Hi, here is an image I did last weekend (2of5)http://www.motionblurstudio.com/WIP/Microscopy/micro2.jpg

wow, no replies... That bad?

nah not bad, just the subject is a little weird. The focus effects are good though, the models are a little strange I guess.

Something about it seems....artificialll...I can't put my finger on it. Perhaps the color combination or something to that extent. I'd like to see more blue things in the background, the the one in the foreground is the leader of the pack.

I would love to know how you make the edges of the objects glow like that.

Is it a gradient on the luminosity channel or somehthing like that?

He might be using transparent edges?

The "transparent" edges is all done by digital confusion. The subject is polen. Sunflower polen to be more precise. It isn't a 100% replica but I guess it is close enough to the real thing. I wish I had more time to work on the images, the blue thing's spikes (polen) should be bluer towards the top, to achieve that I have to use a weight map... maybe I'll revise it.

Well, it looks like you're mimicking a false color scanning electron microscopy (SEM) image. First let me say I like it, but being a materials chemist and a LWer I might be able to give some advice on this. I've done a lot of electron microscopy in my days, and the big advantage of EM is that there is virtually no depth of field. Even with a sample stage at an extreme tilt, everything you can see is in focus. That's reality though and this is your rendering so, its all good. I do think your DOF looks a bit messy though. Here's a couple of false colored SEMs from my past research, just for fun (not LW in any way).

Keep up with the science (and sci fi) images. I try to use LW any time I can for visualization in chemistry. Hopefully in the future I'll post some cool molecular modeling stuff I've been working on

So that is what transparent edges do. I have seen the option before in the shaders menu. I think it is called edge transparency. Does this option give you the same effect as the "transparent edges" in digital confusion?

Not really. The "transparent" edges is produced by the camera apperture and f-stop settings in digital confussion, just make sure you deselect "render background geometry". Edge transparency in the Advanced tab in the surfacing editor doesn't need DOF info. The manual explains this much better than I possibly could.

BTW I wasn't really trying to replicate an electron microscope...;)
here are more images... the neuron was inspired by "A Body Story"

Thanks for the explanation. I really like these new images, especially the top one. Are you doing them for your portfolio, or just for exploration?
