Yes, in any photo-editing software supporting DNG, basically most of the professional apps out there.

It 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.

Most of the modern compression algorithms tend to be «visually» lossless — meaning that they are lossy — but the reduction in quality is only noticed on close inspection. However, at Dotphoton we believe this is not enough for professional photographers. Dotphoton algorithms create no artefacts and retain image information, so they are as suitable for post-processing and archival as regular raw files.

Technically, Dotphoton introduces a small scientifically controlled loss of 0.3 bits of information per pixel at most. Bits are a logarithmic scale, and 0.3 is a very small amount. In fact, this value is so small that the difference between the original pixel value and the compressed value is always strictly smaller than the noise. But the usual lossy vs lossless dualism does not tell the whole story for our solution.

For example, if you take two identical pictures, one after the other, they will not be bit-for-bit an exact replica of each other and the noise structure will be different, but they are still the same picture. Similarly, Rawsie guarantees that the difference between the original and compressed photo is smaller than the natural difference between two "identical" photos.

By stating "preserving full raw quality and resolution" we mean that we preserve details, dynamic range and fidelity of a raw file, i.e. all raw parameters you normally want to tweak in your raw images in a photo editing software are still available and fully supported in Rawsie-compressed images and we don't change bit count of your image.

Boris, our head of product, reports 85.3% as our all-time record in this product. We achieve much higher values in our custom b2b solutions.

Unlike most compression algorithms, Rawsie guarantees not the fixed compression ratio, but the highest compression ratio for a particular image from a particular sensor at the highest quality of that image.
This means, for example, that information rich images, for example from drones, will have a lower ratio.

It is a common practice: as you probably know, Lr or C1 need to have camera model to be integrated into the software before we can use it.

We prioritize our camera support backlog based on upvotes on our website combined with camera market analysis among professional photographers from our partners. We do our best to add at least one new camera a month, sometimes combining them into a single software update.

We use open format DNG that can be read by most photo editing and archival software. Your regular camera raw formats are proprietary, potentially we can integrate Dotphoton's compression in most proprietary formats, with up to double the compression ratio, but only in the framework of an official collaboration with manufacturers, hopefully, in the nearest future.

In the past, this would have been a fair assumption. But as it turns out, in recent years, sensors have improved so much that they are close to being sensitive to single photons. The result is that most of those example 100MB of your image consist of quantum noise, which can be carefully removed with minimum effect to the image quality.

As mentioned above, we reencode optimized image data into open format DNG. This last part relies on ADNGC processes as Adobe is the author of DNG format. We are planning to develop our own converter as soon as possible.

Not at all. DNG can embed JPEG data, but JPEG quality is far from sufficient for post-processing photos.

We do something different: our DNGs embed the raw Bayer data. We reuse some of the infrastructure for DNG Bayer compression to implement our own compression in a way that is compatible with most implementations of DNG.

DNG is an open format and can be read by most photo editing and archival software. Potentially we can integrate Dotphoton's compression in most proprietary formats, with up to double the compression ratio, but only in the framework of an official collaboration with manufacturers.

You can either purchase a perpetual license or subscribe for a year, please see current pricing here. There is also a free version where you can use DPR for 30 images a day.
We do not charge for the amount of disk space saved as our core mission is to allow photographers forget about numbers.

We realize Rawsie is a new thing on the market and we want to provide a flexible way for photographers to give it a try without paying too much. On the other hand, recent subscription pricing experiments on the photography market had a negative impact on people's trust in subscription. That's why we prefer to have both options.

Nothing will happen: the optimized images are stored in the directories where you've put it under your full control. You will just be unable to optimize more new files.

Yes, all licenses will work for two machines: e.g. your travel laptop and your office iMac.

Yes, we are working on it. Thing is, our core target audience is wedding photographers and MacOS has been enjoying the biggest share in this industry recently. You can now apply for PC version pre-order here.
