A warmer color temperature (around 2700-3000 Kelvin) can create a cozy and ambient atmosphere, while a cooler color temperature (around 5000-6000 Kelvin) may appear brighter and more suitable for task lighting. When comparing LED bulbs to other types of bulbs, it’s crucial to consider their...
Despite being so hot, the corona is less than a millionth as bright as the Sun. As you walk away from a bonfire, you feel less of its heat because you receive less energy due to the inverse square law. Why is the more distant corona so much hotter than parts of the Sun closer to...
Color temperature describes the “color” of white light by a light source radiated by a perfect black body at a given temperature measured in degrees Kelvin. Yeah, that's a mouthful. You'll understand color temperature better if you've ever changed a light bulb at home and noticed that it...
Kelvin settings: this enables you to manually set colour temperatures in Kelvin from 2500K up to 10,000K in 100K increments. While Auto White Balance (AWB) is convenient, it is not always accurate and is prone to colour shifts, especially under mixed light sources. For the best results, p...
Kelvin Lights will have Kelvin rating, which is a unit of measure for temperature and is commonly used to describe the type of light one can expect toseefrom a light fixture and is loosely connected to the light energy in Nanometers. ...

The color temperature of a light bulb can significantly affect the ambiance of a room. It is measured in Kelvin (K). Warm White (2700K-3000K) Creates a cozy and relaxing atmosphere. Ideal for living areas and bedrooms where a softer light is preferred. ...
The dead star—which is currently not bright enough to appear in the sky—is one of a pair that orbit each other in a binary system called T Coronae Borealis, or T CrB. Known as awhite dwarf, this leftover stellar core is snatching material from its ...
To adjust the bright light, you must employ Spot Metering. So, if your device supports this function, be sure to practice with it. However, if there is no such function, you can use Partial Metering. While taking sun flare photos, I often use autofocus, trying to adjust it to the subj...
