iOS 11 quietly introduced a camera level that helps you take pictures that don’t suffer from skewed sides. Read on to learn how you enable and use this subtle feature.

Thank you very much, Josh, for this quick but nevertheless quite useful tip! Now I finally know what those mysterious crosshairs are for…

Best regards, Rainer

Josh – This is more useful than you realize! I agree that not many people do product shots but A LOT of people take photos of checks to deposit remotely!


(BillD) #4

Yes, and Halide does both skew and level with haptic feedback for both. It would be such a great thing if Apple let people switch default camera apps.


(Josh Centers) #5

Does that work in banking apps? Hmm, that’s the only way I deposit checks. I’ll have to look into that…


(David Price) #6

My bad. I forgot that banking apps have their own camera. I wonder if the API is there for the banking apps to utilize it?

If you use notes to scan documents, it will deskew papers pretty much automatically, even if you aren’t precise. It makes scanning multiple pages very fast.

Sorry, Josh, I haven’t got the cross-hairs, even though I’m running 11.3. I guess it’s because my iPhone is the 7. Perhaps it’s a new feature with the 8.

That’s odd — once the grid is turned on, the camera level feature works fine on Tonya’s iPhone 6s.


(Josh Centers) #10

Are you pointing the camera up or down? They won’t appear otherwise.


(Brian Caswell) #11

Ah, I missed that critical point! I was interpreting “level” in a different sense. No problem now!


(Seth Anderson) #12

Yes, I had the same “reading comprehension” issue - I was pointing my iPhone straight ahead (towards a wall) instead of towards my desk. ¯_(ツ)_/¯


(Adam Engst) #13

I’ve edited the article to be more clear. Now it says that the camera level “appears only if you’re pointing the camera straight down toward the floor or straight up toward the sky.”


(Joan Miller) #14

Thanks! I’m always off-kilter when I photograph a check for bank deposit – this will help immensely!

How could I NOT have known about this. Can’t count the times I would have used leveling but must be hundreds of times documenting Linda’s art projects. Thanks for sharing. Why hasn’t Apple created a tip for this? or did they?

This leveling device would have been truly useful to many more people if it functioned when the mobile device is held vertically. Then it would trully fulfill its universal need when photographing objects, people, landscapes, urbanscapes, etc. These are the subject matter of most photographs. Artworks hang on the wall, not the floor or the ceiling. Distortions of the vertical plane are just as unwelcome as those in the horizontal!


(Alan Forkosh) #17

The problem in that it fixes in the horizontal plane is distortion of the image by not holding the camera parallel to the surface; that is what the level indicator solves. Most people are pretty good at aligning the camera in the vertical plane. The problem is that they don’t level the edge; so the picture is skewed but not distorted. Theoretically, you can line up the grid line with an edge to prevent that, but the grid lines often are nowhere near an edge. However, the skew can be fixed in editing via the rotate and crop function.


(Seth Anderson) #18

that’s what I use the grid for. My DSLR (and many other kinds of cameras) also has a grid overlaid onto the scene, but there too, the photographer has to manually line up the subject with the grid.

Works find on my iPhone 5s.

I wish I had known about this way earlier, it would have saved me a lot of effort. I have spent many hours taking photos of standard letter size pages. I usually take the pics in Camera.app but process them in Scanbot, which does a great job automatically cropping to the page when you have a nice straight scan.

Previously I jury-rigged a copy stand from my old Beseler 45MCRX enlarger and set a board at the film plane as a little platform to set my iPhone or iPad on and keep the camera locked and level. I use the electric motor to run the platform’s height up and down for big or small document scans.

To lock down the level, I used the Compass.app’s level (Hey Siri open compass -> swipe left) and set my iPhone to level and checked the target surface was level. That’s better for mass capture. I sometimes copy whole books or stacks of paperwork, I can shuffle hundreds of pages per hour under the copy camera.

It’s a little more effort to get centered and leveled with this camera gadget, but for a quick copy shot it works great. I started using my new iPad Pro 12.9 to take copy shots since the camera is better and it has optical stabilization.

BTW I might turn my old Beseler back into a photo enlarger. I understand there’s a new Beseler M refurbish kit and apparently there is a retro revival demand for gigantic 4x5 film enlargers and other vintage darkroom equipment from 50 years ago.
