We've pointed out numerous times that staring at bright screens such as tablets or laptops in bed has a bad effect on your sleep patterns and your overall health. Now one study hints at an possible link between regular exposure to artificial light and levels of depression.
An important part of taking great photos or shooting great video is paying attention to your lighting. It can be frustrating when you're shooting indoors and there just isn't enough light for the job. Instead of struggling with desk lamps, this DIY strip light uses a heavy-duty power strip, a bunch of compact fluorescents (CFLs) and an umbrella stand to create a portable strip light that packs enough lux for photography, shooting video, or just some task lighting in the garage.
Becoming a good photographer requires several things, and one of the hardest to learn is lighting. Virtual Lighting Studio is a free web app that lets you light a (pretty awkward) subject with up to six lights so you can see how each setup affects the image. Because lighting is one of those things that you learn best by practice, this is possibly the easiest way to understand what different arrangements can do for your image.
We've previously looked at some great ways to achieve ambient lighting with and without rope lighting. If you have some to spare, consider running them underneath your kitchen or bathroom cabinets or island to make sure you never stub your toe in the middle of the night again.
Instructables user scraptopower designed a thermoelectric lamp that can convert heat into small amounts of electricity. One of the best uses for this is building an LED lamp that runs from tea candles.
Most ambient lights and sensors are designed to generate light to even out the picture on the front of the panel and reduce any light bleed from the back of an LCD display. This Arduino-powered Shiftbrite LED ambilight setup takes things a step further by automatically adjusting the colour and intensity of the ambient lights on the back of the display to match whatever is on-screen. Plus, it's pretty easy on the eyes.
The video above shows how a man in an impoverished urban area in the Philippines created a solar light to brighten the densely packed windowless homes that are dark inside even when the sun is shining brightly. The method involves making a roof cutout to support the bottle and filling the bottle with water and a little bleach.
