PhotoRaw for iOS is a viewer and developer for image files in raw format. Raw file formats from most camera manufacturers are supported, for example Nikon NEF files, Canon CR2 files, Leica DNG files, etc - see the product web site for a full list of supported cameras. PhotoRaw allows you to view these files at full 1:1 pixel resolution, even 100 mega-pixel plus medium format images.

PhotoRaw implements virtual memory. Virtual memory means that if PhotoRaw runs low on physical RAM because of other apps running the background, it can use the device's flash memory to process even the largest images. PhotoRaw has been tested with images of up to 72 MPixels on both iPads and iPhones, even with multiple other apps running the background.

Most images viewers for the iPhone, iPad and iPod Touch are only able to display low resolution thumbnails of raw images, making it difficult to use the iPhone or iPad to evaluate and view raw files in the field. PhotoRaw changes all that. PhotoRaw incorporates a state-of-the-art AHD raw image demosaicing algorithm right into an iOS app. So now you can view every single pixel in a raw file, without needing a desktop machine or laptop.

To ensure that you see your images in a form as close as possible to what you'll see using a full featured desktop raw developer program such as Aperture, PhotoRaw incorporates a full demosaicing engine, as well as basic exposure controls such as exposure, contrast and brightness. You can even control sharpening to make sure that the image looks its best.

You can also export images, or cropped portions of images, from PhotoRaw in JPEG or TIFF format. So you can email a processed, cropped JPEG to clients or friends right from your iPad or iPhone.

Limitations:
·  PhotoRaw supports only raw formats; JPEG, TIFF etc images are not supported
·  Importing large raw files can take up to several minutes, especially if other apps are running in the background

System Requirements: Raw conversion requires very substantial amounts of processing power and memory. We strongly recommend the following minimum system specifications:
·  iOS 8 or later
·  iPad or iPhone 4 or later

## Key features

- View raw image files at 1:1 resolution
- Supports most camera raw formats

### 5/5 — Outstanding customer service

*2019-11-20, version 4.5.1*

I reported a problem via email and they immediately responded. Together we diagnosed the problem and they had a fix in place within 24 hours. Now that’s customer service!

### 5/5 — Best app for opening my big Olympus raw files!

*2017-02-24, version 4.4.6*

Currently, one of my favorite photo apps.
It opens AND saves BIG files. I had to play with the sharpness settings before I got good results. I am using a 3rd Gen. Retina iPad. Yes, it takes awhile...but it opens the 80MP Olympus E-M1 Mark II High Resolution Raw files! Amazing. There are some quirks, but it works.  I also often use PhotoGene, which is a great and more full featured app, but this has its strengths. I sincerely hope it is further developed, and thank you to the creators!

BTW: Study the description and screen shots BEFORE you buy. What you see, is what you get. Check the developer's site, because there's lots of documentation, helpful tips and information there to help you make an informed decision. If you make a mistake, is it right to blame someone else?

### 1/5 — I'd like a refund

*2016-09-12, version 4.3.19*

This app doesn't work, no matter how I import the files, says .nef are not raw

### 1/5 — Worst photo app

*2016-05-30, version 4.3.15*

This is the first app review I have ever written. I recently purchased an iPad Pro and wanted to see how it handled some RAW files. This app claims to process raw files, and at 10$ I assumed it would live up to its claims! It has minimal editing functions, and the major reason to shoot and edit in raw- exposure adjustments are the worst I have EVER SEEN. A single positive or negative shadow/highlight adjustment creates instant posterization destroying the photo instantly. Not sure what the point of this app is or how I go about getting my money back. It is that bad.

### 5/5 — Great Much Needed Update for RAW shooters

*2016-03-19, version 4.3.7*

This app works great on my iPad Pro, and is one of the very few to work directly with RAW files. Simple and easy to use, and the results look professional and beautiful.
I'm using it with Canon RAW files, and files from my fantastic new X-Pro2 from Fujifilm. This is one of the first apps to support the new Fujifilm camera for RAW files that I've found.

Two things I would love to see added: A white-balance touch tool (where you touch a neutral color to white balance the image (maybe the app already has one that I haven't found); the ability to export the original RAW files (I have yet to find an easy way to get RAW files off of my iPad to conserve storage space once I am done with them).

As it is, it is a great a very useful app, so five stars!

### 5/5 — Awesome App

*2016-02-05, version 4.3.6*

This app is very nice. It has a lot of technical ability, extensive raw support. I just wish it could edit exif data.

### 5/5 — excellent processor

*2015-11-12, version 4.3.5*

added select all, which makes batch work really useful. hopefully the highlight/shadow problem is improved, or maybe an export dng option (more universal) so we can use another app to tweak the highlights/shadows?

### 4/5 — Excellent App!! More functions

*2015-09-26, version 4.3.4*

This app is amazing!! Please add more functions!!!

### 4/5 — Works well at low-medium ISOs, but....

*2015-08-12, version 4.3.3*

Really needs a noise reduction feature at high ISOs.  Also, a batch adjustment mode would be nice, where it applies the same adjustment to several RAW files.  In its favor, it seems to be the only app out there that can process the RAW file from a RAW+JPEG pair imported through the camera connection kit.

### 1/5 — Worthless

*2015-05-22, version 4.3.0*

It will not open raw nef files from dropbox.  I dont need it for files from photos.
