Case Study 2: Water Falls

This is the famous one... Capturing Water Fall at very slow shutter speed. I got hands-on in Colorado while hiking towards Adam Falls.

It was 8:00 in the morning at Adam Falls... Bright day but not sunny (because the Sun was behind high mountains).

Started taking picture at 5s and f/5 (keeping shutter speed as priority) but it was all white... after some trial and errors... I got this amazing one at 1s and f/32.

Key was
1. to increase shutter speed (from 5s to 1s) so that shutter closes "comparatively"  faster and offer less time for light to come in

2. to increase aperture value (from f/5 to f/32).. it in-turns decrease the diameter of lens so that it allows less light to come in.

In short, a perfect amount of light for longer duration of time to get this effect... flowing water fall.

Exif Data:
Shutter Speed: 1.0s
Aperture: f/32
Focal Length: 35mm
ISO: 200



Here is another photo of same place at (same ISO and focal length as above):
Shutter Speed: 1/500s
Aperture: f/5
