In photography and videography, a filter is a camera accessory consisting of an optical filter that can be inserted in the optical path. The filter can be a square or oblong shape mounted in a holder accessory, or, more commonly, a glass or plastic disk with a metal or plastic ring frame, which can be screwed in front of the lens or clipped onto the lens.Filters need to be coated to reduce flare, and this reduces (slightly) the amount of light that passes through the lens.Filters are (normally) fitted at the very front of a lens and because of this they ‘attract’ flare. Lenshoods are essential when filters are used, but there are many circumstances where a lenshood used without a filter will prevent flare but cannot prevent it when a filter is fitted. Filters allow the photographer to have more control of the images being produced. Sometimes they are used to make only subtle changes to images; other times the image would simply not be possible without them. Read the rest of this entry »
A digital camera (or digicam) is a camera that takes video or still photographs, or both, digitally by recording images via an electronic image sensor. Most 21st century cameras are digital.
Digital cameras can do things film cameras cannot: displaying images on a screen immediately after they are recorded, storing thousands of images on a single small memory device, and deleting images to free storage space. The majority, including most compact cameras, can record moving video with sound as well as still photographs. Some can crop and stitch pictures and perform other elementary image editing. Some have a GPS receiver built in, and can produce Geotagged photographs. Read the rest of this entry »
Histogram is a feature in a DSLR camera that is often under-utilized by its users because of lack of understanding as what and how this histogram function works. Histogram, in general, can be viewed on the LCD screen by pressing the “info” button located next to the screen. Read on to learn more about what histogram informs the users about their photographs.
The X axis in the histogram illustrates the level of brightness/contrast ranging from totally black (level 0) to totally white (level 255), and therefore there are 254 levels of contrast in between. The & axis illustrates the pixel distribution in each level of said contrast.
Generally, a good photograph has a hill-shaped histogram with no cut-offs at the edges and at the peak of the hill shape. I say “in general” because there are some types of photographs (like a high-key, low-key, or night shot) where the histogram does not form this hill shape.
