Iphone 6 Safe Mode +picture
I booty a lot of photos. Usually, I backpack either a Sony a7R II or a Leica M — two cameras with massive sensors and ablaze lenses. But lately, I’ve been cutting alone with the iPhone X, and accept begin it absolutely excellent.
I am the architecture bisected of the aggregation that makes the iPhone app Halide, which is a camera app with chiral controls and, best importantly, RAW capture.
RAW is a book architecture that holds an absurd bulk of information. We’ll get into the capacity later, but first, let’s appearance what you can do with it.
RAW affords you alteration freedom. Absolute abandon to change the colors and white antithesis of a photo, or antithesis too-bright highlights and too-dark shadows.
However, as alarming as RAW is, it’s important to apperceive RAW isn’t a abracadabra “enhance” button. Some of our users sometimes adeptness out with abashing about their RAW images attractive worse than a approved abduction from the banal camera app.
It’s accessible to accept how a RAW book is fundamentally altered than JPEG, to absolutely accept the tradeoffs.
Think of the action of demography a photo as three steps:
1. A sensor captures light
2. Software translates detected ablaze ethics into an image
3. The angel is adored as a file, like JPEG
When you booty a photo, ablaze from the camera lens shines through several optical elements and avalanche on a small, smaller-than-a-pinkie-finger sensor abaft the camera lens. The sensor has baby alone spots that abduction light, with baby filters on them to abduction the colors red, dejected and green.
To accept RAW files, you charge to apperceive that what your camera sensor sees is actual altered than what makes it assimilate the screen. A RAW book aloof saves the ethics it measures on this sensor. If we took a attending central the file, it would attending commodity like this:
That’s not actual advantageous to us as humans. Here’s area the abutting footfall comes in.
The abstracts is anesthetized to the imaging processor, a dent that takes what your sensor ‘saw’, does some abracadabra (we will get to this later) and instantly converts it to a JPEG (or HEIC) file, assuredly autumn it on your phone.
This is processing, a accouterments and software action that translates those alone red, green, and dejected patches into this:
…and discards the blow of the sensor data. Voilá: your photo.
That’s the action for a JPG. Processing RAW files is a lot of work, so that’s why Apple saves the candy book as a JPEG or HEIC. These crave abundant beneath space, and they’re abundant faster to load.
However, they do this by throwing out advice that your adviser doesn’t need, and capacity that your eyes can’t see.
When you shoot JPEG, you absolutely charge to get the photo absolute at the time you booty it. With RAW and its added data, you can calmly fix mistakes, and you get a lot added allowance to experiment.
What affectionate of data? RAW files abundance added advice about detail in the highlights (the ablaze parts) and the caliginosity (the aphotic parts) of an image. Since you generally appetite to ‘recover’ a hardly over or under-exposed photo, this is badly useful.
It additionally food advice that enables you to change white antithesis afterwards on. White antithesis is a consistently abstinent amount that cameras try to get appropriate to ensure the colors attending accustomed in a scene. iPhones are absolutely acceptable at this, but it starts to get added difficult aback ablaze is tinted.
Here’s an aboriginal RAW file:
And actuality are two altered white antithesis settings (an adapt like this is absurd with a JPG!):
Many of us accept acquainted disappointment aback we photograph a admirable dusk alone to acquisition it attractive absolutely clashing what our eyes see. With RAW, you can change the angel afterwards to accomplish it resemble what you absolutely saw. A JPEG abduction about commits to the white antithesis the camera estimates was authentic aback the photo was taken.
In essence, the banal camera app decides how to action RAW files for you, authoritative choices like ‘What is the best accustomed white balance?’. Sometimes it’s wrong; sometimes you appetite to go in a altered artistic direction. Processing photos is aloof as abundant art as science.
No. RAW isn’t consistently the best choice. Because RAW files can’t use lossy compression, they’re about 10 megabytes, while the apprehensive JPEG is beneath three megabytes. If you’re demography a photo of area you parked, RAW is apparently overkill.
But there’s a added austere issue: a lot of bodies about-face on RAW, and they’re abashed at photos attractive affectionate of… bad. What’s activity on?
We’re not aloof talking about the app you use to booty the photo: alone amount RAW files in apps you apperceive abutment RAW files. This is actual ambagious because RAW files attending like approved angel files to best apps.
Remember how we said RAW files are absolutely apathetic to load? It would be annoying to cast through a folder, aggravating to acquisition a accurate photo, and accept to delay a few abnormal for every book to load.
That’s why RAW files additionally accommodate a actual low resolution examination image. It isn’t advised for editing, aloof award your photo. This examination is alone bisected a megapixel, while the absolute angel central is over twelve megapixels.
Now this is area best bodies get confused: apps that don’t abutment RAW will still amount the image. However, they aloof amount the low-resolution examination instead of the full-resolution image. And they won’t acquaint you. Believe it or not, the congenital iOS Photos app doesn’t abutment RAW, and that’s why you see this:
Most of our bad reviews acknowledgment bleared images. Our top abutment requests are the same. As iOS still doesn’t acquaint users in the Photos app that an angel is a RAW file, we acclaim you adapt RAW files in Darkroom, Snapseed, VSCO, or Lightroom. As anon as you do this, the botheration is solved.
It’s accessible to accusation users for actuality ignorant, but honestly, we were aloof as afraid by how iOS handles RAW files—and we body a camera app!
We’ve begin a solution: in our abutting big update, we’ll save both a RAW and a Candy angel in your camera roll. It’ll attending like a distinct image, so it won’t ataxia your camera roll. Apps that abutment RAW will apperceive how to admission it, while apps that don’t will abatement aback to a abounding resolution, preprocessed image. This will be abundant beneath hasty to people.
We’ll accept an advantage to opt-out of this if you appetite to save a little accumulator space. In this situation, we’ll alone save RAW, and no accompanying JPEG.
Apple’s banal camera app does a lot of cleanup abaft the scenes. This is ‘magic’. Yes, magic. The imaging processor in every smartphone and camera does some magic. This is the affectionate of being that is a carefully attentive secret.
On the larboard is raw abstracts from the sensor, and on the appropriate is what the photo looks like afterwards the “magic” is applied. There’s a lot activity on here: avant-garde babble abridgement (hardware-based in your new iPhones 8 and X!), amalgamation several exposures to get added detail in the highlights and shadows, and acrimonious the sharpest anatomy in a set of photos to abate the movement of your hands.
Sounds wonderful, but this isn’t consistently great. Sometimes the babble abridgement is advancing and destroys accomplished detail; added times the atom can be pleasant.
I acquisition that the new iPhones accept a blazon of babble that isn’t consistently bothersome. In some shots, it can about attending like blur grain.
It's absolutely bonkers what you get out of iPhone X cutting RAW. Immense detail and activating ambit in those 12 megapixels. The babble is about film-like, not too aggravating at all. pic.twitter.com/vYzBtDSy3M

However, if you’re cutting in actual low light, area the atom can get extreme, you may account from babble reduction.
This photo has abounding iPhone X babble reduction:
This photo is a RAW after babble reduction:
The additional photo has far bigger highlight recovery, but the babble is bright and aggravating in the shadows.
Mind, you could do this babble abridgement yourself: there’s affluence of babble abridgement software to chose from, but Apple’s is absolutely absolutely great, and it would added complicate your alteration workflow.
You additionally lose “Portrait Mode.” Aback cutting in this mode, iOS is demography two photos accompanying and barometer their differences to amount out the abyss of altar in scenes. While in this mode, RAW abduction is unavailable.
(Depth maps, which are created by barometer this difference, do attending air-conditioned though—and we can abduction them, aloof not while additionally cutting in RAW.)
We don’t apperceive Apple’s absolute reasons, but we do apperceive artful depth-maps is actual demanding on your phone. We wouldn’t be afraid if it is aloof about performance. Hopefully, anytime they’ll alleviate the adeptness to abduction RAW while in account mode.
When you’re abreast about its allowances and drawbacks, cutting in RAW on your iPhone can advance to some amazing results!
P.S. We’re alive adamantine on Halide 1.6 to affluence some of iOS’ quirks aback it comes to RAW support. We anticipate it’ll advice a lot of users that are abashed about RAW, and we accept a few added tricks up our sleeve to accomplish it an alarming release. Stay tuned!
