Would you like to capture a full frame image of a dangerous creature or a shy animal or bird. It is quite easy if you use a remote camera release. Today there are many types of remote releases available for cameras, there are cable releases, infra red or radio controlled releases. There are also many types on remote triggering devices to automatically trigger your camera as an animal or bird approaches.
Many people believe that bad weather is the time to stay at home and wish for better weather. No, bad weather is the time to get out and take pictures.
Many bad weather conditions can actually enhance your images.
When it is very cloudy, the flat lighting is excellent for photographing people or animals. The flat lighting is very flattering to the subject as the contrast is low.
Foggy and misty conditions can add a moody feeling to your images. Moody foggy lighting can be excellent for landscapes.
Here we outline the main aspects to consider in selecting and purchasing a Digital Single Lens Reflex (DSLR) camera, to help you make an informed decision on your camera purchase. The range of cameras available in any particular country may vary at any time but we endevour to give you some guidance an what to look for. DSLR cameras have larger image sensors than the compact range of cameras and will offer a far greater image quality. In addition, the range of DSLR cameras will offer a far better high ISO performance (to perform better in low light conditions) than the compact cameras.
In some digital images the noise can become quite objectionable where images are taken in relatively low light levels and high shutter speeds are required, particularly when using telephoto lenses. Generally digital cameras allow for ISO settings between ISO100 and ISO3200 even in some cases up to ISO 6400 and higher. When used at high… Continue reading Noise Reduction in Images
With the use of digital cameras we are now taking many more images than we were many years ago. What happens when you want to track down one of the many thousands of images you have taken. Will you be able to retreive the image you need.
Capturing color is all about making color predominate in the image. Colors in an image can be closely related to give the image harmony, or the colors may contrast to make the image stand out.
It is common for a splash of red in an image to make the whole image stand out. Some colors will give a warm feeling (orange and yellow), others will give a cool and calming feeling (green, blue and violet) and other may give us a hot feeling (red).
Modern digital cameras will present many option which will have a bearing on the final quality of the images and it can be very confusing to get the best quality out of the camera. Choosing Raw will give the best capture in respect to tone and color. TIFF is the next best option as with both these options there is no loss quality. Some cameras will give a choice of shooting in modes of 16, 12 or 8 bits per channel, which will influence the color depth of the image. Choosing the higher bit depth will give larger files but will also give higher quality images.
Lenses are essentially of two main categories, either fixed focal length or variable focal length or zoom lenses. Zoom lenses are available in many different focal length ranges, some popular ranges are as follows 10-20mm, 17-55mm, 70-200mm, 200-400mm.
Generally zoom lenses are available with apertures of f/2.8 or greater, however fixed focal length lenses can be available with larger apertures of f/1.4 and may be better for low or available light photography. Zoom lenses are great for landscape photography, where you may need to vary the angle of view to accommodate different aspects.
The camera Obscura is believed to be an Arabic invention in the eleventh century where a dark room with a pinhole, produced an inverted image on the far wall and this was used for observing solar eclipses. Leonardo da Vinci originally described the idea.
In 1568 Daniel Barbaro produced a box with a lens instead of a pinhole which effectively was the first camera with a lens. He also experimented with using a smaller diaphram to produce a sharper image.
Louis Jacques Mande Daguerre and Joseph Nicephore Niepce worked together and after many years Daguerre using silver plates developed a photographic process in 1839, and from that time the camera was born. For many years the camera remained a cumbersome instrument until Geoge Eastman 1854-1932 founded the Eastman Kodak Company from which roll film developed, together with many other camera developments.
The shutter speed of the camera indicates how long the shutter remains open to let the light to the film or the digital sensor.
Slower shutter speeds will give a more blurred image and faster shutter speeds will help eliminate camera shake. A good rule to reduce camera shake is to use a shutter speed faster than the focal length of the lens in use. For example with a 100mm lens use a shutter speed of 1/100 of a second or shorter.
