I found I got nice colours so far with CS3, but I understand I'm not supposed to - the consensus is that C1 is better in this respect. The only problem with it for me is that after a DNG has been opened by CS3, it shrinks to about 6MB, even though I have lossless compression turned off in the ACR dialog, and even if I don't click on 'Save'. This means that C1 will not open that DNG in the future, and I don't want to lose the ability to come back to a file and develop it again in a different way. Consequently, I'm sticking to C1 Pro at present.

I am not having this problem. In fact, I just went back and checked DNG files I opened today in CS3, then opened them in C1 as well.....

I'm having this compression problem too. To say that it gives me the *&%$ is an understatement. I've checked everything I can find in menu's etc to stop it but no luck. Strange how some people report the problem and some don't. Anyone know someone at Adobe?

Hmm... perhaps there is a difference.... I am still using Bridge from CS2 and not the CS3 bridge, because the CS3 bridge kept locking up - and I am on a G5 MAC if that makes any difference....

I'm on a G4 mac and using Bridge CS3, but may go back to CS2 as it seems to have problems. I have not checked file sizes, but I will and report back. I can't imagine Bridge has anything to do with it, but who knows. Bridge CS2 is a complete mystery to me and I'm really hoping CS3 is a vast improvement.

I'm not sure this will cure the problem but apparently it does help many others:PSCS3 Bridge Beta 2;wow what a mouthful !

Also... The compression happens on both CS2 and CS3, if I open it through Bridge or not. I'd REALLY like to get to the bottom of this as I've posted on numerous forums and no one seems to know what to do to get rid of it. Lossless or not, I don't care for compression, especially if I can't cross back to another programe for a comparitive conversion. I'd really like to intigrate Bridge into my workflow and find C1 rather clumsy for large amounts of files.

There is a dialog box in Camera raw and sounds like folks have this on 6.3 , you can click on it and change it to the correct size. I'm in CS3 right now and i have it set for 10.3. Click on show workflow option on bottom left

Good catch Guy! I never really explored the dropdown next to "Size" in the new ACR for CS3.

I opened a RAW image form my Canon Mark II (as the battery to my new Black M8 which arrived late yesterday afternoon is charging). I digress, so I opened an image with the box set at 2336 by 3504 pixels per inch in ACR which opened in Photoshop when I went to Image> Image size gave me a file size of 46.8M. I then hit cancel.

Same image opened in ACR but in the Size dropdown I chose 3413 by 5120 pixels/inch, opened in Photoshop came out to be 100M! So if we don't choose the highest setting, I think ACR is simply throwing a lot of data away. Or am I wrong?

No not really what it is doing is uprezing the file when you chose bigger than your MPX Raw. So say the M8 is a 10 .3 mpx file (Normal) than if I chose bigger PS is just uprezing it to that file size or downsizing if you went the other way. Your standard is what the camera produces.

 

If you down size than data will be lost. Now if you have to make smaller files for a client lets say at least process normal and store those images on a hard drive than for your client just run a action to downsize them. This way you have a master set at the normal MPX that the camera can produce

Thanks for the clarification Guy. Well while searching through the different Forums I found another nifty trick. I found it very irritating that while opening a file from CS2 Bridge, it would open in CS3 instead (when I wanted it to open in CS2).

Simply open CS2 Bridge and then go to Preferences under Bridge and go to the 4th one down called "File type associations" Then use the appropriate dropdowns to select CS2.

 

To reiterate what Frank said above, if you are having problems with the Bridge in CS3, as of Jan.18th, Adobe released a beta fix. Frank has the link above.

Unfortunately, that's the first thing I tried. So, still no luck. Files still shrinking away. It's strange because they always shrink to about 6 meg first up, then each subsequent open they either grow a bit or shrink a bit. I'm assuming this is something to do with the saved JPG previews.

Tim, the Leica DNG's are uncompressed. I think the 6.x mp files you are seeing are compressed versions of these - using lossless compression. If you pass the M8 DNG files through Adobe's DNG converter and select compression you get files of this size.

Has anyone tried processing images with CS3 beta? It must have different profiles than Lightroom because the DMR files really look nice and the skin tones look very good.

 

The new black-and-white processing mode in the Bridge CS3 beta can also pull some really beautiful tones out of M8's DNGs.

 

For those who haven't tried it: the new Camera Raw has an automatic mode where it suggests a colour (filter) mix to generate a broad tonal range on conversion to B&W - you can fiddle with it for hours but I have found that in many cases the automatic setting can generate some fabulous results (and fast!) with my M8 images.

Tried the Beta Fix of Bridge 3 - works different as before the fix:

 

If you open a DNG and it has 10MP/19M from the DMR, it opens and closes without compression - stays 10MP/19M

 

If you open it with higher resolution, PS does an upres, which can be stored as a PSD file then, but if you close the file without SAVE it remains 19M/10MP, same as it was originally.

 

But also if you open with lower resolution - say 2.8MP, then it allows you to store as lower res PSD, but the DNG file after closing stays the 10MP/19M

 

FInally this seems to work now :-))

Interesting!

 

Nobody seems to be interested in proper workflow for DNG, because nobody seems to have run into these issues - I start thinking what are many of these digital Leica photographers posting in the forum intersted in, if not in RAW workflow?

 

If I would only do JPEG, I would not use a Leica, but instead either a P+S or a DSLR for less than $1000.-

Sorry Peter, are you saying we don't know what we're doing? :-)

 

I've been using CS3, but with iView not Bridge - I hope that qualifies for 'proper work flow'. Perhaps it doesn't.

 

As I mention above if you push the M8 DNG files through the Adobe DNG converter and specify _lossless_ compression you get files of around 6M. They vary because the compression depends on the content of the file. I am almost certain the same is happening above and lossless compression is being applied.
