Part 1
This exercise explored the differences between daylight and tungsten lighting. I stood close to the window inside a room just after sunset when there was a little daylight left and looked out for about one minute.Turning back to look at the room light,it appeared darker .As my eyes adjusted, the light seemed to become lighter. Turning back to the daylight outside, this now appeared to be a darker colour.
Measuring the light level in different parts of the room, I found the reading close to a reading lamp to be 1/8 @ F8 and in the darkest corner it came out at 1/6. At full aperture ( F4 ) the shutter speed came out as 0"4 not sufficient for hand - held shooting unless unlike myself you had a very steady hand.
I then composed a photograph in which both the interior lit by a tungsten light and the exterior at dusk were both visible. Three images were taken with the white balance set to Auto, then daylight and finally to tungsten. The differences between the images were as follows:
Auto white balance
 |
| P356: f4 @ 1/3 ISO 800 18mm |
Daylight
 |
| P357: f5 @ 1/3 ISO 800 18mm |
Tungsten
 |
| P358 : f3.5 @ 1/3 ISO 800 18mm |
Part 2
For this part of the project, I took photographs of two different interiors, a tube station and inside a train carriage at night. Each interior was shot first using the white balance set to auto and then to fluorescent.
 |
| P359: f3.5 @ 1/60 ISO 1600 4mm AWB |
 |
| P360: f3.2 @ 1/60 ISO 1600 4mm |
 |
| P361: f3.5 @ 1/60 ISO 1600 4mm AWB |
 |
| P362: f3.5 @ 1/60 ISO 1600 4mm |
Looking at the above four images, I think none are very satisfactory in respect of colour representation either from how the scene actually looks now but also how I remember it ( given that this could quite likely be different to the actual reality).
