Today, we will recap on the fundamentals of working on our exposure with an SLR including selecting appropriate shutter speeds, apertures and selecting an appropriate ISO.
This is very similar to my previous post on Aperture and DoF.
The image on the left has higher F number. Whereas, on the right has lower F number as it pinpoint the focus level. This allows the viewer to focus a specific part of an image. The blurry part could either be an enigma for the audience to guess or for the audience to ignore.
Adjusting shutter speed can make you feel differently. For example:
It can show you a time-lapse of an image, to understand the movement of its subject(s)
Or it can completely stop time and allow you to see things, that normal eyes can’t see.
3 things to consider, whilst using a shutter speed:
- Hold the camera steady
- Use a tripod
- Think about camera shake
The reciprocal relationship between aperture and shutter speed:
Remember: Light + Time = EXPOSURE!
This is the exposure triangle. You can control this through digital camera and can use hand held light meter to measure it.
