TIFF to DNG conversion - how?

I have the Lightroom 3 Beta and i tried to convert 16-bit TIFF files to DNG. It says that it's not possible. Why is that? I really want to use the excellent compression capabilities of the DNG format. Any useful insights on this issue?
Thanks,
jj

DNG files are themselves TIFF files, with the compression method as a speciality. There are many other aspects relating to a "negative" image, which are not present in normal TIFF files, but the format is still TIFF.
You mentioned the excellent compression capabilities of the DNG format. The compression method used in the "standard DNG" is the one of the original lossless JPEG encoding, which is a pretty useless method on its own, it has been effectively dropped already. However, it turned out to be an excellent method for the non-demosaiced data if used abusively. You would not be very happy with this method if you used it on demosaiced data.

Converting Tiff to DNG

I use a Nikon slide scanner that produces tiff format files. I want to import them into Lightroom as DNG files. The Lightroom import function does not let you do this, as it only seems to let you do DNG conversions on Raw files. How do I get my tiff files to DNG format.
Sorry if this has been asked and answered, but I could not find any search function on this forum.

I had a similar problem. I had three Kodak pcd disks. I converted the 4MB pcd's to tiff using Easy graphic converter resulting in a 18MB tiff file and then to a dng. The dng's were 11 MB! To do the last conversion I had to do the last conversion in the same folder and then outside of lightroom delete the tiff's.

DNG conversions not opening

I dusted off an old Toshiba laptop that has a copy of CS4 Photoshop and the newest DNG Conversion software (v8.8). Pointed the DNG at a folder of RAW files (Olympus ORF), converted them, opened them in ACR and saved the files that are now .dng files in Bridge...but CS4 won't open them, says it doesn't support this file type. How can Adobe Photoshop not open an Adobe file type? I thought DNG made all RAW files backward compatible for Photoshop going back to the beginning of time. Any ideas, suggestions, solutions?

I got a couple of sample raws and converted them on the mac side using the 8.8 dng converter and they seem to open on both photoshop cs4 on mac and windows xp
Did you check to make sure both your photoshop cs4 versions have camera raw installed and are updated to camera raw 5.7?

Did my NEF to DNG conversion work properly?

I had read that when I convert to DNG in Lightroom (v4), the file sizes will drop by about 20% (I checked the check box for compression). I'm converting from a batch of 16-bit NEFs I created when scanning slides using the Nikon LS-5000 scanner. Those scans and files were created with Nikon Scan 4.0. After doing the conversion in Lightroom, the DNG file sizes are around 3MB-17MB. The original NEF files were about 135MB. Where in the world did all my data go? I'm concerned that the conversion to DNG threw away a ton of the original data. How is that much of a reduction possible? I'm hoping that there wasn't some catastrophic problem during the conversion, as I also checked the check box to delete the originals after the conversion is finished.
The image quality seems to be okay when looking at the DNG files in Lightroom.
Thanks,
Jay

I scanned at the full resolution (4000dpi, I think) of the LS-5000. The DNGs all appear to have their full original resolution, 5782x3946. This was one of the first things I thought about, too, but the resolution doesn't appear to have been changed any.
Jeff, upon re-opening the Convert Photo to DNG dialog box, I see that I did check "Use Lossy Compression." I spaced. I belived I was telling it to use lossless compression (I was assuming that no compression would have been used otherwise). So the conversion makes them into a high-quality JPEG, basically (but still 16-bit)? If I don't check that, will the DNG conversion use lossless compression, or no compression at all?
These slides are from a few decades to several decades old, all shot by my dad. I'm wondering if I would even see any degradation from using the lossy compression option. 135MB per image seems WAY beyond what is necessary to maintain the quality of these slides, so I would like SOME compression, but don't want to see any clearly visible signs of quality loss. Any words of wisdom welcome.

DNG Conversion - preview size

In lightroom when converting files to DNG on the pop-up screen is the Choice: Size of the Preview file: Large, Medium or Do not create.
1. what is the file size for large and medium?
2. What is the impact of NOT creating a preview? When I've tested NOT creating a file I can still open the file in my lightroom grid and loupe view. I can also view it in Windows vista Preview when right clicking on the image file on my hard drive.
3. Where do these "Previews" come into play?
4. Also, I have noticed that if I convert a JPEG file to DNG the file size is about 4x larger. Should I reserve DNG for only my raw files such as my .mrw and .cr2? Has anyone else observed an increase in file size after DNG conversion?
5. What is the deal with DNG anyway? I havn't seen the big manufactures like Canon with the new EOS-1D Mark IV and Nikon's new D3s,include the DNG as a file format selection on their cameras. What do they know that I don't, about DNG?

1. what is the file size for large and medium?
Medium is screen sized, the other option is full sized, not large.
2. What is the impact of NOT creating a preview? When I've tested NOT creating a file I can still open the file in my lightroom grid and loupe view. I can also view it in Windows vista Preview when right clicking on the image file on my hard drive.
Lightroom generates it's own preview. It's just handy for portability, so how the file looks is available to programs that can't understand the internal settings.
3. Where do these "Previews" come into play?
Lightroom will use them in Library intially. Like I said above, it's handy for other programs for managing and printing with the Lightroom settings, especially with a full sized preview.
4. Also, I have noticed that if I convert a JPEG file to DNG the file size is about 4x larger. Should I reserve DNG for only my raw files such as my .mrw and .cr2? Has anyone else observed an increase in file size after DNG conversion?
You should. The JPEG doesn't get converted to a Raw, it's just convenient to have all DNG. The increase happens because Lightroom removes the JPG compression AFAIK.
5. What is the deal with DNG anyway? I havn't seen the big manufactures like Canon with the new EOS-1D Mark IV and Nikon's new D3s,include the DNG as a file format selection on their cameras. What do they know that I don't, about DNG?
Nikon and Canon have proprietary information in their Raw files. Yes it's rather a pain when they release a new camera. Sticking to a DNG format would really help with this, if they came on board. DNG is just a way of providing a common Raw format.

I am on windows 8 platform, i used adobe elements to work on my image - the output is in dng format, how do i convert this to jpg format?

When you make a DNG that's like making another raw file, so you will need to convert the DNG file just like your original raw. Don't use the Save button in the raw converter. That's just a link to the DNG converter. Normally you would click Open instead and then save in the editor as a jpg or other image format of your choice.

File Sender, Content Conversion - how to define variable length last field?

XI 3.0 SP17
With a File Sender communication channel, that uses Content Conversion - how do I define a 'variable length' last field?
The scenario - the input file has four fields, of which the first three are a known fixed length, and the last (fourth, trailing) field is variable in length.
Using a Message Protocol of 'File Content Conversion', how do I define that last variable length field (field name 'WOData' below) in the Content Conversion Parameters section?
My current parameters are:
Recordset Structure - Row,*
ignoreRecordsetName - true
Row.fieldFixedLengths - 1,12,5,99999
Row.fieldNames - WOType,WONum,WOLine,WOData
I've tried the following for 'Row.fieldFixedLengths' to no avail -
'1,12,5,*'
'1,12,5,0'
'1,12,5,'
'1,12,5'
The last two were grasping at straws )
The only thing I've got to work is specifying a 'large' value for the final field (99999 above).
In addition, does anyone know if specifying a large value (e.g. 99999) for the final trailing field will give rise to performance issues when the file is being processed?
In the help for "Converting File Content in a Sender Adapter", it states -
<Begin Quote>
NameA.fieldFixedLengths
If you make a specification here, the system expects a character string that contains the lengths of the structure columns as arguments separated by commas.
If you also specify a separator for the columns, you must not add its length to the length of the columns.
This entry is mandatory if you have not made an entry for NameA.fieldSeparator.

<< note that fieldFixedLengths will not take any wildcard entries like *. So in these case it is ideal to provide a maximum char length. But note that while the file is being created that many spaces will be created in your file !!! >>

Yes, no wildcard is the conclusion I came to, hence my maximum )

DNG Conversion Fails in Camera Download

I've been using Photoshop CS4, Bridge and ACR for about a year. I was sold on the Adobe rationale for converting to DNG and have been doing so using the convenient check box on the Photodownloader screen. It has worked fine the entire time - until now. Suddenly that no longer works: although the DNG conversion box is checked Bridge only downloads the raw NEF files and reports at the end that it the DNG conversion failed on all of the photos that were downloaded.
So - here is what I've tried:
- Rebooted my Windows XP computer ( dual core - which has 4GB of RAM). Same results - no conversion
- Reinstalled Photoshop CS4 - and everything on the disk. Same results - no conversion
- Downloaded version 5.7 of Camera Raw (just found out there is a 5.9). However that seems to only update camera profiles - and doesn't change the version that displays on the Camera Raw preferences menu: 5.0.0.178. Same results - no conversion.
- Finally I downloaded the free DNG converter. It works, but I would much prefer to have the download program work
Any clues to solving this will be greatly appreciated.

That proves you did not install 5.7 correctly and you failed to remove the old 5.0 plug-in.

LR and DNG conversions from NEF

Just received a batch of Nefs and corresponding dng conversions from a client. I immediately noticed that there was a serious white balance difference between these pairs--LR shows the Nefs at 5600 and the dngs at 7100. Is this typical. I have worked with dngs a few times, but this is the first set of images that I have seen with side by side conversions. Is this typical? Neither the dngs or nefs have been previously edited. I don't normally work with dngs--only when a customer insists.
Very curious about this WB difference. Any explanations from the color gurus here? TIA

I was aware that the numbers were relative and would likely be different, but in this case the images are visibly very different--I just gave the numbers to indicate what LR saw them as. When the difference is between 5600 (NEF) and 7100 (dng) one sees a big difference between the cool NEF and the warm dng on the screen. This difference is seen systematically in a batch of about 75 images. LR shows no metadata differences except the WB reading. Could this have resulted from a dng conversion in an older dng converter?

DNG conversion fails sporadically with Get Photos From Camera

Camera: Canon 40D and 5D
XP SP2
CS3
Bridge 2.1.1.9
ACR 4.4.1
DNG Converter 4.3.1
Importing my files to Bridge using the Get Photos from Camera (GPFC) option results in sporadic DNG conversion failure. There's no pattern, just a lump of files that don't get converted at the end of the process. It's very frustrating because I have to manually go back and find the files that failed and use GPFC option again. Even then sometimes it fails again!
I'm attached to using the GPFC option instead of the standalone DNG converter because GPFC lets me automatically make a backup file to another disk and adds a template. But even when I use DNG Converter to import the files off my card, DNG fails for some of the files. Purging the cache only works half the time and for some of the files.
Is there any solution to the GPFC problem? I've seen people have similar problems, but with no real conclusions...
Any ideas? Thanks in advance.

Ramon,
No, I have tried purging/refreshing before and it doesn't help, because the un-converted CR2 files are just skipped over and put in the same destination folder as the successfully converted CR2 files (to DNG). I thought it might be a memory issue, but I never have any other applications open. As a test, I purposely opened some other applications to see if MORE CR2 files would be skipped, but the amount of files skipped was still random.
My "DNG Conversion Settings," accessed through the Get Photos From Camera dialogue, is set to:
Jpeg Preview: Medium Size
Compressed (Checked)
Preserve Raw Image (Checked)
Embed Original Raw File (UN CHECKED)
Could some of my Edit>Preferences>Cache options be overloading things and causing skips? I use the default settings because I wasn't confident with messing around with the cache.
Thanks

DNG conversion fail and Photoshop will not open my NEF files (Newbie question)

Two part question. First, I just recently installed photoshop CS4 to my (windows vista) computer and I go to upload NEF photos to bridge and I check the box that says "Convert to DNG" and when it finishs uploading it says "Files successfully copied, However, DNG conversion failed." It says it everytime and I don't know what to do about that.
Second part: I try to open my NEF files in photoshop it says "Could not complete your request because it is not the right type of document." I am using a Nikon D90 and I don't know if that has anything to do with this. I apologize if this question is in the wrong forum, I am new to this and I thought maybe camera raw had something to do with this at least.
Thanks for any help

You need to update your Camera Raw plug-in to either version 5.2 or 5.3RC, as well as the new DNG converter. They are available on the Adobe download page, and there are complete instructions for installation available there.

Embed Original Option for DNG Conversion

I have switched over my digital workflow now to DNG. I would love to see Adobe add an option to embed the original RAW file to it's DNG conversion in Lightroom. I was hoping that someone from Adobe would read this and take this suggestion into consideration...if not in v1.1, maybe in a future version. Thank You!

Ok, I am a novice here, but I am wondering:
What is the advantage to embed the original RAW into a DNG?
I believe I understand the value of the DNG: that it provides a single format for RAW data that simplifies the job software needs to do to render the RAW data, rather than needing to translate a zillion file formats. Also it removes the need for sidecar XMP files. OK, that sounds like good things.
So, assuming one already has a good backup of the RAW stowed away somewhere, and also assuming that the RAW-to-DNG converter is competant to do what it is supposed to, Why would one want the RAW embedded in the DNG?
One other question: would embedding the RAW file double the size of the DNG?
Thanks

"There was not enough memory" error, DNG conversion.

I have CS4 and I like to convert my files to dng, however, I can't seem to do it on multiple raw files, because after fifty or so, I get the message, Incomplete because 'There was not enough memory.'
I originally thought this may have had something to do with Bridge and trying to save way too many files through acr in bridge, since bridge is a bit of a ram hog at times and has cache issues, so I tried using the Adobe DNG Converter standalone application, and the same thing happened.
I am trying to convert just over a thousand images, NEF, about 15M each. I have several hundred gigs of HD space, GeForce 8600GT video, 2G ram, WinXP SP2.
I track my actual memory usage and adobe dng converter has never used more than 6MB of memory.
Anyone know why I can't convert my files?

I want to try to reproduce this problem, a few questions...
Which version of the DNG converter did you use (the latest is 5.5)?
What camera produced the NEFs?
What NEF settings did you use, if any, compressed, uncompressed, 14-bit, etc.?
What DNG conversion settings did you use?
Did the NEFs already have settings (XMP sidecar files?). If you did have settings, what kind of settings, just basic adjustments, or did the settings also include localized corrections, spot heals, etc.?
Thanks,
David

Right click on the email in the left hand pane. Select Mark as Unread to return it to an unread state. Click Delete to move it to the trash or file it in a folder if you have any configured. You may need to click the show button on the upper left hand side of the window to see your folders. The + sign at the bottom of that pane allows you to add a new folder.

RAW to DNG & TIFF to DNG

I have a Fujifilm IS100. I would like to convert RAW to DNG and TIFF to DNG. Could someone advise me what software I would need to do this.
I presently have have Lightroom 3.6 and Elements 4 (I am sure you can see I am on a really tight budget), when I export DNG from Lightroom it ends up in My Pictures as a PSD file, I open it and it opens in Elements 4. I have deleted Elements 4 and the PSD file will not open at all. Do I need another package other than Lightroom, like Elements 11?
Barry Patman

Ian, the answer to the second portion of your query: after you've opened
the image in the Raw Converter and made your adjustments, select the choice
"Open" rather than "Save" at the bottom right. This takes you directly into
the main Editor screen, where you can then save as JPEG, TIFF, and a variety
of other formats. That Save in the RAW converter is a new feature in PE 4,
and I ran into the same dilemma.
Regarding the JPEG that comes along with the RAW, can you open it and see
whether it's a full-size image? It could be a thumbnail. On the other
hand, as Colin suggested, your camera may have a mode that creates an
'embedded' JPEG when shooting in RAW. My Canon's do that.
