On my hobby and interest list is to try my hand at both woodworking and photography.
My local college offers a large number of adult evening courses and I have been keeping an eye on what’s available. First up that caught my eye recently was an 8 week course, one evening a week, entitled “Photography for beginners“.
This short course is for beginners who would like to use their DSLR camera more effectively.
Students will focus on getting to grips with their camera’s manual functions, understanding aperture, shutter speed and ISO, and exploring how to use these creatively.
By the end of the course you will be able to creatively use your DSLR camera in manual mode
Sounded ideal, so I signed up and am one session in. Wood working will have to wait ’til later.
My Takeaways from Session #1
Digital Single-Lens Reflex (DSLR) camera
Digitally recording captured light on an image sensor
The amount of light captured is controlled by shutter speed and aperture size.
ISO completes the “magic triangle”
Larger aperture size = more light captured, brighter image
Slower shutter speed = more light captured, brighter image
Higher ISO = higher sensitivity to light, brighter image
My Takeaways from
Adjusting any of these comes with consequences
Increase iso ( 100 → 200 → 400 → 800 → 1600 → 3200 → 6400 ) = more light captured, more noise
Adjusting any of these comes with consequences
Increase aperture size = more light captured, greater depth of field
Decrease shutter speed = more light captured, more motion blur
