Basics 02

So here I am with a series of chapters, in which I am going to tell you about the basics of composition and layout, photography, typography, etc. This series will surely give an idea to the beginners what they are stepping into and what basics they must know. This series will have Six chapters. I hope you are going to like it.

Chapter 2: Photography

• Resolution - Number of pixels in an image
• DPI - Dots per inch that is used in printing.

300 dpi  = 1200 X 1800 px

i.e. = 4" X 6"

It is very important to pay attention to for work created in CMYK that will be printed. The term refers to the amount of the dots of ink per inch within an image. Again the higher the amount the better quality the image.

• PPI - Pixels per inch used in digital and electronic devices. RGB colors are used in this.
• Pixels - Smallest building blocks of a digital image. Pixels also have sub pixels which are not visible to human eye. These are of square shape.
• Bleed - Extra edges to avoid white boarders while printing.
• Trim - Final size of a printed piece.
• Crop - Crop or cut which are unnecessary parts.
• Stock photo - Licensed photos created by a third party.
• Aperture - The adjustable opening of a lens determines how much light passes through the lens on its way towards the mirror sensor. The wider the aperture is set, the shallower the depth of field. Faster lenses have wider apertures, which in turn allow faster shutter speeds.
• Shutter speed - The length of the time the shutter remains open when the shutter release is activated.
• Focal length - The distance from the lens to the film plane or sensor that focuses light at infinity. Shorter focal length offers wider angle of view.
• Depth of field - Measure of how much of the background and foreground area before and beyond your subject in focus.
• Exposure - Exposure is the phenomenon of light striking the surface of film or a digital imaging sensor. It is determined by the volume of light passing through lens aperture combined with the shutter speed.
• Aspect ratio - It refers to the shape or format of the image produced by a camera.
• ISO - International organization of standardization. A number indicating an image sensor's sensitivity to light.
• DSLR - A single lens reflex (SLR) camera that captures digital images. It includes a camera body with interchangeable lenses.
• Megapixel - A megapixel contains 10,00,000 pixels and is the unit of measure used to describe the size of the sensor in a digital camera.

Fun fact - 'Since B donates blue and black both it will be confusing. In CMYK blue is called cyan. Also Black is donated by k.'
But why K?

Black is the key color, which combines the rest of the 3 colors.
