6.60 samples per pixel.

Sorry for the constant rework of 5 or 6 scenes, I need this workflow for contrast the evolution of the camera and to fix a lot of things. More over I will proyect some things more...

40 min. 16 samples per pixel.
If the value of the luxes to light the scene are too high there are some problems in my scenes, specially if there are mixed with the atmospheric simulation...

Now I want to center my attention in the cathedral, slowly...

One more comparative (erasing precedent trails...).

Seems that I need now to adjust again the IOR of the glasses to improve the perspective and balance again the photographies... About color expression.... the real tabulated spectrums are great even they are invented.

I got a perfect perspective.
Need to work a little more the focusing plane (is good at this moment...).
Perspective.gif
Curiosly, for a good perspective, this objective needs a modify Canon EF M (mirrorless, not reflex).
For an Canon EF I got aberrations in perspective.
Take in account that this is a "full frame photograph" (square format with a film of 22.1 milimeters, Canon APS-C).
Other formats are easier to trick.
Double diaphragm plus dichroic filter.
Super slow at this point...

Processual document.
Optics magnify first planes at short focus planes (45 cm in this case). Cathedral has 45 meters...
Superposition processual document.jpg
The plate and the knife are free simple models from internet (time, obviously I don´t like).
I model with a voxel program the seeds years ago, the rest of the work is done with Xfrog (phylotaxys) and cinema cloner (like).
The displacement map of the silver seeds is conceptual (like).
The human blood has a real tabulated spectrum from database adapted and based in hemoglobine (like).
The table is super fake... don´t know what to do with this...
The scene is enclosed in a small blind room.
The two softboxes are simple, but the screens has thicknes, the lights are not a plane but meshes, the difusse transmitter has a medium...

I try to naturalize as much as possible, but what is a polygon?

More over I will work the scene further with my own models a glass and some minor things, ... (hope...)

Just calibrating and testing... still ... .... :)

If I compense the focus plane I lost the correct perspective.
Maybe I crop a little the film and is OK. But, the focus plane change for every distance, ...
Is not possible to compensate the camera much more...
Is an approximation.

Some latest test. 8-15 hours.

A polygon is an approximative intermediary that actually works well.
I speak of another thing, don´t know well...

32-64 spp.
Let´s go to represent the union elements (difficult)...
The perspective of the camera is right. Still some things under investigation...

I'm feeling that this cathedral is a fantastic place to be born... I'm not going to represent it, but in the center of the site there should be delivery rooms ("swimming pools", etc, ...). Only a feeling...

Three perspectives more. In love.
8-16 spp.
Look at the cenital one, black.

Double diaphragm:
-First between external and middle groups, F-stop 0.5.
-Second between middle and internal groups, F-stop 2.

Deep vignetting.
Dichroic filter under investigation, seems that 1 milimeter thickness is not enough, maybe I raise the absorption of the dichroic material (and some variations...).

I learned that certain lost of peripherical focus is super cool. IN. But in fact is super difficult to obtain a completely stable plane of focus for an approximation... (F-stop 16-24).
