Indigo 1.0.4

[Kram1032]

for dirt => for blurrier lines and imperfections on the lens^^ (and I think, the lensshape itself also gets controlled by this )

Just try to set a very high f-stop

[Anthony]

High F-Stop gets a bigger blur, but I am not getting big streaks coming out the side. Is it cause Im using a blackbody emitter or maybe I just need to do more experiments

I wont bother witht he obstacle map then

[Kram1032]

hi f-stop should make things sharper. But it also should give more bloom.

those "big streaks" aren't too realistic in most cases

Did anyone yet try to film the sun?

Yes, first thing I did. Actually my diffraction map was unadapted and that was not pretty; the square shape of the map was visible. Of course now I have a better idea on how diffraction map should look

Basically shoting the sun works good.

[Kram1032]

great
Maybe, I still have my amethyst scene, somewhere... Would be great to redo it (maybe even in combination with the atmosphere... The light comes much smoother, then, so there should be a visible difference... And I think, I used full diffuse gold (exponent 0 with au.nk) as a mat and it was a not-energy-loss-compensated version, so, it might also look a lot brighter....)

I just thought I've to post this, for people that are not that familiar with
photography at all. More stuff can be found on photographertips.net.



From "Understanding Aperture" - Have fun! ;o))

* added aperture_diffraction toggle in infile.

In case anyone was wondering, this can be over-ridden by adding

Code: Select all

<aperture_diffraction>false</aperture_diffraction>

in the render settings element. I don't think this has been explicitly mentioned anywhere.

Nice work, Ono! I was a bit confused about obstacle maps at first. Maybe you could post the obstacle map that you used to produce the second glare pattern. 'diffraction_test.igs' does not produce the same glare pattern that you have shown in your first post. I suppose this is due to the lack of obstacle map.

[OnoSendai]

Well this is the combination of aperture + obstacle.
It's the regular nature of the obstacle grid that gives the distinctive glare pattern.

[Kram1032]

if you have a fully white picture, will Indigo interpret this as a perfectly squared aperture at maximum size?

[CTZn]

Fixed, I think. 1.0.4 was running in 1.0.2 folder, I believe that's because I declared msvc dll's from 1.0.2 folder in system path.

I keep having an error, "key 'aperture_diffraction' is not in the map". I've set it to circular, and neither am I using an obstacle map.

Maybe that helps:

Thanks

a bit late to the party - but nixe!

maybe time to dust the cobwebs off my Indigo directory and fire her up

"I keep having an error, "key 'aperture_diffraction' is not in the map". I've set it to circular, and neither am I using an obstacle map."

Because you are rendering with the .ini of v1.0.2! That's the point.

Bwahaha

Edit: never too late when there is a party

[CoolColJ]

only problem with having bloom as part of the render process, is that your stuck with it....

or is it a tonemapping thing like the Camera Responce?

[CTZn]

Sorry that's me again, but upon first test I had the impression that it was pretty much sensible to burn value, easy to set isn't it ? But that need further investigating.
