Digital cameras are devices that record images digitally on a light sensitive sensor. They can be used to take still photographs or videos. Highly versatile, they can take thousands of images on a single memory device, can record video with sound, edit these images and delete them allowing re-use of space. Digital cameras have been incorporated into many other devices like PDA’S mobile phones and vehicles. The Hubble Space Telescope is a digital camera.

Initially, the idea of digitizing images on scanners was used by the Jet Propulsion Laboratory to provide astronauts with navigational information. A mosaic photo sensor would record locations of planets and stars. This would help astronauts to orbit and land. The FUJI-DS-ISP 1986 was the first true digital device that recorded images in a computerized file. The first digital camera with LCD was the Casio QV-10 in 1995.The image resolution is achieved by the camera sensor that turns light into discrete signals. Millions of “buckets that make up the sensor, count the number of photons that strike it. The brightness of the image is dependant on the number of pixels (the smallest unit of information for an image).

The rapid technological improvements have dramatically reduced costs. “Pixels per dollar” has become the measurement of value of a digital camera. The camera either uses the single shot or the multi-shot method of capturing an image. This refers to the number of times the sensor is exposed to the light passing through the lens. Scanning is another method wherein the sensor moves like a desk-top scanner. In some cases, scanning is achieved by rotating the whole camera, enabling one to get images of a very high resolution. In recent years, technical improvements have made single shot and LCD based cameras very popular in commercial and digital photography.

Let us dwell on the connectivity of these new model digital cameras. Early computers used the Serial port to transfer data. There are cameras that use wireless connections via Bluetooth or IEEE 802.11 Wi-Fi.Modern cameras come equipped with Pict Bridge Standard which allows for the automatic transfer of data to a Pict Bridge capable computer printer, thereby circumventing the need for a computer.

These cameras lend themselves to a variety of uses. They allow one to view a photograph as soon as it is taken. With constant improvements in technology, and cutting-edge software available, modifications and digital manipulations seem almost endless. They are ideal for sports enthusiasts, who can capture fast action in all its glory. They are ideal for capturing loving moments of family get-togethers. Professionals and amateurs can use these cameras to freeze those special moments of life that come rarely!

I’m guessing that I’m a lot like you in that I want to take good pictures.

Not necessarily because I want to sell them, but just because I want to take better pictures when I go on vacation or when I go to parties or just when I’m going around town. I’ve done a lot of searching and have found some tips that I thought you may find handy, so I figured I’d share with you in this article.

This is by no means a definitive list, but these are the most pertinent digital photography tips about landscape photography that I’ve found most useful. Without further ado, here are 8 tips about digital photography of landscapes:

Landscape pictures:

1. The best light is early in the morning, or late afternoon just before sunset. No one ever photographs the Grand Canyon in the middle of the day for a reason. The hour just after sunset is known as the golden hour because of the golden hue of the light. Make sure you turn off the flash so you can capture all the colors. Make sure that you use a tripod to steady the camera during times of low light. A window sill, fence post or wall will do the trick in a pinch. Of course, you can take pictures at any time of day, just make sure that you play around with the effect of the natural light on your photo. So, tip #1 can be summarized as: Choose the right light.

2. Use the software on your camera. Depending on the camera, it may have a special setting just for taking digital pictures of the landscape. It’s usually called the landscape shooting mode. This camera mode usually ensures that all items both near and far are focused and color balanced. So, tip #2 can be summarized as: Use your camera’s settings properly.

3. If you want to show the magnitude of a scene, use objects that are close to the camera to show the magnitude and scale of the scene. Use something like a fence post or the branch of a tree to juxtapose in your picture.

4. Another great way to show the magnitude of a scene is to feature people in the landscape pictures. This is great for showing the majesty of the scene.

5. Place your subjects off center. Place the people or the objects in your pictures just off center to make for a more interesting shot. Some scenes are just more interesting when there’s a person in the picture.

6. Frame the shot using framing techniques to help the photo seem complete.

7. Enhance your photos using the color effects that come with your camera’s software. For instance, you can enhance the color of the sky or of the ground using the digital settings on your camera to make the scene look richer.

8. Have fun taking pictures!
