Pixel Quality

In digital photography, when we hear the expression “more megapixels” we tend to believe that “more is better”. But in this case “more” doesn’t necessary mean “better”. The photography quality depends on a multitude of factors, the number of pixels being just one of them. Each pixel value has a quality that can be described […]


To understand the term of digital sensors we have to imagine an array of buckets collecting rain water. Digital sensors work the same way buy they consist of an array of pixels collecting photons, the minute energy packets of which light consists. The light sensitive photodiode converts the number of photons collected in each pixel […]

Micro lenses

Microlensses are usually placed on top of the color filter array on certain sensors of digital cameras, their principal role being to overcome the limitation of a low fill factor. Microlenses are also used in order to funnel the photons of a larger area into a smaller area of light sensitive photodiode. Microlenses are small […]

Manual focus

There are two ways of focusing: the automatic one (built in your camera) and the manual one (by hands). When you use manual focus the automatic focus is disabled. Usually, manual focus is used when you have to deal with low light or macro/special effects while taking a picture. With some digital cameras, manually focus […]


The LCD is used as a viewfinder by digital compact cameras. To be able to use it you need to capture a live video feed of the scene, which is provided by the LCD. The LCD’s normally measure between 1.5″ and 2.5″ diagonally, with typical resolutions between 120,000 and 240,000 pixels. But there are LCD’s […]
