Digital Photography Tutorial Explains Just How Much Digital Cameras Can Do Now

Daily we hear about new innovations in the technology field. Whether it is computers, televisions or cars, manufacturers continually come up with new and innovative ideas. There is nowhere this can be found better than with digital cameras. For many years now the American consumer has slowly switched from film cameras to digital since digital cameras produce clearer photos and provide the photographer with instant feedback as to how the picture turned out.

Today’s digital cameras are light years different from their predecessor. Not only were film cameras bulky and produced lower quality images, they were entirely dependent on chemical processing for film development. More importantly, their size made them difficult for all ages to enjoy as children often had a difficult time handling them. And, as I mentioned, the images they delivered were not as crisp and clear as what digital technology has provided. Thankfully we no longer are tied to film and bulky cameras since with digital technology the cameras are smaller and allow users to manipulate their digital images through photo editing software.

Even digital cameras have come a long way since they were first introduced onto the market. Digital cameras today are smart, instant and high-tech. Even better, they are easy enough to use that even a child can produce high quality photos. Features included on digital cameras are easy to figure out and simply by using automatic focus anyone can simply point and click to get amazing results. It is difficult to find any home still reliant on film as digital cameras are the trend of the modern times; ready to deliver all your needs, in just a few seconds.

Digital cameras work by using built-in sensors which record all the images electronically. No longer do we need to rely on film to capture our images. Photos are stored on built-in memory chips as well as portable mini-cards which can store as many as 2000 images. Once you have taken your photos you can easily transfer your pictures directly to your computer for printing or for editing. One of the greatest things is that you can delete any photo you do not like without wasting film and film processing costs.

Given all the things already mentioned you can easily understand why digital cameras are so popular. In fact, it is difficult to even find a film camera in today’s market as digital cameras are taking over the photo marketplace. They are emerging as a high quality and high performance alternatives of the traditional cameras.

It is difficult to believe that the basic components of both digital and film cameras are somewhat the same. Both cameras have a series of powerful lenses. These lenses focus the light in order to create an image of the particular object you want to shoot. The main difference between the two types of cameras is that instead of focusing light on a piece of a traditional film to capture the image, the digital camera focuses the light on a semiconductor device, which electronically records the light. A built-in computer then disperses this electronic info down into several digital data. All the interesting, fun and advanced digital cameras are the perfect results of this digital technology.

If you haven’t already purchased a digital camera for yourself you might want to answer a few of the following questions to determine which camera will suit your needs the best. Why do you need a digital camera? Will you use it to earn a living for yourself? Will you upload your photos on the Internet and earn from them? Do you need the best quality digital camera? Are you an average user of digital camera seeking fun or a serious professional photographer? Once you have figured out your requirements you will be able to determine the type of digital camera that is best for you.

What exactly is a camera sensor?

Can anyone explain how it works, comparisons, etc.

well basically, a sensor is a plate with tiny little sensors that turn light into an electric signal. that electric signal will be translated into a picture. it fills the role of film in old cameras, but no reloading required.

First, a bigger sensor means more pixels can be fitted with the same technology, provided making a bigger sensor is possible with the same pixel density, so technically the picture can have a higher resolution.

Second, to get the focal length for smaller sensors when you use normal full (large) frame lens you have to multiply it by a factor (i.e. 1.5x) to get the actual focal length (focal length basically affects the magnification). so, if u have a 50 mm prime lens (no zoom) for a 35mm(large sensor) camera, it will perform like a 75mm prime on a camera with a small sensor. (you’ll have to move farther back to get the same image, annoying in cramped places)

Full frames do have downsides though. The full frame sensor is much more expensive. The canon 5d is a LOT more than the canon 40d(smaller sensor). The lens for the EF series (full frame) are on average also more expensive compared to the EF-S series (smaller frame).

Therefore, the benefits do come with a price tag, which is why not a lot of consumers or “prosumers” go full frame.

p.s. The sensors will probably drop in price as time passes, so maybe in around 7 years full frames will be cheap enough for the average person. (lens will always be expensive)
