Here is a short manual relating iso, aperture and shutter speed to Lighting Conditions:

This is pretty old, but as far as I can remember I couldn't get better results that those in this thread. Others may have gotten better results.

I don't know. Where did you get that number? But making an iq test for the brightest man on the planet is going to be difficult--who is going to construct the test?

There are several tests that measure iq and the number does not mean much unless the test it is related to is also given. So 132 in Stanford-Binet is the same as 148 in Catell. Stanford-Binet is probably the more common, but it is easy to "boost" one's intelligence score by converting it to catell a...

Here are a sample of values:

I would love to see an animation of this, with the ripples moving!

I was wrong about the movement of the screen: If objects are closer to the camera than infinity then move the screen away from the lens.

So objects @ infinity -> screen @ 48.5 mm
... objects @ 5 m -> screen @ 50 mm (perhaps, i don't know exactly)

The screen must be moved by 1.5 mm closer to the front to focus at infinity, and the a little closer for objects closer than that. Why did you put the screen in that position then if its not focussed on anything there? Or is it focussing on everything that is even further than infinitely away? ;-) ...

I'm currently testing the lens model and I can't get it to focus no mather what i do. Any more tips ryjo ? If the object is closer to the lens, then i have to move the white plane closer to Indigo camera? I went almost all the way to indigo cam, but no changes in output image. Also, what's that big...

It's reversed because the indigo camera is taking a photo of a projected image and not of the objects them selves (which is what a camera normally do).

This is like being inside a camera obscura and taking a photo of the projected image.

This is another result of using the simulated camera. The cleaner image is the reference pic (rendered with indigo camera only).

The "simulated camera" image is left/right-flipped.

Time: 20h / image.

The model is the sponza atrium.

:( Great....but I don't understand how you use your lens project instead the camera in Blender for example!! Can you explain me please!! Hi, I don't use Blender, but I'll try to explain how to set up set camera: The indigo camera is placed inside the modeled camera and is pointed towards the rear e...

wow. your modelling must be somewhat more accurate than mine. :) good work Thanks! I think your result were as good, and my scene isn't very interesting. It would be nice to see a real scene 'shot' with a modeled camera and see if it looks different, or more realistic (as a photo). I have attached ...

Wow, that's amazing! I never managed to get a decent image out of it. How hard was it to alight the lenses? I could never get the focal point right (I think) with simple lenses, so decided not to go for the cooke triplet. Hi, The way I did it was to take an image of the design and then reconstruct ...

This is the latest entry from the log: Time elapsed: 47h, 32m, 3s Done 9932600000.00000 samples (18393.70370 samples per pixel) 58043.58855 samples / second (17.22843 micro-seconds / sample) Shutting down... :roll: But it looked pretty ok after about 10 h. In order to set the focus I moved the image...
