If your camera’s white balance is set incorrectly, or if your camera chose the wrong algorithm for measuring colour temperature, then you will observe a colour cast on your image: it will either look slightly blue, slightly orange, or slightly green. A low colour temperature shifts light toward the red; a high colour temperature shifts light toward the blue. Different light sources emit light at different colour temperatures, and thus the colour cast. Let’s take a look.
Colour temperature is effectively the warmth that is emitted from a light source, and the effect that temperature has on the intensity of any particular colour in the visible spectrum. For example, a 200 W bulb has more intensity in the orange/red end, and shows purples and blues with very little intensity. This makes your photo appear “warm”. Daylight has equivalent intensity across the whole spectrum, so you see purples and blues with the same intensity as oranges and reds. But shade or a heavily overcast sky has more intensity in the blue/purple end, so your oranges and reds will have very little intensity. This makes your photo appear “cool”.
Here are some examples of colour temperatures from common
Like film cameras digital cameras are also sensitive to movements and shakings while shooting a photo. If the digital camera moves while the shutter is open the result will be a soft or blurry photo. Usually camera movements are very small and in high shutter speeds the camera does not have an opportunity to move enough in order to distort the digital photo. However in some scenarios such as slow shutter speeds, low ambient light and macro or high zoom photos even the tiniest movement will result in a blurry digital photo.
As a general rule photos that are taken with slow shutter speeds or high zoom values should be taken using a steady platform. The best steady platform is a tripod – but when a tripod is not available (for example when you travel and you do not want to carry a bulky and heavy tripod with you) there are some other methods and alternatives that you can use as a steady platform. Here are a few:
- Lean the camera against a steady surface: you can use almost any surface that is steady in order to stabilize the digital camera. Such surfaces can
With the exception of the high-end professional digital cameras of 12 plus megapixels, the number of megapixels a digital camera is capable of generally speaking is the most important quality factor when it comes to how good your digital photos will come out. In the case of the high-end digital cameras the lenses themselves will also play a very important part.
When comparing digital cameras by the number of megapixels they are capable of, you will need to look closely at the small print on the digital camera or in the digital cameras manual. You may find that the camera is in reality capable of less megapixels then it leads you to believe.
For example some digital cameras will have in big print on the camera and or in its documentation say six megapixels, but underneath in small print it will say something like five megapixels enhanced to six using software. Basically this means that the camera is really only capable of five megapixels but the software in the camera will attempt to enhance the quality of the photos to six megapixels, this will never be as good as a true six megapixel camera.
The cost of traffic tickets and the rate of being ticketed are both rising. A big reasons for the increase in the number of traffic tickets being issued is the proliferation of red light cameras. These red light cameras are there to take pictures of the license plates of vehicles that pass through an intersection after the light has turned red. Somewhere between two weeks and two months later a ticket is mail to the offender, often with his or her picture attached. The tickets can range anywhere from $30 to over $300. The private companies that supply and operate these red light cameras share the revenues with the municipalities where the cameras are located.
We’re told that these cameras are placed at intersections for our own good, and not for the financial windfall. The fact is there has been over 1 billion dollars in traffic fines issued to date because of these red light cameras. There are even people who swear that some of the traffic lights are calibrated to increase the number of red light tickets.
There are three huge flaws in this photographic ticketing system.
First, there is the obvious one of
Looking at different digital cameras, even temperately costing digital cameras have arrangements for exposure compensation settings. To explain in a bit detail, the exposure compensation allows the users to control the amount of light entering the lens. And thereby the illumination of the photograph is decided. Exposure compensation can be altered manually or by the help of a digital camera’s exposure compensation setting that lets one override the metered exposure set inside the digital camera itself. Strictly speaking, the exposure values provide an expedient line of attack to put a figure on the available light intensity and therefore exposure.
As per general norms of the users of digital cameras, certain standards exist for selecting such values. These values are specifically known as Exposure Values (EV). Selecting an up to standard Exposure Values (EV) helps maintain the details contained in dark areas of a photo, or diminish the more than usually bright areas. Again, looking from technical point of view, the Exposure Values are numbers that refer to an assortment of combinations of apertures of lenses and shutter speed respectively. They have a selective range of values, ranging between -2 to +2 Exposure Values (EV). As a general
If you are in the market for a new camera bag, you should know that there are a lot of different options to choose from. When shopping you may have a hard time deciding which bag is just right for you. Many photographers find that they actually need two different bags: one bag for when they will be out and about and need many lenses and a smaller bag when they will just be shooting for fun and won’t need to carry as many lenses with them.
When you are shopping you need to consider how easily you can access your camera at any one time. If you are on the go and you need to be able to grab your camera with ease, you should look into a shoulder bag. A shoulder bag will give you the fast access that you need. If you don’t need to access the camera quickly and you don’t want to deal with a bag that swings to and fro when you walk, you may want to consider a backpack.
A backpack is a great option because it is on your back, will protect and transport, but will not get
Capturing the moment
Photography is about freezing a moment in time. You must make the most of the time that you have whilst you are out taking photos. If the weather is not right, use the time to explore the area, assess good viewpoints and work out what time of day will work best for the shot. Using a compass is invaluable in determining where the sun sets or rises, but remember that this changes with the seasons. Preparation and planning will help you to capture a successful photograph.
Keeping it simple and not cluttering the shot with too many elements is a good rule. By removing distractions from your photographs will help bring more prominence to your subject. It is also important to include some form of foreground interest, which may be your subject or it could be used to draw the eye towards the subject.
There is also a rule that will aid you in creating good composition, which is called the Rule Of Thirds. In photography, using this The Rule of Thirds keeps the main subject off centre, away from the middle of the frame. As a result, a photo
