The site will remain active until April 10, and the editorial team is still working on reviews and looking forward to delivering some of our best-ever content.
Everyone on our staff was a reader and fan of DPReview before working here, and we’re grateful for the communities that formed around the site.Thank you for your support over the years, and we hope you’ll join us in the coming weeks as we celebrate this journey.
Sincerely,
Scott Everett
General Manager – DPReview.com

“Not every light performs the same way. Lights and lighting are tricky to handle. You have to plan for every circumstance. But the good news is, lighting can be adjusted. Let’s look at different factors that affect lighting in every scene you shoot. “
Use CRI, Luminous Efficacy and color temperature controls to match your needs.
Color Temperature
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 Kelvinhttps://www.pixelsham.com/2019/10/18/color-temperature/
CRI
“The Color Rendering Index is a measurement of how faithfully a light source reveals the colors of whatever it illuminates, it describes the ability of a light source to reveal the color of an object, as compared to the color a natural light source would provide. The highest possible CRI is 100. A CRI of 100 generally refers to a perfect black body, like a tungsten light source or the sun. “https://www.studiobinder.com/blog/what-is-color-rendering-index

The most common use of polarized technology is to reduce lighting complexity on the subject.

Details such as glare and hard edges are not removed, but greatly reduced.
