LightRoom 3 - the Perspective Correction

Similar Questions

• The perspective correction.

  I'm an architect and take lots of photos architecture wide angle.  I am a user of Aperture on a mac.  At the opening, I can straighten a photo but I can't correct perspective distortion.  I was told that this is possible in Lightroom.  Can a user of Lightroom tell me how it's done and if it's easy and done well.  I would love to see a before and after.  Thank you.

  I could tell you, but Julianne Kost does a much better job

• How to cancel the _automatique_ perspective correction?

  I use the latest version of Camera RAW and Photoshop CS6 (13.0.6).

  When I open a RAW file, the Camara RAW applies automatic perspective corection.

  I want the correction of chromatic aberration and optical aberration correction, but NOT from the perspective correction. What should I do?

  In camera raw if you choose the default Camera's Raw, that get rid of correction?

  (I can't get what your getting if I open the image in photoshopp cc and use a standing choices under the correction of manual lens, cs6 does not)

  Did occur to each picture you took with this combo of camera and lens?

  Have you ever had a trial of photoshop cc installed?

• Help on Perspective correction, Image stitching and then pattern matching.

  Hi all

  As a newbie in LabVIEW, I don't know a lot about machine vision.

  I need for my project automation, stitching the images (from 4 cameras, 90 degrees). Do the perspective correction and then form a label (which is actually pasted on the jar).

  Please share your experience on the same type of project. And help me to proceed with the development of the project.

  Also find enclosed all the pictures from the camera.

  PS: Due to budgetary constraints, I use very basic USB cameras available, and the attached picture is the actual image.

  To be able to correct the image for distortion, you first have to calibrate it. Assuming that your setting of the camera is constant (i.e. the bottle always at the same place in what concerns the cameras, I would first of all paste a grid around the bottle calibration and then take a few pictures of this grid with all four cameras.)

  We install a calibration grid, you can print: C:\Program Files (x 86) \National Instruments\Vision\Documentation\CalibrationGrid.pdf

  This example will then show how you can learn the calibration using the images of the grid, and then the correct images would have taken you without the grid.

  \LabVIEW 2010\examples\Vision\2. Calibration Example.llb\Nonlinear Calibration Example.vi Functions\Calibration\Nonlinear

  Note that you need to recalibrate the system if something changes (lens focus, camera or bottle of position.

  After this step, you should have 4 images 'straight' which have been corrected for distortion and which can be used for sewing.

  For sewing, unfortunately, Vision Development Module does not include an exit of the seams of box function.

  If this is acceptable, you can use some third party software that provide features couture, such as Photoshop Autostitch, Hugin, Ptgui, Panorama Tools, search for Microsoft Image Composite Editor, CleVR Stitcher or Adobe Systems.

  If you need to do everything in LabVIEW, I can point you to some of the tools provided with the library you can use to create your own algorithm of seam. This part is certainly the most difficult of your project.

  Image stitching process can be divided into three major components - image calibration, registration and fusion. We already talked about calibration.

  -Image recording is to couple features in your images in order to align them. You can use tools like the corresponding model and edge detection for this purpose Watch examples of vision LabVIEW to know how to code in LabVIEW.

  -Image mix is to process the images to account for the difference in brightness of images from several cameras.

  Histogram analysis on the different images and applying a lookup table are simple tools that you can use for this purpose.

  Images can then mingle with features like IMAQ ImageToImage.

  This thread also talks about sewing:

  Hope this help get you started. Good luck with your project.

• Lightroom applying not automatic correction of the lens for M43 objectives

  Forums, there are many discussions about the automatic application of integrated objectives M43 profiles.  My problem is that Lightroom does not apply the profiles of builtin for a camera of the MDGs - em5 olympus (lens panasonic lumix 14-140 3.5 to 5.6, kit olympus 12-50), panasonic gh3 (objective 14-42).  I use of course raw format images, and I've tried Lightroom 4.4 and downloaded the latest Lightroom 5.7.1.  I started fresh with new catalogs and in each case, I have the same result.  When I go to develop and lens Corrections is NOT showing me the info button saying that a built-in profile has been applied.  ACTIVATE the PROFILE CORRECTIONS is NOT selected.  My study of the forums of the Info button should be there, but it's not.  Any ideas?

  I'm not absolutely sure, but I think that the info was introduced with LR6.

• Goal not recognized by Lightroom despite the profile of lenses available and correct metadata in the RAW file

  Hi all

  In Photoshop Lightroom CC (latest updates installed - v2015.5) my Tamron 15-30 mm f/2.8 lens is not recognized, only an opportunity for the focal length and aperture are visible.

  The profile of lenses must be selected manually - but even after selecting the lens information are not available for the photos in the library module, so I can't search/filter for this purpose.

  In the RAW files from my Nikon D750 written in the metadata correctly: target = 15-30 mm f/2.8 and LensIDNumber = 233.

  Funny enough for the 24-70mm f/2.8 Tamron everything works-> his profile is automatically recognized in the develop module and I can / filter to search for it in the library module.

  Any advise?

  Thank you and best regards,

  Meik

  Not correct.

  Nikon d5500 has been added RAW NEF photos are indeed compatible with the current version of Lightroom (6 Lightroom or Lightroom CC 2015)

  Unfortunately, the toolset is not so advanced that LR would prefer being able to edit my photos out there. Any suggestions as to why it cannot interpret the correct values in files? Camera Canon G15 btw.

  If you use the auto white balance setting in the camera it is remove the Green tint in the embedded preview raw file (JPEG files). LR White Balance tool is more limited in range compared to the correction of the White Balance in the camera. On your screenshot posted the tint WB slider is set to 150 (Magenta), but clearly it is not sufficient to correct the under cast of green water. You can create a custom profile of DNG to extend LR Temp WB and range of hue as shown here:

  Lightroom: Setting the white balance for underwater photography

  One of the Green images issued by export to the DNG format and open it in Adobe DNG Profile Editor. The corrections described above and then name and save the new DNG profile in below the location of the folder. Restart LR to load the new profile of the camera.

• How can I use an image fixed outside of Lightroom in the corrected version?

  For a photo Album I want to use some photos from Lightroom corrected in an application from a vendor of the album. By selecting these pictures I still have the original and not the corrected version in the present application. How can I get the versions corrected for other uses?

  Please mark resolved issues as such. This makes it easier for others to find solutions and the "help" identify already solved threads. Thank you.

• Transform objects correctly with the perspect of an object in a picture

  Consider the following example, I'm putting the text on this view in the same proportions that she initially, but with the perspect of the display of the image:

  

  I always make a complete mess of what I can never guess guidelines virtual perspect and eventually stretching of the image (as you can see that the word 'text' appears pixelated). Of course I could do it but it would take ages.

  Y at - it a better way to make this work? Also, is - anyone can correct and download the correct image for me using the .psd to http://1drv.ms/1l2BKZF file?

  I don't see anything problematic here. You are simply munching just around and re forget that text transformation encompassing is not equal to the size of the screen. Of course, get shit when you overdo the stretching in one way or another. You can try the course Vanishing Point filter, but this really isn't a technical problem, but rather a more general lack of experience and knowledge of perspective drawing. Taking a class of art on the subject won't do more for you that stir things up by with experimental clicking and pulling...

• I have to use the lens correction in lightroom 5 if I activated behind closed doors?

  Do I have to use the lens correction in Lightroom 5 develop module there I activated behind closed doors? (Canon 5 3)

  Your camera (if on) lens correction in JPEG format, will not apply for RAW files. Clearly, you don't want to apply twice.

• My lightroom does not open. I get an error message saying "windows cannot find"C:\Program Files\Adobe\Adobe Lightroom\lightroom.exe". Make sure you typed the name correctly and then try again"when nothing is irrelevant.

  Please help me. I uninstalled all lightroom related and reinstalled and nothing works!

  Hi noelc,

  This is related to the problem of association of files on the Windows platform. Other applications works very much like Photoshop.

  Please completely including current uninstall Lightroom and the old version of it.

  Restart the Machine (very Important)

  Reinstall the application from Creative Cloud Desktop App (disconnect & connect away from getting the latest version of Lightroom)

  Kind regards

• 6 Lightroom does not start correctly

  LIghtroom 6a fonctionnee om my 10 (x 64) of Windows without problem for 6 months. After the installation of a slide (CyberViewX) scanner and a regular update to Win 10 that occurred automatically when closing down the computer, the 6 Lightroom does not start correctly since I restarted the computer. I uninstalled the scanner CyberViewX program and rebooted the computer again. The only thing that happens when you try to open LR6 is a message that an error has occurred when opening the catalog. I do not have a backup catalog, and there is a button where I can choose a different catalog. When you press this button I find the backup catalog, but when I chose this catalogue I go back to the original message and the backup catalog was obviously not chosen. There is a button to create a new catalog as well and when I press this button I just in my photo folder and there seems to be no way to create a catalog or open LR6. This form of dialogue is obviously not working correctly.

  There was a lock by the catalog file, and I deleted this file. I also tried all the tricks LR running as an administrator and assign full privileges for all users of my photo file.

  The only thing I have not tried is to uninstall and reinstall the whole LR6, but I have a lot of photos and work so I hesitate to do this without knowing that it is necessary and if sure that I can get everything back in order with the old catalog and all restored. Anyway to fix corrupted with the installation DVD files?

  What should do? Help!

  Hi bjomb,

  You suggest to choose the option to create a catalog and give it the name once you get the pictures folder window, and then choose create.

  This would create a new catalog.

  check if it opens the new catalog, and it passes under the background processes in the Task Manager.

  If it does not, then you need to reinstall Lightroom program and it would not affect your changes as changes are stored in the catalogues and catalogues remain it is same when the resettlement.

  Kind regards

• Why Lightroom changes the date and some of my images on their import

  Why Lightroom changes the date and some of my images on their import

  The problem is that when I try to put photos in subfolders (depending on date) Lightroom some if put in the incorrect date - 10 hours AHEAD of the actual time that the photos were taken (according to the data from the camera).

  This is a bug for a long time in LR: Lightroom: import: folder names arrange by date around midnight of evil when using USB camera

  You use a USB cable to connect to your camera?  Try to take the memory card from the camera, put it into your computer's card reader and import from there.  It solves the problem for most people.

  I tried to move photos into their correct date subfolder, but then of course Lightroom cannot find more!

  Move photos within LR, instead of in the Mac Finder / Windows File Explorer.

• Ideas to explain why, when you work with raw files in LR 2015 with Edit in PS 2015 and use the Camera Raw filter, the profile in the Lens Correction Panel tab is missing

  Ideas to explain why, when you work with raw files in LR 2015 with Edit in PS 2015 and use the Camera Raw filter, the profile in the Lens Correction Panel tab is missing? Mac OS X 10.10.5.  I reinstalled the OS and Lightroom and PS, nothing helps.

  Hi ParadigmRose,

  This is expected as profile tab behavior does not appear under Lens Correction Panel if you go to Camera Raw Filter in Photoshop

  However, profile tab would be there if you open a raw image directly in camera raw first.

  You can go to the filter menu > Lens correction in Photoshop, if you want to search for profiles with edit in Photoshop.

  Kind regards
