Digital Camera Exposure
How do you take long-exposure pictures with a digital camera?
I was looking a few pictures where the photographers used a long-exposure technique – how is this performed? Is this something achievable in a point&click digital camera?
My current digital camera is the Lumix/Panasonic DMC-ZS1. I know I have some ability to adjust the exposure, it seems to be fairly minimal, unless there is another setting I am missing.
Some compact camera have a night scene mode that may give fairly long exposures. They generally do not offer exposures as long as the DSLR’s. The small sensors tend to get noisier than larger sensors at low light, long exposure.
Shopping for Digital Cameras and Digital Camera Savings
Purchasing a digital camera can be quiet an arduous task. Making choice between so many digital cameras in the market is a cumbersome process. The digital cameras today are procurable in a variety of models. A number of leading companies are bringing out several new models of digital cameras each year in the market. Amidst this cut throat competition, the customer stays in an illusion by knowing just the superficial details of these Digital Camera Options.
Remember, the companies tell you only about those features of their products, they want you to know about. A layman is not technically adept to go into the details of the digital cameras. A flashy marketing campaign is enough to allure the customers and sell the products. But you can easily get the best with in your budget by just knowing a few basic essentials for shopping a digital camera. This basic knowledge enables you to purchase the right camera, according to your choice.
The first thing to look out while shopping around for a digital camera is the number of mega pixels. You must have come across the advertisements boasting well on the more mega pixels of their digital cameras as compared to any other camera. Mega pixels are actually one million pixels. Pixels are small squares that form a picture on a camera screen. All the pixels have a particular color assigned to them. The pixels are building block of the picture.
Commonly, people presume that the larger is the number of mega pixels in a digital camera, the clearer the image is. This is a wrong notion. The pixels make a picture big or small. A 10,000 MP camera will not give you clearer image than an 8000 MP camera. But it will yield a larger image. So while purchasing the camera, be sure that you know how much pixels you want in your digital camera.
The sensors in your digital camera determine its efficiency. While you shop around for your digital camera, always pay attention to the types of sensors employed in it. Sensors are used to capture the image before transferring it to the main memory of the camera. This makes the camera ready to capture further images instantly.
Basically, you have two types of sensors. They are CCD and CMOS. The CCD is Charged Couple Device. It is found in expensive cameras. This sensor gives a great image quality. The other one i.e. Complementary Metal Oxide Semiconductor does not provide a good image quality. This sensor is mostly found in the cheaper cameras. If you are not a professional photographer, you can afford to buy some cheaper cameras with CMOS sensors.
The selection of a digital camera largely depends on the type of photography you like to do. The market is flooded with different varieties of digital cameras for various purposes. If you are inclined towards wild life photography, look for a camera with Center-Weighted metering. Center weighted metering is a feature by which the light reflected by the object is measured accurately with in the digital camera. The camera is focused at the center of the object.
If you are fond of nature photography, a wide angle lens and memory exposure lock is a must for you. Memory exposure is responsible for the depth of a photograph. The wide angle lens brings the depth visible. Always make sure that you carry a light camera if you are mountaineering or going for an adventure trip.
