Generating "raw" images in ACR?

I'm working with "raw" images using custom software, and I'd like to be able to pass images processed in ACR into my software.
I can currently pass dng images and proprietary raw images (such as direct from cameras) into my software. I want to process a raw (from camera, e.g. NEF) image in ACR and then save that processed image as dng, for passing into my software. However, when I examine the (processed) ACR-saved dng, I find that the raw pixel data in the dng is *not* modified. I suspect that the modifications made in ACR are stored in the metadata of the dng when it is saved in ACR, and are only 'applied' to the raw pixel values when interpreted by appropriate software. Is this correct? And if so, is there *any* way of producing an ACR processed dng file in which the raw pixel data *is* modified? i.e. so that the results of the processing can be seen when the dng is viewed in RawShooter for example? The processing I am doing in ACR is lens distortion correction.

Yes.

Since the answer two the first question is Yes, that naturally implies a No for the second. You can save a demosaiced DNG, which is essentially a TIFF. That's what DxO used to do (and still does) when passing lens-corrected RAWs to other converters.

Reverting to original RAW image in ACR

In the past I have almost always used Nikon's Capture NX2 as my RAW editor. In that, it's immediately obvious how to get back to the original NEF camera image, or even choose to go back to different stages in the editing history.
There seems no obvious way to do this in ACR. For example I made a mistake in a RAW edit, but when I reopened the RAW image again from Bridge I got the edited version with the unwanted error.
I would appreciate some guidance on this. In an ideal world, I would like ACR to do what Nikon Capture can do.
I have also just found that, when trying to assign a keyword to this file in Bridge, I got got an "...error writing metadata" message. All the other NEF files in that folder (none of which have yet been edited in ACR) accepted the keywords with no problems.
Since writing the above, I have found that this "error writing metadata" is a common issue for which there seems no solution - it extends back to earlier versions of Bridge (I have CS6 64-bit with vety latest updates).
I have deleted the sidecar file for the file in question, but the error remains.
I cannot help being a little concerned about what ACR actually does to the file. Maybe I'll go back to Capture NX2 (not without its own problems) unless there are some solutions to these issues.

There are several ways to go back/edit history.
In Bridge, select the photo you edited in ACR. You can see the Edited symbol above the photo upper right.
Go to Edit menu, Develop Settings, Clear Settings.
In ACR you can also make Snapshots of different times in your editing session.
Go the Snapshot tab (the rightmost tab) in ACR. Click the New Snapshot icon in the bottom right and name the snapshop. You then can go back to a previous edit by simply clicking its tab. The caveat is that you need to manually add these Snapshots as you go along.
You can also go back to an earlier edit and Open the Image in Photoshop while still retaining the later edit shapshots in ACR
Lighroom has a real time history that you can go back to a previous edit. This history is automatic. I'm not sure if the history is retained after the file is closed and then reopened. I tend to think not, but you can also create Snapshots in Lightroom.

How to undo cropped and rotated RAW images in ACR

Can someone advise on returning to the original RAW image after the image has been edited in ACR.
"Reset Camera Raw Defaults" seems to do everything but undo crops and image rotation.
How do I undo these and/or return to the original unedited image?
Many thanks

Thanks but how exactly do I find the unedited CR2 within PSE/ACR?
Everytime I open the file in PSE or ACR the edited version comes up and the most original version I can return to is to reset the Defaults. However, this does not reverse crops and rotations
I have noticed that the original CR2 file is viewable within MS Explorer but I'm reluctant to delete the .xmp as I don't want to loose keywords etc associated with the image.
Many thanks for any suggestions

Adobe XMP Files not deleted with Raw Files in ACR

I am using Photoshop CS3 on a Windows XP platform. My camera raw files are mostly kept on a Windows 2003 file server, which has a gigabit connection to my workstation. However, I have the same problems when using PS CS3 on my Windows XP laptop.
I take many hundreds of 'technical' photographs using an Olympus E1 and Canon G9 cameras. I usually bracket the exposures on the E1, specially when photographing white painted yachts, and then rate and select the images that I want in ACR 4.1.1. Unwanted images are deleted at this time.
The problem I am having is that the associated *.xmp files are not always deleted with the camera raw files, with the result that I now have literally thousands of these 'orphaned' files cluttering up the server. The only options I have are to delete the files manually, which is a pain, or to leave them on the server, wasting unnecessary space.
I have the same issue with Canon and Nikon raw files, so this problem is not specific to Olympus files.
This is a long standing problem, and I would be grateful if anyone has any answers?
If any Adobe programmers are watching, it would be handy if you could provide a simple utility to delete orphaned *.xmp files, or at least compress them into some kind of archive.
Thanks,
Nigel.

[quote] As far as Photoshop and ACR go, ALL raw files are treated as read-only.
Your original raw files remain untouched, no matter what you do to them.
Any adjustments you make to a raw file are kept only as metadata (flags, if you will) in that XMP side-car file. Every time you want to re-open that raw image file, ACR will reach for the XMP file and apply the adjustments automatically, transparently. [/quote]
That is not quite correct. Camera RAW files can be permanently deleted from within Adobe Camera Raw. The problem with ACR 4.1 to 4.4 4 was that the XMP files were left behind. This now seems to have been rectified in the latest version (ACR 4.5).
Thank you Adobe!

Images in ACR are softer than when viewed in Photoshop?

Greetings,
I'm finding that when I view a RAW image in ACR 4.1 that the image does not appear as sharp as when I open the image from ACR into Photoshop and view it in Photoshop. I open my RAW files from ACR into Photoshop as PSD files. The image as viewed in Photoshop looks sharper at values less than 100%. Here's a screen grab of the same image (Photoshop on the left, ACR on the right), side by side at the exact same viewing size (23.1%), and the Photoshop image has more sharpness and clarity to it. It's minor, but noticeable in the leaves and bricks and it gives the ACR image an overall soft feeling.
http://www.pixentral.com/show.php?picture=1jidvrPRXgXSfq8c5IHonNL13oeEI
Do the programs handle interpolation diferrently when viewing images at less than 100%? Or, do RAW and PS files inherently display differently when not viewed at 100%? When both are viewed at 100%, they match. This isn't a major deal breaker -- but the lack of clarity at smaller viewing sizes in ACR is unfortunate, since I rarely view images in ACR at 100% size when I'm reviewing images and images that I think are soft are, in fact, not.
The disparity seems more pronounced with images in portrait orientation.
I'm using a Mac Pro, Radeon X1900, 23" ACD. Canon 5d images.
Anyone experience similar? I love ACR, but wondering if someone can shed some light on this.

Thanks for the clarification now -- it makes sense. I knew ACR only showed the effects of sharpening at 100%, but had forgotten to take into account Photoshop shows the effects of sharpening at all sizes, including under 100%

Does CS6 raw image converter also support PowerShot G1X MKII raw images?

I recently bought an PowerShot G1X MKII and always work with raw images. I have CS5 which does not support those raw images. Before upgrading to CS6 I wonder if anybody has experience with opening PowerShot G1X MKII raw images using ACR in CS6.

I just checked the supported camera list published by Adobe. It indicates that there is preliminary support for that camera in the latest version of Camera Raw. That version will not be compatible with Photoshop CS5. But you could download the DNG converter version 8.4 and convert those raw files to the DNG format and use them with what you already have. You could purchase Photoshop CS6 and install Camera Raw 8.4 and have support for your camera, albeit preliminary support. But new features that have been added to Camera Raw since the introduction of Photoshop CC will not be available to you. But since you don't have those features now that probably wouldn't matter. You could also add Lightroom to your workflow, turning to Photoshop CS5 when needed. Here is a link to the Adobe webpage that lists camera support:

HELP. ............Hi folks hope some one can help me please.Having a problem in Bridge I open my images in ACR, as I open files in a folder and lets say they are labeled in yellow they are all going back to the camera raw default , in other words no matter what work I have done, inc cropping they all go back to ,as they came out of camera.

I recently changed computer to 64bit from 32bit, not sure if this causing the problem or not. Any help would be appreciated.

Robert,
Would you be so kind to rephrase your question with concise, precise information and without any "let's say that" hypotheticals? Sorry, I can't quite follow you.
Also please give exact versions of Photoshop CS6 (13.what.what), of Bridge and of your OS.
Thanks.
BOILERPLATE TEXT:
If you give complete and detailed information about your setup and the issue at hand, such as your platform (Mac or Win), exact versions of your OS, of Photoshop and of Bridge, machine specs, what troubleshooting steps you have taken so far, what error message(s) you receive, if having issues opening raw files also the exact camera make and model that generated them, etc., someone may be able to help you.

Lightroom doesn't recognize ACR 5.5 and my D300s RAW images

Lightroom 2.4 does not recognize my Nikon D300s RAW images. I downloaded ACR 5.5 and after install both Bridge and Photoshop CS4 handle the D300s RAW images but my Lightroom 2.4 will not import them saying that it is a damaged or unrecognized file type. I have rebooted my entire Vista system and the problem persists. Any suggestions on how I might make Lightroom recognize ACR 5.5 and my D300s RAW images? Thanks in advance.

You don't want Camera Raw 5.5 (unless you want to use Photoshop CS4), you want the DNG Converter 5.5 which can convert the D300 raws into DNGs that are compatible with Lightroom 2.4. The next version of Lightroom (presumable 2.5) will have the support built in without needing the DNG Conversion...

PSE7/ACR 5.6 issue with Canon 7D raw images too dark - solution?

Whenever shooting both jpeg and raw images with my Canon 7D and uploading to PSE7 (where I use ACR 5.6 to convert raw) the raw thumbnails are a stop darker than the jpegs. When converting a raw 7D image, the exposure needs to be increased by a stop (this needs to be done whether or not jpegs are also shot). This phenomena does not occur with my Canon 50D using the same raw converter - the jpeg and raw image display the same exposure and raw images do not need the exposure increased.
I have noticed in the raw converter on the Camera Calibration tab that - for the 50D - the Camera Profile contains ACR 4.6, Adobe Standard, and the Canon camera profiles, whereas for the 7D the Camera Profile only has the Adobe Standard and the camera profiles. The converter does say 7D at the top of the screen, however, so the converter recognizes the 7D. Is there a 7D Camera Profile that needs to somehow be configured/uploaded, etc.? ( I did run CameraProfiles.exe)
The 50D and 7D are set up the same, so this is not an ALO or some other camera setup issue - I have done extensive testing in this area. Also, Canon DPP displays the thumbnails (raw & jpeg) and the raw conversion exposure correctly, which tells me that this issue has something to do with ACR 5.6.
Is this a setup issue in 5.6? Or, do I need to upgrade to PSE8 and ACR 5.7 or 6.1 to get around this?
Thanks for your assistance.
Ed

Update:
I installed PSE9, which comes with ACR 6.1, and the issue was not resolved. So, I downloaded ACR 6.2 - same problem: EOS 7D raw images (thumbnails and when opened in raw converter) are 1 stop under-exposed. As stated above, Canon's DPP doesn't exhibit this problem, nor does FastStone Image Viewer, only ACR. Anyone else having this issue? Thanks for any help.

Problems reverting to original RAW image (ACR 7.3)

My understanding of using Camera RAW is that you never lose the original RAW image as shot by the camera.
I've found out the hard way that this does not seem to be true. I opened a Panasonic RW2 file in ACR 7.3 and, among other adjustments, cropped it.
Now even when I select Camera Raw Defaults from the flyout in ACR I cannot get back to the original uncropped image.
Have I lost that original for good - I thought this was not supposed to happen?
John

In ACR simply reset the crop by choosing Clear Crop in the cropp tool dropdpwn menu...
If you want to clear ALL settings AND crop, in Bridge you can go to Edit menu, Develop Settings and use the command Clear Settings...that's the quick and easy way of resetting an image.

Updated acr to 6.2.0.29, but LX5 raw images do not open

Hi,
I just purchased two cameras, the Panasonic dmc-fz100, and the dmc-lx5. I have no problem with the fz100, and can open the raw images in adobe photoshop cs5,(acr v 6.2.0.29), and can also convert these files to dng, using the dng converter v6.2.0.28. Unfortunately, I cannot open the raw files of the dmc-lx5. My operating system is OSX 10.6.4. Anybody run into this problem? Any suggestions?
thanks for any help,
Robert

Hi,
I can confirm that also using Windows Vista as operating systems the dng converter v6.2.0.28 doesn´t work with the Panasonic dmc-lx5 (program finds no files to process). I tried also Lightroom 3.2 which should be able to process the dmc-lx5 raw files according Adobe but here the same problem: Only a wildcard with the message "preview for this picture is not available" is shown instead of a preview.
Any workaround available?
thanks,
Ralf

LR 5.6 doesn't support the new Nikon D750. You have to wait to the next update.
You con also install the release candidate of the DNG converter and convert your NEF files to dng.

D700 RAW Images Overexposed by ACR

Is anyone else having problems with d700 RAW images being significantly overexposed during the conversion process in Lightroom? The preview of the images are spot-on, beautiful and perfectly exposed (I know this is the JPEG data) and then it's as if some gremlin wreaks havoc - the histogram disappears and when it comes back, voilà! A harsh, overexposed image is what is left. I typically have to manually "underexpose" each image in the develop module between 2/3 and 1.5 stops - sometimes 2 - to get the exposure into the same neighborhood as the preview and then have to perform a boatload of other adjustments to correct for the flat, cold tones. It's adding so much time to my workflow, I'm afraid I may have to switch over to Capture NX2 - it seems to nail the RAW conversion perfectly - which would be a huge pain in the rear. Any help or direction would be appreciated - this is really a frustrating issue. There is a fair amount of discussion about this in the Aperture forums (Aperture's RAW conversion engine also seems to be blowing out D700 images) but I can't find anything on-point here about LightRoom.
Am using a Macbook Pro with OSX 10.5
Thanks // Bill

There are three causes for this and No it should not happen. Go to one of your images and hit "reset". The image should return to being correctly exposed and fairly close (but not exactly the same) to the in-camera jpeg.
1. As Dennis says, it is possible you are applying auto adjustments. Uncheck the preferences for that. While you are in that screen make sure you also reset all camera defaults.
2. You are applying a preset on import. Make sure there is nothing like that in the import pane. Also make sure to hit reset on any images that were impacted.
3. Camera RAW (the processor under the hood in Lightroom) is not the same RAW processor as your camera and Capture NX. They will render RAW differently. Read this
FAQ entry for an explanation. You can make Lightroom render the same colors as your camera by using the
Adobe Camera matching profiles. They really work as
I showed here a long time ago.
There is no good reason to go to Capture NX except when you need a lot of the U-points stuff. You can get Lightroom to render identical to jpegs out-of-the-camera and it is far faster and more convenient than the horrifyingly ugly(in my opinion) NX.

How do I open RAW images in Photoshop?

I just purchased a Canon G9 camera with RAW image capability. When I try to open a RAW file in Photoshop (version 8.0) I get an error message: "Could not complete your request because it is not the right kind of document"
Any help will be greatly apprectiated!

Well, you have the old Photoshop CS (8.0), which supports only ACR 2.4. (ACR = Adobe Camera Raw.)
Your camera generates raw files that require ACR 4.3 to open directly in Photoshop. Therefore, you will never be ablo to open the raw files from that camera directly in Photoshop CS (8.0).
You have two choices:
• You can download the free, stand-alone DNG Converter 5.3 and run it to convert your raw files to raw DNG files first, which you can then open in ACR 2.4 hosted by Photoshop CS.
• You can upgrade to CS4 and open your files directly in ACR 5.3 hosted by Photoshop CS4.
