Samsung introduced its Expert Raw app successful beta astatine the extremity of 2021; currently, it is lone disposable for the S21 Ultra. The app allows you to power manual vulnerability settings for each 4 of the rear cameras, which is nice, but the much absorbing happening it allows you to bash is sprout multi-frame RAW files. Here’s what you request to cognize astir Expert RAW – what it is, wherefore it’s useful, and however to usage it.
What is multi-frame RAW?
The abbreviated reply is that it’s RAW but better. In general, RAW shooting saves much information than a JPEG representation file, which is simply a immense payment if you similar to fine-tune things similar achromatic equilibrium and vulnerability photograph editing software. JPEGs are smaller and much easy shareable, but those kinds of settings are “baked in” to prevention space, and they’re overmuch little flexible for post-processing. Plenty of smartphones connection a accepted RAW shooting mode – but with a large disadvantage to shooting a modular JPEG image.
When you instrumentality a photograph successful your phone’s autochthonal camera app, the resulting JPEG (or HEIC) record often includes information from aggregate frames that were captured precise rapidly erstwhile you pressed the shutter button. This allows the telephone to make a azygous representation record with wider dynamic range, making a backlit taxable brighter without adding a full batch of disfigured noise, for example.
Traditional RAW mode connected a smartphone (or immoderate camera) captures a azygous framework that’s much flexible for editing than a emblematic JPEG but loses retired connected the computational benefits that travel with the multi-frame processing you’d get with the JPEG. This makes shooting RAW connected a smartphone benignant of pointless, to enactment it bluntly. Smartphones person precise tiny sensors and lenses comparative to accepted cameras, and they usage these computational tricks to seizure much representation information and compensate for that size disadvantage. As a result, it’s usually amended to conscionable fto your telephone bash its happening and instrumentality a JPEG.
Multi-frame RAW, which respective telephone manufacturers (including Apple) person introduced, makes RAW overmuch much useful, particularly erstwhile you’re taking a photograph with your phone. You get the champion of some worlds: information from aggregate frames recorded into a azygous file, positive plentifulness of flexibility for editing.

The resulting files are large – astir 30MB to 40MB each successful my testing. There’s a high-efficiency RAW enactment you tin toggle connected if you pat the settings icon connected the shooting screen, but it lone saved maine a mates of MBs per image.

In immoderate case, you tin pat the stock icon erstwhile reviewing your representation to instrumentality your photograph into a escaped app similar Snapseed oregon prevention it to unreality retention to edit connected a desktop.
With your representation successful the editing bundle of your choice, you’ll bask much state to propulsion shadows oregon propulsion backmost highlights than with a modular RAW file.
