Description
I saw the light hitting one of my lens filters so i thought i might have a little play with light. I like how the glass changes depending on the angle of the light source, and i thought maybe someone else would too
Modelled & rendered in C4D, post work in Photoshop.
Full size 1920x1200, available via download link.

This is a really good render. It's very photographic, but more "perfect" than most photographs can get.
And you said your 350D can't get 40" prints? I have a nikon D80, which is right now only two steps up from the entry-level SLR and it seems to compare to the 350D pretty well. I can get 40", and even bigger in RAW.

thanks, im glad you like it. ive tried roughing things up a bit so that they look less realistic, but i think i actually prefer things being more smooth. thanks for the fave too
well, if i use a fractal scaler and a very low dpi i could squeeze out a print from one of my photos, but it just doesnt have the resolution to create stuff thats high enough quality for my liking (whereas with 3d i can render to any size). the pics are 3072x2040 pixels and the 300d (dunno why i keep thinking i have the 350) isnt good at reducing noise in all but the brightest conditions, so they just dont look that good scaled up. anyway, im a mediocre photographer at best so it doesnt really matter.

No problem! The biggest JPEG my camera generates is around 3700x2500 which you could possibly squeeze a 40" from, but in RAW it'll produce around 4000x5300 which would be fine. So I just read the 300D is an older camera... that explains your low res. Well at least you're good at renders!

yea the 300d was the first non-pro digital slr so its got its shortcomings. 3d stuff is a godsend if you need huge images and its let me put up most of my prints at the biggest sizes at 300dpi, which makes them look incredibly crisp.

Understandable. I really want to get into 3D rendering, the results always look so smooth. I just don't have the money for the resources I'd need.

yea the cost can be a problem. its good that there are now pretty powerful free 3d apps such as blender, but the hardware is still a problem unless you enjoy waiting days for things to finish.

Yeah, actually running the software really poses a problem on my non-supercomputer G4.

i use cinema4d on my laptop (1ghz g4 pb) when im not at home and i can work on scenes in it without any problems, it just renders too slowly to be useful for anything large. if youve got 64 megs of vram and a gig of ram then that should be enough to work in c4d, if not to get any pics out at print resolution.

Strangely pleasing and hypnotic, but where are the colours?

yea i experimented with some colours but they all made it look a bit garish and not as calming as i wanted. im considering rendering a version with different colours for each lens but i dont yet know how thatll turn out. this thing takes 6.5 hours to render at print res and i cant be bothered with doing high quality low res renders (which take half an hour to 45 mins)if the finals gonna be up as a print anyway. ive gotta render ricebowl out for print res and then hopefully i can leave the colour version of this going overnight.

I was referring more to light spectrum colours from the lenses, they usually put out something don't they? Even if it's only a faint purple haze.

oh, thats chromatic abberation i think. thats something i dont know how to achieve in c4d, and it might not even be possible without texture mapping it on because the light photons are just one colour rather than 3. passing light through a prism doesnt split it into the other colours either. technically, the abberation is a bad thing so a lot of modern lenses dont do it anymore. just pretend these are cutting edge apochromatic ones..

ah shut up
id need to make a texture of at least 2000x2000 pixels to make it look decent at print res and photoshop would have me die of old age before agreeing to create that without crashing every 30 secs. perhaps some day maxon will add true light to the caustics thing but i dont see it happening myself.

Just spend money on some real lens elements and take a photo.

unfortunately thatd require me also spending money on backing paper and/or a lightbox, a load of lights that arent yellow, and a whole new camera cos the 350d doesnt have enough pixels to do the nice 40" prints. thats money im afraid i dont have, so im tending to take photos as reference material now and then recreating them in 3d. probably should be the other way round, but needs must. that reminds me, i should submit a scrap of the pic with the red pills..
