Hands On With PiRAWnha, a RAW Photo Editor for iPad
Posted in: apps, ipad, photography, Software and Operating Systems, Today's ChiliPiRAWnha is a RAW photo developer app for the iPad and, while it gets the job done, its a little rough (raw?) around the edges.
The app scans your photo albums for RAW images and presents them as thumbnails. Tap one and you are dropped into some simple editing controls, above which sits your unprocessed RAW image. From here you can tweak exposure, saturation, white balance, and contrast, along with several other basic adjustments. You can also add noise reduction and sharpening, and a histogram is displayed at all times to help out.
So how does it do? Not so well. First, the RAW rendering – which converts the soup of data in a RAW file into a viewable picture – is rather poor. An indoor shot, taken at a ISO 1600, shows a lot more noise than it does on either my Mac or in-camera (using the camera’s self-generated JPEG preview). It also has a lot of red speckles sprinkled over the picture. These spots disappear when you export the processed photo to a JPEG, though.
The app is also very slow. This is thanks to the iPad itself, which has barely enough RAM to do something as hard as RAW image processing. In fact, I got a low-memory warning with every button press when I first launched PiRAWnha. You’ll need to restart before you use it.
And you might want to make some coffee, too. Each edit causes the image to re-render, and it’s slow. A button push can cause a wait of around ten seconds, making editing painful.
PiRAWnha claims to be the first RAW editor for the iPad, but there are plenty of other non-RAW editors which do the job better. The only reason to edit RAW photos on the iPad is to email them, or to make a quick slideshow before you get back to your proper computer. Given that every photo-editing app will handle the JPEGs that come tucked inside your RAW images, and handle them better and faster, there seems little point in PiRAWnha.
As a proof-of-concept I like it, but as a day-to-day app I don’t. Add to this the interface design – you can only edit in portrait mode, for example, and if you tilt it into landscape orientation when viewing thumbnails, they don’t reflow to fill the screen – and you have something that is fun, but not yet fully baked. $10.
