After trying to do a NeatImage Noise Profile for Indigo, I found something strange
about the way Indigo works with light Temperature...
I used the following Script to get a fully illuminated Plane:
Code: Select all
<scene> <renderer_settings> <width>480</width> <height>480</height> </renderer_settings> <background> <spectrum> <blackbody> <temperature>6500</temperature> <gain>1.0</gain> </blackbody> </spectrum> </background> <camera> <!--Global Pos/Size Multiplier: 0.010000--> <pos>0 0 22</pos> <up>0 0 0</up> <forwards>0 0 -1</forwards> <aperture_radius>0.001</aperture_radius> <focus_distance>22</focus_distance> <sensor_width>0.036</sensor_width> <lens_sensor_dist>0.1</lens_sensor_dist> <aspect_ratio>1</aspect_ratio> <white_balance>D65</white_balance> </camera> <!-- Ground Material --> <material> <name>ground</name> <diffuse> <colour>1 1 1</colour> </diffuse> </material> <!-- Ground Plane --> <plane> <normal>0 0 1</normal> <dist>0</dist> <material_name>ground</material_name> </plane> </scene>
I get the following result:
You can perhaps see with your eyes, that this Pic is "red", Photoshop tells me:
So it seems that there is more red than blue in the picture, and even less Green!!! Why??
After this I raised the contrast to +100 to see better what is inside this "light red Plane"
I got the following very interesting result:
It seems that the most "color" is on the edges, still some kind of vignetting,
but why is this vignetting not even with a aspect Ratio of 1 ???
And why are there "Vigneting lines" at the left and right side...
Perhapes somedody who knows better about Cameras could tell me if
my camera settings are the reason why some of this stuff happens!
I try to raise the "lens_sensor_dist" to maximum, and check the result!
