Visible light has a wavelength in the range of about 380 nanometers to about 740 nm between the invisible infrared, with longer wavelengths and the invisible ultraviolet, with shorter wavelengths. WHAT IS THE PHOTOGRAPHY PHOTOGRAPHY The word "photograph" was coined in 1839 by Sir John Hershel and is based on the Greek φῶς (phos), meaning "light", and γραφή (graphê), meaning "drawing, writing", together meaning "drawing with light“ Photography is Art created by Light All photography is based on light Digital camera anatomy An Image Sensor is a device that converts an optical image to an electric signal. Crop field / Талбайн таналт Exposure is the total amount of light allowed to fall on the image sensor There are three factors which influence the exposure of your image:
-Aperture
-Shutter Speed
-ISO DEPTH OF
FIELD Shutter speed refers to the length of time the sensor is exposed. Shutter speed typically ranges from 1/4000 second to 30 seconds long. It mainly deals with motion. Refers to the light sensitivity of the sensor
HIGH ISO value means the sensor will be MORE sensitive to light, meaning it will take LESS LIGHT to get the right exposure
Typically ranges from 100-3200
Newer Digital cameras have a higher range (up to 12800)‏
Using High ISO values causes the sensor to produce much more heat, which creates digital “noise” in images. Noise is similar to film grain and causes loss of fine detail in images
It is more visible in dark parts of an image and is generally more noticeable when displayed on screen than in print HDR DUST REDUCTION REMEMBER PRACTICE MAKES PERFECT Thank you for your attention These optical elements are lenses arranged in such a way that they direct the path of light to recreate the image as accurately as possible. Needless to say, the longer the focal length, the more will the number of optical elements.

Based on construction, the two main categories of lenses are:
Prime lens
Zoom lens
TELECONVERTER EXTENSION TUBE
