When pointing a DSLR camera at a desired object, light from the object travels through the camera’s lens, into the camera body, onto a light censor chip. Once the shutter on the digital SLR closes (when you push the capture button on the camera) the light censor chip, which is typically referred to as a charge coupled device (CCD) absorbs and reads the amount of light passing through the lens and stores the data as a digital file. The file is then saved onto the hard drive of the digital camera or on an inserted memory disk. You can then view the captured image on a computer.

Joseph Nicephore Niepce invented the first photograph in 1826. This French inventor produced the photograph a pewter plate that was covered in a petroleum-like substance known as bitumen of Judea. Joseph dissolved the photo in another petroleum that was white in color, which washes away to expose a shiny polished metal plate.

William Henry Fox Talbot created a process prior to 1840 that utilized silver chloride to process negatives on sheets of paper. The method was known as calotyping and allowed a person to reproduce a positive image from the negative photographs.

The first colored photograph was not taken until 1861, by James Clerk Maxwell. Autochrome debuted on the market in 1907 and utilized dyed-dots of potato starch to produce the photograph.

Pictures continued to morph into what they are today; however, Texas Instrument did not manufacture the first film-less picture until 1972. The first professional digital camera appeared on the market in 1994, when Kodak released the Nikon F-3.

Even inexperienced photographers understand that exposure settings adjust overall photo brightness. Cameras resemble the human eye and posses exposure settings, which control the amount of light entering them. The aperture, equivalent to the human iris, can be set wide for more light and narrow for less. The shutter, similar to an eyelid, will ‘blink’ fast or slow for lighter or darker photos.Never heard of this before? Get up to speed here. A camera’s sensitivity is comparable to human pupil contraction and dilation, letting in more or less light accordingly.

The brightness of surfaces in a shot varies, so exposure settings are adjusted to account for their relative brightness to each other. For example, when photographing a subject wearing a white t-shirt, standing in before a pale sky, exposure settings must be altered, enabling the subject to be visible.

However, these settings don’t only adjust overall brightness; they also offer the opportunity to get artistic with images. Faster shutter speeds freeze moving objects, and slower speeds create a motion blur, giving the photo dynamic appeal. Aperture settings have significant effect on depth of field in a photo. Narrow settings produce photos with the entire scene in focus and wide settings enable single subject focus. Adjust overall brightness of photos by ramping up sensitivity and fiddle with aperture and shutter settings to add interesting dimensions to your photos.
