NEF to DNG 6.5 results in different number of unique colors, pixels and RGB values

I took pictures from my old Nikon D40. I converted them with the standard settings from NEF to DNG.
I then used UFRAW under Linux and saw that the pixel size increased from 3039x2040 in NEF to 3040x2040 in the DNG - and that the live view RGB values were about 5% higher for NEF that for DNG.
"FastStone Image Viewer" shows the same increase in pixel size. Additionally, it shows that the DNG has roughly 93,000 unique colors compare to 90,000 for the NEF file.
More pixel, different RGB values, different counted unique colors - what's going on here? This doesn't look like a 1:1 conversion?

Not exactly sure what you're comparing. For raw data you need to be comparing the original mosaic data values (not some converted result, or even partially converted result like demosaiced result). Are you sure that's what you're doing?

Mysql query returns different number of records from coldfusion and navicat

Hi
I'm hoping that someone can suggest a basic strategy to debug this.
I have a fairly large and complicated query that is executed by a function in a cfc.
It returns (for example) 100 rows.
If I use cfdump and then copy and paste the SQL of the query (with the variables, of course) into Navicat and execute exactly the same query on the same mySQL database, it returns 130 rows.
Same SQL string, same database, same data - the only difference is that in one instance Navicat submits the query and in the other, Coldfusion does.
Has anyone ever had anything like this happen before?

Ok I found my own bug. Of *course* the sql queries were not identical.. they could not possibly have been. My mistake was thinking that they were.
The problem was part of the WHERE clause:
AND orderid in (500,503,505)
In the coldfusion code this was
AND orderid in (<cfqueryparam cfsqltype="cf_sql_varchar" value="#lstOrderID#">)
which of course rendered in mySQL as AND orderid in ('500,503,505')
This was not immediately apparent as the cfdump returns this as AND orderid in (?) with the variable in the array below.

SD extractors - different number of records in RSA3 and in the table MC*

Hi
After deleting setup tables and creating it again
for extractor 2LIS_11_VAITM
I have
in RSA3 - 64686 records
but
in MC11VA0ITMSETUP structure only 14857.
The same situation is for 2LIS_11_VASTI.
Where this difference is getting from?
Thanks
PWnuk

The reason is that the MC* setup tables "cluster" the data, so there is not a 1 to 1 match in record count. Therefore, you shouldn't validate using record counts between the setup tables and RSA3.
See these links:

Error 200524 Different number of channels in task and data

Anyone out there with some information would be greatly appreciated. I have attached my VI. Essentially I am trying to build a simple PID VI to controll the temperature of a piece of equipment in a system I am building. I have heating wire powered by 120 V source. The circuit is controlled by a simple relay, which is controlled by a digital line on my NI USB 6343 board. I have seen numerous examples throughout the forums and the shipped examples, but I cannot seem to figure out how the PID VIs work. I understand the basics of a PID controller, but cannot make the connections of how to actually get it to work in LV.
I figured that this VI I wrote is pretty simple and should work, but I keep getting this error.
Error -200524 occurred at PID_v0.vi:Instance:19:1
Possible reason(s):
Write cannot be performed, because the number of channels in the data does not match the number of channels in the task.
When writing, supply data for all channels in the task. Alternatively, modify the task to contain the same number of channels as the data written.
Number of Channels in Task: 1
Number of Channels in Data&colon; 1000
Task Name: _unnamedTask<1>"
Any advice, direction, sample VIs that are not overly complicated, etc would be greatly appreciated.

Hi andyabs,
I'm not getting the same error you are when running this VI. How are you setting up your channels and tasks in the DAQ Assistants? It seems like this may be the source of your error.
You should also take a look at Section 4 of the attached White Paper. Using DAQmx functions rather than the DAQ Assistant will give you a bit more functionality with your program. Let me know if you have any questions about this example.

Any benefit to convert NEF to DNG

Does anyone convert their NEF (D300 in my case) files to Adobe DNG and then start their workflow?
Or are the NEF's just imported into Aperture and then adjustments are made?
I use Aperture now for a long time. I usually just import the NEF files. I've been using Photoshop CS4 to learn it and have just been sending the NEF file within Aperture to Photoshop. And of course it comes back to Aperture as a PSD file.
I ask because Aperture has a tendency to lag making adjustments. But I noticed Aperture doesn't lag if I make adjustments on the PSD file or a DNG file. Adjustments are in real time.
So I'm thinking of converting my NEF's as the first step of my work flow. Then import the DNG's into Aperture.
I have all of the NIK Software and working with this in Photoshop is 1000% easier in Photoshop than Aperture.
I can't seem to tell any degrading of the NEF converted to DNG. I've done a few now and compare. I can't seem to tell. Pre or post adjustments made in Aperture.
Thanks for any thoughts or opinions.

DNG is just Adobe's proprietary attempt to sell the world on using Adobe's RAW conversion format ("DNG," the result of converting camera makers' individual RAW files using Adobe Camera Raw, "ACR"). Adobe benefited greatly with PDF and wants to do the same with RAW DSLR capture.
DNG is not better. In fact most folks (at least the ones not already sleeping with Adobe) will most often find conversions by Aperture and/or individual camera vendors' converters (like NX2) to be visually better than ACR to DNG. However differences among converters are usually slight enough anyway to make RAW-conversion quality irrelevant when compared to workflow.
The conversion of RAW data is different for each individual camera, no RAW converter is best for all cameras, and the results of conversion are a matter of individual taste in any event.
Note that most camera vendors keep RAW algorithms and protocols very secret, so folks like Adobe and Apple do a lot of deduction (some say speculation) when building each camera's RAW converter based on imperfect information. That is why most folks consider Nikon's conversions of NEF files "best;" but unfortunately Nikon's workflow is atrocious.
...is there any significant advantage to converting (to DNG)?
No, there is significant disadvantage in converting NEF to DNG. You would be seriously disrupting Aperture's workflow just to achieve what most folks consider to be less-good RAW conversions.
Some photogs do find significant advantage in first using NX2 to convert Nikon NEF files to TIFF. Others find the differences from Aperture small enough not to justify the weight of the NX2 workflow.
I read the Adobe site regarding how DNG is more a standard then NEF or any proprietary camera file.
That is just disgusting Adobe marketing BS. Nikon was around supporting standards like their lens mount for decades before Adobe even existed. Even if Nikon self-destructed today there will always be plenty of RAW converters for the billions of NEF files already created.
Of course Adobe would love it if the world lowered their standards to some Adobe-defined lowest common denominator, but then we would probably not see the various consistently fast tech advances like the low light performance of the Nikon D3.

Unable to see converted NEF to DNG files in Photoshop CS

Aloha, my laptop recently crashed and I am in the midst of trying to restore my laptop to the way it was. I am using Photoshop CS and back in December 2009 I downloaded DNG converter. I am using a Nikon D90, shooting in RAW. I don't recall what I did after downloading the DNG converter but I was able to convert the NEF files to DNG by simpling clicking on the DNG icon, selecting the file and click convert and the NEF were converted to DNG files. I was able to use my Photoshop CS with these covverted files. In the restoration of my laptop, I loaded my Photoshop CS program and then did a search on-line for the DNG converter. I found a 5.6 version and later a 6.3 version. I first downloaded the 5.6 version. I then clicked on the icon, selected the files and click convert. I can see the NEF photos being converted. However, when I went into my Photoshop CS program, I did not see any DNG files even though I saw the files being converted. I downloaded the 6.3 version and got the same results. I also went into Change Preference and selected Camera Raw 2.4 and later. But I though I am seeing the files being converted to DNG, I do not see any of those converted photos in my Photoshop CS program. Can anyone help me? Am I missing a step or two? I would appreciate y'all expertise in this matter. Also, anyone knows how to uninstall one of these DNG converters I downloaded? Thank you very much, Ron

Aloha Jim,
I went on Google and typed in DNG 6.3 converter. The following appears:

I click on the proceed to download. The follow appears.

I assume I'm supposed click on this icon that looks like three stacks of

come on a window that says, Camera_Raw_6_3_updater.zip - WinRAR (evaluation

third folder says, payloads and the last is like a window, rectangular in
shape, white at the bottom 3/4 and the top portion is blue. It is labeled

click it and then it looks like it is updating something, then a window that
says, Adobe Application Manger comes on which says, some updates failed to
install. Another messages says, update is not applicable. I don't recall
what I did next...tried other things but I finally got the icon (circular,
the top 1/3 white with 4 red letters, the bottom 2/3 greenish with a blue
arrow pointing down. It is labeled as DNGConverter_6_3. I clicked this
icon and get this open file - security warning window. It states, the

button I then get an error message saying, Installer integrity -check has
failed. Common causes include incomplete download and damaged media.
Contact the installer's author to obtain a new copy. More information at:

I don't know what to do. Back in December of 2009, all I did was downloaded
the DNG file that I found on Google, click on the DNG icon, and my NEF were
converted so I could see it in my Photoshop CS.
Am I doing anything wrong. I would prefer not to invest $200 for Photoshop
CS5 since Photoshop CS along with DNG converter were meeting my needs. I
know it may take some time to write this but perhaps could you write down
the step by step process you would do from searching for the DNG converter,
selecting the converter, downloading the converter, activate it so
everything is set up for use with the Photoshop CS. I would appreciate it
very much. It has been very frustrating and time consuming in trying to
resolve this issue. I thought it would be so simple setting it up like the
first time when I first installed it.
Thanks again for responding to this matter. I appreciate it very much.

I'm having troubles converting my raw files from Nikon D5200 (NEF) to DNG. I tried using Lightroom 4, but it didn't identify the folder containing the files. So i downloaded the latest DNG converter but that too didn't identify the files kept in the folde

I'm having troubles converting my raw files from Nikon D5200 (NEF) to DNG. I tried using Lightroom 4, but it didn't identify the folder containing the files. So i downloaded the latest DNG converter but that too didn't identify the files kept in the folder location. So I downloaded DNG converter v7.3 for D5200. It identifies the folder and files; but it is giving me parsing error on trying to convert files. I'm running Windows Vista Home Edition SP1. Kindly advise. Thank you.

I probably missed this detail in what you’ve posted, but do you see the thumbnails of the three cameras’ raw files in Finder if you don’t convert to DNG?
What has happened in the past is that the Apple raw interpreter doesn’t read thumbnails of DNGs it doesn’t like, where at least one thing it didn’t used to like was embedded lens corrections for mirrorless cameras. Are the Olympus and Panasonic mirrorless—meaning there is no optical viewfinder and everything is seen on an LCD screen or perhaps an electronic view finder? If so the reason these are different is that the camera is doing the lens distortion corrections automatically and this information is stored in the raw files and in the DNGs but Apple doesn’t know how to use these embedded lens corrections or doesn’t know how to read the newer DNG spec that does allow for this information to be embedded in the DNG, at least.
Apple could just extract the embedded jpg preview and ignore the other parts of the file it doesn’t understand, but it apparently doesn’t do this.
What I’m not sure about is if the Apple raw interpreter still has this problem or if you’re on an older system without the latest updates for camera raw decoding by Apple.

System or program crashes when converting from NEF to DNG

Hello Adobe.
First off, I love your software.
Second, this is my concern. You guys are pushing DNG as the go to raw format. That would be great if it worked good, but it doesn't.
First, when I convert from my Nikon NEF format (Nikon D7100) it chugs along just fine, then suddenly crashes either the program or my system after converting 50-100 or so images.
I have tried everything from downloading your software again, to turning off everything other then what is needed to do the conversion.
Of course I have the latest DNG utility/plug in/drivers from your website.
Second, the DNG images open much slower then my NEF images. Plus when I view them in Windoze file system view and want to see the photos in extra large icons, it renders the images very slowly.
My system is Windoze 8.1 updated always, Photoshop CC latest and greatest (I'm in the rental program), Bridge and Lightroom.
I have tried to use bridge and lightroom to do the conversion, even a separate utility and the crashing still happens. All these are up to date.
My system has an i7 Intel processor, 16 gb of Kingston ram, an ASUS P8Z77 MPRO mother board and a good stable power supply.
No other software crashes my system like converting from NEF to DNG.
What I do notice is my CPU fan goes into high RPM's and I am wondering if the CPU is overheating causing this.
If that is the case, then it would seem to me the conversion software is taxing the system far more then it should since my system is no slouch and while it isn't the latest and greatest, I would consider it to be in the top 20%,
it should be able to handle the conversion with no problem.
Are you aware of problems with the DNG software and or file format?
Is their any information I could forward to you to help solve the problem?

Photoshop Help | Digital Negative (DNG) - Adobe
helpx.adobe.com/photoshop/digital-negative.html
DNG is a publicly available archival format for storing camera raw files. Adobe provides Adobe DNG Converter, a free utility that converts files from more than ...
That is off the net, therefore, Adobe looks at DNG as part of Adobe Photoshop, which it is if a person chooses to convert.
My issue has to do with it crashing, both my system and software.
I assume if people here are using it, then they can advise me if they are having similar problems.
I have also written Adobe directly several times over the last month and have yet to receive a response.
I apologize that I posted here, but since I consider DNG an integral part of Photoshop, then I think it is appropriate here.
I was also not aware of a DNG forum, if one exists.
Thank you for your assistance.

Exposure to the right results in different TRC than normal exposure

Exposure to the right is advocated by most experts to improve tonality and dynamic range. On the Luminous Landscape a photographer noted that ETTR all the way to the right followed by negative exposure correction in ACR produces a different image than is produced by normal exposure, and that he preferred the latter image.
Luminous Landscape Thread
Most responders to this post postulated that, since ACR is operating on linear data, underexposure by 1 EV followed by a 1 EV boost in ACR would produce the same results.
I had some exposures of a Stouffer step wedge. The first was exposed so that step 1 has a pixel value of 250 when converted with ACR at default settings into aRGB. This is exposed to the right as far as possible. A second exposure placed the same step at 221, and this step was brought back to 250 in ACR, which required an exposure compensation of +1.05 EV.
If you compare the resultant images in Photoshop using the difference blending mode, the differences too dark to make out on the screen, but can be detected with the eye dropper. In this image, normal exposure to the right is on top, and the difference between normal exposure and underexposure followed by a boost of 1 EV in ACR is shown on the bottom.
The different resulting tone response curves are better shown by Imatest plots of the two images. As is evident the TRCs are different, contrary to my expectation. Comments are invited.

The ETTR Myth
ETTR is short for expose to the right. Some folks have promoted it as a replacement for traditional exposure metering. The premise is that you can validate camera metering by simply reading the histogram in the cameras preview window.
Unfortunately, it is based on some basic misunderstandings about digital photographic technology. The first misunderstanding is the premise that each bit level in a digitally encoded image represents an exposure stop. The second misunderstanding is the premise that all digital cameras capture light in a perfectly linear fashion. The third misunderstanding is the premise that the histogram represents the raw image data captured by the camera. I will briefly address each of these.
Any correlation between exposure stops and digital bit levels can only be accidental at best. The total exposure range in a scene or an image is correctly known as the dynamic range. The dynamic range of digital cameras is wider than most folks assumes and usually equal to or better than film or paper. It can be defined in terms of tone density, decibels, or exposure stops. It is a function of the optics and sensor electronics in the camera. The few cases where an accurate range is provided by the vendors, it varies from 8 to 12 f/stops.
The image data is converted from analog measurements by the analog/digital (A/D) circuits early in the capture. This can wind up as an 8-bit, 12-bit, 14-bit, or even 16-bit digital value depending on the camera and its user settings. It is simply a number that has been digitized. Any correlation between bits and exposure levels is pure speculation, end of subject.
Second, the digital capture of light is not strictly linear. It is true that the silicon sensor itself will capture light in a very linear fashion. But this ignores reciprocity at the toe and heel of the extremes, the quantum efficiency of the substrate, and most importantly it ignores the optical filters in front of the sensor. If the color filter array were linear it would be impossible to reconstruct colors. And these are not the only optical filters in your camera. Then, the A/D circuits have gain controls based on the current ISO setting. And some A/D circuits perform some pre-processing based on the illuminant color temperature (white balance) and limited noise reduction based on the ISO setting. The point is that there are many steps in the pipeline that can introduce non-linearity.
Finally, the image in the preview window has been color rendered and re-sampled down to a small size. This is the data shown in the histogram. The camera can capture all colors in the spectrum, but the rendered image is limited to the gamut of an RGB color space. So, in addition to exposure clipping the histogram will include gamut clipping. This is also true for the blinking highlight and shadow tools. This might imply an exposure problem when none exists. There is no practical way to map all the data in a raw image into a histogram that you could use effectively in the preview window.
If you capture an image of a gray scale chart that fits within the dynamic range of the camera, at the right exposure, you can create a linear graph of the raw data. But if you underexpose or overexpose this same image, the graph will not be linear and it is unlikely that software will be able to restore true linearity. End of subject.
If you typically shoot JPG format, the histogram will accurately represent the image data. But clipping can still be from either gamut or exposure limits. If you typically shoot RAW format, the cameras histogram is only an approximation of what the final rendered image might look like. There is a significant amount of latitude provided by the RAW image editor. This is probably why you are shooting RAW in the first place.
So, in closing, I am not saying that histograms are bad. They are part of a wonderful toolkit of digital image processing tools. I am saying ETTR is not a replacement for exposure metering. If you understand what the tone and color range of the scene is, you can evaluate the histogram much better. And if you master traditional photographic metering, you will capture it more accurately more often.
I hope this clears up my previous statements on this subject. And I hope it explains why I think ETTR and linear capture are based more on technical theology than on technical fact.
Cheers, Rags :-)

The risk analysis results are different when choose report type as "summary" and "management" summary

Hello experts,
I found a expired user with SOD conflicts in "management summary" report format, but it doesn't exist in "Summary" report. You can find the screenshot in attached file. The user name is "YINPENG2_BK".
What happened? The result of different report formats are from different data source?
Sincerely yours,
Lynn

Hi Lynn,
that's not an issue from the system. It's more a handling issue as the results are splitted into several result sets. In management summary view you have only one result set as it's grouped by user and risk, whereas you have more than one in summary view (as you have multple entries for each user and risk).
Change to the second, third, etc. result set and you will see the user in the list:

Different EvDre results in different PC

Hi,
my question is very simple but it makes me fool.
I build new report with EvDre, but the results are different when we lunch it in different personal computer.
For example, in my PC (logged in with my user and password) I return my values. In an other PC, logged in with the same user, EvDre report gives me no results.
How can I resolve it?
Thanks in advance.

PLease include your version when posting; Assuming you are using BPC 7.0, the first test I would run on the PC that is not returning the values under the same ID as the first PC, is a Report Wizard report. DO those 2 reports match in values? So if you run a trend report on both PC's using the exact same point-of-view from the Action Pane member settings, do you get the same values?
Then create a simple EVDRE report and test results for both PC's.
If that doesn't work, the next thing to do is run from BPC for Excel, etools, Client OPtions, Clear Local Application information. Then exit. Logging back in, please go through the Connection Wizard. Retest the wizard and the EVDRE reports.
Hope this helps.

D300 will not open as NEFS or DNG with CS2

hi,
using CS2 ( the only pshp activated on my MBP )
forgot to deactivate my home G5's.
purchased the D300
did not install its software NX or suite
did insert ACR 4.3.1 into adobe plug in
and also converted the NEF to dng
i still cannot open the files.
is it impossible to use CS2 with the D300? must i use CS3
or
what am i doing wrong?
must capture NX be installed
thanks

ACR 4.3.1 will NOT work with Photoshop CS2. The latest version that is available for Photoshop CS2 is ACR 3.7. There will not be any further updates. You need to to download and use the DNG converter, version 4.3.1. It will create DNG copies of your raw images that will open in Photoshop CS2 and ACR 3.7. Capture NX does not have to be installed to make this happen. You just need to use the most recent version of the DNG converter along with the correct version of ACR.

Lightroom 5.7 will not convert .nef to dng from my Nikon d750. Stand alone dng converter will not recognize or convert the files.

Lightroom 5.7 will not convert .nef to dng from my Nikon d750. Stand alone dng converter will not recognize or convert the files. Any know whats wrong?

I don't understand why you feel you need to use ViewNX to download your images from the camera. Lightroom has an excellent import process. I don't see that you gain anything by using the Nikon software. It seems to me that it has the capability of just creating more problems.
If you want to convert your D750 files to DNG using the standalone DNG converter thing you need to have DNG converter 8.7 installed. Once you have it installed, just choose the FOLDER in the DNG converter, but don't open it in the DNG converter file browser. If you open that folder then you will get the message that there are no files to convert. The converter works on the folder level, not the individual file level.
