Capture Option for Low Light Conditions - take multiple photos and stack out the noise

At the moment, low light conditions pose a bit of a problem for the cameras and can result in very grainy/poor quality images in the models.

In order to improve the images it is possible to take multiple photos of the same "spot" and then combine those photos later during processing.

This technique is commonly known as "stacking" which is basically improving the signal to noise ratio.

Here's an article that helps describe this technique:

That said, it would be nice to be able to have a 2nd Capture Button in the Capture App that would allow you to take a slower than normal capture (slower because it will be taking more photos) in order to capture areas with low light levels.

Please like if you agree! :-)

  • @ssquires32 I shot a museum with black walls and ceiling - and a few very harsh flood lights. Lots of chroma noise. Great idea!!

  • Totally agree and very much like the idea. This stacking technique is what's already done to remove flicker patterns with LED and some fluorescent lights, so it can certainly be done for noise reduction too. You're right, it would take a bit longer to capture, so having a checkbox or toggle for "night mode" would be ideal.

    Thanks for the suggestion. I'd love to see this one move forward.

  • Doesn't the HDR camera already stack (or more accurately, bracket) the photographs to account for differing light conditions? If so, would this just be an adjustment of the lower limit of the stacking?

  • Stacking is very similar to producing an HDR image. Instead of using multiple images at different exposures, with stacking the images used would all have the same exposure. The software then looks for differences in the image noise pattern in order to reduce it in the final image.

  • Thanks Amir - can you pull some strings to get it on the developer's to do list? :-)
