I like this line from Joel Lee, “most beginners think that the magic of photography happens in the body of a camera, but the true source of magic is LIGHT.” Yes it is true in photography, LIGHT is LIFE.
Every aspiring photographer need to get a real good deal pictures, must master factors affecting image processing. These factors are the APERTURE, SHUTTER SPEED, and ISO. Mr. Cooke explained that the triangle of these factors is not a geometry lesson but it is a common way of determining the exposure of a photograph. The three must have a balance to achieve the desired photos.
This refers to the size of the lens opening (f/2, f/5, f/11, etc). Try to remember that the smaller the number means a wider aperture opening, and the wider the opening, the more light is coming in. This also means that the larger the number, the narrow the aperture, the lesser the light. Aperture also affects the depth of field which results to bacground blur.
b.) SHUTTER SPEED
The shutter speed “is a measure of how long the shutter remains open and how long the sensor is exposed to light (Cooke,2017).” So, the faster your shutter speed, the sensor will have less time to collect light and result to a lower exposure. While if you have a slower shutter speed, your sensor have more time to collect light and will result to higher exposure. Many pro photographers prefer using high speed shutter to put sharpness to the inages they capture. Shutters are in 1/200 sec, 1/60 sec or 5sec form.
Adjustments to light sensitivity before was hard, but now we can already donit in just a click. ISOs enable you to work with lesser light, although you got a trade-off which is NOISE. ISOs come in 100, 400, 6400 etc.
To experiment the three factors, start to put your camera on a manual mode and CLICK, CLICK and CLICK! And before you know it, YOU already master it in your MIND & HEART.
I am not an expert, which is why I am doing lessons and research to become one. And I am sharing my lessons with all of you. I lobe to take pictures but I must admit, they are not good enough because I do not know the basics. So I am now learning it, and I hope you do too.
Till the next lesson on the RULE OF THIRDS.
Post comments to add to my learnings. Keep reading, learning and enjoy! #photographylessons
