RAW Power for iOS Frequently Asked Questions

Do I have to buy the Advanced Adjustment Pack on each iOS Device I own?

No. Once you have purchased it once, you can access the adjustments on any iOS device that has the same App Store account.

To unlock the adjustments, do this:

1) Go into Edit for an image (tap on an image and tap on Edit)
2) Go to the menu in the upper left corner
3) Select Restore Purchases.

Do you support DNG?

Yes. RAW Power supports DNG, including linear DNG files and iPhone RAW files. However, some DNGs from DJI are not supported as is. To check to see if your DNGs will work, open them in Apple’s Preview application for the Mac. If they work in Preview, then RAW Power also supports them. If they are not supported, you can use Adobe’s DNG Converter to batch-convert them to a version of DNG supported by RAW Power. You can download DNG Converter here:

For more information on performing this batch conversion, please contact us on our support page.

How do I get iPhone RAWs into RAW Power?

The built in Camera app does not shoot RAW images, so you will have to use a separate app. Many apps do not save RAWs to the Camera Roll, but a few do. Some examples are Camera+, Halide, and ProCamera.

How do I unlock Curves, White Balance, or Depth Effect?

Those three adjustments are not part of the free download of RAW Power. They are bundled together into a group called the “Advanced Adjustment Pack”. You can unlock all three by purchasing this Pack. To purchase the Pack, tap on the lock icon and follow the steps to purchase the item. Doing so will unlock all three adjustments together.

How do I zoom in and out?

Double-tap to zoom to 100%. Double-tap again to return to zoom-to-fit.
If you pinch to zoom, RAW Power will stop at 100% initially. Pinch again to go past 100%, all the way up to 800%.

I bought the Curves, White Balance, and Depth Effect, but they are locked. Why?

There are two likely possibilities:
1) You deleted the app and re-downloaded it
2) You installed RAW Power on a different device.

To access the adjustments you purchased, please do the following:
1) Make sure you are signed into the App Store using the same account you used to buy the item originally
2) Select an image to Edit (doesn’t matter which one)
3) Tap the menu (upper left corner of the screen) and select Restore Purchases

Is my camera supported by RAW Power?

RAW Power includes support for a very large number of cameras because it uses the RAW engine built into iOS. Apple updates camera support periodically through its software update mechanism. The list of supported cameras (and any limitations) can be found here: https://support.apple.com/en-us/HT207972

Is there a User Manual for RAW Power?

Yes. Click here to download the manual (PDF)

What are the circles next to the histogram?

Those circles light up whenever there is pixel data being clipped in that channel (brighter than can be displayed). There are indicators for red, green, and blue. If you click on any of the red, green, and blue circles, it engages the “hot pixels” feature for that channel only. Clicking on the gray circle shows hot and cold pixels, where red means a pixel is clipped in red, green, or blue, and where blue means a pixel is black (0.0 in all three channels).

Where does RAW Power store its edits?

RAW Power is a fully non-destructive editor and stores its adjustment information in the iOS Photo library. The adjustment information is a small amount of data that includes “instructions” for applying the adjustments — the original image is never modified. If you use iCloud Photo Library, that adjustment information gets synced to iCloud and sent to all your other devices using that iCloud Photo Library.

Why don’t I see the Depth Effect for my Portrait iPhone images?

The Depth Effect is only available for images shot on iOS 11. Previous versions of iOS do not store depth information with the image. If you believe the image was show on iOS 11, but you still don’t see the depth effect, it is possible that the depth information was stripped out of the file. This can happen when emailing or sharing images.

Why don’t I see the People, Places, or Recently Deleted Albums in RAW Power?

Unfortunately, those albums are maintained by the built-in Photos app and are not accessible to other apps.

Why don’t I see a RAW Processing adjustment for my image?

RAW Processing only appears for RAW images — not for JPEGs, PNGs or other image formats.

It is also possible your original RAW was adjusted in another app (Photos on either iOS or macOS, iPhoto, Aperture or perhaps another iOS app). That is because, when you adjust an image on iOS and save it back to the system photo library, the editing app provides iOS with a full-size JPEG (the original RAW is then “hidden” from view). By doing this, other apps can use the adjusted image without knowing how it was made. To get back to the RAW, use Photos to revert the image (by going into Edit in Photos and tapping Revert).

Does RAW Power support lens correction?

Yes. Apple’s RAW Engine automatically corrects distortion and shading for cameras with fixed lenses (e.g., Sony RX100, Leica Q, etc.). It also corrects many images that have lens profile information stored in the RAW files (e.g, Fuji X-T20). It does not, however, have a general purpose lens correction feature.

When should I use Boost?

There are two reasons to use Boost. The first reason is to get the best results for over-exposed images. For those images, decrease the value of Boost to 0.5 or less before using other sliders like Exposure or Recovery. This will allow you to minimize the amount of Exposure or Recovery you need to apply, keeping the image bright. The second reason to use Boost is to get a flatter-looking (more “raw”) image before adding adjustments like Saturation.

What does Recovery do?

Recovery works like “selective exposure.” It affects the brightest areas but without touching the shadows or midtones.

What is the best way to use the White Balance Sampler?

It’s best to identify a reasonably-sized area in your image that should be a neutral gray. Don’t pick a bright white area.

What is the difference between RAW Sharpen and the Sharpen adjustment?

RAW Sharpen (found in the RAW Fine Tuning adjustment) is a subtle sharpener that works as part of the RAW decoding itself. The Sharpen adjustment is a luminance-oriented sharpener that runs after decoding, but still operates on the linear data found in RAW files.

What do the Linear / Gamma and Luminance / Equal RGB controls in Curves do?

The label of the buttons indicates the current state of the control, so if you see “Linear”, then Curves is operating in a Linear mode, but if you see Gamma, then Curves is processing in a gamma-corrected mode. This is also true for the Luminance / Equal RGB button.


RAW Power works with floating point, linear pixel data. If you choose Linear for Curves, then Curves will manipulate the linear pixel data as is. If you choose Gamma, then Curves will gamma-correct the pixels, apply the curve, and then undo the gamma-correction (so the pixel data is converted back into linear values).


Equal RGB means that the Combined curve will apply changes to the Red, Green, and Blue components of each pixel equally. This will affect any tint the image has. However, if you choose Luminance, then the Combined curve will modify the luminance value of each pixel, and will not affect the tint.

Are there any tutorial videos for RAW Power?

Yes. There are tutorials on YouTube at https://www.youtube.com/channel/UC7l78rOzFxaHG-e5AT-MGWQ
