A thermographic or ‘infrared’ camera forms an image using infrared radiation. Infrared theory states that all objects emit a certain amount of radiation based on their temperature, called black-body radiation. In most cases, the higher an object's temperature, the more infrared radiation is emitted.
An infrared camera detects this radiation the way an ordinary camera detects and processes visible light. It works even in total darkness because the overall light level does not matter. Images from infrared cameras tend to be monochromatic because the cameras are generally designed with only a single type of sensor responding to single wavelength range of infrared radiation.
Infrared cameras can generally be divided into two types of cameras: those with cooled infrared image detectors and those with uncooled infrared image detectors.
Cooled Image Detectors are typically contained in a vacuum-sealed case and cryogenically cooled. Their sensitivity is increased because their own temperatures are much lower than the objects from which they are trying to detect radiation. Their sensors would be 'blinded' or flooded by their own radiation if they were not cooled.
Because of these ‘cool’ properties, they can provide superior image quality than uncooled infrared cameras. The drawbacks are that they are expensive to run and produce, using a lot of time and energy.
Do the research and figure what kind of infrared camera you really want to invest in if you're thinking about investing in one. There are many models out there ranging from the most basic to more deluxe models, and the technology keeps getting better. Because of infrared technology, a firefighter could go into a burning building and rescue people, target hot spots, and see through the smoke. The range of uses for infrared technology keeps growing, and infrared cameras can now be used by a company or organization, and even an individual’s home.
Uncooled infrared cameras are different than their cooler cousins because their sensors operate at room temperature. The sensors detect infrared radiation via an electrical signal that is sent back to them when they detect higher temperatures. Uncooled infrared cameras are smaller and less costly than cooled infrared cameras but their resolution and image quality tend to be lower. Uncooled infrared cameras can get noisier as they get hotter, but they can also stabilize to an operating temperature that reduces image noise
A concept that revolutionized camera technology, infrared cameras opened numerous new doors for security and intelligence operations. Once existing solely in the realm of science fiction, infrared technology has now become a standard facet of our everyday lives.

Now, it has come up with its two more brand-new digital cameras, dubbed as the FinePix AV100 and AX200. Both the cameras are adorned with the features of HD Movie Capture, Face Detection, Automatic Scene Recognition and high ISO sensitivity levels.
The brand-new 12mp cameras come built-in with a high-resolution 2.7” LCDs and boasts of proffering up to 3200 ISO settings. Both the cameras are built-in to shoot HD videos at 720p resolutions and in an aspect ratios of around 16:9.

Do NOT use Windex or any other corrosive cleaner on your lens. You will ruin the lens.
You can get lens papers or a lint-free chamois cloth from your local camera shop or photo developer. You can also get a lens cleaning solution from an eyeglasses store and a lint-free chamois cloth and use that to wipe the smudge off. Do not get a lens cloth that has a chemical solution in it.
The team here at Kirk’s Cameras understand that many of our customers are first-timers when it comes to DSLR cameras – and we would like to assist you in understanding ISO sensitivity. Be sure to look out for more of our simple, easy DSLR and Digital Camera tutorials and educational blogs!
ISO (’International Organization for Standardization’) sensitivity expresses the speed of photographic negative materials. Prior to ISO, this was expressed as ASA – standing for American Standards Association. ISO denotes how sensitive the image sensor is to the amount of light that is present at the time of photography. The higher the ISO, the more sensitive the image sensor and therefore the possibility to take pictures in low-light situations. In simple terms, ISO will help you to take images in the best lighting conditions at the best quality possible as per you settings.
In the past, ISO was a far more technical matter. Prior to digital SLR cameras, a photographer would have needed to physically change to a different roll of film if they required a different ISO speed. With the dawn of digital technology, you can simply dial the ISO straight in comfortably and easily – meaning that all of your images are on the one memory card.
The most common ISO speed settings are 100, 200, 400 and 800. Depending on your digital camera model you may also have them in the range of 64, 100, 160, 200, 400, 640, 800, 1600 and perhaps beyond. Some general tips to remember as a beginner would include:
- Use an ISO of 100 or 200 when taking photographs outside in sunny conditions.
- If the sky is overcast or it is evening time, then use an ISO within the range of 400 to 800.
- Night time or in cases of low light you might need to set your digital camera ISO to 1600.
The lower the ISO number, the slower the speed, the higher the ISO number, the faster the speed. A lower ISO will provide better image quality, however a higher ISO will capture the image you desire in low-light conditions. It is all about practice, trial and error in order to get your ISO settings perfect – we recommend you spend time getting the ISO perfect prior to taking your ideal photos. Good luck, and don’t forget to come into Kirk’s Cameras today for all of your camera needs!
