Introduction to Photography PROF. SALMA YOUSSEF M. KAMEL  Etymology ‫علم أصول الكلمات‬ The word photograph was coined in 1839 by Sir John Herschel based on the Greek φῶς (phos), meaning "light," and γραφή (graphê), meaning "drawing, writing," together meaning "drawing with light."  ‫?‪What is a photograph‬‬ ‫الصورة الفوتوجرافية هى إيقاف لحظة من الزمن بكل سعتها البصرية والتعبيرية واإلبقاء عليها مدى الحياة‪.‬‬ Getty Images, Inc. is a British-American visual media company and is a supplier of stock images, editorial photography, video and music for business and consumers, with an archive of over 200 million assets.

Exposure is one of the most fundamental photography terms. When you take a picture, you press the shutter button to open a camera's aperture and light streams in, triggering a response from a sensor. Exposure is the amount of light that reaches your camera's sensor, creating visual data over a period of time.  ‫هى قيمة حساسية السنسور للضوء‬ ISO IS THE SPEED OF LIGHT SENSITIVITY OF THE CAMERA SENSOR  ‫‪ISO Comparison‬‬ ‫تزيد الضوضاء ‪ Noise‬مع زيادة قيمة الحساسية ‪ISO‬‬ In full frame cameras, noise is reduced due to the size of the photocell. The photosite responsible for recording the light entering the lens is larger than that of the smaller sensor.  APERTURE/ F- STOP 1. Controls quantity of light penetrating the lens. 2. Controls the depth of field (DOF) 3. Controls sharpness. EFFECT OF F-STOP  SHUTTER Controlling time which the light affecting the sensor Synchronizing with flash light. ‫يتحكم فى الزمن الذى يؤثر فيه‬.‫الضوء على حساس الضوء‬.‫يتزامن مع سرعة الفالش‬  Effect of shutter speed on moving objects. ‫تأثير سرعة الغالق على أسلوب تسجيل الحركة‬
