photography at night.
- Minimalistic photography Minimalistic photos is creating empty spaces in the photograph.... The eye of the person looking at the image can
