Found iPad app for DNG files

Thought you guys might be interested to know that I found an app called photoraw that works on the iPad . You can load dng files that you have transferred to the iPad using the camera connection kit for viewing and developing and then save as a full size or reduced size jpeg . It's great for editing on the go, I then load the jpeg into the PS express app for further editing.

The app can be set to use virtual memory so it can work on very large raw files.

I've had it for a few days already. Works really well, even though on my iPad 1 it's rather slow.

On a friend's iPad 2 it worked much faster.

So, I wouldn't really recommend it for the iPad 1, but for an iPad 2 it's really good.

Is it possible to tell what DNG's it will read. I have a DMR...

There's a list of supported cameras on their website. In addition, they told me that (at least in my instance) there is unofficial support for further formats built-in, which they do not make public due to performance, reliability, or other issues. I'm trying to make this work with Phase One files, but no success yet. My advice is to try the free Lite version, and maybe you're lucky.

As a matter of curiosity, which Phase back?

 

Sandy

It's the P45+. I've already tried changing the back from IIQ to TIF, but the files are still not being recognized. Others have reported success with this method though (possibly with other P1 backs, I don't know), so it might be some problem on my end. It would be great if that worked, because P1 backs don't know anything about RAW+JPG mode, hence no possibility until now to offload and view files on the iPad.

It could also be related to how you're importing; for import from the Photo Album to work, the iPad has to recognize the file as an image file before it will even show it to PhotoRaw. I'd suggest trying doing a file transfer via iTunes, and see if that works.

 

Alternatively, send me the file via YouSendIt, and I'll see what's up.

For the DMR, here is a quote from their iTunes Store:

 

"for example Nikon NEF files, Canon CR2 files, Leica DNG files, etc -"

 

So in my opinion, it should work with R, M, S2 and X1. I am waiting for my iPad2 (sold my iPad 1 too early...)!

It will work with DMR files. But try the Lite version first....

Hi Sandy

 

Why do you suggest the "lite" version for DMR DNG files? I really need the full version for multi camera support. If it works it will be my ideal scenario and just what I have been waiting for :)

 

A friend of mine with iPad 1 and the full version can't open my DMR DNG's. He is going to try some of his M8's DNG's later tonight.

 

Thanks, Julian

The "Lite" version will allow you try out the software without paying - there isn't any difference in ability to open files between the Lite and full versions.

 

If you ( or your friend) have trouble opening a DMR file, please email me via PhotoRaw's "Contact Us" function (on the help screen). That will send me a log file that will tell me what PhotoRaw is or isn't seeing - most problems like that tend to be related to the iPad's Photo Album only storing a JPEG representation of the file, not the raw raw file itself.

I have one question regarding the app and the iPad. I can import my photographs into the iPad from my D-Lux 5 by using the Camera Connection Kit's SD card reader (the USB reader doesn't work as the photo file can't be found due to Leica's file set up) but what it does is change the meta data in such a way that once imported into Lightroom 3, it shows the photograph as being taken by an iPhone, which clearly isn't the case. Does the PhotoRaw app keep the meta data as a photo from a Leica camera?

PhotoRaw doesn't change any metadata. However, be aware of two things - (a) the D-lux 5 isn't yet officially supported, and (B) you will still have to use the Photo Album app that's built in to the iPad to transfer from the SD card to the iPad. Apple do not allow, as a security measure, any non-Apple app to directly access the card :mad: So whatever the Photo Album import process does now, it will continue to do.

So, apart from what's been said already about Photoraw, what advantage does it have, or give you that the inbuilt app from Apple doesn't do already. I've had no problem opening photographs, or with importing them into the photo app apart from the meta data problem. I've actually emailed Apple about that and hope they will fix it.

Looking forward to your responses as my finger is hovering over the 'buy' bottom for Photoraw.

Oh, give Adobe's Photoshop Express app a go as it works well for quick editing.

Kind regards

 

 

Cheers, Macjim.

The main advantage is that with PhotoRaw you're seeing the image at 1:1 with the same kind of demosaicing that you'd get on a desktop machine - the in-built apps are showing the JPEG thumbnail image, which at lower resolution. Usually very much lower.

 

But I'd suggest you download "PhotoRaw Lite", which is free, and play with that before buying. In terms of viewing images, it can do everything that the full version can.

 

Regards,

 

Sandy

Thanks....

 

Unfortunately, I found it (the lite version) too slow on the original iPad. Oh well. Perhaps the iPad2 would be more effective.

 

Either way, there are far better "image-tank" solutions than the ipad out there.
