London at Night

#1 Sean

Very nice. Next time you feel like shooting the bridge at night, don't use an aperture smaller than 5.6 or 8. The lights won't starburst then and you should still get plenty of DOF for the detail in the towers. Were those all about 60 sec exposures? The D10 is something else.

They were 20 secs, 60 secs and 30 secs exposures in that order.

Thanks for the tip Sean about the aperture to use. Do you know why this prevents the starburst effect (which I kind of like)? Is this the usual aperture to use for night photography?

What is the maximum exposure length the D10 is capable of? I'm pushing up to half an hour with some of my exposures and I've yet to find a digital camera that will accomodate this.

According to the 10D manual:

"With a fully-charged battery, a single bulb exposure can be as long as about 2.5 hours."

but it does also say above that:

"Since bulb exposures will have more noise than usual, the image will look rough or
grainy."

Let's see if I can get the answer to sound somewhat correct.

Smaller apertures cause more diffraction of the light. The number of aperture blades determine how many streaks the starburst is going to have and the diffraction occurs where the blades overlap.

Make sense?

So you can actually control this effect to quite a fine degree?! No need for a starburst filter then

right, there's no need for a starburst filter. the number of points in the burst is actually determined by the number of aperture blades. since most cameras these days have an odd number of blades, the number of burst points is 2x the number of blades.

OK - I'll try out a range of different apertures next time and compare the effects. Thanks Sean!
