Title: It's... full of stars!
Name: Hristo Velev
Country: Bulgaria
Software: 3ds max, Digital Fusion

An image that I've made for a workshop I'll be presenting in, and to satisfy my long standing desire to do this effect. It will be fun, when I go back to in some day, much better skills and computers! It's done in 3DS Max (PFLow and Afterburn) and Fusion (serious comp). Lots of layers and detail, too bad the smallest got killed in the downsampling to 1600x1200. Still, I think it's not bad - enjoy and crit!

Nice render but there is something wrong with the spiral clouds if it's our milkyway. it does have 2 coming to the center, not just 1 like you are showing.

It's not the milky way, and yes, there are two sleeves, but coming together pretty much in the central bulge, so it's not as visible. Could be better ;) Thanks for the comment.

There's an interesting technique to generate images like the ones from the Hubble telescope.

When the hubble takes images, it takes them in infrared grayscale and many layers are composited using the FITS concatenator plugin for Photoshop to make it colored using the hubble palette.

I was thinking about it, and if you rendered out several render passes in grayscale, then processed the image with FITS using the "hubble palette" it would probably give you results that resembled hubble images.

Although your image is great, it doesn't have the same colors and clarity that hubble images do.
Of course, it wasn't taken by the hubble. But I think using the same process they use for hubble images would bring a render like this to that next level.

My biggest crit is about the colored dust.
The color of the dust is directly dependent on the heat from the star.
So the dust closer to the star will be red.
In your image, the dust is mostly one color, which would mean that there's no change in heat levels from the center to the outer rim, which is simply not possible.
Since the hubble takes infrared grayscale that's how real images like this derive their color, the hubble shows the different heat levels in grayscale based on their heat output, then the photoshop FITS plugin interprets those grayscale values and maps them to an RGB value.

So it would be possible to split the render into layers representing the dust closest to the star(hottest), to the outer layers which are much cooler and therefore more of a blue color.

So if you have several layers like this, you run it through the FITS plugin which will take care of mapping the grayscale values into RGB values.
Then you just need to tweak blending layers and color correct a little.

I've been planning to try this, but I just found out about the FITS plugin last week.

Here's the link to the plugin-http://www.spacetelescope.org/projects/fits_liberator/download_v22.html

nice tribute to Clarke!

good job

(hope it was intended as a tribute! :P)
