• Distortion of the Lens Correction Documentation?

  I saw in some discussions that LR corrects the distortion of the lens for a few drinks and a few cameras.  I have not been able to find documentation that indicates what cameras and lenses are taken in charge for this - for LR2.3 or 3.0beta.  This documentation is available somewhere?

  Thank you!

• Distortion of the lens presets are missing in first Pro CC 7.2.2

  The removal of lens distortion folder is missing completely. Can anyone suggest how to fix it? Maybe there is a way to download these presets separately?

  They are not lacking. It is just a beta-tester and shows you what is to come. He should have said so.

• Correction of the lens for Tamron 17-50 2.8 could be better?

  This is WITHOUT the lens profile correction.

  ... and that's WITH the lens profile correction. Not very obvious, isn't it?

  Upper right corner of a photo taken with the Tamron 17-50 2.8 at 17mm 5.6.

  The cut isn't right but a funny!

  Most likely, the slope of the cut in the corner of the image is not created by the distortion of the lens, but the camera pointing down.

  When the camera is not required to level but pointing upwards or downwards, the sensor is not in parallel with the vertical lines of the Cup. It is the phenomenon of "Scheimpflug" - google for this word and you will get many results. The phenomenon of "Scheimpflug" becomes stronger towards the edges of the image.

  That's why the architecture photographers use "see photo" where you can adjust the angle of the plane of the film or digital sensor map so that it is parallel to the vertical lines of a building.

  You can adjust the tilt of the cutting with the manual vertical slider in the Correction of the lens, and you may need to adjust the horizontal slider as well. The compromise is now, your image will be severely "trapezoidal" and it's probably not what you want.

  But you can't blame the lens profile. Profile lens corrects only distortion of the lens, no distortion by the principle of "Scheimpflug.

  PS: A tilt-shift lens will also correct the distortions of the principle "Scheimpflug.

• How can I know if Lightroom should apply the correction of the lens when importing?

  I recently imported two different sets of files raw on one week apart. The first series had lens profile correction enabled for each individual file (which would be selected by pressing the reset button), while the second set had corrections profile disabled lens (which would be not checked off by pressing the reset button). The only import setting I changed was select 'do not import suspected duplicates. Why is this different behavior? Is different based on the lenses? (first shooting with 16-50mm Sony PZ, second set taken with the 50mm 1.8 Sony).

  Figured out, it has to do with the "lens distortion compensation" setting in the camera (NEX - 5 t) at the time that the photos have been taken, I think.

• Correction of the lens and the camera in Camera Raw calibration

  My copies of Camera Raw for Ps CC and the bridge are fully updated and web support documents say that my Olympus E5 is supported by these applications. When I try to activate profile of auto lens corrections in Camera Raw, I get the warning - "unable to automatically locate the lens profile correspondent." Worse still, the drop of decision-makers does not even include Olympus. All my images include EXIF information and all my lenses are produced current Olympus. I do not understand why none of such large manufacturer lenses are supported by Camera Raw when, an app like DxO Optics Pro has profiles for all my lenses.

  Further, there is problem in Camera Raw with 'camera Calibration '. When editing. DNG. TIF and. JPEGs, the camera profile reads correctly 'embedded' for files from Olympus. However, when editing. Files of the ORF the camera profile reads "Adobe Standard" instead of "embedded".

  Is there a solution for these problems? I can't find one on the Adobe Web site.

  Richard Sharp

  Not necessarily problems:

  1. Olympus camera photo/lens combinations have been corrected for distortion inside the camera in ACR for raw and jpeg.  In general, no profile outer lens correction is available.

  2. "embedded" means non-premieres loaded in ACR, usually jpeg images.  "Adobe Standard" is the base profile provided by Adobe, all supported raw formats.  Adobe will also seek to provide the matching profiles camera, that is "neutral", "portrait", etc., for the selected cameras.

  How to use a brush to draw the shape C (above) without going through the 2 curves "informed"?

  flimpyo,

  It seems to be the Blob issue resolved by Kurt with the effect > Distort & Transform > Zig Zag (setting the size to ridges by Segment and from 0 to 100 (you can get away with less, but should not be)).

  In your version, it has probably been moved to the appearance (click on the announcement of the stroke) palette.

• Apply the lens profile in Premiere Pro?

  Hello

  I'm new to first Pro and video shooting, when I use DLSR for videos, you will notice some lights fall and lens on the lens distortion wide angle that I use.

  is there anyway to apply the lens profile in Premiere Pro, like what we do usually in photoshop, lightroom and camera raw?

  Thank you very much.

  No profile of lenses for video. You must make your own and save it as a preset.

• Correction of the lens and Raw or JPEG

  Please bear with me, I'm sometimes a little slow.

  I just loaded JPEG one friend in ACR, to see if I could fix the distortion. The image has no EXIF. The list of lenses Nikon-fit was much shorter that usual - is that because it is a JPEG, rather than a raw file?

  I was surprised that the 16-85mm lens was not in the list, as I know that it has been added to the point 6.2. After hunting for PCL files, I see that there is a RAW version only, so this fits in my guess. So, my next question is: why Adobe provides two profiles with a few drinks (raw + jpeg) and the other with others?

  I gave up to the cab and loaded the JPEG in CS5. In the CS5 lens Corrections, I was allowed to assign a raw profile only to my JPEG. It is good, but why am I here and not in ACR?

  And a smaller, but nevertheless niggling question and maybe a little off-topic, why optical Correction CS5 is offering "NIKON" and "NIKON CORPORATION" as a brand of camera, when others have only one entry?

  Yammer P, yes the list is shorter because it's a jpeg rather than crude oil, and we have several profiles for raw to jpeg.

  For all of the lenses supported in the initial release of CS5, we have created profiles for both first and jpeg. Since then, we have focused on profiles of lenses based on the crus, for various reasons (which is that we feel that we always deliver the best results of quality in this way). That of why you see some lenses supported with raw & jpeg profiles, but much more taken support with raw only.

  Correction of the plugin CS5 lens indeed allow you to choose the lens focused on the raw profiles even if it treats a file made (for example, jpeg, tiff). This will work in some cases many (but not all) for the distortion correction, but often is malfunctioning for chromatic aberration and vignette correction. I do not recommend this workflow and is a key reason we don't let the users/layout in ACR and LR.

• Remove a part of a widening of the lens

  I want to remove the part of the curve of the lens that is outside of the glasses. Don't want to hide with a clipping mask and we tried the Pathfinder commands that do not seem to work. Any suggestions?

• Reflections on the lens for iPhone

  HHey guy

  IM thinking of buying a new lens of ollioclip 4-in-1 for my iPhone 5s. So I just want to know your opinion about that. Is it really worth? and will really give me amazing pictures?

  PS - I'm not pro-photographer. But, again, I want to take take pictures on my iPhone.

  Help me guys here.

  Thank you.

  Pictures are taken by the photographer, not the goal. The lens will help with technical aspects. Take good pictures now? If so, better lenses you can of your pictures a little better. But, if you can already take good pictures, working on that, rather than spending money on more gadgets.

• What are the arrows curved left of the Inbox messages

  Would like to know the meaning of the small curved arrows colored on the left of the subject lines of incoming E-mail, and can they be used to indicate something. It seems that the purple arrows point to the left and the blues are pointing the right that I don't seem to find anything to their topic or use. Also, would have explained such as the use of the trombone and emblems star next arrows.

  Purple arrows point to the left:

  • means you have answered this email.

  blue point to the right:

  • means that you 'sent' this email to someone.
