Add option for lossless uncompressed RAW files for A7r

I'd like to see the option for lossless, uncompressed RAW files for those of us who want it vs. the current situation of only having the option of lossy compressed RAW files (which in some instances, can exhibit posterization). I think this is a logical option for a camera of the A7r's calibre. If this option can be incorporated via firmware update, all the better. If it's a hardware issue, hopefully this is addressed in the next iteration of the camera.

Honestly, this is pretty deceitful marketting on both the Sony A7 and A7R literature. both promote the use of 14 bit RAW encoding as a feature of the two sony cameras, however, they are really 11 bit + 7 bit compressed lossly RAW formats, delivering no where close to the same tonality of 14 bit true RAW. in no sony literature that i could find, is it mentioned that it's lossly. this is accurate?  Not even close.  14-bit RAW output for rich tonal gradation 14-bit RAW image data of extremely high quality is outputted by the a7. This data fully preserves the rich detail generated by the image sensor during the 14-bit A/D conversion process. When developed with Sony's Image Data Converter RAW development software, these images deliver the superb photographic expression and rich gradation that only 14-bit data can offer.  I was going to purchase two A7R bodies and move my canon gear over to Sony ..until really all this came out.  I'm hoping as well as the OP that a firmware upgrade comes out.

  • Trouble with iPhoto after latest update for compatibility with RAW-files

    Hi all, I'm having serious trouble with iPhoto since the latest update for compatibility with RAW-files for digital fotocamera's (version 2.4).
    After connection with the camera iphoto starts up as usual and i can start importing my pictures. So far all goes well. After having imported my pictures (visual with thumbs and so one) and having created an event iPhoto isn't able to show any pictures. Stopping and restarting Iphoto gives a message that there are a number of photo's available that havent been imported yet (!!???). I can choose to import or ignore. Whatever i choose i'm not capable of visualising the photo's.
    Anyone with a similar problem and the solution? Can i remove the update?
    I've tried several camera's all with the same problem.
    thx for any replies
    niki001

    Hi Terence, thanks for the reply (i'll wait with the downgrade for now ;-p).
    I made a small step by step report of my findings:
    1. Attach camera to imac
    2. iPhoto starts up with previews of the pictures (so far so good)
    3. Give event-name and start import ( so far so good)
    4. 'Latest Import'-report all fine, previews ok, check with event : previews fine. All seems well
    5. disconnect camera, stop iPhoto. As far as now all seems normal.
    6. Restart iPhoto : Message 'iPhoto Library contains photo's which havent been imported. Import Y/N?'.!!!???
    7. Option Y : IPhoto imports photo's imported in step 3 in a new event box (shown as a 'black box' on screen). Last made event (step 3) shows up as a black square in overview all events. Double click on event gives empty squares where previews should appear. Double click on photo preview gives large explanationmark on screen.
    8. Drag event-box over screen shows thumbs within square, release event returns to 'black box'.
    9. Shut down iPhoto.
    10. Restart iPhoto jumps back to step 6 as long as i keep answering Y.(Each time creating a new extra 'black box event').
    11. When i now look within iPhoto Library i can find a map Import in which i can find back the last imported photo's from step 3.
    12. Dragging these pictures to my desktop (preview gives no problem at all) and from there back in to iPhoto simply recreats a new 'black box event'.
    13. In step 6 option N gives a message 'creat iphoto Library recovered'. In iPhoto Library map Import has disapeared.
    14.When looking into map 'iphoto Library recovered' i can find my originally iported photo's. However same problem as in step 12.
    I used aperture (trial version) to see wether the problem could be photo-related, but here al goes well.
    So, any idea's???
    thx

  • Option to always use sidecar files for XMP

    Lightroom gives you the option to write metadata to XMP files, which is convenient if you want to share data with other programs (ACR, various DAM programs). In the beta versions, this data would always be stored in .XMP sidecar files, presumably for safety reasons. However, V1 writes the XMP data into the image file itself for those formats that support it (DNG, JPG, TIFF).
    I would really like to have the option to *force* Lightroom to use sidecar files for XMP data, like the betas did. The current V1 behavior (embedding data) is quite inefficient for fairly common backup scenarios.
    For example, I tend to back up all my raw files onto DVD after importing and culling. In addition I make a daily backup of all metadata that gets sent over the internet to a web server - a relatively small upload. What happens if I use DNG for my raw files and update something as small as a keyword? Indeed, *all* of the corresponding DNG files are modified, and because my backup software cannot know that only the XMP data has changed, all files must be burned to DVD again. If the metadata were stored in sidecar files, a simple, efficient metadata backup would take care of things.
    To implement this, a simple switch in the preferences would suffice, and the necessary code is already there. The only possible problem is the occurrence of two files with identical names, excluding the extension. For this case, I can see four different 'solutions':
    1) Force XMP metadata to be synchronized between files with equal names
    2) Make an .XMP sidecar file for only one of the files (always the raw file, for example)
    3) Update the XMP specification to specify what should be done in this situation (maybe include the file extension in the XMP data)
    Reards,
    Simon

    Actually, I don't (notice the 'if' :)). And this is only one of the reasons. I just picked DNG as an example, to keep things simple and because it seems Adobe wants DNG to work well for photographers.
    However, the same applies to JPG and TIFF images. I often end up changing details in the metadata after the image has been finished. For example, to correct the spelling in a keyword that has been applied to half the images in my database... Talking about a nightmare scenario!

  • Proper support for Fuji EXR Raw Files

    There is still no proper support for Fuji  EXR Raw files.  On any Fuji X-series camera, the in-camera raw processing, including specifying options always outputs a far superior image that Adobe Camera Raw 6.  I've been using an X100 for some time now, and have really gathered some great images with it. But Adobe Camera Raw fails miserably to understand how to process these files.
    This is more of a complaint and feature request than a question, because I already know the answer. Adobe has not worked close enough, or at all, with Fuji to develop a Raw processor for the EXR pixel layout.
    The EXR pixel arrangement offers new possibilities, especially the ability to take an HDR image of a moving subject, and without a tripod. The elimination of the low-pass filter allows for more sharpness, and finally the noise pattern is much more "film-like".
    I've been using Adobe Photoshop for processing images for years, but have no compelling reason to upgrade without a proper conversion for Fuji RAW files.
    Adobe: Please work with Fuji to bring world-class support for EXR Raw images.
    Thank you,
    William

    Good day!
    Adobe has not worked close enough, or at all, with Fuji to develop a Raw processor for the EXR pixel layout.
    There seems to be a reason why Adobe has to reverse engineer RAW formats – the camera manufacturers don’t want their customers to use Adobe (and other) software to process their RAW files. (If their proprietary software gets better results then that’s understandable, but for how long are they going to support their own software?)
    Now maybe Fuji is more cooperative than others, but do you know that for certain?
    I've been using Adobe Photoshop for processing images for years, but have no compelling reason to upgrade without a proper conversion for Fuji RAW files.
    If the new/improved features of Photoshop CS6 have no significance for the way you process, manage, edit and touch-up photographs feel free to stick with whatever version of Photoshop you use currently, but be aware that hardware/OS changes on your side may some day make that version inoperable on your set-up.
    Also the upgrade path has been cut down to one version, if I understand correctly.
    Anyway, this is a beginners Forum, feature requests might be better posted over at

    i have a canon 70d and just purchased elements 12. It will not open a raw file for me. I have been advised to download the latest version of camera raw, i have done this and it still says my camera is not supported. I really need to open my raw files. Can anybody help me.

    You'll need to update to at least ACR 8.2 for the 70D to be recognized.  The normal way to update PSE12 to the latest CR is to use Help / Updates in the Editor which should update to ACR 8.5.
    According to Adobe's website PSE12 shipped with ACR 8.1 and you say it says yours is reported as ACR 8.0.
    Are you using PSE 11 and not 12?  PSE 11's maximum ACR version is 8.0.

  • Filter in adobe bridge to only select Raw files for DNG conversion

    Here's my problem - I have a new DMC TZ70 camera and Lightroom 5.7 doesn't recognise the .RW2 files. I would need to buy LR6! Perhaps later.
    So I thought I will import via bridge and convert to DNG.
    So I open bridge and select the camera - fine - BUT there are files for the Raw images, the same number of JPEGs and some .bdm, .TDT etc files. (e.g. 3 raw + 7 others).
    I can set up a filter to view only the Raw files when I see what files are there in the card folder in Bridge but when I select "get photos from camera" I can either select them all OR deselect and then I need to MANUALLY select the raw files. There doesn't seem to be a way of setting up a filter in the Downloader screen so that Bridge only selects the Raw files for conversion.
    If I let it select all, Bridge converts the RW2 files to DNG but also brings in the jpgs and other files. I can delete these afterwards but this seems an inefficient way to do it.
    Is there any way to manually select the raw files in the photo downloader screen?
    Advice please, thanks, Mel

    Not sure I follow completely, Mel, but Bridge allows you  to View > Sort > Type... which would allow you, after sorting, to click on the first image with a specific extension, then hold down the Shift key to select the last in  the series and  handle them independent of the other files presented.

  • Raw files for nikon d810 not showing a picture in preview. Have  camera raw plug in 8.6.0.250 . File will open in raw but no picture ahead of time.

    Raw files for Nikon D810 not showing a picture in preview for photoshop cs6 . Have camera raw plugin 8.6.0.250  File will open in ACR and process but no picture before opening raw file.

    Are you referencing Apple's Preview application or the Preview panel in Bridge?  Huge difference.
    Try purging the cache for the offending folder(s) through the Tools menu in Bridge.

  • Where can I find the plugin to open camera raw files for Nikon D810 for Photoshop CS5.1? I've looked around the site but cannot get this to work.. Thank you.

    See for yourself which version of ACR is needed for that camera’s RAW files
    http://helpx.adobe.com/creative-suite/kb/camera-raw-plug-supported-cameras.html
    then check your version (Photoshop > About Plug-In > Camera Raw).
    Your version of Photoshop does not support that version of ACR.
    You could use the free DNG Converter.

  • Camera RAW does NOT yet support raw files for the new  Canon Sureshot S95

    Camera RAW does NOT yet support raw files for the new
    Canon Sureshot S95.
    Adobe, please can you provide an update asap

    Hello!
    I think that you need to be patient.
    There has not been any release of Camera Raw since the release of the camera.
    I recommend to try the next version once it will be released, as there might be preliminary support (and therefore not listed).
    Usually, Adobe is amongs the firsts to support a new camera.
    Even though the Camera Raw team is fielded with wonderful coders, I do not think that they do have a time machine to allow support before they have their hands on a camera

    I'm interested in seeing who gets the D7100 support first? Apple or Adobe!! I will go with the one that gets it out first.
    FWIW,
    Adobe keeps a quarterly release schedule for RAW updates. The current Lightroom 4.4 RC expires on 5/31/2013 which typically is an indication that the official release will be close to that date. According to the current list of new supported cameras, the Nikon D7100 is not slated to be supported (but that could change on release).
    http://labs.adobe.com/technologies/lightroom4-4/?tabID=details#tabTop
    The most likely time frame for Adobe support of the D7100 will be sometime in August or September 2013 (although there will probably be a Lightroom 4.5 RC available prior to that for testing purposes).

  • Lightroom 3 does NOT support raw files for the  Canon Sureshot S95

    Have just bought the new Canon Sureshot S95
    after contacting Adobe support I am told Lightroom 3 does NOT support raw files for the
    Canon Sureshot S95.
    Come on Adobe.....please provide an update asap.

    (1) Well Boss I did what you said and used Canon DPP to convert to TIFFs. Choices are 8-bit TIFF or 16-bit TIFF - I chose 16-bit because part (90% part) of the reason for wanting to work in RAW is to keep the bit depth of teh original. On my EOS 40D it is supposedly 14 bits, which gives great scope to play with the levels & curves without seeing poster effects. If I choose 16 bit TIFF then each S95 image becomes a 70MB file, parallel to my JPEG and RAW.  Hardly a satisfactory solution.
    (I realise, however, that I don't actually know the bit depth of the S95 RAW file - anybody? ). 
    (2) SUGGESTION-  even if you are adding S95 support to the next update (which I dearly hope), be kinder to those with new cameras in general and allow LR to import JPEGs if it cannot import the RAWs (overriding if necessary the 'ignore JPEG' preference setting).  I am sure users with that preference would still prefer a JPEG than no picture at all!
    Since I discovered this compatibility problem, I switched the camera to record RAW+JPEG*. To my great irritation LR3 ignores the JPEGs even though it cannot load the RAWs.  So if I want to import from one supported camera (EOS40D) and one unsupported camera (S95) I have to keep going into preferences to switch on and off the 'ignore JPEG' function.
    JJ
    *  (this seems to be a setting that needs doing in the various different modes of the camera, by the way).

    Would like to purchase PSE 12 to process Camera Raw files for the following cameras: Nikon D800, Nikon DF, Canon G9 and Pentax K-3 does the Raw Converter that comes with  PSE 12 when purchased recognize  the cameras listed in the question or do I need to download  the camera Raw Version 8.3 ?

    While the G9 RAW files can be read by Adobe Camera RAW and Lightroom, these file are unsupported at this time. Here is a link to Adobe's latest list of cameras that are supported and this list came out yesterday http://www.adobe.com/products/photoshop/cameraraw.html
    I have not done a comparison between Lightroom and Canon's software but others have and say that Canon's software is clearly better. I am sure when Adobe updates their software again to include the G9 it will be a very good RAW converter as it is will most other cameras.

    Did you buy PSE in the mac app store? If not, just go to Help>Updates in the editor and update camera raw and you should be able to open the raw files in PSE 12 directly without the DNG converter.

  • Read raw files for nikon d5200 camera

    I have given up using raw files for several Nikon bodies such as the d5200 on Adobe software since Adobe no longer supports these files even with the updates that are supposed to support these files.  I can open the raw files fine using Nikon software to work on them and then save them as a tiff or jpeg to be used in photoshop, but this seems rather time consuming plus I lose the advantage of working on raw files in Photoshop.  You would think that a company like Adobe would make it easy to open raw files for all cameras.  Some bodies like the Nikon d300 raw files still work fine on Adobe software.

    ACR (Adobe Camera Raw) versions are specific to different versions of Photoshop.
    According to this link on Adobe's website regarding supported cameras
    The Nikon 5200 required at least ACR 7.3, but you need Photoshop CS6 to run ACR 7.3 It won't work with older versions of Photoshop.
    Camera Raw plug-in | Supported cameras
    You can download the latest version of DNG Converter and convert your 5200 files to DNGs that can then be opened in earlier versions of Photoshop.
    Here is the link for Windows: Adobe - Adobe Camera Raw and DNG Converter : For Windows : Adobe DNG Converter 8.4
    Here is the link for Mac: Adobe - Adobe Camera Raw and DNG Converter : For Macintosh
    The DNG Converter only works on folders of files, don't try to select an individual file to convert, Choose the FOLDER.
