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.

How to divide stage lighting?

Most lighting pros will divide their stages into zones of 8-12 foot diameter circles with a slight overlap of zones to make sure there are no holes in the coverage. If your stage is 30 feet wide and 30 feet deep, you would likely end up with 3 zones across down-stage, 3 zones across mid-stage, and 3 zones across up-stage. Breaking your stage into these zones not only helps make lighting them evenly more manageable but also allows for greater control of special lighting. For example, perhaps you want to draw attention to a speaker down-stage left for one part of your service and then immediately cut to down-stage right for the next part. By lighting each zone individually at the right times, you draw everyone’s attention to the right place at the right time.

How to light a stage with no lights?

This may take some experimentation, but if you’re starting out with no lights (and no video cameras), I’d say start off with two or three point lighting for every zone on your stage. Work the angles the best you can. If you have to fudge three point lighting at 40 degrees off center instead of 45 degrees or have your single front light in two point lighting be slightly off center, it’s not the end of the world as long as it looks good to you and puts focus where it needs to be. In fact if you only have two fixtures per zone and choose to have a flatter look but less shadows, you can use two fixtures from 45 degrees off center from the front, creating a more even front look.

Is one point lighting good for nature?

In many occasions, a single source of light creates a very natural, sometimes dramatic look that will draw people’s attention to the single lighted person or surface. And if it’s good enough for nature, there are times it might be good enough for you. The catch? As anyone can see with a walk around the park, a single source looks two dimensional or flat, and rarely hits people straight on, so it creates shadows.

Softbox Lighting Kit

The softbox lighting kit from CowboyStudio on Amazon has proven to be a winner…but are you wondering what a softbox actually is all about? Essentially, a softbox adds brightness while using a filter on the front to reduce less-than-attractive shadows.

Daylight Fluorescent Video Light

As you'll see in my lighting guide and in the video, I do use one of my softboxes without the front filter. It adds just a burst of light right in the background, right where I need it. No shadows here, thank you very much!

Ring Light

The world changed the day the ring light was invented. Okay, so maybe I'm a little dramatic, but it certainly made us all look better! I chose this ring light, again from Amazon, and have been really happy with it. It's large enough that it places light exactly where I need it most and it's easy to use.

Webcam

And…remember the “LIGHTS, CAMERA” part of the movie-making magic I mentioned above? Well, I also picked up a camera that perches on my computer for filming. (For less than fifty bucks!) I've been using this handy little Logitech for quite a long time, and have no complaints.

What is a 4 point inspection?

What is the 4 point system for fabric inspection?

It is a tool for satisfying internal as well as external customer. In this fabric inspection system, the number of defect points in one hundred square yards of fabrics is determined through inspection. If the defect points in each one hundred square yards of fabrics be 40 or above, then that fabric will be considered as rejected. Based on the price and quality of garments, the acceptability of defect points may be determined more than 40 also, but in that case it depends on the understanding of the buyer and the seller. The chart of point determination for the defects in fabrics is given below:

What is PDLS headlights?

Porsche ’s top performers also have Porsche Dynamic Light System (PDLS) Plus, headlights that feature nearly everything: dynamic range control, adverse weather function, and a camera-based system that adjusts light distribution. The High Beam Assistant detects oncoming traffic and automatically dims the lights. The Intersection Assistant activates the left and right indicators, which broadens the cone of light and provides greater illumination of the area directly around the vehicle. In other words, PDLS stands for little high-tech jewels.

What happens if one of the light modules goes out?

If just one of the light modules goes out, the regulations require that it be replaced immediately, so intelligent cooling and mounting systems have been designed to prevent this. The entire concept is Porsche Intelligent Performance in action—extremely lightweight, extremely robust, and extremely bright.

Why do race cars need a searchlight?

As Martin Kaussen from the racing development department explains, “It has to shine as brightly as a searchlight from start to finish, by day and by night .” The guiding premise is to keep it simple. To illuminate a racetrack without oncoming traffic in the best possible way, two main beams and two pencil beams were developed. As Kaussen notes, “We don’t need any low beams or daytime running lights; we need full, far-reaching light that doesn’t blind the cars in front and helps show them the direction to take when moving out of the way.”

  • When you want the subtleness of a single light source but want your people to stand out in 3D, two-point lighting can be a great way to add dimensionality without going overboard on your lighting.

Three-Point Lighting

  • Not everyone is happy with the shadows that two-point lighting can produce, so the logical solution would be to add two light fixtures from the front, still 30-40 degrees up but having each fixture hitting your zone from 45 degree angles off center. Add that same top light from above and slightly behind, and you’ve got three fixtures giving you light on both sides of the face (regardles…
