Photography involves using a camera to capture photographs. The photographer adjusts the camera's focus, aperture, shutter speed, and white balance to control aspects of the photograph like depth of field, light levels, and color balance. While the concepts and early experiments of photography date back millennia, the modern practice emerged through technical developments combining lenses, light sensitivity, and chemical development processes, starting with monochrome photographs and later incorporating color.

3. Camera... FOCUS - The adjustment to place the sharpest focus where it is desired on the subject. APERTURE - Adjustment of the lens opening, measured as f-number, which controls the amount of light passing through the lens. Aperture also has an effect on depth of field and diffraction – the higher the f-number, the smaller the opening, the less light, the greater the depth of field, and the more the diffraction blur. SHUTTER SPEED - Adjustment of the speed (often expressed either as fractions of seconds or as an angle, with mechanical shutters) of the shutter to control the amount of time during which the imaging medium is exposed to light for each exposure. WHITE BALANCE - On digital cameras, electronic compensation for the colour temperature associated with a given set of lighting conditions, ensuring that white light is registered as such on the imaging chip and therefore that the colours in the frame will appear natural.

4. History of photography... Photography is the result of combining several technical discoveries. Long before the first photographs were made, Chinese philosopher ‘Mo Di’ and Greek mathematicians ‘Aristotle’ and ‘Euclid’ described a pinhole camera in the 5th and 4th centuries BC. In the 6th century AD, Byzantine mathematician ‘Anthemius’ used a type of camera obscure in his experiments, Ibn al-Haytham (965–1040) studied the camera obscura and pinhole camera.

5. ... All photography was originally monochrome, or black-and-white. Even after colour film was readily available, black-and-white photography continued to dominate for decades, due to its lower cost and its "classic" photographic look. Ultraviolet and infrared films have been available for many decades and employed in a variety of photographic avenues since the 1960s. New technological trends in digital photography have opened a new direction in full spectrum photography, where careful filtering choices across the ultraviolet, visible and infrared lead to new artistic visions.
