- point light source. 1. With respect to angular subtense, a source of light, such as a star, that is very small. In a lab, a point source may be simulated by imaging a large source onto and through a pinhole, or by focusing a parallel bundle of light, such as that from a laser, with a precise lens to a point image. 2.

- In addition, “points” or “lights” do not have to be flashes. You can achieve a multi-point lighting setup by bouncing light off of a v flat or a reflector. The sun can also be a light source. So you can achieve a 2 point lighting or even 3 point lighting setup with …

- This section describes the implementation of a number of them, starting with PointLight, which represents an isotropic point light source that emits the same amount of light in all directions. It is defined in lights/point.h and lights/point.cpp. Figure 12.6 shows a scene rendered with a point light source. Building on this base, a number of more complex lights based on point sources …

- In real world practice a point source will usually still be more than one pixel wide unless the lens is rather exceptional. In this case the light source is not a truly theoretical point source, as it has some minimal width. You are correct that a Foveon type sensor should perform better for this case, but may not be absolutely necessary.
Why is a point light source required for Schlieren Photograph?

- A single bright point source will give good illumination and avoid the problems of smearing out of the image. The requirement for a coherent source of light is pretty universal when you want to produce any form of interference pattern.

- Point Light Source Examples ... But as long as the light source is shaped like the obstruction it will work. Using a auto taillight and a razor blade works because you can align both with care. If making a pinhole you want something around 400 microns which comes out to 0.4mm wide. ... Back to my Schlieren Photography Page. Send me Feedback! ...

- To be fair, there was a light source on the ceiling above the frame, but that was mrely near, not in, the field of view. It is often the case that the source of the flare is a strong light source outside the sensor frame but whose light still impinges on the filter surface and is refracted and then reflected into the part of the signal path ...

- I use DeVere 203 with point light source (similar to what Odyssey- Sales offer with DV504 model). Point lamp 48 watt/6volt from DV504, Rodenstock 120mm condenser set. I use it for 70% of my final prints with my 35mm system (Canon F1N 24/1.4L, 50/1.2L, 85/1.2L). MF and LF negatives have less grain dimension if you consider final print.
