An app developer has taken the technology that smartphone cameras use to massively improve their photos and applied it to DSLR and mirrorless cameras.
Martin Marek tells SonyAlpha Rumors that he created the free, open-source Burst Photo app to bring the computational photography technology found in smartphone cameras to professional cameras.
“In other words, it is now possible to get relatively usable images at ISO 204,800,” explains Marek.
The app is free and open-source. It is completely free and open-source. I have no financial gain from it. I simply want to help photography enthusiasts enjoy a bit of computational photography on their main camera.”
Smartphone cameras vastly improve the photos taken on their inferior sensors by “stacking” images. The shutter button on a smartphone camera looks only one shot, but in fact many images are taken that are then used to improve the image. This is how Burst Photo works, but instead, users drop RAW files into the app.
By stacking multiple images you can reduce random noise, which results in cleaner output images. This can reveal detail that is not visible in any of the individual images,” says Marek.
The technology not only reduces noise but also enhances color. Marek says that the magentas and greens that are often found in high-ISO images are mitigated.
The app relies on aligning a burst of images. The website guide says that photographers should “try to capture at least five to 10 sharp images without significant movement between them.”
Currently, DNG is the only image format supported by Burst Photo. Some users may have to use the Adobe DNG converter or Adobe Lightroom to convert their files into DNG.
Professional Cameras Strike Back
As smartphones continue to make massive huge inroads in the camera industry, with some bigwigs predicting that handheld devices will soon surpass DSLRs in quality, this could be an early step in fighting fire with fire.
Photo stacking, similar to smartphone computational photography, is commonly used by astrophotographers such as Andrew McCarthy. This process allows for more data, which results in clearer and better final images.
Smartphone manufacturers have long realized the potential of the technology to make huge leaps toward professional quality, it makes sense for mirrorless and DSLR shooters to start taking advantage too.
Burst Photo is available to download in the App Store.
