Helpful answers to some popular photographic questions.
What is the difference between digital and film photography?
The main difference between digital and film is how the information is captured and stored. With film the information is stored on light sensitive crystals on celluloid film, digital information is stored on imaging sensors.
How to deal with noise at high ISO
The best option to deal with noise is to leave the pixels untouched, using a RAW file to process the image later with software. You can also shoot JPG files and let the camera’s processor apply its noise-reducing algorithm (if your camera has that option).
What causes red eye and how to reduce it?
Red eye is caused by light from the flash hitting the back of the eye (retina) and the camera recording the reflected light at red. To reduce the effect, try bouncing the flash or angle the flash so that the light hits the eye at an oblique angle.
Avoiding Lens Flare
Lens flare can occur when a bright light source appears in or at the very edge of a photograph and is often characterized by sun spots appearing throughout the image.
To aviod this try using a lens hood also avoid direct sunlight or any strong backlight entering the lens.
What are megapixels?
Megapixels are single points in a graphic image. The more pixels used to represent an image, the better will the image look.
A camera’s megapixel rating will help you determine the largest size of prints you can expect to make without sacrificing the quality of the image.
Do more pixels mean a better quality photograph?
Not necessarily, more pixels does not mean better quality photographs. Increasing the Megapixels (resolution) of the camera merely increases the size of the photo. This means that you can make larger prints, or crop a large area without losing too much detail.
What is digital and optical zoom?
Digital zoom is not really a zoom at all; a digital zoom just enlarges a portion of the image ’simulating’ optical zoom. In other words, the camera crops a portion of the image and then enlarges it back to size.
Optical zoom uses the optics (lens) of the camera to bring the subject closer.
What is white balance?
White balance (WB) is the process of removing unrealistic colour casts, so that objects that appear white as you see them are captured as white in your photograph.
How to reduce camera shake
One of the most common causes of camera shake, particularly for new digital camera users, is not using the shutter release button correctly. It must be pressed down two steps: first to lock focus and exposure; second to take the photo.
The second most common cause of camera shake happens when the shutter speed is slow, or when using a long telephoto lens. The best way to prevent camera shake in these conditions is to use a tripod or other flat, level support.
What is a wide-angle lens?
Wide-angle lenses give you a view “further back” in the frame than your typical 35mm lens. They’re especially useful indoors, where you can capture more of a room in your photo. A lens is considered wide-angle when it’s 30mm or below.
