Understanding Camera RAW with JPEGs

I usually work on the design end, hence I rarely work (professionally) with files straight-from-camera. I get the stuff after the photographers are done with it.
However, that is slightly changing and so I have a question about the Camera Raw plugin in Photoshop. In particular, processing JPEG images with it.
If I understand correctly, it does not actually modify the JPEG image itself, but merely saves the correction information as metadata in the JPEG file, which is then re-constructed when the JPEG is re-opened.
This would (assuming I understand it properly) make it a "safe" way of tweaking JPEGs as unlike most JPEG operations, no resave/quality-loss is occurring. Only the metadata is changing.
Am I correct or have I horribly misunderstood this process?

I can appreciate that - my own plug-ins all do their work in linear space as well for the advantages thereof.  However, it's not as if one can't get good results with the normal Photoshop tools, which for some reason seem to be out of favor...  One can convert to a linear profile to work on it in Photoshop proper, for example (though one has to craft or find a linear profile to use for that, as none is provided by Adobe).  I do my astroimage processing that way.
I might change my workflow to involve Camera Raw where JPEGs are concerned IF Camera Raw could be set to write its metadata back to a sidecar file or the central database instead of rewriting the JPEG file.  I understand that it is not rewriting the actual image data, but I just don't want it writing back to my JPEGs at all.

That button is not the Save As button, really, but a link to the DNG converter. To save your raw file in an image format, click the Open button instead and then save in the format of your choice in the editor.

  • Adobe Camera Raw (ACR), Jpeg Files and Metadata

    I have been using Adobe Camera Raw (ACR) with my Canon EOS 30D, an 8 MP camera, for a while now. I would make non-destructive changes to the raw file (.CR2) in ACR where the changes would be stored in an adjoining .xmp file. Jpegs of the unedited and edited camera raw files would be created so I have a before and after versions of the images that can be viewed anywhere.
    Now I have a Canon EOS 5D Mark III, a 22 MP camera and the raw files are much larger. I’m looking at using camera raw on jpeg files for some for my more casual photo shoots in order to save disk space. From what I have read, I can use ACR on jpeg files and that the changes would be stored in the metadata in the jpeg file. Is there a way for the changes to be stored in an adjoining .xmp file so that the original jpeg file is not modified, much like it is done with the .CR2 files?
    I am using Adobe Photoshop CS5 on a Windows 7 machine. All software is up-to-date.
    Also, I have found that Adobe’s camera raw handing is different than the raw handling of the photos using Canon’s software (DPP). Is there a way to make ACR closer to what Canon’s software does?
    Thanks,
    Mike

    Probably not going to happen.
    I agree, Canon's color is better than Adobe's in general - I just didn't know how good the Camera Standard profile might be for your particular camera.  I had hoped maybe they'd made it a very close match.
    Some time ago I got a very nice genius-level Camera Raw forum member named Vit to make me a custom profile that exactly matches the Canon color for my 40D, even to the point of emulating the way Canon fits the entire gamut of the captured image into the sRGB color space, so I'm more than happy.
    Others might tell you that you're silly for wanting the color to match, but I understand completely your position - if you do get that kind of feedback just ignore it and push on.
    Once you've set up a default to use Camera Standard, you may well be able to tweak the dozens of color controls to bring the Adobe default into line with the Canon color.  I did that once before getting my special 40D profile, comparing embedded raw file JPEGs with the Camera Raw preview display with a variety of images - it was tedious but effective.
    Best of luck.

  • Camera RAW ruining JPEGS, cant disable

    I have CS3.
    Certain jpeg files now ONLY open with Camera Raw in PS, no matter what I do. I just want to open them regularly, but I cant get ACR to go away, and ACR is corrupting the color somehow when it opens them this way.
    Under preferences, (in both PS and Bridge) I have disabled 'prefer camera raw' for jpeg, but that still doesnt help.
    The problem is the color gets ruined when opening them with ACR, no matter what color space I choose from within ACR when developing them, the files get a washed out appearance, and once opened this way, cant be fixed via normal methods, ala 'converting to' or 'assigning' the right color profile.
    Note that other jpegs not opened with ACR before seem fine and unaffected, they do not open via ACR in PS, they just open normally in PS, and I see the expected 'color profile mismatch' if relevant.
    Also note that the files that are getting ruined by ACR look OK in Bridge and from within the ACR preview window itself, but once opening into PS, they look totally different.
    Can someone please tell me how I can stop ACR from ruining them or just disabling ACR for good? Thanks. The files are essentially unopenable as they are right now, and I dont see any 'clear' develop settings options as later versions of PS seem to have.
    Thanks!

    Thank you!!!
    From your screenshot I realized I did not have those options available, so I upgraded from camera raw 4.0 to 4.1, and sure enough, they included those options in the update.
    Once I unchecked them, the notorious ACR did not open!
    I still wonder why the color gets corrupted by ACR, but am not the biggest fan of ACR anyway, so will not use, long live Lightroom, LOL.
    Do you know, is there a 'limit' to the level of ACR I can upgrade to from within CS3?
    Anyway, Thanks again for saving me,

    Photoshop CS6 - How to export form Camera Raw to Jpeg of 300dpi?

    What does your package include besides this disc?
    If your artistry and production are at a high-level and you are charging tens of thousands of dollars then protecting your reputation and future-sales possibilities by not giving them a disc might be wise, but if you just want to be done with things after you get paid, then a disc or flash-drive of native-resolution (not resized) and uncropped JPGs might give the most freedom for the client, although if I was your client, I’d want the RAWs or at least DNGs with your settings saved to them.  If there is enough space on the media then you could put a folder of JPGs and a folder of TIFs, separately.  It depends on how many you’re giving them.  If you’re high-end you could give them an Wi-Fi iPad with the photos on it, or at least a non-Apple tablet with a removable flash-card for more easy offloading.

    You need to buy PSE13. But you can continue with PSE9 if you download and install the free DNG converter to convert your CR2 files to the Adobe universal Raw format and the DNG files will work with yoir existing software(keep your originals as backups and for use in the camera manufactures software)
    Windows download (.exe file) click here DNG Converter 8.8
    Mac download (.dmg file) click here DNG Converter 8.8
    You can convert a whole folder of raw images in one click. See this quick video tutorial:

    Using the Open button in ACR to get to PS doesn’t create a PSD or a TIF, it just transfers the image in memory.

    there are several ways to do so.
    1)You can find a save image button at the bottom left corner of the camera raw dialog box.
    2a)You can click the open image or open object button lower right hand corner of camera raw dialog box (hold shift key to switch between the two buttons) Then use file>save as... then choose jpg from the format drop down button.
    2b)or once the image is loaded into photoshop you can use file>save for web and devices... then change the preset or the format drop down menu to jpg.
    3) For a more automated approach, you can also use either file>automate>batch or file>scripts>image processor to convert a folder of images to jpg. Conversion is a copy process, it does not overwrite the files. Going this route, is suppose to bypass camera raw dialog box all together and save the new files in a new folder. This is also how to apply an action to the files during the process. It is wise to practice this on a few copied images first to see how it works, just so there are no surprises.
    4)you can also use Bridge and create a web page of jpg images.
    These directions may differ depending on your version of photoshop and operating system of your computer.

  • Use Camera RAW with Sony Nex-3

    Hey Guys!
    I want to get out more details from my photos.
    Im using Adobe Photoshop CS5
    Sony NEX-3 Compact Camera (listed in the camera raw compatibility list)
    First i changed the cameras picture format from jpg to RAW & made some photos.
    At home i tried to open the files with Camera Raw. Doesnt work. The sony camera saved the pictures as an ARW File.
    So i downloaded Adobe DNG Converter. I converted the ARW into a RAW file and opened it with camera raw.
    So far so good! I opended the RAW picture with Photoshop. Just for testing with 8 & also 16 bit. Does my camera support 16bit?
    I compared the RAW File with the new created jpg.
    Normaly the quality of the raw file should be much better than the compressed jpg i think.
    I took a look at some other jpg pictures (i shot them in JPG Mode) & compared them with the RAW Images (RAW Mode).
    I saw absolutely no difference between RAW & JPG.
    I also tried a exact tonal value correction at both images.
    Same with other picture corrections. Details, Noise, Sharpness.... same.
    With the Sony NEX-3 there also was a RAW Program included which opens the ARW Files.
    I cant see some differences between RAW & jpg here too.
    What I am doing wrong?
    I have to say that i am an camera raw beginner. I tried this for the first time. I thought this would be easier!
    At the screenshot below you see a JPG picture on the left & a 16bit DNG on the right.
    I found no differences!
    I would be very happy about your help and some good advices.
    Best regards Andi

    Basicly i understand how RAW works. But im still wondering why i cant see just only a very little difference to my jpg Images.
    The image of the Mountain Railway Station i postet has a lot of dark shadow areas & details.
    I´m also wondering why these chromatic aberrations are shown in the RAW file? I thought its only in the jpg images because of the compression.
    Your raw file may be 12 or 14 bit, and have no output colour space - it is only limited by its physical characteristics and analogue-to-digital converters. You should set Camera Raw for the biggest workspace necessary, which in my case is 16 bit AdobeRGB. Others work in ProPhotoRGB—it's a personal choice. This has the effect of constraining the raw data, and you will learn to use the sliders to work within those constraints.
    Using normal processing settings there will only be subtle differences between the conversion preview and the camera JPEG. The tonal response will be slightly different, seeming slightly lighter or darker, and the colours' hue/saturation will be slightly different too. Also, depending on the camera, automatic distortion/vignette/aberration correction will be missing. This is all to be expected, and your expectations have been misplaced.
    However, this is only a starting point. Whilst JPEG shooters can go on to process their images, the resulting quality will be inferior; JPEG is a finished image format. Raw shooters have much more to play with, and can manipulate the conversion's parameters to boost shadows, recover highlights, adjust mean exposure, increase/reduce/localise sharpening and noise control, apply processing gradients and masks, apply local contrast and selective saturation boosts, and correct your camera's colour response, as well as apply lens defect corrections—all before the conversion to JPEG.
    So, you won't start to see the difference until you start to push these adjustments. You have been given a second (and a third and a fourth...) chance to create your JPEG using your own set of picture parameters, and the ability to change these parameters for each photo after taking the photo.
    In your photo above, you can bring out detail in the shadows by boosting Fill and Blacks. As you shot in Raw, you will have a good amount of tonal resolution recorded in the shadows (assuming you didn't underexpose in the first place), which would be absent from a JPEG. You also have the ability to change the sharpening to suit the image, and even apply local sharpening where it's needed most (and less where it's not needed).
    You also have the ability to modify Camera Raw's default settings how you like it. You can enable automatic lens defect corrections (like chromatic aberration—make sure you're on ACR 6.7). You can change the default camera profile (which dictates how tone, hue and saturation is translated) to a preset, or make your own using a calibrator. Do this and your starting point will be how you want it, not how Sony wants it.
    I could go on, but I think you have probably heard much of this before. The main point I'm making is that you shouldn't expect to see a big difference straight away, but the possibilities you have created are much greater.

  • Unable to upgrade Camera Raw with CS4 in Lion...

    Hi All,
    very frustrating; I have been unable to upgrade Camera Raw despite several attempts.
    I've downloaded the latest version as an upgrade; I've done Software upgrades through PhotoShop, but for some
    reason these do not seem to have taken, ie., the version of ACR in Bridge preferences remains 5.0.
    This makes it impossible for the computer (a brand new MacBook Pro) to read or convert to DNG raw files
    from a Nikon D300S.
    Oddly, ACR 5.0 converts raw files from a D700 just fine.
    Also puzzling is that my attempt to upgrade to ACR 5.7 in a 5 month old iMac have been smooth as silk (OS 10.6.7)
    Help!
    Stu Rosner

    At one point, I was one of the most vocal critics of camera raw in the CS4 / Lightroom v2 days. In short, I felt that there was not enough control over noise reduction and fine detail rendition when processing digital camera raw files, especially at higher ISOs, although I had been quite pleased with earlier versions. That all changed when CS5 / LR v3 was released. You now have an enormous amount of control over exactly how much sharpening and how much noise reduction will be applied to an image. The amount of fine detail one can extract from a low-ISO raw file is extraordinary. When you crank up the ISO and an image gets noisy, you now can choose whether or not you prefer a smoother look at the expense of some of the more subtle texture details, or a slightly grainier look where one has a feeling that no significant fine details are lost from the original capture (what I prefer). The raw processing defaults in Adobe's latest software are good starting points, but for my personal tastes, I generally do modify them a bit with less NR and slightly more sharpening at a smaller radius.
    Even out-of-camera JPEG files will benefit from the new processing engine. I find that turning down the sharpening and NR in-camera, and then applying some subtle tweaking in LR, for example, makes for much better looking images even when starting from a JPEG. If you are a raw shooter, like I am, then upgrading to the latest Photoshop and Lightroom is absolutely 100% worthwhile in my opinion!
    I personally feel that the quality of raw conversions in Adobe's latest software are pretty much the best there are. I have used many other raw converters (Capture One, Aperture, RAW Developer, Silky Pix, Canon's DPP etc.), and while each have their strengths, overall I far prefer the look of the final image from Adobe's latest software. Sure, I might find the colour rendition slightly better, in some cases, from some other raw converters, but colour I can fix. Poor detail rendition or heavy-handed/crude noise reduction I cannot.
    EDIT: Also should mention how good the lens correction controls are. Not only are there automatic lens corrections available (possibly of limited use with an M8 due to potential lack of lens EXIF information), but the manual corrections are extremely useful. Chromatic aberration, vignetting, highlight fringing and distortion control all work extremely well and are minimally harmful to image quality, unlike performing those same corrections in Photoshop after the raw conversion stage. You also have excellent perspective corrections that, amazingly enough, seem to have very little impact on image quality even when fairly dramatic adjustments are made.
    Lastly, I own both Noise Ninja and Topaz DeNoise and since upgrading to Adobe's latest software, I don't think I have felt the need to use either of those two third party NR plugins once. Purely from a noise reduction standpoint, upgrading to CS5 or LR v3 is almost like getting a new camera, almost like moving from a cropped sensor to a full-frame as far as high-ISO image quality.
    I would suggest you download Lightroom v3 and give the 30 trial version a whirl. Spend some time in the Detail section of the Develop module and make sure that for each image you are looking at, ones that you may have edited in previous versions of Camera Raw or Lightroom, that you have "2010(Current)" chosen in the "Process:" section of the CameraCalibration tab in Develop. That will ensure that you are fully benefitting from the latest raw conversion engine. Zoom in to 100% before you tweak the Detail settings to make sure you are seeing actual pixel-level detail. I think you may be amazed at what you can do...

  • Camera Raw with PSE 13

    Is Camera Raw supplied with PSE 13  much improved than that with PSE 9

    LR4 introduced PV2012 and the corresponding version of PS's ACR would be 7.x, but ACR 6.7 was released with the ability to understand LR 4 settings, since LR was released before PS that year, but it didn't have the full UI to adjust everything.  I think there was a way to switch to PV2012 in ACR 6.7 just to get to the older and newer settings if both were in the XMP metadata but I don't think all the toning sliders were there until ACR 7.1, just the common ones like Clarity that switched back and forth between the two PV methods.  I remember some problem that ACR 6.7.x fixed but there was never a LR 3.7 released to fix it since LR 4 was already out.  Of course I may be remembering some of this wrong, too.
    Look at the first comment and reply:
    http://blogs.adobe.com/jnack/2012/03/camera-raw-6-7-available-on-adobe-labs.html
    Here are the ACR 6.7 release notes that talk about things looking different between LR 4 and ACR 6.7 (RC?) as well as a problem with Clarity so maybe I've comflating the two in my mind:
    Adobe Camera Raw 6.7 and DNG Convertor 6.7 Now Available on Adobe.com
    Of course this has nothing to do with PSE9 since its last ACR was 6.5, the year before PV2012 was available.

  • How can I use the color adjustments interface that shows up for camera RAW on jpeg files?

    How can I use the color adjustments interface that shows up for camera raw on other files types? The HLS controls had the secondary color adjustments (6 colors instead of the 3). Plus, it had same vibrancy and a better Curves interface. Yesterday was the first time I imported raw into Photoshop CS5 and I got that really cool interface. What is that? Can I use that on other file formats?

  • Camera Raw with Elements 7 and Windows 7 ?

    I just got a new computer (i7-2600 quad core processor, running Windows 7) and installed Photoshop Elements 7.0 (and Premiere Elements 7.0) from thew original installation disks. Everything seems to work so far, but I want to be able to use my Canon's (EOS T1i) RAW format (extension .CR2) as I did with my old computer (running Windows XP). I followed the on-line instructions and downloaded the Camera RAW 5.6 plug-in (stated to be the last version which works with PE 7.0). I then ran the CameraProfiles application. I then tried to navigate to the Program Files/Adobe/Photoshop Elements 7.0/Plug-Ins/File Formats folder to find the Camera Raw.8bi file. However that path does not exist. I did find the Camera Raw.8bi file in Program Files (x86)/Adobe/Photoshop Elements 7.0/Plug-Ins/File Formats (not surprisingly). But then the instructions say to copy the plug-in to the original folder in mycase, Program Files (x86)/Adobe/Photoshop Elements 7.0/Plug-Ins/File Formats) and launch PE. After doing so, I still can't open the RAW files. (I even tried creating a new path in the original Program Files folder, but that didn't work either.) What am I doing wrong? What do I need to do to access the .CR2 files in PE 7.0?

      Can you check that Camera Raw 5.6 installed correctly.
    Open the Editor and on the top menu click:

    You should see something like the following confirmation. Make sure it is version 5.4 or higher. Press Esc to close
