not mine but very cool...

There is software available for merging many medium exposure photos to get the stars moving across the night sky... this just seemed like a really inspired photo to me...

Anyone else done anythig interesting with light?

Wow great find Squidders

I`ve been up there many times but never envisaged it like that.

 

[Squidders]

Yeah, I've been climbing up there loads... that just struck me as way cool!

I like that he got the north start dead bang in the middle of the pic too... it's a great shot.

probably not merged photos - more likely a long exposure..

i've had a play in the past with stars and car trails:

Thanks for finding this - excellent photo, great idea.

That's a great photo, thanks for the link Squidders

Actually, I have a very very strong reason for thinking this is a series of exposures that have been merged.

come on then... spill the beans... I like new techniques to play with

naah... it's a shortcoming of digital...

very long exposures ... 5 minutes plus... tend to heat up digital sensors and generate a fair bit of noise in the image. This image doesn't have any.

Also, there have been documented cases of people trying 20+ minute exposures and having their sensor go pop. pretty alarming.

Other than out and out resolution, it's the one edge film has over digital as film can easily deal with 5 hour exposures.

I have also seen some very nifty software for sorting out multiple exposures of stars at night. very cool stuff.

reading through the comments below the photo it looks like it was a 12 minute exposure at ISO 100

I know what you're saying about the noise though. The top picture of my 3 was about a 1 hour exposure IIRC in raw and the conversion software I was using did a pretty good job of removing the noise - unfortunately, converting to a small, heavily compressed jpeg to post it on here has put noise back into the shot

was taken on a Canon 10D btw

well spank my left buttock and call me shirley... I could have sworn that part of the crag was at stanage plantation and would have taken longer than 10 minutes...

I guess that makes me even more wrong... still... I don't think I'd put my sensor at risk doing it that way.

are free stacking utilities that won't risk damage to your sensor.

you win this round bikething... and it would have worked if it wasn't for those meddling kids!

Last time I was up there it took me about an hour to get up a Severe......

longest I've tried for is 3 hours.... but the camera batteries went flat after 2 and a bit in the cold

look on the bright side - you've given me links to a couple of new bits of software to play with in the dark winter evenings - cheers for that

 

[Squidders]

aye... have fun with them... and be careful with your sensor mate... I have heard people saying it's a myth... and it is until your camera needs an expensive fix.

 

[Cobweb]

The older cameras like the D70 are prone to the sensor overheating but it's been said that the newer ones are fine. I've done an hours exposure on the D200 and it was fine. If you are planning on long exposures, consider getting a battery pack or an a grip that allows you to add an extra battery, long exposures require a lot of juice.

Nice pic Squidders

 

[Pang]

cooool, thnaks

Dartmoor Inn at Merrivale, bikething? Nice pictures people.

I took this a few nights ago, small plane flying by, bit pixely as i had the iso set too high,

Not light painting but a 20 second exposure, i like the colouring against the trees

Taken last year camping, i like messing around light painting.
