Mission for Canon EOS 400D owners

Post by bloodhound31 »

Hi all,

I have a special mission for anyone with a Canon EOS 400D (AKA Rebel)DSLR and a standard 18-55 Lens.

I am writing an article on light pollution.

All I need is a photo from the capital cities listed below.
I will choose from several submissions if anyone is interested.

Please PM me with your interest and I will provide image capture parameters.

I will publish the link address to the completed article on the forums, with image credits listed for those chosen.

Cities in random order:

Sydney
Tokyo
New York
London
Moscow
Beijing
Paris
Berlin
Cairo
Singapore
New Delhi
Buenos Aires
Copenhagen
Athens
Rome
Baghdad
Wellington (NZ)
Abu Dhabi
Washington D.C.

Cheers,

Baz.

Due to the lack of response, I have decided to do away with this list of cities. I will take entries from any large city in the world.

I'm not sure why I have has so little interest. So far only one person has actually delivered a photo. I feel the subject of light pollution is likely to be something near and dear to all astronomers/astrophotographers hearts.

Anyway, the offer still stands, if you want to help out, please PM me and I will provide image capture details so you can snap a bit of your night sky and send it to me.

Remember- in an effor to control the different sensitivities of sensors, Canon EOS 400D's only.

Looking forward to your efforts,

Baz.

Might it be that the number of people who have a 400D, live in one of the named cities, read this BB, read this forum in this BB, have an interest in astrophotography, have the 18-55 kit lens (which was rather unpopular from what I've read) and have the time to get involved is rather small?

I did try and promote it for you on my weblog (which gets picked up by Planet Astronomy) but it's not like I've got that many readers.

Perhaps it would be a good idea to approach one of the more popular astronomy weblogs (Astronomy Blog, Tom's Astronomy Blog or Bad Astronomy, for example) and see if they'll give it a mention? Might also be an idea to provide contact details other than using PM on this BB so non-BB members can get involved?

I'm hearin' ya Dave.

I have posted this on many, many forums. If anyone here wants to spread the word, please do so.

I really don't want to provide contact details on such an open front, only to those who are prepared to do me the favor. PMs ar only a small filter, but effective enough. Besides, if someone genuinely wants to help, then a PM is not much of a step.
They will have thier name up in lights and be hailed as a photographic celebrity by the time I get finished with their pulitzer winning image.... :lol:

Hi Bloodhound,

I've looked at your post and, to echo Davep, agree with him in that your target market is tiny....a better suggestion, perhaps would be to ask people to send in their pictures from a DLSR set at, say, ISO 100, f5.6 and a 30 second exposure.....then at least you would have a basis for the camera settings.

Although not living a in a city, I would submit an image from a large town to highlight the fact that light pollution does not just affect cities. I use a Canon EOS 5D.

By the way, you must stipulate that the image is not edited in any way at all to ensure an even playing field. Also, you may wish to take into account cloud cover. I have images that were taken through a very thin layer of cloud, and of course, the image looks worse for light pollution that it actually should, because of the light mist/cloud. There are more variables to consider than just camera type and lens combination I'm afraid to get a good grasp of the problem of LP. Other things to consider would be: The time of night the image for submission should be taken, nearest street light, nearest building, moon phase etc, etc.

Without taking these points, and others into consideration (irrespective of camera type/lens type/settings), your results, although proving a problem of light pollution would not ALL be on a level playing field and be wide open to scrutiny. Two people in London, for example (one in Piccadilly Circus and the other in St. James' Park) with identical cameras, set-ups etc take a picture at the same time on the same night would show totally different results and therefore not give you a true representation of the LP problem in London as a whole.

You could be maiking a point here with your idea, but without opening the playing field to encompass as many people as possible, well, you know what the nett result will be.

Thanks Martin.

I hear you, but I have already taken everything you just said into consideration. As I said in the first post, if anyone is interested I they can PM me and I will email them or PM them the capture parameters. All the specifics are there, but I want to keep this project my own, and not have others pinching my idea before I am done. Hopefully the people who want to help will have the integrity to keep it quiet until I have published the article.

Different chips have different sensitivities. The Canon EOS 400D (AKA Rebel) is a very common camera at present. This is an attempt to control the capture device for a true comparison. Thats all. If I open it up to other camera's, then I have missed the whole point of the original idea and exercise.

I am a patient man and am willing to wait as I think this project is worth it.

Please, If you do know anyone with a 400D, ask them if they are willing to take a snap or two on my behalf. They will be famous with their name in lights on the bottom of their photo. :P

Keep at it! There are a small number of good people out there who will help you, but make no mistake, most others are just NIMBY moaners. Margaret Thatcher was right when she said 'there's no such thing as society'. Me, myself and I, as the song went...

Good luck!

Dear Flying Astronomer
More than a decade ago I was a NIMBY who objected to a large supermarket being built in our area. When it came to the count there were one helluv a lot of us NIMBYs, indeed so many that the our local council chucked out the supermarket proposal. What happened then the Supermarket appealed and after tremendous wrangling and a farcical public enquiry supermarket got approved. It is worthwhile mentioning that a very important share holder of the supermarket was a politician (I will not mention names or political party) was not long afterwards found guilty of gerrymandering (basically vote rigging) and serious tax evasion. That supermarket\politician scarperred to another country, eventually returning several years later after paying £17 million pounds - which was about half the tax really owed.
I am afraid your ideas of what constitute society and mine might be somewhat different, they are certainly very different to those of two political "ladies". As a result of the supermarket shinnanickens we now have a very signicant increase in light pollution and traffic. As for the gerrymandering supermarket tycoon I imagine they subsquently lived a life of Riley with the £17 million spare cash. Society - what society, whose society ! The NIMBYs who live here or the tax evaders who possibly own half of the supermarkets.
Best of luck from Cliff

The majority are good people but as DaveP has already suggested, only a small percentage will be able to take part.

Also, Baz, it is difficult to both keep your project secret and enthuse others enough for them to want to participate.

HTH,

Steve :)

Indeed. I'd have loved to have taken part given that I appear to have all the right equipment but given that I don't live in a major UK city (or even a minor city or town) it would have been difficult.

The NIMBY suggestion above is unfortunate.

Hi Dave, If you still want to participate with your "right" equipment, just send the shot from where you are mate.
