Well,

the battery charged. set the camera to DNG. shot away, when I transfer the files they all come up as TIF, When I open them in PS, they come up as JPG. I am tired and don't want to play anymore now :(

Well, here is a sample that was shot in DNG, came accross as TIF and for some reason opened as JPG :bang:
 
Jorge --

Are you using Capture One software to read the DNG?

PS itself cannot read DNG files. Adobe PhotoRAW might recognize the DNG format but the Capture One (provide with the camera) is the recommended RAW (i.e., DNG) conversion software.

As for JPGs are you shooting DNG+JPG mode in the camera? If so that would be where the JPGs are coming from. If not then some program on your PC (or Mac?) is mishandling the DNG format files and barfing them up as JPGs.

I am using a Windows XP system and not having any problems...
 
Also -- how are you getting the files from the camera?

Using the USB cable?

I am using a SD card reader, not the cable.

If you are transferring directly from the camera via USB then whatever software that is handling the transfer must be mangling the DNG files.

Try an SD card reader and the Windows photo upload manager.
 
Ok, Will give it a try now. Funny thing is that the DMR shot in DNG format and PS opened them up without any problems and still does when it sees a DNG file. Give me a few minutes I will be back.
 
Ok, If I transfer the files with the USB cable they come accross as TIF even if they are recorded as DNG.

If I pull the card and use a card reader, they come accross as DNG.
 
Note to myself!

I will remember that!

This must be a setting in Windows. I don't understand why I cannot just click on the camera folder in explorer and see the DNG files with the camera ttached to the PC vias USB. They show as tif. It makes no sense. Yet if I pull the card and place it in a reader they show as DNG.

Use your card reader. Don't bother hooking up your camera to your computer, the transfer is probably too slow anyway. Your computer may have a SD slot in which case you don't even need a reader, just plug and play!

You lucky dog! If I were you I would be up all night!

There may not actually be anything wrong here. I didn't realize it until just now, but Adobe says the actual data format of DNG files is the same as the TIFF 6.0 format!

Quoting from the Adobe Digital Negative Specification document, which you can download from adobe.com:

DNG is an extension of the TIFF 6.0 format, and is compatible with the TIFF-EP standard. It is possible (but not required) for a DNG file to simultaneously comply with both the Digital Negative specification and the TIFF-EP standard.

[snip...]

This section describes the DNG format. As an extension of the TIFF 6.0 format, DNG should follow all the formatting rules for TIFF 6.0. For more information, refer to the TIFF 6.0 specification.

[snip...]

The recommended file extension for Digital Negative is ".DNG". Readers should accept either the ".DNG" or ".TIF" extensions for compatibility with TIFF-EP.

So, a DNG file can be a TIFF file, and vice-versa... and either ".DNG" or ".TIF" is an acceptable extension for them.

If Windows is trying to identify your files by reading the data out of them, it will be reading TIFF data, and this may be why it's identifying them as TIFF files. Why the files would be typed differently using a card reader, I have no idea (since I don't use Windows) but it could be that the driver that communicates with card readers (which should appear as USB Mass Storage devices) types files differently from the driver that communicates directly with the camera (which might use a different protocol such as PTP.)

I used a card reader to download the M8 files to my Mac G5.

Format came across as DNG, and was quickly read, and opened by PS CS2.

The photo transfer utility that is accessing the files via USB connection to the camera could be scanning the files and picking up the header information identifying it as TIFF. When the card is accessed by the file browser on the card it is only looking at file extensions as it would on any new volume.

It would be interesting to connect to the camera via USB without the use of any "photo utilities" in windows to see how it handles the files, but this might not be easily accomplished without disabling the photo connection app.
 
Mr Roberts,

I tried that :) Still as TIF.

Ok I understand the tif/dng thing now. but the drawback is that I cannot open with camera raw when used as a plug in.
 
Why is that Jorge? What is the CR plugin doing to the files when you access them from the card via reader instead of the camera?

Does it do the same thing when you copy the contents of the card to a working folder on your PC?

Very helpful discussion here. Leica should consider a tutorial for those of us who sometimes struggle with file types and file conversions and data management issues. (Do we sense a market opportunity here?)

I'll keep this string handy when I acquire my M8 next week.

Thanks for blazing the trail for the rest of us!

Jorge, can you explain how you eventually found your way to a solution. I'm having a similar issues where I can't get DNG files to show up in C1. Any advice would be appreciated. Thanks.

It is Windoze, you know?

I've "upgraded" my laptop's OS to Vista (RC1) and it's been a pain; I've been having to redo a number of things. I'm doing it on my laptop to see if it's worth the trouble on my main computer.

Hi All
I am shooting DNG + JPG Basic, but when connecting via USB I only get TIF files, i.e. 2 tif files with the same number but no JPG. I understand the DNG/TIF issue but why no JPG? Anybody else come across this issue? :(
CS2/CR opens the tif files fine. JPG's shot on their own are also fine.
Kind regards
Ken
PS I love the results...:)

CS2 doesn't support the DNG leica raw yet, maybe with their last update.

Use C1 for the start of your RAW workflow. After that there are a number of alternatives.
I have Aperture 1.5 as a trial version, lightzone and CS2.

I personally find that most tiffs coming out of C1 do not need any further enhancement, but this is personal of course, therefore I use Aperture for filing and the occasional "light tweak" for which it is perfect. It also saves a lot of time compare to CS2 which I only use sporadically these days for the heavy editing functions.

You can download aperture as a trial version 30 days, and then purchase it for 279$. I think it's worth the purchase price.
C1 however can become pretty expensive, I believe they also have a light edition which would be fine too.

Just thinking, I don't have a windows PC I do it all with MacPro computers, I don't know if Aperture will run on XP or Vista..... probably not. Lightzone does though for sure, but currently it's just a Beta version.

Just an update: using a card reader has eliminated the problems. The jpg's were there all the time! What is more the files are now showing as DNG as opposed to tif. Perhaps the camera USB link is only for the Leica Digital Capture?
