Those pictures have quite a bit of noise, but I've also seen pretty clean 3200 shoots taken with the 7D. Shooting conditions matter, a lot.

I convert ALL of my Raw files to DNG using Adobe Bridge and save them to my hard drive. I then process them as DNG files using Lightroom 2 or photoshop.

You could, of course, just import them into your Lightroom 2 catalog first, and check the option to convert to DNG upon import. I have not opened Adobe Bridge even once since I started using Lightroom.

As has been posted Adobe has a DNG converter and if you have Lightroom 2 and above you can down load the new DNG converter and then convert the 7D raws and import them into Lightroom or even PS3 which I have done for both. In order for it to work in Lightroom you need to update Lightroom to 2.4 or higher with 2.5 being the latest available. When you click on the 7D raws a pop up window will appear and you can choose the DNG conversion once converted you can import into PS3 or Lightroom there you can PP to your hearts content.

DNG is a open sourced converter that Adobe hopes will become the standard in the raw image files of Nikon and Canon as well as all others. There is some extra loss-less compression so these DNG files are a bit smaller which is another advantage.

extra lossless compression? surely some raw data is changed is it not, if one were to analyze it in detail? anyway, is this a better way to archive originals and trash the raw files, or not?

In theory it is, but personally I wouldn't feel comfortable getting rid of the originals.


Some Canon stuff and a little bit of Yongnuo.

how does 7d work if it is not even listed? i don't get it. is it just the way it is?

Well It didnt work with the version I had Installed then I updated to the Latest and it works even though its not listed.

It is beta support that they decided to include in 5.5. There will be a follow-on release at somepoint (hopefully soon) with finalized support for the 7D.

Lossless means just that. Lossless. Or no compromises made.

I will give you an example but I am sure it works different in the real world than in my example.

You have 10,000,000 bits in a pattern some in 2's and some in 1's and 3's and 4's. Your code looks for all the 4's and cuts them from the file. Now the file is smaller. When you uncompress the file and add the 4's back it is just like it was before you took them out. Hence it is lossless. Nothing is gone forever just removed and then replaced exactly as it was before you touched it. The same thing goes on in the Canon RAW file it is just that they do it using their own proprietary code and Adobe wants to supply the code. Adobe by doing this will also have access to the prototype bodies as well so they will be in the loop from the beginning.

About DNG

This is a 7D thread, so DNG should not be the main topic, but misinformation is best corrected immediately.

DNG is a open sourced converter

1. DNG is a raw image data format, not a converter.

2. Adobe created and is maintaining a DNG converter program, the most important parts of which are not open source.

3. Adobe is maintaining a set of routines as open source code for those, who want to create or process DNG files and don't want to write everything from scratch.

There is some extra loss-less compression so these DNG files are a bit smaller which is another advantage

The compression adopted in DNG is the same as the one adopted by Canon (except for the 10D and 300D); it is the "lossless JPEG compression".

The DNG converter has more time on hand than the firmware in teh camera, thus it can optimize the compression; that makes the files somewhat smaller. The DNG file is then even smaller, because Canon creates a full-size JPEG, for example 2 MB size, and a tiny, uncompressed, 16bit thumbnail, 1.7 MB (sizes from a 7D sample). The second one is not present in the DNG, the first one can be chosen.

extra lossless compression? surely some raw data is changed is it not, if one were to analyze it in detail? anyway, is this a better way to archive originals and trash the raw files, or not?

As the image data in the DNG file is not the direct copy of the original, i.e. the data goes through decoding and encoding, there is a small danger, that something gets wrong. In fact it occured with two cameras, that the DNG converter created erroneous output. Those, who threw away the original, could not use the images even after Adobe corrected the program.

It is important to see the difference between working with DNGs and archiving DNGs instead of the native raw files.

There are two reasons to work with DNG instead of native raw:

1. if the camera is not supported by the favoured raw converter (for example if one does not want to upgrade PS only because of ACR),

2. if one favours embedding the adjustments by ACR into the raw file, versus the XMP sidecar files. ACR never changes the native raw file (DPP does!); the adjustment parameters will always be written in an XMP file. This is, how I like it, because I want to archive the adjustments as well, and I don't want to re-archive the "original" for that purpose. Others despise the extra files, want to store the adjustments physically with the raw data.

(Note: if the DNG file is "read only", then ACR creates a sidecar XMP, like with the native raw file.)

Nevertheless, the above considerations do not mean, that the native raw, the "original original" do not get archived.

I'm using CS3 also. I plan to use the Adobe DNG converter and then process the .dng files, or possibly use DPP 3.7 for the initial raw conversion, save as TIFF, then process in ACR and CS3.

I am in this situation also. Strangely the only thing that is a major problem for me (so far) is no facility to set the description field in DPP although it displays in in file->info.

You can set the description in zoombrowser but only one file at a time. This then shows up in DPP and in TIFs in Photoshop and Bridge.

I only changed to CS3 for workflow reasons and always preferred DPP output. DPP has improved a lot since I last used it 4 to 5 years ago.

So I need to decide DPP or CS4, I don't want to mess with DNGs, it only complicates the workflow defeating the whole object.

I agree the sidecar files keep backup sizes down and are much more efficient.
