IVP4403 - New Media (3 & 4)

These two lessons were on the different functions of a manual camera which are way too technical for me.....all the info below are 'stolen' from other websites... the purpose of putting all these info here is so that i can read them, understand them, learn them by heart, refer to them without having to search for all these websites again....  

most of the time, auto focusing works but not where there is no contrast in the area (blank wall) to be photographed. To overcome this problem, just have to place an item in contrasting colour in the middle of the blank wall, half press the shutter button, remove the item and full click....=)

(one shot vs AI focus vs AI servo)

"One-shot is for focus-lock. When you half-press the shutter release, the focus will lock regardless of camera motion (recomposing, for example) or subject motion. For stationary subjects, One-Shot is the usual preference.

AI Servo is for continuous tracking of subjects that are moving nearer or farther away. While you half-press the shutter release, the focus will continually track the subject that's located under the center AF point. This means that you need to keep the center AF point over the subject at all times, which can be challenging with a moving subject. That, in turn, means that your subject will be centered in the photo, so your composition options are extremely limited.

AI Focus - Don't use this." - source

shutter speed + aperture + ISO

a website that allows beginners to practice varying the 3 components of exposure.... 


is about controlling motion with the amount of light entering your camera
The (TV) mode refers to the shutter priority shooting mode used in semi-automatic cameras. It allows the photographer to choose a shutter speed setting and allow the camera to decide the correct aperture. 

- B (for bulb) keeps the shutter open as long as the shutter release is held.
- T (for time) keeps the shutter open until the shutter release is pressed again.

A short shutter mostly requires a lower aperture value and the aid of a tripod. 

Very short shutter speeds can be used to freeze fast-moving subjects while very long shutter speeds are used to intentionally blur a moving subject (misty water / clouds) for artistic effect.

is the adjustable hole through which light passes on its way from the subject, through the lens, to the digital sensor or film.

A smaller f/number will represent a larger aperture which means that more light passes through, resulting in a smaller depth of field (DOF) and vice versa. 

A low aperture gives a blurred background while a high aperture shows everything to be in focus.

(c) ISO
The lower the ISO (100-200), the smaller amount of light the camera will use. So ISO100 is sufficient for taking pictures outdoor on a really bright sunny day.

The higher the ISO, the more light the camera will use. So ISO 800 or higher is needed when taking pictures indoor without a flash. However, high ISO will make the pictures grainy. 


(combining the 3)

to take flowing motion pictures:
- decrease the shutter speed (shutter opens and closes slower letting in more light)
- increase the aperture number (making the hole smaller letting in less light). 

to take blur background (shallow depth of field) pictures:
decrease the aperture number (increases the hole size letting more light in)
- increase the shutter speed (shutter opens and closes faster letting less light in). 



everything i need to know about white balance can be found in this website . Basically, it's about getting white to look white even in yellow / orange lighted room. 


presenting my tutor's wonderful illustration.... =P 

so after learning about all these, we are tasked to do two technical challenge which i seriously need help in.... 

(1) wide angle + long exposure + theme: ghost of the past
(2) telephoto + freeze frame + theme: i'm alive

so any kind soul who's reading this and have fantastic (and Candy do-able) ideas, please let me know..... best if you can give me photography tuition lesson at the same time too...=)
