A reason why we made Lightsynth

Via this image, We can describe the key concept of Lightsynth to our users.

A Good Example 1: Dark Indoor + Sunny Outdoor

Needless to say, we can see the outdoor sky from the darken indoor! This comparison tells Lightsynth can be useful under tricky exposure condition.

A Good Example 2: Outdoor + Stark Contrast

The bright area on the top of this image, the sky is almost maintained with correct exposure, but for the bottom, the tone range and shadow detail of dark area significantly improved. So our users can understand when they should use Lightsynth, and a reason why use.

The Best Example: A Report For Wrong White Balance

Yeah, Our users can think, oh, it’s bad! But, first and foremost, such a report is very valuable information of its lighting situations, so essentially can help us to rapidly improve the quality of Lightsynth. Always welcome and thank you for your report!

A Not-So-Good Example 1: Just Brightness, Cloudy Outdoor

Left — iOS Camera, Right — Lightsynth, Original Photos by Craig Paterson

The core reason of Lightsynth is, through “adaptive multi-zonal exposure metering” technology, helping to get more widely exposure range and your all photos more softly. But lighting situation of above is cloudy. So paradoxically its exposure range and lighting condition is already very soft. Users can be difficult to understand for the advantage of Lightsynth

A Not-So-Good Example 2: Already Good Lighting Condition

Left — iOS Camera, Right — Lightsynth, Original Photos by Chris Messina

Two photos have been taken under already good lighting situation. So the results are almost same! Because Lightsynth is not an app for applying photo effects. It’s an optimizer. Always optimized input will output as same as optimized results.

We are dreaming for finally changing the way to capture the photography from the manual exposure control to autonomous. It will be no easy matter. Even then, would you like to join us while we are walking? We actively want to work with you, Lightsynthers.

Thanks for reading. See with the next post about the whitepaper and background of Lightsynth development.
