Night Photos of traffic getting the light right
« on: August 29, 2006, 09:23:37 AM »
On holiday in in Lisbon for a couple of days and wanted to get a couple of photos of the traffic at night down the main avenue.  Tried decreasing speed to about 10 seconds f22 iso 100 but don´t get the red tail lights showing - not sure whether the ambient lighting is too strong or the cars too fast (they seem to think it is a drag race from lights to lights).  Any tips would be appreciated today before I try again this evening (i.e.would increasing ISO to 400 help).

ps Seem to have hundreds of animal and bug photos from this holiday (comes from keeping a five year old amused) and will post the best once I get home and have waided through them

I tried some night shots and i t seems to depend on ambient lighting.
Try around 2-4 secs or if you have the space start at 1 second and work up.

I think in one of my posts recently I had some night shots of the junction near use (shot through a window). Have a look see what you think :)

At 100kph a car travels 27 meters per second. That is a loooong light trail at (say) one second exposure.

See image below ... This was taken at 2 seconds. It was early morning in a village and the car was likely traveling at 20 kph or about 5.5 meters per sec. I'd guess those light trails are perhaps 10 m in length--maybe a bit less, but I don't know the car speed -- rather slow.

Of course, a tripod is a must. The cool part with digital is that you can test exposures as you go.

motorways are good ,no steet lighting, so you can leave the shutter open for longer. Just after sunset is favourite you still get some colour in the sky. exposure time as long as you like really. cover the lens when no traffic.
Avoid scenes where sya the cars appear in one spot eg over the top of a hill that spot will overexpose.
Got some niceones from near high Wycombe. The mway comes down a hill then pefroms an s bend on a viaduct and climbs a hill on the other side. I will have to dig them out.

OK so here is what I managed to get by shortening the time plus some comparison on longer exposures

2 sec F8 28mm ISO100


15 sec F22 28mm ISO100


1.5 sec F22 28mm ISO100


Same shot but at 4sec F4.5 got overexposed but liked the result (just tweaked the contrast down)

Fantastic results!

I think you've posted them in order of excellence - the first is a great shot, the second really good.....

very impressive stuff :D
