Micro 4/3rd's lens profiles

Are there lens prfiles available for micro four-thirds lenses, in particular, a Panasonic 8mm used with an Olympus OM-d EM5 dslr?

Bob, you would need to make a profile.
However, surely it would be better to apply lens corrections to RAW images before subjecting them to HDR treatment?

Aperture 3, lens corrections and Micro 4/3rds?

Does anyone know if Aperture 3 supports the lens corrections that are part of the Micro 4/3rds spec? Presumably this is what was holding up support from being added but can anyone confirm or deny whether they actually do support it now?

I see that Aperture 3 supports the RAW format from Panasonic Micro Four Thirds cameras like the GH1 but does not support the Olympus Pen cameras like the EP-1, EP-2, EP-3. Unfortunately I own the EP-1 and have been waiting since July 2009 for an update. Since it's not in Aperture 3 I must assume that they will never support Olympus Pen cameras. Adobe's Lightroom 3 DOES support Olympus RAW and you can download a beta. I won't be moving to Aperture 3 until Olympus RAW support is there. I won't be moving to Aperture 3 at all if Adobe beats them with Lightroom 3.
WAKE UP, Apple! Either support it or let us Olympus owners that you won't.

Adobe Lens Profile Creator - ERROR (Detect corners failed because file reading errors ocurred)

1) I have successfully created a lens profile for a Nikon AF Micro Nikkor 40mm 2.8 lens used in a Nikon D5200 Camera. For this I converted the raw .nef files to .DNG first using Adobe's DNG Converter.
2) When trying to create another lens profile using the EXACT SAME .DNG files as posted in 1), I am no longer able to create a lens profile because of the message "Detect corners failed because file reading errors ocurred". I am also unable to create any other lens profile using different photos.
3) I have also tried using a fresh install of Adobe Lens Profile Creator in another mac and I get the exact same error.
4) I AM ABLE to create a lens profile if I use .jpg files (generated from the same raw .nef files as mentioned) but this doesn't help because then the profiles don't show up when trying to open a raw file in Adobe Camera Raw.
Please help as this is exasperating.
Thank you.

Thanks! I had the same error message in Adobe Lens Profile Creator 1.0.4 for OSX and I found the problem to be the letter ö in the folder name for the DNGs. The lens is an old ISCO-Göttingen and the progress stopped at 2% with the mentioned error message. Changed the folder name and now it works!

Lens Profile: designating a default.

For my 6D I took the 70-300 VC Tamron as my longer reach walkabout lens. Lightroom has a humongous number of Tamron lens profiles, several of them for every each lens, with some cryptic acronyms. Is there any place where one could find out what they mean?
Furthermore, its always a bit of a hassle to select the proper profile for the 70-300 VC lens. Lightroom always points to the much older non-VC lens. It might be a problem of the EOS-6D and/or Tamron EXIF data itself, that the brand of the lens is not recognized by Lightroom. One has to to select Tamron as the brand manually for every image.
Lightroom points than to "70-300 f/4-5.6 Di A 17E" but there exist also a profile 17N, 17P and 17F. Furthermore, below I see tro profiles for the VC version, and one more for a non-VC 70-300.
SP 70-300 F/4-5.6 Di USD A005S
SP 70-300 F/4-5.6 Di VC USD A005E
SP 70-300 F/4-5.6 Di VC USD A005N
Maybe the missing VC is a typo only. I take the A005E on a hunch, and I do not see any difference to the A005N. Maybe "E" is for Canon FE mount, and N is for Nikon's F mount?
This lens make and model issue seem to be more complicated: I used to own a 17-35 F/2.8-4 for my Nikons. The D300, and a few years later the D7000 have both recorded lens data in such a way, that Lightroom always assumed that the lens is made by Nikon: The default profile was (Make: Nikon, Model: 17-35 F/2.8-4, Profile: D700 17-35- F/2.8-4). Of course no such lens exist from Nikon, the profile was probably donwloaded by me using the Lens Profile Downloader. Maybe its author was confused about the "make of lens" versus "make of mount". The profile name might be just a string, thus Lightroom does not know that its not a proper profile. But the real mystery starts when I change the 'Make' from Nikon to Tamron: Lightroom selects than the following Adobe made profile(??):
18-200 F/3.5-6.3 DiII A14N
(Of course a battery of profiles for 18-200 exist as well.) Wow, how comes? I noted this with LR3 and LR4 already, no improvement in LR5. A profile for a Tamron 17-35 exist though in the profile list, albeit I think I also downloaded it using the Adobe profile downloader tool:
SP AF Aspherical Di LD [IF] 17-35mm f/2.8-4 o77
That's a long one :-).
I am not sure if all the issues can be resolved, considering the mix of Adobe provided, and user made lens profiles, albeit chosing a 18-200 lens for a 17-35 sure appears like a bug to me.
Can we actually select a default profile to a lens / mount pair, matching the lens in use?
Maybe the trick would be to find the profile files and to remove the profiles of lenses which we do not have?
Thomas.

There are a plethora of Tamron Lens Profiles, because Adobe provide them for Canon, Nikon, Pentax and Sony. The profiles are quite easy to find and remove, but each time you update/upgrade they will return.
I seem to recall that there have been problems with 3rd party lenses not identifying themselves properly before. I can't remember why, but I'm sure if somebody knows they will post.

Bridge missing lens profiles

Hi there, for some reason my new copy of the latest Bridge seems to only show 6 lens profiles for nikon.
Bridge has been updated to the most current update but that didn't seem to help...
Can anyone shed some light on what the problem could be here?

Yes, you only get the non-raw profiles when you process TIFF/JPEG files. FWIW I get 8, so you might want to update Camera Raw anyway.
You might not know that there are a wealth of 3rd-party profiles out there, which you might find useful. You can easily search for them online in Photoshop's Lens Correction filter by clicking the ... erm ... Search Online button.

Lens profile support in Lightroom 3 (Panasonic/Leica)

I'd like to see some "micro four third" lenses, like the standard lens of the Panasonic DMC-GH1-K, supported in lightroom 3, even though the lens shows very little problems only.

You can check to see if someone else has already created one by searching with the Adobe Lens Profile Downloader.

Pentax lens profile

I used to have a lens profile for my Pentax 10-17mm lens, but it's gone! All the Pentaxprofiles disapeaered, but I was given a link that got some back, but not the fisheye.Any help would be appreciated.
Thanks

What has changed recently on your computer? Lightroom and Adobe Camera Raw share a number of locations and functions - Raw cache, camera calibration profiles, lens profiles - so if you have uninstalled ACR in some unusually aggressive way, that might affect LR I suppose. However normally, this kind of thing is treated as user data AFAICT, and left alone. A reinstall of LR should have put back whatever needs to be there.
BTW, you do not have to match the camera body, only find a profile for the lens itself. As I understand it, the profile works the same, whatever body was used to generate it (apart from where the sensor format size is different, in which case - though this does not affect Pentax - a fullframe profile can be used with a crop sensor, but not vice versa). All Pentax profiles available (Q series or 645 aside) are going to be for APS-C crop, so any of them should work for you.
I use a K-5 and can see the 10-17 profile with Raw images, along with more than a screenful of others. I have not actively downloaded more than a couple of these, they have come from standard LR installation. These are simply structured text files; it is possible they may have been moved somehow but I don't see how. There are two locations monitored for these: one is a system (program data) location which is where the application installs or downloads them, and one in the user area where any you generate or edit as the user login, can be saved. The paths to these locations differ a little between various OS versions.
The Adobe supplied filename is: "PENTAX (smc PENTAX-DA 10-17mm F3.5-4.5 ED [IF] Fisheye zoom) - RAW.lcp" however there may be other profiles floating around in the community as well. This profile is looking for a Lens ID of "4 247".
Perhaps the lens profile is simply not being detected? There was a change made some time back by Pentax, from 2-byte to 3-byte lens ID code format (3rd byte zeroed I think) and this caused problems at the time with LR. You can manually browse to a lens and select "set default" to fix detection problems, assuming the list you see includes it. 10mm is right on the limit of what LR supports, apparently, and I believe there are difficulties any wider than that. Perhaps try with an image taken at a longer than 10mm focal length?

Canon S90 raw - lens profile overcorrect distortion

I was able to successfuly create profiles for all my Nikon gear, but Canon S90 is a completely different story. I tried all possible variations, focus distance, diferent charts, sizes, changing advanced settings and so on, but the result is always way overcorrected geometric distortion. It actually makes it worse then original. If I reduce correction to about 22% then it looks right. The same applies to available S90 profile on-line. Chromatic and vignetting models appear to be correct.
Original image:
Corrected image in Camera Raw:
I can send you zip file with original raw if you like to test it in the lab.

The S90 images are already auto-corrected for distortion based on metadata. Hence the raw images processed by CR/LR will have a similar shape to the JPEGs produced by the camera (e.g., if you shoot raw + JPEG).
At present we do not support user-created lens profiles for the S90 for raw files. This is a known limitation of CR/LR that will be corrected.
The same limitation applies to CR/LR with regards to Micro 4/3 cameras and the Panasonic LX3 / Leica DLUX4.

Lens profiles in imported tiff's

Raw files have all the lens profiles available, however, when I import tiff's I created in a 3rd party HDR program, when I choose lens profiles, it only shows a small handfull of profiles. I need the profile for my Canon 16-35 but the closest I can find is the 17-40.
How do I add the 16-35 profile?

Bob, you would need to make a profile.
However, surely it would be better to apply lens corrections to RAW images before subjecting them to HDR treatment?

GoPro Camera Raw Lens Profile settings not working for image sequence in Photoshop/AE/Premiere CS6

Hey Everyone,
I'm in need of assistance in either Photoshop CS6, After Effects CS6, or Premiere Pro CS6. I just installed the trials after seeing Russell Brown demo the GoPro Lens Profile correction feature in Camera Raw. Basically what I'm looking to do is make adjustments (in Adobe Camera Raw) to a series of still images (shot with the time-lapse mode on the GoPro) and then either export those stills through Photoshop or Bridge to a temporary movie file that will be imported into a timeline (with other video clips), or import the JPG files (with Camera Raw settings) directly into After Effects or Premiere as an image sequence. The latter would be preferable as it'd avoid the extra step of having to render the intermediate/temporary movie file.
Right now, my current workflow for GoPro time-lapses is:
          - use Bridge CS4 to do basic color correction on the still images
          - save those as TIF files
          - run the TIF files through a custom script to have Hugin 2012.0.0 (open source pano stitcher) remove the fisheye distortion
          - open the new TIF image sequence into QuickTime Player 7 (Pro)
          - export the image sequence as a QuickTime movie file
          - import the movie file into Premiere Elements 10 to place on a timeline with other video clips (as Premiere Elements can't handle the sequence(s) of thousands of still images without crashing)
If I can go directly from Bridge to a timeline, it'd save a lot of processing time (and it'd be much nicer to preview the images in Bridge without the fisheye distortion)!
I can prepare the GoPro JPG files through Adobe Camera Raw in Bridge CS6, though when I go to import the JPEG image sequence into Premiere Pro CS6 or After Effects CS6, none of the Camera Raw settings are applied. If I export the Camera Raw files in Bridge CS6 as DNG files (a step I'd really prefer to avoid) and then import the DNG image sequence into After Effects CS6, the Camera Raw settings are applied except for the Lens Profile settings -- I can pick other cameras but not the GoPro lens profiles when the DNG image sequence loads in After Effects. It also appears that once I open the DNG files in After Effects CS6, I can no longer access the GoPro Lens Profile in Adobe Bridge CS6 -- the list changes to the same list I get in After Effects. Premiere Pro CS6 doesn't let me import the DNG files at all. I've also tried to import the JPG files (as well as the converted DNG files) into an image sequence in Photoshop CS6, though it doesn't allow me to do so (the Image Sequence checkbox is grayed out after I apply the Camera Raw settings in Bridge).
There could be an issue going on with different Camera Raw versions. I didn't have Premiere Pro CS6 installed during my initial testing, though now do notice that the Camera Raw dialog in Bridge CS6 only lets me choose compatibility up to "Camera Raw 7.1 and later" when I choose to export the files as DNG. I thought Camera Raw 8.2 was an option there a couple days ago when I only had installed Photoshop CS6 and After Effects CS6 (though am not 100% certain).
Please let me know if there is some workaround to get the GoPro lens profile Camera Raw corrections applied in an image sequence in one of the Adobe CS6 products (without having to export the files as temporary TIF or JPG files out of Camera Raw). I'd greatly prefer to shorten my current workflow for these files. (I just updated the CS6 trials and have tested all three programs again though I still get the same results described above.)
Does Lightroom 5 have any option to export Camera Raw image sequences as movie files (or any other feature that might help in simplifying my current workflow)? I can't install the trial right now as it's not compatible with OS X 10.6.8. I'd consider upgrading OS X if I knew Lightroom 5 would do what I need, though am waiting for any potential color profile issues to be resolved in OS X 10.9.
I can open the image sequence in Photoshop CS6 if no Camera Raw settings are applied and then use the Lens Correction Filter to apply the GoPro Lens Profile settings, though I really prefer the Camera Raw interface in Bridge for tweaking image settings. As soon as I apply Camera Raw settings to the first image, Photoshop CS6 grays out the image sequence checkbox.
If there isn't a way to take Camera Raw files straight from Adobe Bridge to a timeline, I may stick with my current workflow using CS4 and see what I can do to better automate some of the steps as the TIF export in Bridge, fisheye distortion removal in Hugin, and render in QuickTime Player all take quite a while. I won't mind waiting for all the processing if I can set it and check back on it in later the next day when it's fully complete. Is there a way to have Adobe ExtendScript execute an external shell command (i.e.: a command I could type into the bash shell in Terminal in OS X)? If not, is there a way to call/run an ExtendScript script from the command line and pass a parameter to it that my custom script could use?
Thanks in advance,
Mark

Can you zip up a few of your GoPro images, upload them to dropbox.com and post a share link, here, so others can experiment with them, or do you mean this issue is global to all camera models?

Lightroom Bug: with GoPro Hero4 Silver Lens Profile, crop settings do not sync properly in Lightroom 5.7.1 when Constrain To Warp is checked

I was having a bit of difficultly in getting crop settings to properly sync in Lightroom 5.7.1 (running on OS X 10.10.1) when Constrain to Warp was checked. This appears to be a bug in the latest version(s) of Lightroom that include(s) the GoPro Hero4 Silver Lens Profile settings. I'm working with a lot of files from a GoPro Hero4 Silver camera shot in the time-lapse / interval timer mode. All of them are horizontal with the same resolution (and dimensions). I've tried various sequences to get this to work in terms of using Auto-Sync, resetting the settings on all images except one and then copy and pasting settings, etc, though the crop is not properly syncing regardless of what I do.
Here's are instructions of how to duplicate this issue (there are some extra details/steps here, though this should be clear enough to produce the same result):
     1. in the Develop settings for a single selected image, go to Lens Corrections, click to Enable Profile Corrections (in the Profile tab), and then pick the GoPro Hero4 Silver Edition (Adobe Profile) if it is not automatically chosen for you (if you are using files from a Hero4 Silver camera). After this, click on the Manual tab, and set the Scale setting to 76. (as you will see, you now have the full horizontal width of the image that was getting cropped off, though you do see white around the edges that have been warped/shaped to correct the fisheye distortion)
     2. Press the R key (or click on the Crop Overlay tool just below the histogram). Change the Aspect option to Custom. Click to unlock the lock next to it (this seems to re-lock after setting to custom even if it was locked before). Place a checkmark next to the Constrain To Warp option. (At this point, you'll see the image gets cropped back to an approximately 4:3 ratio and the full horizontal width is not included in the cropped area) Click the upper right most corner of the crop area and drag as much to the right and top as it lets you go. Do the same for the lower left corner, dragging it as far to the bottom left as you can go. (Now, you will see that your cropped area is the maximum rectangular width and height you can select without getting any of the excessive white area) Click the Close button (or press R again) to leave the crop overlay tool.
     3. Press G to go back to the grid of images. Make sure the image you just adjusted the settings for is the only one selected. Right click on it, go to Develop Settings, and click Copy Settings. Click Check All on the window that appears and then click Copy.
     4. De-select the image you were working on. Select multiple other images in the grid. Right click on one of these, go to Develop Settings, and click Paste Settings. (at this point, you will see their aspect ratio has become more panoramic than the 4:3 aspect ratio the images previously were)
     5. De-select these images. Select one of these image, and then press D to go to the Develop settings for this image. Press R to go to the Crop Overlay tool. Here you will see the bug where the crop was not properly copied over from the first image. The selected area is smaller than the full width and height available to crop.
It seems that the bug is that Lightroom is only copying the aspect ratio (and the other settings), but not the actual crop selection.
I just thought of a workaround that I've tested and can confirm works (and will also work in a slightly different workflow than above). In step 1 above, for the Model (and Profile), manually pick the "GoPro Hero4 Black Edition" or the "GoPro Hero3-Silver Edition". If using the "Hero3-Silver" setting, the Scale (also in step 1 above) need only be set to 79 (rather than 76 for the Hero4 profiles). By picking one of these Lens Profiles and doing everything else the same as the other steps above, the crop settings do copy and paste properly. This does also appear to work properly when selecting the "GoPro Hero3-White Edition" Lens Profile, with a Scale setting of 75, which yields a slightly more rectilinear image (with a wider aspect ratio -- almost, but not quite 16:9).
While this isn't too big of deal as it does work by picking one of the other lens profiles (and the Hero4 Black Edition profile appears to make the same exact correction to the image), this was incredibly frustrating last night to notice that some files had the proper horizontal field of view / crop and others didn't, and other users may experience this or not even notice their crop is not copied properly (as, depending on one's composition and image, it's not extremely obvious with such a wide view).
I hope this discovery helps someone else and provides feedback for Adobe to correct this issue in the next version of Lightroom 5.
On a separate, additional note for Adobe: Please allow the crop overlay tool to "crop" an image to a size that is larger than the original dimensions of the image. This would allow for one to retain maximum original sharpness in the center of the image when using the Lens Profile tool to correct, or "de-fish" a lens, without having to scale the image down with the Scale option on the Manual tab of the Lens Corrections settings. For example, when I do the above process selecting the Hero3-White Edition profile, my final image dimensions are 3840 by 2257 pixels, reducing the size of the image in the center by 25%. If the tool allowed one to crop/scale a larger image size, and I kept the Scale option of the Lens Corrections settings at 100 rather than 75, my final image dimensions would be 5120 by 3009 pixels (larger than the 4000 by 3000 pixel dimensions of the original image which the tool now limits me to). Yes, the edges would be a little softer but the center would retain the original detail. (this is essentially what the Calculate Optimal Size button found in the Hugin open source software does, when using it on a single image for lens transformations/corrections)

Can you zip up a few of your GoPro images, upload them to dropbox.com and post a share link, here, so others can experiment with them, or do you mean this issue is global to all camera models?

How is the best way to capture frame in Lens Profile Creator?

Hello, I read in the Shooting Guide related to Adobe Lens Profile Creator:
When framing the chart in different areas of the image frame, use a combination of physically moving and tilting the camera to achieve an optimal balance for LCP generation.
i. Only moving the camera to frame, so that image plane stays perfectly parallel to the chart, can have an adverse affect on LCP calibration data.
ii. Only tilting the chart may cause depth-of-field issues, where part of the chart may go too far out of focus due to the large angle of the chart in regards to the image plane. This can also have an adverse affect on LCP calibration data
Ok, but I'm not able to understand at all, please help me:
1) is it better if I'll rotate the camera on tripod to left and to right or is it better phisically moving the tripod to left and to right?
2) is it better if I'll tilt up or down the camera on the tripod or it's better picking up or down the tripod bar?
3) if it should be better make a combination of tild and rotate and move the camera how can I know the optimal combination?
I hope that someone who has experimented this could explain me better
Thank you everybody
Damiano

I don't know what is technically optimal, but there is an aspect of practical convenience here, as well.
In my experiments with this, I physically moved the tripod in the left-and-right direction, and then re-aimed the camera vertically as required in order to put the target into the desired part of the frame. I was happy with the results, though I did not make any deep comparative study.
IMO whatever technique permits you to make a sufficient variety of reasonably careful acquisitions, without being unfeasibly difficult, and which the analysis tool does not reject, is probably going to be good enough.

Why don't additional downloaded lens profiles show up in LR5?

Hi everyone! My name is Kai and this is my first post here. Normaly I find an answer to all my questions by reading already existing discussions. But this time I wasn't lucky...
Hopefully this is not a stupid question.
I downloaded lens profiles for the Rokinon 7.5 fisheye and created a folder named "Rokinon" in "Rsources", "LensProfiles", "1.0" (MAC OS) to put them in, but they don't show up in LR5 and I can't use them. What's wrong?
Thanks, Kai.
<moved by mod from downloading,installing,setting up - kglad>

The correct location to place downloaded Lens profiles on a Mac is:
Macintosh HD / Users / [your username] / Library / Application Support / Adobe / CameraRaw / LensProfiles /

How do I create an ACR custom lens profile if camera exposure can't be set to manual?

How do I create an ACR custom lens profile if camera exposure can't be set to manual?
I ask this question for the Nokia 808 PureView 41MP camera. It produces stunning image quality but exposure can only be controlled via EV +/- compensation. I need a lens profile to correct for vignetting to get even skies in panorama (which turn out stunningly otherwise). There is no profile for the Nokia 808 PureView I am aware of and I'd like to produce one.
Is the Adobe profile creator able to correct for varying exposure using EXIF or overlapping parts of the chart or background?
Or would the Adobe profile creator ignore EXIF if I use studio flash to enforce a constant lightning situation, even if shutter speed would vary (aperture is constant and ISO can be set constant, just not the shutter speed)?
Or did Adobe produce a profile internally they can share?
Thanks.

If you read the first post, this is the camera-app of a 41MP Nokia Pureview 808 camera-phone, so maybe someone could write a new camera app but the phone is Symbian OS which is dead, making that unlikely.
http://www.digitaltrends.com/mobile/the-skeptics-guide-to-nokias-808-pureview-five-reasons -41-megapixels-are-not-a-gimmick/
http://www.digitaltrends.com/mobile/the-nokia-lumia-820-and-lumia-920-too-little-too-late/
It would probably be easier for Adobe to rewrite the LPC to allow vignetting to be computed from a single shot of a blank wall without a target in the shot, than to have someone rewrite a camera app that allows manual exposure.
Another idea about how to get the phone to keep a constant exposure would be to experiment with putting darker and lighter objects in the field-of-view away from the target area to make the camera metering adjust things so it’s exposure is the same from one shot to the next. This would take some doing but should work, unless the LPC uses the part of the frame that doesn’t contain the checkboard target in its computations.
You’re basically varying the scene around the target so the camera takes the same exposure of the target each time.

Error installing Adobe Lens Profile Dwonloader 1.0.1

Hello,
I am trying to install version 1.0.1 of the Adobe Lens Profile Downloader. However, every time I double click on the .air file everything goes fine right up until I click the continue button and it tries to install it. That is when I get the air mess that says "Sorry, an error has occurred. The application could not be installed because the installer file is damaged. Try obtaining a new installer file from the application author." I have tried downloading the file several times and nothing. I have tried uninstalling and reinstalling Adobe Air and not go. Any suggestions?
Thanks,
