UPDATE:

We're interested in what changes you would like see in our products. Do you have an idea for a feature that would help your workflow? Is there a small change that could be made to make your life a little easier? Let us know!  Share an Idea, Ask a Question or Report a Problem and get feedback from the Product Development Team and other passionate users on the Photoshop Family product Feedback Site on Photoshop.com.

In future it would helpful if you could use this thread as a means to add

"Features" that you would like to see in future releases of Adobe Camera Raw.

Please do NOT create additional new Topics and try not to duplicate requests by other users. Also, be thorough in your description of the feature and why you think Adobe should consider it.

Oh, and if you find it necessary to comment on someone's feature request/suggestion, try not to get into a shouting match. The penalty for doing so is...

b If you're asking that a particular camera is supported in a future release or just taking the opportunity to carp that yours isn't then please do so in another thread!

    What I meant with database is the possibility to built your own database, I think there is no need for Adobe providing the lens data, there will be enough enthusiasts out there willing to share the lens data they found out.

    Right now you can save your lens settings for vignetting, abberations etc, but it's at rather time consuming process to use them:
    -open up the image in ACR
    -checking the data (focal length, aperture etc) in the title bar, at the same time trying to remember which lense you used (if you have several lenses covering the same focal length)
    -loading the settings file
    -start working with you image

    If there is no lense data available in the EXIF-data the focal length can be used at least to match with a (user-defined) list of favourite lenses (mostly the lenses you own). If the focal length is covered by several lenses, ACR could ask you: "Which lense have you used for this image?"

    I am currently building a list of vignetting amount and midpoint values for various apertures and focal lengths for my lenses. It would be very nice if ACR had a way of automatically applying the amount and midpoint from a user's table of values. (Perhaps interpolating if needed.)

    It would also be very nice if each user didn't have to go through the process of trying to figure out the best amount and midpoint for each lens/aperture/focal length combination in his/her lens arsenal. (It would be great if the lens manufacturers would provide this information.)

    trcolka ...

    number "2" is, imo, a good project for third parties-- especially if it were normalized for distortion, chromatic abberations, vignetting, and sample variances. it is by no means a trivial undertaking.

    incidentally, DxO offers such a database--albeit limited to the lenses and samples they've tested. it would be helpful to integrate their database with ACR--perhaps as an extension or plug-in.

    wrt "plug-ins", i believe a plug-in architecture would be much easier to develop for once ACR is broken out from Photoshop.

    Not sure if a database is needed to counter chromatic aberration. I did some
    shots recently of the London Eye with the Fuji S2 (Google if you want to
    know what I'm talking about).

    The CA was so bad around the spokes that I was seriously thinking of
    changing to a 35mm censor camera! However, out of curiosity, I processed the
    same images in the Fuji software, which I had retired ages ago, and to my
    amazement there was zero CA. Unfortunately, as quite a few of the shots were
    strongly back or side lit, the sky was either burned out or shadows crushed
    to death and so the processed images were next to useless (the software has
    other problems too).

    From that little experience, it would *appear* CA can be corrected without
    recourse to a lens databases. If that is true, then an auto Correct
    Chromatic Aberration option in ACR that you can use on a per image basis or
    include as a default would the ideal solution.

    Shangara.

    trcolka, that sounds OK.

    On one or two occasions I have done two different conversions with different lens aberation corrections, then combined them as separate layers in Photoshop and erased selectively one of the layers. It was as though I was erasing chromatic aberation - a strange experience!

    (Unfortunately, my Pentax puts the lens model in the Makernotes, and I think ACR can't get at it! But my guess is that problem will eventually be solved somehow).

    Focus distance can be a parameter for the database and the resulting values for aberration can be at least used at starting values.

    trcolka, a comment on "2", lens databases.

    I wanted something like, but I found that my lens aberations depended also on focusing distance. For example, with a wide-angle lens I have found that I may have to do different corrections for close-up and distance subjects in the same picture.

    But if that is taken into account somehow, I agree. (I started to build a spreadsheet of initial values, but it stopped because of the above problem).

    My wishes:

    1) High Dynamic Range
    a) Save one raw-file after conversion in a linear hdr-file
    b) merge several raw-files into one hdr directly in acr

    2) Lense databases
    ACR detects the lense/camera combination from the exif-data and choose suitable values for vignetting, abberation from a database (which can be edited by the user)

    3) Open up ACR for external plugins for sharpening (e.g. Neatimage), distortion correction (e.g. PTLens) so these plugins can be incorporated in the raw-conversion process

    Both the grid and rotate crop/straighten have already been mentioned - come up with your own ideas ;-)

    It works very well but the thought came after the "if you have no crop already selected" and I was angling my head and was still wondering if it was spot on. A simple grid overlay would be a fine enhancement.

    > Echoing an earlier posting, I'd like to suggest a tool to assist straightening operations, either a grid or a drag-out ruler which would align to the crop window (not the overall image window).

    Does the straighten tool that's already in CS2/ACR not work for you? I find that tool very, very useful and fast. If you have no crop already selected, it will make a rotated crop that makes the line you drag out straight. If you already have a crop, it will rotate the crop to straighten the line you drag out.

    First of all. Thank You Adobe (Thomas) for making ACR.

    I use PhaseOne DigitalBacks and have C1PRO installed and I do not use C1 for my DSLR conversions since I find that ACR works better and are wonderfully integrated with PS and Bridge. But C1 have one feature that I miss in ACR. Custom camera profile support. If PhaseOne decides to have their backs deliver DNG files straight out of "camera", I could see myself using ACR instead of C1.

    I would like to have the possibility to turn of ACRs profiles, to be able to generate my own in GMB ProfileMaker5, and then use that profile instead of ACRs.
    Would that be possible in the future ?
