Everything Digital Cameras

The history of the digital camera is quite interesting and it goes back quite a while. In fact, NASA used analog signals for a while and began changing them over to digital signals sometime during the 1960s. During this time computer use was also increasing significantly and technology for computers increased as well. The government was using digital technology at this time as well in the way of spy satellites. Soon, the private sector jumped in and helped take digital technology a long way. In the mid ’70s things started changing significantly and the road to digital cameras was paved. A machine vision camera as well as an industrial camera were introduced during this time frame as well with semi digital capacity but not exactly as we know it today. Nevertheless, digital cameras were well on their way to becoming famous.

Kodak played a big role in developing cameras and equipment that utilized digital quality or formatting in some way or another but it was not until 1991 that Kodak introduced a professional digital camera system. This digital camera was focused on photojournalists and it had a 1.3 mega pixel sensor. That was big back then but as we know today even the cheap digital cameras have more than 1.3 mega pixels!

In 1994 the first home use digital cameras were developed and marketed. They worked with a serial cable directly connected to the computer. This included the Apple QuickTake 100 camera and the Kodak DC40 as well as several others that showed up between 1995 and 1996.

Kodak really started marketing the personal digital camera and teamed up with Microsoft and Kinko’s to offer software as well as kiosks. Soon, the digital camera revolution had taken off and there were printers, cameras, and everything else that complemented the digital technology. As the years passed the digital technology increased and soon higher pixels were being offered, cameras were more affordable, and everyone was buying their very own.

Today digital cameras are super popular and it seems everyone has their very own. In fact, you can go buy a digital camera for a hundred dollars or a very nice one for a several hundred dollars. If you don’t have a lot of money then you can even buy one used for as little as $30 or $40!

When using a digital camera to take action photos you will notice that there is a delay between the time you press the shutter button to the time the camera actually takes the photo. In most cases this delay is small enough and not noticeable but when taking action photos, when trying to capture an event that just happened or when trying to capture a moving object this delay can result in a photo that just missed the action. In this article you will better understand what causes the shutter delay and how you can overcome it.

A shutter delay is defined as the time gap between pressing the shutter button to the camera actually capturing the photo. There is no shutter delay in film cameras as in these cameras the shutter button is virtually connected to the shutter itself and holding down the button results in the camera taking a photo immediately. In digital cameras the shutter button is connected to a built-in micro computer and holding down the shutter button initiates a series of events that result in capturing a photo.

When you press the shutter button the camera goes through a series of setup events in order to get all its electronics ready. Only when these events are finished can the camera capture the photo. The time it takes for the camera to complete these events can vary but is usually around one second or so. When taking subsequent photos there is an addition delay as a result of the camera compressing the photo and writing it to the slow flash memory.

Although a circa one second delay does not seem long it can make the difference between capturing an action photo to missing it. Some cameras will also initiate a focus process when the shutter button is held down and will only take the photo when the focus is completed. This can add even more delay.

Although it is impossible to remove the shutter delay in your camera there are few practices that can help avoiding its results. For example many cameras include a burst mode. In burst mode the camera shoots a fast series of photos for as long as the shutter button is held down or until the camera’s memory is full. In this mode the camera writes the photos to a temporary memory which is very fast but small. When the shutter button is released or the memory is full the camera starts the slow process of writing the photos to the flash memory.

Using the burst mode you can shoot fast photos of an action event and then choose the one that best captured the events. The speed and the amount of photos that the burst mode supports vary between cameras. Some high end cameras can take as much as ten photos over the course of one second.

Another delay that is a result of the digital camera technology is the Initial Delay. Most cameras will enter into a standby mode if not used for a certain amount of time. This time can vary but it’s usually in the few minutes range. When the camera goes into standby mode it turns off most of its electronics in order to save power. Usually pressing the shutter button will restart the camera but such a restart process is long and can take a few seconds. The result is a longer delay when taking a photo after the camera was idle for some time. In order to avoid this you would have to make sure that your camera is turned on and does not go into standby mode when taking action photos. Some cameras allow you to disable the automatic standby feature through a menu option. If your camera does not allow that you can keep it on by pressing the shutter button half way down every now and then. The downside of leaving the camera on all the time is wasting battery power. In order to maximize battery life in such scenarios you can disable the camera’s LCD screen which consumes a lot of energy and use the view finder instead.

Another way to minimize the shutter delay is to avoid the automatic focus process which usually starts when the shutter button is held down. One way to do that is to hold the shutter button half way down. In most cameras the result will be a one time focus process and then a focus lock. The camera will stay in focus and when the shutter is fully pressed it will take a photo without re-focusing. Another option is to put the camera in manual focus.

It takes practice to get to know your camera and to get a feeling of the delays it introduces. Although there is no way to completely get rid of the delays you can master overcoming them by practicing taking action photos. New high end professional cameras have a very short delay and as the electronics improve cameras will eliminate the shutter delay altogether.

If your looking for the most affordable digital camera, does that mean your looking for the cheapest camera you can find? I tend to think not. If you wanted cheap, you would have said cheap. Affordable suggests, you have some kind of budget in mind. I would assume that it’s probably a small budget, but a budget none the less. For around $150 you can get a pretty respectable digital camera. But that may be a bit high, so lets start at $150 and work our way down. You may be surprised at what we find.

In the $100 to $150 range, were able to find some very good cameras with a smidgen of the latest technology thrown in. Image stabilization and face recognition are great features to have for this price. The image quality here will be far better than anything your cell phone camera can do, and a vast improvement over disposable cameras. The Canon PowerShot A570IS would be my first choice, as well as many others judging by it’s inclusion on the best seller list on some of the big online camera retailers. The Panasonic Lumix DMC-LZ7K and several of the Kodak EasyShare models can be found in this category as well.

The $50 to $100 range is getting quite affordable for anyone, but there are sacrifices to be made in image quality and features. The Kodak EasyShare C613 still has a respectable 6.2MP and 3x zoom. A perennial best seller, and backed by one of the oldest camera manufacturers in the business. The Nikon Coolpix L11, and Canon Powershot A460 are worthy contenders to look at here as well.

Buying a decent new digital camera (that’s not a toy) for under $50 is pretty much impossible these days. Prices have dropped quite a bit, but not that low. The good news, is that if your willing to look into used cameras you can find plenty of great deals. The usual auction sites will have lots, but some of the bigger online retailers carry used cameras as well. Just make sure their return policy is good, before buying anything used.

Once you have experienced the pleasure of shooting with a good quality digital SLR camera then the likelihood is you’ll never want to take pictures with anything else. It’s not just the picture quality, but all of the things that it is possible to do with a quality digital SLR. Unlike a compact, you have an optical viewfinder rather than an LCD screen, the ability to change lenses depending on what you’re photographing and a myriad of control options.

Buying a quality digital camera is a significant investment and as with anything in life, it stands to reason that you want to protect your investments. This is where good quality camera and lens bags and cases come in. Go through a leading camera equipment retailer and you’ll soon find that there is a lot of choice out there when it comes to cases and bags.

You might want a rucksack which will allow you a high degree of mobility even if you are carrying an extensive range of kit. There are bags for beginners as well as bags for photojournalists who depend on the very best equipment in order to do their job. There is one thing that all of the products on the market have in common though, and that is the ability to protect expensive camera equipment and ensure that an SLR remains in tip top condition at all times.

The world of cameras and camera equipment can become quite technical quite quickly, so if you are new to all the terminology and are perhaps even buying your first digital camera, then make sure you go through a professional online retailer. You want a firm that has years of experience helping customers to get the right equipment that will fit their needs and their level of expertise.

There is no point buying a camera and paying for hundreds of features that never get used because the user only ever shoots on automatic. It’s always possible to upgrade as your photography improves and there is a strong market for second-hand camera equipment, so make sure that the body and lens you buy fits with your ability. And remember that one of the most important things is to ensure that your camera and lenses are protected from accidents.
