The Exhaustive iPhone Photography FAQ.

This content originally appeared in my book The Crap-Free Guide to iPhone Photography. It’s now so big, I’ve moved it here to make it easier to update and to keep the book crap-free, as promised.


Should I shoot in High Efficiency or Most Compatible format?

HEIF (High Efficiency Image File) format will likely be the future of photography, with nicer, faster-rendering images than JPEG (Most Compatible) and files half the size. iOS will automatically convert HEIF images to JPEG files for export when appropriate, so there’s really no downside to shooting in HEIF. To switch HEIF on or off, from the Home screen:

  • Tap Settings.
  • Scroll to Camera and tap.
  • Tap Formats.
  • Choose High Efficiency (HEIF) or Most Compatible (JPG).

Should I shoot RAW with my iPhone?

No. Wear clothes. Oh wait…you were asking about the format.

Third party apps like Halide, Manual RAW Camera, MuseCam and Pro Camera by Moment can shoot and edit images in Adobe’s raw DNG format, but the built-in Camera app can’t (except for on iPhone 12 Pro models, see below). The advantage of a RAW file is that you use the original sensor data and have 100% control when editing the final image. On the other hand, 99% of that work is done for you when you shoot a JPG or HEIF image with the Camera app. It’s up to you if that 1% is worth the work. It’s more practical to shoot HEIF or JPG as your go-to and only use RAW for images that really matter or are shot in challenging light. In these instances, you can take advantage of the benefits of editing from the RAW data. But note that RAW files must be edited manually in order to take advantage of that extra 1% since they may not look great as shot.

Should I shoot Apple’s ProRAW format?

ProRAW is the latest version of the DNG format that Apple helped develop with Adobe. It’s only available as of this writing for the iPhone 12 Pro models. You can edit a ProRAW file in any software that edits DNG, but few are optimized to take full advantage of the format. A ProRAW file is just a DNG v1.6 file, which added data maps from Apple’s computational photography normally applied to finalizing the JPEGs and HEIFs. Apple is the first to take advantage of these, so you can shoot ProRAW with the Camera app and edit ProRAW with the Photos app. You’ll find more on ProRAW here, including current photo apps optimized to shoot and edit with it.

Are my photos anonymous?

Geotagging your images allows you to easily find them by location where they were shot in the Photos app’s Places album. But this information may be passed on with the image when you upload files to the net or share them. (Not a good idea when shooting photos of things of value in your house.) Photos sent by email or iMessage will include geotags. The most popular social media apps like Facebook, Instagram, Twitter and Reddit safely strip out geotags. But photosharing sites typically leave them in. Your two options for privacy are to turn geotagging off when you shoot or use an app to remove the geotag when exporting. To stop geotagging your images. From your Home screen:

  • Tap Settings.
  • Tap Privacy.
  • Tap Location Services.
  • Scroll to Camera and tap.
  • Choose Never.

To remove a geotag from an image try Metapho or the NoGPS Photo Extension.

How should I clean my iPhone camera lens?

Just wipe it with a clean microfiber cloth intended for eyeglasses. Don’t use glass, eyeglass or screen cleaning solutions on your lens. These can damage the coatings and fog the lens.

Can I turn Live Photo off?

Live Photo is on (yellow) by default for iPhone 6s or newer. If you want it to stay off, from your Home screen:

  • Tap Settings.
  • Scroll to Camera and tap.
  • Tap Preserve Settings.
  • Turn Live Photo on. (Not a typo.)

Will gear like tripods and lens attachments improve my images?

Your iPhone cameras and computational processing leave little need fort these. But if you plan on shooting a lot of night images, a tripod can be really useful. Also, if shooting closeups, a macro lens attachment comes in really handy. But just the phone in your pocket will give you great images without having to carry around any extras. But, if you must, here’s an article on the best iPhone photo gear.

How do I shoot a great selfie?

Times times as many people have died taking selfies than from shark attacks (true). I wouldn’t encourage you to swim in shark-infested waters, so I won’t encourage you to take a selfie.


What does the Brilliance slider in the Photos app do?

It’s somewhat of an all-in-one light editing tool, sensibly combining adjustments for contrast, brightness, shadows and highlights in one slider. If the magic wand slider isn’t doing it for you, the Brilliance slider is a good next step for improving images.

Can I copy a photo?

Easily. With the photo open in the Photos app: Share (up arrow) > Choose Duplicate.

What’s Markup?

Markup lets you annotate your photos in the Camera app and the Photos app. With the photo open:

  • Tap Edit.
  • Tap More (circle with three dots icon).
  • Choose Markup.

You can write on the image and add text boxes, shapes, arrows and magnifying glasses. But no mustaches, thank gawd.

How do Photo Extensions work?

Photo Extensions allow you to call up editing apps and utilities from within the Photos app. There are appless extensions, as well as extensions built into editing apps (like LUCiD and TouchRetouch.) To enable an extension:

  • Open a photo and tap Edit.

  • Choose More (circle with three dots icon).

  • Scroll icons left and tap More again.

  • Switch on any available apps you want.

  • Tap Done. 
 To use the extension:

  • Open a photo and tap Edit.

  • Tap More (circle with three dots icon).

  • Choose the extension’s app icon.

  • When through editing, tap Done.

How do I add a caption to a photo?

This feature was added in iOS 14.

  • Open the photo in the Photos app.
  • Swipe up.
  • Tap Add a Caption and type your text.
  • Tap Done.

Currently there’s no way to caption multiple photos. The best option is to copy and paste.


Can I sell my iPhone photos through microstock photo sites?

Yes. But our multi-year study here are Crap-Free Labs (sad to say) shows across the stock industry, the supply of images and eager photographers is exceedingly high and growing. As a result, demand and prices are exceedingly low and falling. Many one-time sales of images get you less than a dollar and many services require you to rack up $50 in sales before you get paid. That means you have to be incredibly active and successful or you’ll never see a penny. Our assessment: the work involved with uploading, tagging and filling out the virtual paperwork involved doesn’t pay minimum wage.

If that doesn’t discourage you…In our study, the best microstock site currently is Twenty20. They have a nice app, pay all you’re owed monthly, have their own encouraging social community and are geared toward making you a better photographer.

You’ll often see pros watermark their photos with ©, the year and their name. Technically every photo you take is copyright the moment you take it, you’re just notifying everyone with the mark. Officially filing your copyright with the US Copyright Office is helpful in a court case. Even if you don’t file, adding a copyright watermark with an app like Impression or Photo Extension Watermark might minimize theft of your photos when they’re posted in public—if you’re that concerned about it. You can officially file for copyright on a collection of images that were all shot in the same year for $35.
