12- and 14-bit Raw file conversion to 16-bit tiff

Does anyone know how Camera Raw converts the 10, 12, or 14 bit RAW file data(14-bit D3 .NEF here) into the 16-bit tiff files it can produce. I assume it either manages to leave empty space in the file, or interpolates by some means. If interpolation is the answer, is it by a method analogous to one of the spatial resizing methods(nearest neighbor or bilinear)?

Keep in mind that a 16bit image format (eg, TIF) is actually a container, and I've seen many variations on putting lesser bit depths in the format. EG, 10bits may only be stored in the first 1024 bins, or the same 10bit data may instead be stored in every 6th bin - the latter of which is the most common and best way. When I look at the 16bit histogram after ACR has converted 12bit RAW to 16bit TIF, it is as if 12bits has been converted to 16bits (actually 15bits), because every bin appears to have data in it.
As to how it's actually done, it may be proprietary ... but someone else may be able to draw conclusions from the open algorithms that are available (eg, dcraw).

Raw File Conversion

What is better for Raw File conversion, Aperture or Adobe Camera Raw in PS CS2? I'd heard there was more noise in the Aperture conversions. Do people manage their photos in Aperture and export the raw file to PS for conversion if PS is better?

i agree with Paul. it depends on your Camera.
I am a photgrapher and use for most of my work now the Nikon D200. Sometimes Canon EOS-1 Ds mark II. I use Aperture 1.5 and Adobe CS2.
Now i have tested Adobe Lightroom beta4.And I have to say that for the workflow i prefer it over Aperure.
I have made the experiance that a picture with a lot of highlights looked unseable in Aperture , but was good once opend in Photoshop RAW converter. One step further: a picture shot outside, almost in the dark with only some light left from the lamps in the street, looked very bad in Aperture and Lightroom, once opend with Nikon Capture Editor it turned to be a great Picture in full scale size at 300dpi. I guess this is possible because they know exactly how the RAW is processed in the camera and their software is only dedicatet to Nikon. I think it should be the same for all other cameras.The only trouble is that Nikon Capture is very slow. But good work needs time:-)
So my conclusion is to use Aperture or Lightroom to organise and preselect the shoots, as well to make a webgallery for selection to the client.the selectet RAW picture i will then open in Nikon Capture and set the corrections. Then I open it in Photoshop to refine it and retouch. finaly save it as PSD or any other format desired.
There is one programm that I guess does the same high quality work on RAW files for all cameras and that ist Capture One Pro because of its dedicatet RAW conversion to each Camera type. I just dont lik the interface and its another 500 $ or so.
i hope this was ahelp to you.

ACR and Nikon D800e Raw files

This discussion is actually a follow on to an earlier one where I thought the issue was resolved. I am using CS5 extended 64 bit with WIN 7 64bit and ACR version 6.7. I verified the ACR version checking for updates and was informed I am up to date. According to the ADOBE help site ACR v 6.7 is available to open Nikon D800e raw files. However when I try and open these raw files there is a message that the camera model is not supported. Any help on why the raw files cannot be opened with ACR 6.7 is appreciated.

Thanks Noel - after several hours of experimenting, I found the issue. I use a stand a lone software, Nikon Transfer, to download images to the computer. The software allows me to preview/select, rename, and make simultaneous copies for backup. This software has worked without issue, however when downloading images from the Nikon D800e, it does something to the raw files making them incompatible with ADOBE's ACR and even Nikon's ViewNX 2 software. Now here is the real curosity. When Nikon Transfer is initiated from within Nikon View2 software and not as a stand a lone, it works, and ADOBE ACR 6.7 can read the raw files. Again thanks for the help.

Raw File conversion to Tiff or Jpeg - best workflow for multiple files in Photo Shop Elements 11

Hello, I am pretty new to shooting in raw and Photoshop Elements (11). I have one big problem. Once I open Elements up and load the Raw files from the SD card it shows them all on the left side in Camera Raw. I make my contrast and color adjustments if needed, but then my problem starts: I do not really want to make any further adjustments in Elements itself, but in order to save my Raw files either as Tiff or Jpeg it seems like I need to - through clicking on the "open image". Now it only opens up that one particular photo. I did not manage to go simply back to Camera Raw to grab the next one as the screen just disappears. However, this one by one process is of course not the preferred way. I know that there is batch processing, but am also not sure if my adjustments that I did in Camera Raw will carry over as I am actually never saving anything and would like to avoid saving it before all manually as .dng files as it would just be another extra step. I hope I could make clear where I have problems and what I would like to achieve and hope you can help me. Many thanks in advance.
Philip

Simply select and edit each picture thumbnail from the left panel without clicking 'Done' or 'Open'.
When you have edited each individual picture, select all your thumbnails - click on the first one - shift click on the last one. They should be all highlighted.
Then simply click 'Done'.
Your edits are saved in sidecar xmp files.
If the thumbnails are not yet automatically updated, select the files, right click and choose 'Update thumbnail'.
No need to use the editor with 'Open as' if you don't want any further edit or jpeg/tiff/psd/png version.
Edit:
I am not sure I have understood your question.
The above process lets you convert and edit a batch of raw files without opening the editor.
If you want to get jpeg or tiff files from the already edited raw files, either use the 'process multiple files' of the editor or the 'export' feature from the Organizer.
The common raw workflow in Elements consists in converting small batches as explained above to take advantage of applying common edits or individual differences. In some cases you want to open the editor, in others not.
That's at the input time.
When you want to output pictures, the selection of picture is different for each purpose. You'll include pictures edited in different batches, some still in raw format, others already converted in version sets to jpeg/tiff... For each output purpose, those selected pictures can be sent to the destination folder in the required format withoug opening the editor at that stage either using 'process multiple files' or 'export'.

Problems with RAW file conversion in PS5?

I recently updated Photoshop and Lightroom to PS5 and LR3. Never had any problems when I moved between the two programs before. Now, when I open a RAW photo (jpegs are fine) into PS5 there is a colour/contrast shift which gets saved when I import it back to LR (doesn't make a difference if it is LR2 or LR3). This happens even when I do nothing but open the file, do nothing and save it back to LR. I checked and the problem doesn't happen with LR4. I have ensured that my colour spaces and preferences settings are exactly the same in both PS4 and PS5. Please, can anyone help me? I have looked over the commentary on a lot of similar issues but haven't come across the answer. This is important because I am having problems when I send my photos out to a lab to print. Thanks in advance!

Dear Dorin,
Thank you, thank you, thank you for replying to my question!!!
I have been having a lot of problems printing (to a lab, not my own printer) since I upgraded to PS5 and LR3 so I am in the process of trying to eliminate all the variables.
The problem I notice is that my RAW files in LR3 (jpegs are fine) change when I work on them in PS5 and save back to LR3 or when I export them as jpegs to my desktop and re-import back to LR3. The photos become darker and slightly more contrasty. I have attached some screen shots. The differences are subtle when
looked at side by side but really quite noticeable when you switch back
and forth between the two. Different photos change more than others.
I have tried various other combinations and the photos stay the same (ie. photo from LR4 to PS5 and back, photo from LR2 to PS4 and back, photo from LR2 to PS5 and back). So I was thinking it was something to do with the way LR3 converts RAW files to other formats.
I use Spyder3 Pro for colour calibration and I have made sure that color spaces are the same across programs. I have also tried Adobe1998 and ProPhoto with the same results.
Thank you for your suggestion to figure out the ACR conversion. I couldn't find the option for plug-ins under "help" so perhaps I am doing something wrong. I think that my ACR is version 6.1.
Any suggestions you can offer would be greatly appreciated!! My business is getting quite backlogged while I try to figure this all out.
Thanks again for your help. Cheers, Michele

Sony RAW file conversion for Lightroom 5

I've been using Lightroom 5 (LR5) for my photo editing on a PC for a year now & been shooting with Nikon, just recently purchased a Sony A7II & LR5 will not read the RAW files, when I try it says: "The files are not recognized by the raw format in Lightroom 5", Please check for updated version of Lightroom, so I checked & I do have the current version, no updates available. I was previously told it would read it & there shouldn't be a problem, well it won't. From what I've read looks like I need to convert these RAW files to DNG through a plug-in. When I went to 'Adobe Support & Community Help' I found what I was looking (I think) a plug-in for LR5, however when you open the link at the top its says: 'Camera Raw plug-in for CS6, CC, or CC 2014 Adobe applications' doesn't mention anything about LR5, but it did on the previous search page so I'm a little confused. Attached is the link: Camera Raw plug-in installer
Is this it for LR5, 'CameraRaw_8_7_1.zip' ? And if so why doesn't it say for LR5, anyone know? I don't want to download something and have it screw up my LR5 program. Any help here would be greatly appreciated....jp

I have Lightroom 5.7. When I check for updates I show its up to date, I don't understand, whenever there are updates its always advised me, I started with Lightroom 5. Was that link to 5.7.1 on my post correct for this update? Like I said it didn't say for Lightroom 5 just Photo Shop CS6,CC, or CC 2014, so I was a bit confused, wouldn't be an issue if Lightroom 5 was included in the text.

Grey stripes after cropping and resizing any raw file

Dear Members,
this is an important issue which has forced me to suspend my regular workflow in Photoshop for now. I have updated my graphic drivers but nothing has changed so far (I currently have a Nvidia GTX 580, Intel i7 3770k, 32GB of RAM). I'll describe the issue using a sample raw image publicly released for testing purposes for the Nikon D3200 camera. I open the file in Bridge as usual and edit it with Camera Raw (I have version 8.7.1 now, I have the most updated version of PS as well). I'll low down the Exposure, the Blacks and increase the Contrast somewhat just to make the issue more visible. Then I import the file in Photoshop for other adjustments. First, I crop any area with the crop tool, and then resize it through Image -> Image Resize. Notice that the issue shows up only by resizing after cropping. I choose, say, a new width of 1024px, and then press Ok. Then an irregular pattern of both horizontal and verticle straight grey lines shows up:
My current Workflow Options in Camera Raw are set as follows:
Color Space: ProPhoto RGB
Depth: 16 Bits/Channel
Image Sizing, Output Sharpening and Photoshop boxes are unchecked.
This is from Edit->Color Settings in Photoshop:
I didn't try to test the issue by changing every single option in my workflow. I can only say that it just happens with any raw files under the settings I posted. JPGs work fine.
I would appreciate if you will solve what it is a very serious problem for my everyday work.
Best Regards.

Which version of Photoshop are you using? I tried to re-create this issue and could not:
If you are using lens corrections in ACR, turn them off. They are know to cause issues at times.
If still not working, try resetting the crop tool:
Now try resetting the image size tool. Press Alt and the "cancel" will turn into a "reset."
If still not working, try a preference reset: Ctrl+Alt+Shift as you initiate Photoshop's startup. It will ask if you would like to proceed, select "yes."
If still not working, I suggest you both submit a bug report here: https://www.adobe.com/cfusion/mmform/index.cfm?name=wishform&loc=en
Be sure to include as much information as you can.. System, Photoshop version, ACR version etc...
You could also try a re-install before submitting bug report.

Single Raw file conversion to .dng

Sorry if this has been asked but I can't find any tutorial on .cr2 file to .dng file conversion. I usually shoot RAW+jpeg on my Canon 50d. I am using CS3 and understand the need to convert my Canon Raw to the Adobe Dng format for PS processing. I downloaded and installed the free dng converter. I just can't seem to find a way to convert a SINGLE raw file into a SINGLE .dng file, it only wants a whole folder full for conversion. And am I correct in that Adobe isn't writing a plugin to let CS3 do the conversion? Thanks and Happy Thanksgiving!

You could copy the single CR2 file into a folder all by itself, then run the DNG converter on it. And I'm not completely sure, but I think I've heard of the ability for the tool to convert a lone file by providing the file path on a command line. Thus you could drag a single file to the DNG Converter icon if you had it on the desktop.
And you're correct - you're not going to get new camera support in the Camera Raw 4.x series that works with Photoshop CS3. Adobe stops adding new camera support when a new major version of Photoshop is released. But they do provide the (less convenient) DNG Converter for free.

ACR and Stitching From RAW Files

I see something peculiar happening on recent stitches.
I have say, three frames to stitch from RAW. One frames a little overexposed, so I open in ACR, drop the exposure to compensate and save. Then I open all three frames in Photoshop>Merge as RAW files. When the adjusted frame shows up, the adjustment is ignored.
I can fix this by opening the other two and do a very slight change to them, save, then all three show up as expected, the bright one matching the other two close enough to get a uniform stitch.
Now I am doing this as a quick test of the stitch, to see if I really am interested, and if so, I go back and open all three in ACR and make the corrections. After doing all three, I can uncouple the bright one and tweak its exposure, then save and stitch, no problem.
Is this normal?

I am selecting the images after making the raw adjustments in Bridge and selecting Photomerge under the Tools.
I haven't experienced this either until now. The difference is that Iwould always select the images and open in ACR first, and run the corrections synchronized. Occasionally, one would be off enough to require special tweaking so after the synch corrections, I would select it, correct it then click Done. Getting a bit lazy, especially with many panos waiting, I do a quick test and in this case, only one of the three needed tweaking. Running Merge as above ignored the tweak.
Try it yourself. Pick some images to merge that have not been through RAW, and tweak one only in ACR. Click Done then Photomerge from Bridge under Tools.
I've done this twice now, after exiting Bridge and Photoshop first.
Make that three times

CS2, Vista, and problems with raw files

Hello everyone. I have recently installed CS2 with RAW updates 3.6 on my new computer, which happens to have Vista on it. The RAW files I created with my Nikon D80 are not showing in Bridge either as thumbnails or when I click on them to enlarge them.
Does Adobe plan to address this problem through future downloads?
Any suggestions? I may be slow to respond since I will be out of town this weekend.
Thanks!

I've seen some strange things happen with Photoshop Elements on Vista. Some of it worked some didn't.
The security features of Vista are a bit too much at times and I got Elements to work by running the program with Administrator Priviledges.
It might be worth a try. Right click on the desktop icon and select Run as Administrator ( or something similar - I'm not on a Visa PC right now)

Photoshop Elements 9 and cannot open Raw files from my Canon EOS 1000D camera.

I am using Photoshop Elements 9 on a Windows 7 based PC and would like to know why I cannot open Raw files produced by my Canon EOS 1000D camera.
I have checked the version of the plug in as 6.5 for raw files which is supposed to open .cr2 files and should be compatible according to Adobe site info.
any ideas for next move.
Mick

Hi,
According to all of Adobe's charts, the Canon 1000D should be supported by the basic PSE 9 even without updates. When you said you checked the camera raw version in PSE, did you do that by going to the Help menu and selecting About plugins -> Camera raw?
The Canon 1200D requires ACR 8.4 which is only compatible with PSE 12 - so for PSE 10 your brother would need the DNG converter.
I can't find a sample raw file to try (I do have PSE 9). If you want to upload a sample file to dropbox and give me access, I could try it on my system.
Have you tried opening one of your files on your brothers system?

Creative Cloud is always empty and I cannot update LR and PS and cannot open RAW files from my new camera!

My Creative Cloud is always empty. I've had this trouble for over a year. I cannot update Lightroom because of it and Photoshop does not update properly. I cannot open the RAW files from my new camera, a Nikon D750. Each time I want to update, I have to talk to you and delete things and reinstall things but it doesn't fix it properly!
I have contacted Adobe before and always have to go through a tedious delete stuff and reinstall, then next time it happens all over again.
I'm really fed up with it and want to know how to fix it properly. I am in the UK, if that makes any difference.

Canon 5D mark II raw file conversion size blowout

I am suffering from an issue where my CR2 files from a 5D decrease in size when converted to DNG from for example 14.4MB to 11.8MB while the 5D mark II files increase from 8.7MB to a much larger 23.6MB after conversion. Both conversions are being done with DNG Converter 5.4 using the same preferences. Any light you could shine on this for me would be greatly appreciated.

It is because your 5D Mark II files are sRAW images, not raw. (The full 5D Mark II raw files are usually over 20 MB, not ~8 MB.) When you process sRAW files into DNG files, the DNG files are stored in the "linear DNG" format, which is much bigger than the sRAW format.
p.s., these questions should be directed to the Camera Raw, Lightroom, or DNG forums in the future to get a faster reply.

How do I get Photoshop CS3 and Bridge CS3 to show and open camerea RAW files?

I am not able to see or open Raw files from my Canon 40D in either Photoshop CS3 or Bridge CS3. At first I was able to open RAWS in Photoshop and then I followed directions on the internet at how to manually replace a Camera Raw Plugin so I could open it in Bridge and now neither of the apps work with RAW. In photoshop It says that the file is not supported.
I looked up what plug in I needed and it said 4.2 for a Canon 40 D. I also followed the instructions in the read me file that was with the plugin download. No results from it. I even tried to switch it back to the old plug in to see if I could atleast get back the capiblility of opening it in Photoshop even though bridge was not working...still can't open it in either. What am I missing?

You should install Camera Raw 4.6.
