General
Is it a new raw file format? No!
Dotphoton Raw is not another proprietary raw format. Compressed images are converted into DNG, the format trusted by Leica, Sony, Apple, Pentax, Ricoh and other leading brands.
Can I use compressed images in Lr, C1, etc? Sure!
Dotphoton-compressed images don't require decompression and are compatible with main photo editing software, i.e. Adobe Lightroom, Adobe Photoshop, Capture One, DxO Mark, Photo Mechanic etc.
Just compress images in Dotphoton Raw and import them into your software.
Will my image resolution get decreased? No!
We don't downgrade your image resolution and bit count. We care for quality, that's the reason why we've launched this product.
Will my images stay mine? 100%
Dotphoton doesn't upload images anywhere online and doesn't have access to your information apart from camera model, which allows us to effectively control compression quality. The app works offline. Compressed images are exported into the folders where you want to have them on your desktop, disks, clouds and even if you'd stop using Dotphoton Raw they will be there and be yours forever.
Will I be able to print compressed images? Of course!
Just as your usual raws, you can convert Dotphoton-compressed images into any print format. Image resolution after compression stays exactly the same as in your original file.
Windows edition? Soon
We are already working on it. If you'd love to be notified, please shoot us a note at raw@dotphoton.com

Why some files get copied: camera support limitations
Dotphoton Raw features a number of technological limitations. After compression, a file subject to such a limitation will get copied to the export folder completely intact, so you couldn't accidentally delete them along with the source folder.

General limitations
  • Not compressing files, already compressed in Dotphoton Raw
  • Not supporting ISO bigger than 65000
  • Not supporting DNG with lossy compression applied before, for example if "Use lossy compression" setting in Adobe DNG Converter was switched on (Linear Raw)
Brand-specific limitations
  • Fuji. Not supporting files with "Dynamic Range" setting switched to other than 100%
  • Canon. Not supporting files with sRAW / MRAW setting switched on (lossy compression).
  • Nikon. Not supporting lossy-compressed settings, i.e."Lossy Compression", "Small" RAW size
ISO limitations
Not supporting files with ISO higher or equal to these values:
  • Canon EOS 5D Mark III. <25600
  • Canon EOS 5D Mark IV. <32000
  • Canon EOS 5DS. <6400
  • Canon EOS 5DS R. <6400
  • Fuji GFX 50R. <12800
  • Fuji GFX 50S. <12800
  • Leica M10. <6400
  • Nikon D700. <6400
  • Nikon Z7. <51200
Will there be more cameras supported?
Sure! You will learn about new cameras next time your copy of Dotphoton Raw will be automatically updated. To get the latest news, please follow us on instagram.com/dotphoton and twitter.com/dotphoton. You can also subscribe to our newsletter at Raw.dotphoton.com
Do I have any impact on when my camera will be supported?
We are super open for your feedback. Please help us make Dotphoton Raw available for your camera ASAP by upvoting it on the list here.
Will Dotphoton Raw compress my DNGs?
Yep, if lossy compression wasn't applied to them in-camera or after compression in some different software.
Installation, updates
Is there a Windows edition?
Not yet, but we are aiming for it. We are in no way interested in discriminating artists by their machines and we'll roll out the Windows edition as soon as we get ourselves on a more solid ground with the product we have now.
Why do I need to install Adobe DNG Converter?
In order to provide the best possible compression some of the files will require a free copy of Adobe DNG Converter on your system. If you uninstall Adobe DNG Converter, Dotphoton Raw will not work until you install it back.


How do I uninstall Dotphoton Raw?
Simply delete Dotphoton Raw.app file on your system. If you don't remember where it is you can ppen Spotlight and enter Dotphoton Raw.app in the search field to locate and delete the file. If you would also like to uninstall Adobe DNG Converter which goes with Dotphoton Raw, you can also delete it from Applications folder.
How do I update my copy of Dotphoton Raw?
Updates come automatically, so there's no need to manually update your Dotphoton Raw. You will see an update notification as soon as it will get updated. Alternatively, select Dotphoton Raw from the macOS top navigation bar and click Check for Updates
Is there a trial version of Dotphoton Raw?
Sure, it will allow you optimize 100 images to give it a try. Please follow this link
Compression
What will happen to my source files after compression?
Dotphoton Raw will not overwrite your source files, they will remain intact. After compression a new copy of each file is created which will be up to 7 times lighter preserving full quality.
Where will my compressed images be stored?
It's for you to decide: choose or create a folder from 'Save to' bottom menu or chose one of the previously used folders by clicking 'More'.
What's your compression ratio?
1:3–1:8 depending on the information stored in your image.
Why DPR says that some images imported are not supported?
There are basically two options:
1. You are trying to compress images that can't be compressed due to our limitations or from an unsupported cameras (see website for full list).
2. If the number of imported images and compressed images are the same, but DPR still says some of them were not supported, there might have been a hidden macOS system file among the files you've imported that we can't define since they are protected by your system.
Why does Dotphoton Raw add .p extension to my photos?
This is so you wouldn't forget that those images are already compressed by Dotphoton Raw. The additional .p extension will go away in the upcoming update, though. Meanwhile, here's a quick fix to rename the files: http://osxdaily.com/2015/05/28/batch-rename-files-mac-os-x-finder/ and also a number of alternatives here https://alternativeto.net/software/namechanger/
Does DPR retain the metadata of the original file? (Thank you, Richard!)
The only metadata tag that we've found not getting transferred to the output files so far is the Noise Profile.
Subscription, license
What is my license number?
It's a number you use to activate your copy of Dotphoton Raw. You can find it in the e-mail that we've sent you when you purchased the license, upon logging in to my.dotphotonraw.com or in the app's Check license window.
How can I renew my subscription?
Subscription will renew automatically. If it didn't happen, open Check license window and click Renew now.
Can I cancel my subscription?
Unfortunately, you can't.
What will happen to my images if I don't renew my license?
Absolutely nothing will happen. Your images will be stored wherever you store them and they will be editable at any time as DNG is an open raw format. The only change for you would be that you will not be able to compress more images with Dotphoton Raw.
Can I install Dotphoton Raw on multiple computers?
Yes, your license key will work on two Macs. Any additional computers will require purchasing another license.
Why my license is deactivated and what can I do about it?
Basically there are three options.
  • Your order was canceled or refunded, which rendered the activation code invalid.
  • We've noticed some potential fraud activity connected to your license and blocked it.
  • You've used your license key on more than two Macs, so one of the first two got automatically deactivated.
How can I move my license to another computer?
As for now we can only do it manually for you by switching off one of your already used licenses. Please contact us at raw@dotphoton.com
How can I get my money back?
Please mail us at raw@dotphoton.com so we could help you.


Why subscription?
Exactly like many photographers out there, we've also been somewhat frustrated by some of the subscription policies of the big software companies. But unfortunately, subscription model is the only viable way for indie developers to keep making our products better for our customers every day and not just sell out new versions once in a couple of years.
Promocodes, gifts
How can I redeem my promocode?
Easy, peasy, lemon squeezy. Go to Check license window, click redeem and enter your promocode. You will see an alert in case of success or a error.
Where can I get promocodes?
Follow us on instagram.com/dotphoton and twitter.com/dotphoto to participate in our promos.
