J 28 001
margin of error:
we have reached the limit of the method that uses measurements and points in mid and background.
Movements within 5 metres are too refined for the method of calculating background and midground features.
A qualitative assessment comparing J27 - 003 location 7 and J28 - 001 location 8, shows that we move up and/or forward to make the foreground smaller.
1. move up 10 cm from J27 - 003 (108 cm height to centre of lens)
2. move forward in 25 cm increments
