An experimental 3D-animation of the Pelican Nebula
Since the Weather doesn't support new images, I'm publishing some experimental work here.
I have tested a new method to publish my 3D-images as a form of Lenticular prints.
For this technique to work, I need series of images from different angles, in this case 24 images are needed.
Lenticular printing is actually an old technique but in past few years it has become much more sophisticated.
The results can be stunning visually, image plane disappears and object floats in and outside of the frame.
Since astronomical objects are too far away, no real parallax can be imaged. Doe to that, I have developed a method to turn my images to various 3D-formats. My work flow is based on scientific data from the object, distance and the source of ionization are usually known. The different types of the nebulae has typical structures, pillar like formations must point to the source of ionization, the radiation pressure forms kind of hollow area, inside of the nebula, around newly born stars, dark nebulae must be at front of the emission ones to show, etc... rest of the missing information is then replaced with an artistic vision.
The whole process is pretty much like sculpting!

The Pelican Nebula in Cygnus as an animation
Only real elements from the original 2D-image are used for the animation
NOTE! Let the animation load, ~7MB
This is a personal vision about forms and shapes, based on some known facts and an artistic impression.

PS.
Here are other 3D-formats out of the same material
Stereopairs
For Parallel vision method
For Cross vision method

You'll need Red/Cyan eyeglasses to see this image as 3D.

Lagoon Nebula, Messier 8, as an animation
NOTE. Only real data from the original 2D-image is used for the 3D-animation!
Generally images about space objects shows them flat as a paintings in a canvas but in reality, they are volumes floating in three dimensional space. The purpose of my work is to show how I personally see those distant objects in my mind and they are fun to do!
The accuracy of the model depends how well I have known, figured out and guessed. Right or wrong, if my 3D experiments are giving something to think, they are working well.

Happy Halloween
A ghostly figure from deep space, IC 63
Happy Halloween!
I originally shot this target at Halloween night of the year 2010.
I didn't plan to shoot a seasonal theme image, just followed my imaging plan. When the image first time appeared in my screen at Halloween night, I felt cold fingers at my back...
Original image and the imaging data can be seen here:

I want to know
I WANT TO KNOW
I get inspired by a poster, seen in TV-series X-files.
(Mulder's poster hangs in the wall of X-files basement office.)
It turned out, that it was made just for the TV-series by the production team.
Images used in the "I want to know" poster above are shot by me.
