I wish to be able to have
- green/purple
- blue/violet
fringes be directly rendered via maxwell.

such as seen in those two pics (source : http://powerretouche.com/Color-fringe_tutorial.htm ) :




As far as I've heard once a few years ago, the blue/violet type of fringe is produced by an 'electrical' error directly on the sensor chip / ccd. Not sure though. The other type (green/purple) is created via chromatic aberration.

Many peeps are already adding this effect as a POST effect, e.g. via PhotoShop's 'lens correction' filter, but I wish to be able to render it. Makes Maxwell rendered pics look even more realistic.

Funny, photographers want to reduce the effect, and we want to put it back in. LOL

hehe.

and others loop this in/out 100 times and call it 'art'.

Well one thing that has bothered me... well not quite exactly bothered but rather makes me wonder about... is that Maxwell is suppose to make real images of the world by mimicking a camera.
Cameras are in turn trying to mimic the human eye which is what we use to see the world. Unless you're a robot
So in short, Maxwell is trying to mimic another thing that is mimicking the eye that sees the world.

I wonder why there are some limitations put into Maxwell deliberately while camera production companies are trying with their $$$ to overcome them.
Don't get me wrong, I like some of those effects But I wish there could be an option of less mimicking too.


Maybe Maxwell is trying to mimic a mimic of the world?
And [insert biased renderer] is trying to mimic a mimic a mimic of the world

well sorry for the off topic, but I find that interesting to your quote

Aji, I have often considered the same thing -- particularly on the topic of perspective. I take care now to use "normal" perspective (that is as close to how our eye sees) whenever possible for just this reason.

Obviously it's nice to have the option to set it whatever we like for dramatic effect, but I do find the extreme examples of it often distracting in many architectural renders I see.

On topic, have you tried the free motiva solution for this effect (http://www.motivacg.com/descargas_en.php) -- it works really well.

Best,
Jason.

...I take care now to use "normal" perspective (that is as close to how our eye sees) whenever possible for just this reason...

I try to do that as well some times

...Obviously it's nice to have the option to set it whatever we like for dramatic effect, but I do find the extreme examples of it often distracting in many architectural renders I see...

The way I like to work with photos is that I always go for lossless compression during photoshoping but only in the end "save for the web" with desired lossy compression, like everyone else does I guess...

That's the analogy for me with rendering. I try to render as real and unbiased as possible with Maxwell, like editing photos lossless in Photoshop.
Then at the end I do the "lossy effects", like toon shading etc. and like you do with camera effects. That's like the analogy of lossy photo compression after editing


On topic:
Can't believe motiva realcamera is actually free, good link mate!

that's exactly the point : to create photorealistic pictures without the need for a lot of additional post work.

though maxwell render is not [and should never !] be 'limited' per se to arch viz work.

[this is the same reason why rendering ambient occlusion should also be possible in maxwell, especially if you think of it just as an additional 'texture'.]

the wish list is endless, I know, I just wanted to add this to the queue.
