Light pollution images around the world

Hi all, some time ago I asked for pictures from people all over the world to capture the light pollution in major cities.

Many people responded, and quite a few followed through. An article was written and the images were posted here.
It is with humble grattitude I truly thank all those who submitted images.

I would like to extend the request for more images from anyone here who can comply with the capture parameters listed in the article.

Would love to hear from you,

Baz.

Any takers?

All that is required is a 30 second exposure at night.

Your name will be credited to the image.

I will try and take a shot at the weekend if the weather is ok!

I'm still learning on my first DSLR camera (XSi), so forgive me for asking what is undoubtedly a "noobish" question, but how, exactly, does one take a picture with a 30 second exposure? I've done some experimenting taking pics at night of cars driving down my street where you end up with those neat streams of light, but nothing approaching 30 seconds. I'd be happy to submit a pic, what settings would you reccomend?

Sorry, you do not have the specified camera. He needs the exact settings/ parameters duplicated for his study.

Although, basically you'd need a tripod and remote switch. The camera's shutter is set to Bulb, which means the shutter is open until you tell it to close. My wired remote switch has a lock feature, so it's easy to keep the contact closed. On my XTi there is a timer that shows up when you trip the shutter. The kit lens used here is set to Manual focus. I had to snap a few trials to get the focus as clear as I could. I also went into the custom functions and told the camera to flip up the mirror, to stay any vibrations that might have shown up when the shutter was tripped.

I have quite a few examples of light pollution in California.

Here is one:

I meant to loan a pic to you last time but didn't have good weather at the time.

Is it ok if I use my 40D and 24~105mm or do you need a differnt setup?

Any deep canyon will meet your needs, no reflected light from a hole.

Eric,

The 40D should be fine, I think the chip sensitivity is the same as the 400D(XTi). If you are going to use the 24-105mm, then shoot at 24mm and as close to F3.5 as you can get.

Look at the other examples to see what sort of shot I am after.

The idea is to see how bad the normal light pollution is. NO enhanced processing.

For everyone else, look at the link in the first post and you will find the capture details. Try not to stray too far from them.

Thanks Ian, I will keep an eye out for you.

Cheers,

Baz.

Gotcha, I have a set aperture of no larger than 4.0 so that's what I will have to shoot at.

I also have a 50mm 1.8 that I could stop down to 3.5 if you prefer that.

Have a go at both if you like and send them. You may as well if you are out there anyway.

How bizarre, I was only out last night, taking a few shots in hopeless conditions, and thought to myself, "How about starting a thread for people to show me photos of what sort of light pollution they have to contend with?". And here the thread is!

I'll take some soon.

In the mean time, here's a small idea of what I have to contend with sometimes. About 300 yards south of my house is an Army Camp, with a floodlit football pitch. It's not normally in view, but I was out on the fields last night and took this 10mm, f/3.5, 2s wide-angle of the moon and Jupiter, with the stadium just noticeable towards the left.

Then this 50mm. f/1.8, 1/4s shot of the Stadium under attack by celestial jellyfish! (I wish!)

Terrible that you have to contend with such.

Although, my request for LP photos is trying to avoid direct light and capture the ambient light in the sky itself.

Nice shots though.

Baz.

Ok, the full moon is waning now and getting up later each night....start planning your shoot folks, and GET ME THOSE PHOTOS!

Baz.
