At 3 m a flash meter reads f/11. If the flash is moved to 6 m with power unchanged, the reading becomes: / 3 मीटर पर फ्लैश मीटर f/11 पढ़ता है। यदि फ्लैश को पावर बदले बिना 6 मीटर पर ले जाया जाए, तो रीडिंग होगी:
1.
f/8 / f/8
2.
f/16 / f/16
3.
f/5.6 / f/5.6
4.
f/4 / f/4
Correct Answer: f/5.6 / f/5.6
Doubling the distance quarters the light (inverse square law), which is two stops less: f/11 down two stops is f/8, then f/5.6.
