Description

I've had a good play around with raytracing and eventually figured out how to make the bubbles look more realistic. The second image here has had auto-levels done in Photoshop, but I can't decide which one looks better - what do you think? My next stage will be to try to animate a bubble popping.

INMHO, the second one's better. Great bubbles! I also like the focus work, although the background could use a little more work.

Way cool. If you get those bubbles to pop PLEASE let me know, because that is something that I'd love to see!!

Good stuff Verity. I agree with sedlity. It needs some rainbowie stuff happening. Cool.

Thanks everyone for your comments - interestingly enough, in the research I did before I started this project, I discovered a couple of things -

bubbles always form into a perfect sphere, with no irregularities even if blown out of an irregular shape like a star; and
The spectrum refractions on the surfaces of bubbles are only visible in certain situations, dependent mostly on lighting, and somewhat on what's included in the bubble mix.

I was aiming to meet the scientific requirements of bubbles here, as opposed to our perception of what bubbles look like. Hope this clears up the confusion.

Bubbles will always move towards the perfect sphere... That is the most stable state, but environm,ental conditions (eg wind, etc) will typically reseult in small, temporary deviations from the ideal. A field of perfectly spherical bubbles looks a little bit unnatural, that's all. Also, typical soap bubble usually do have some chromatic residue. Your attempt to be scientific may have resulted in an image that the observer intuitively perceives as unnatural. This isn't confusion--it is a matter of winning the battle and losing the war.

Sedulity, I can see your point about perception vs reality. The question then becomes - how do we figure out what the more general perception is in any given situation? Have you noticed how sometimes the feedback we get from various people on our images is completely a series of contradictions?
