I've update whole objectives assembly with new Ray Portal as a Camera's sensor, this change improved a little bit even the rendering time. first row #Zeiss Tessar, and second Row H. #Zollner #Tessar, both with new Sensor. Now I would need a bit of experience with photography to do better, some example photos with these lenses and a bit of technique would help me improve further. #optic #lenses #3d #B3D #Blender3d #Blender

I don't know what I did but now with the ray portal I can visualize a strange phenomenon of light rays passing through the various #optic #lenses of the objective assembly,but I compromised the previous node which I can no longer reproduce. #b3d #Blender3D #Blender

Today after random attempts, because in reality I still haven't fully understood how it works, I implemented a Ray Portal as a sensor, and this with random values ​​allowed me to correct the angle and expand the field of vision of the lenses, previously some were too narrow and to frame the whole scene you have to move the camera a few kilometers away. Same camera with Ray portal and not and the difference is evident. #optic #blender3d #Blender #lens

I have made a simple video which highlights the differences between rendering with or without chromatic aberration. this method is better than #Blender composting that deform the images. and with #3D #lenses there are not diffraction changes. #b3d #Blender3d #optic

Tomorrow I will try to finish this old Pixar scene, and I will try to do some rendering test with some of the 3D lenses I created, but already from these tests without doing much, I would say that the difference is noticeable. :) #b3d #Blender #Blender3D #optic #lens #3d

Chromatic aberration, without composting only with physical 3D #optic #lenses. #b3d #Blender3D #Blender

Heck in the end the best of all is the simple one, I tried all the known dispersion methods, lots of nodes, but the one that comes closest to the photos is to use three different IORs with 3 diffraction materials red green and blue. #b3d #Blender #Blender3D #optic #lens #3D

Now the dispersion is better, I will look for a way to implement the chromatic aberration of the #lenses using the actual values ​​for the lenses, but it will not be easy, to do it, I have to find a solution for the brightness. #3D #optic #b3d #Blender3D #Cycles

I'm doing some checks by comparing the 3D #optical #lenses, but it seems to me that #Blender's f-Stop values, in addition to having scale problems, in this case the model of the Fiat 500 is in meters and OK, however #b3d's camera it has an incorrect F-Stop value. Left side b3d all with f/Stop is 0.2, others with 3D lenses are more realistic one with f/Stop at 8 and other to 18.0 Camera 35mm and 100mm #optic #lens #photo #3d

I found an interesting web about Paul Rudolph and his #optic #lenses design, one of the pioneer of #photographic objectives. I want to make those patents https://zeissikonveb.de/start/geschichte/personen/paul-rudolph.html

Old #lenses are always excellent, especially those created by pioneers such as Rudolph Paul who created the lenses for #Zeiss. #b3d #Blender #Blender3D #optic #lenses #3D
