forgot to mention that you might like to look at smugmug.com for better quality video sharing. for an annual fee, you can even upload Full HD resolution video which viewers can choose to watch at whatever resolution their connection supports. and you can embed decent quality video as well.

A masterpiece Alex. It was also nice to meet you and get your advice on lenses and cameras.

A winner for sure for next year taken just before the awards!!

Greg.

You need a panoramic head like this:

It allows to rotate a lens around a "no-paralax point" and has a click-stop rotator which is very useful at night.

With 10.5mm lens on a full frame body I do four shots in portrait orientation at 15 degrees angle looking up (on a D300 you will need 6 shots). Then I use PTGui and stitch the 360 spherical panorama, which is a bit tricky with night time shots and I sometimes have to use manual control points on the stars. I then convert to Flash in Pano2VR.

There are a few good online resources on panoramic images, I found this one a good start:
http://www.panoguide.com/howto/

If you get to doing those and have any questions just give me a shout and I will be happy to assist.

Cheers,
Alex

Thanks Phil - the most expensive 9V DC adaptor from Nikon ($170 !!!) has arrived in the mail today . I had to get it from Nikon because of the custom socket I could not find anywhere.

Could you upload a smaller version of your animation for those of us that are connectionally challenged.
Thanks Paul!

I uploaded the time lapse to vimeo:

Thanks again for very nice comments everyone!

I could not resist making a "little planet" projection of the same 360 panorama (attached).

Cheers,
Alex

That's a wonderful image. How do you do that little planet effect?

What camera and lens did you use here. Was it the 14-24 and Nikon D3?

I just love it.

Greg.

Thanks Greg!

I did this one with Nikon D700 and 10.5mm fish-eye. This lens with removed hood covers about 200 degrees so I only need four or even three images to make the 360 degrees spherical panorama.

I made a 360 panorama with 14-24mm lens before and it needed 2 rows of 6 images each. Although the 14-24mm lens produces much higher resolution panoramas (50MP vs 24MP with 10.5mm) it is a real pain to stitch.

The "little planet" is a stereographic projection (used in cartography to map the Earth) - one of many available in PTGui software I use for stitching panoramas.

Cheers,
Alex

Alex,

Thanks twice over, firstly for the inspirational images and video, secondly for keeping my mind occupied during a waxing moon and rainy nights.
I've been going nuts making pano pictures in my lounge room gotta start small

Thanks Alex.

With time lapse imaging, do you need special software to stitch together the time lapse images?

How do you handle the transition from day to night? Estimate the ISO and exposure for night or can you change it once it has started?

Greg.

Both Phil and I use Sony Vegas for video editing but there are free tools that will do a good job, VirtualDub is one example and here is a nice tutorial:
http://timelapseblog.com/2009/08/04/...or-time-lapse/

I have not yet tried to make a day-night-day time-lapse because my batteries only last about 3-4 hours. In the Parkes time-lapse I just set it up for night exposures and overexposed about 2 f/stops starting in the twilight. Because of the Moon in the frame the exposure time was considerably shorter (3s) than normally (15s). I can't change the exposure settings once a time-lapse has started without stopping it but this is when Sony Vegas helps with a set of digital transitions to change from one scene to another (like the spiral used in the time-lapse above).

Cheers,
Alex

Thanks Alex.

Does Images Plus enable this sort of work? That way you can control everything from your laptop. Not sure it would enable changing things whilst it is underway unless you stopped quickly changed it and got it going again really quickly like a Formula One car pitstop.

I'll check out that software.

Thanks for sharing your knowledge here Alex. Masterful work.

Sounds like you need a better battery solution. Not that your image is noisy at all but batteries do heat up as they discharge and add thermal noise to DSLRs. The powered false battery setup is preferable and then how you get power to that I am not sure. Perhaps a 12 volt battery and an inverter to 240V from that and the battery/transformer power supply.
It'd last all night with a decent sized battery (deep cycle).

Greg.
