Outdoors at night

I chose to look locally for subjects for this exercise including Portsmouth city centre, the M27 and nearby Cosham. My intention was to explore the variety of lighting effects and colour found in artificial light. I used a tripod for most of the shots but not  P371,P372, P376 and tried out  a variety of settings before achieving the following images.

P365: f5.6 @ 3.2sec  ISO100  55mm WB - daylight 


P366: f3.5 @ 1/30  ISO 1600  21mm  WB- daylight


P367: f3.5 @ 0.6  ISO 100  +1.7exp. 24mm AWB 


P368: f5 @ 1/3sec  ISO100  37mm  WB- daylight


P369: f4 @ 1.3   ISO200  25mm   AWB



P370: f4.5  @ 3.2sec  ISO100  34mm  WB- daylight

 

P371:  f3.5 @ 1/6  ISO 100  + 1.7exp.  18mm  WB - daylight



P372 : f3.5 @ 1 sec ISO 100 22mm WB -  daylight


 
P373 :f29 @ 1/3  -1.3exp.  ISO 3200  34mm AWB


P374: f22 @1/3  -1.3exp.  ISO 3200  18mm



P375: f3.5  @ 1/160  ISO 1600  +1.7exp.  4mm  AWB 


P376: f4 @ 1/60  ISO 1600  15mm  AWB


P376a: f36 @ 1/3  -1.3exp. ISO3200   55mm  AWB


Apart from the challenge of finding shop windows that were brightly lit, I found images reflected in the window glass posed a problem in some cases which sometimes could be resolved by changing the angle of the camera. Back lit screens in bus shelters and in one shop ( see below ) also proved a challenge as in finding an exposure setting to reveal the image on the screen resulted in loss of detail in the dark foreground and back ground. This is fine if you do not want that contextual setting as in P376. I tried a variety of settings but as the image below shows did not 'crack' the problem. Interestingly, the reflected image of the screen on the left produced a better exposed image presumably because there was less light to cause over exposure.



P376b : f20 @ 1/6   -1.3exp.  ISO 3200  24mm
