Viewing 3D
Finnish-Suomeksi
Nähdäksesi anaglyph 3D-kuviani tarvitset Puna-Sinilasit!
Ne ovat yleensä erittäin edullisia, 1-2€, ja helposti ostettavissa onlinemyymälöistä.
Suomessa laseja voi ostaa ainakin täältä:

HUOM!
Lasien linssien täytyy olla PUNAINEN ja SINININEN, jotta kuvat näkyisivät oikein.

To see my anaglyph Red/Cyan 3D-images, you'll need a right kind of 3D-eyeglasses!
They are usually very inexpensive and can be bought online easily.
Here are few links:
USA, http://www.berezin.com/3D/3dglasses.htm
There is many online sellers for 3D-glasses, google them down to find a suitable seller in you area.
EDIT. Finnish only, sorry!
Huomasin juuri, että samassa Suomalaisessa verkkokaupassa, jossa myydään 3D-laseja, on myynnissä 9€ hintainen stereokuvien katselulaite:
http://www.elektroni.fi/?product=5452
Ko. laitteella voi katsella stereopari-paerikuvia 3D-muodossa!
Täältä voi tilata stereoparikuviani valokuvina: http://astroanarchy.zenfolio.com/p272573124

Hinta 1,95€ kappale, vähän isompi koko, joka vielä toimii, 3,95€
Katselulaitteen kanssa siis toimivat vain "parallel vision" tekniikalla katseltavat kuvat.

In my Blog, there is many anaglyph movies too:
Blogissani on useita anaglyph 3D elokuvaklippejä:

HOW?
I have been asked many times, how my 3D-images are done, so here it goes!

HOW?
I have been asked many times, how my 3D-images are done, so here it goes!
All the original 2D-images are imaged by me.
Due the huge distances, no real parallax can be imaged to form a volumetric information.
I have developed a method to turn any 2D-astronomical image to a various 3D-formats. The result is always approximation of the reality, based on some known facts and an artistic impression.
What are the known facts?
By using a scientifically estimated distance of the object, I can organize right amount of stars front and behind the object.
(as then we know the absolute position of an object at our Milky-way)
There usually is a known star cluster or a star(s) coursing the ionization and stars can be placed in right relative position to the nebula itself .
Stars are divided to groups by apparent brightness, that can be used as a draft distance indicator, brighter the closer.
The nebula itself is emitting its own light, when ionized, typical to each element.
The thickness of the nebula can be estimated by its brightness.
Many other relative distances can be figured out just carefully studying the image, like dark nebulae must be front of bright ones.
The local stellar wind, radiation pressure, from the star cluster shapes the nebulae, pillar like formations must then point to a cluster for that reason.
Same radiation pressure usually forms kind of cavitation hole at the nebulosa, around the star cluster, by blowing away all the gas around it.

Many other small indicators can be found from the image itself.
The artistic part is then mixed to a scientific part, rest is very much like a sculpting.
I have published a, little simplified, step by step tutorial about turning astronomical images to a 3D-stereo pairs under a PhotoShop. It can be found from here as a PDF: astroanarchy.blogspot.com/2009/04/neaic.html
WHY?
Firstly, they are great fun to do. Secondly, because I can.
3D-experiments seems to increase a public interest to a subject, as you might have noticed.
Personally, I have studied my astronomical images much deeper, than ever without 3D-modeling.
The 3D-studies have really add a new dimension to my hobby as an astronomical photographer. (pun intended)

You'll need Red/Cyan Eyeglasses to be able to see this image right.
Note, if you have a Red and Blue filters, you can use them! Red goes to Left eye.
