Lens Profile Correction - Pentax SMC DA 18-270

Does anyone know where to get the plug-in to use the auto lens profile correction in Lightroom for the above stated lens? Adobe only have the older 18-250, and even on the new 5.3 LR version, still have not supplied the plug-in for this lens!

LR doesn’t use plug-ins for lens support. The support is either built into the program or contained in external .lcp files that each new version update adds a few of.
Looking at the new lenses supported for the ACR 8.4 release candidate at Adobe Labs, which would presumably be added to LR 5.4, I don’t see the lens mentioned as newly added:

Looking in the Adobe Lens Profile Downloader, for lenses that third-parties (users like you and I) have supplied, I don’t see any 18-270 listed, either.
What camera are you using the lens on?

Adobe Camera Raw Save Settings and Lens Profile Corrections Help

I have been fooling around with Adobe Camera Raw’s (ACR) ability to save settings so that I can apply them to other images. I’m able to set things such as clarity, vibrance, camera profile etc. What I want to do is enable Lens Profile Corrections and have it automatically detect the lens information for future images, apply no distortion corrections and apply vignetting and chromatic aberration corrections. However, when I try this, the Lens profile sticks on “Canon EF 24-105mm f/4 L IS USM” (which is what I used for creating the settings to be saved) regardless of the lens used for the image that I am applying the settings to. Is there a way do this?
I’m using Photoshop CS6 and ACR current version.
Thanks,
Mike

You should see an Adobe Standard profile and perhaps an ACR x.x profile for your camera, but Adobe does not make Camera-centric profiles (landscape, portrait, camera neutral, etc) for most cameras unless they are Canon DSLRs, Nikon DSLRs, one Leica and a few Pentax cameras.
On a Vista/Win7 system you can verify what models of cameras are supported by Adobe by looking for profiles in:
C:\ProgramData\Adobe\CameraRaw\CameraProfiles
The lens profiles are in:
C:\ProgramData\Adobe\CameraRaw\LensProfiles
There are comparable directories on Win XP.

After upgrade to lightroom 4.3, my canon 7D is not showing up in lens profile correction

I think this happened after upgrading to lightroom 4.2, but I am not sure as I haven't used Lens profile correction in some time.
When I enable the "Enable profile corrections" checkbox in "lens corrections" The Make and model of the lens is recognized, but the profile field has only 2 optoins, "canon EOS 1D MK III" and "Adobe". It does not have any other options including the EOS 7D that I use. Tried uninstalling and installing again, that didn't help.
I found in the forum that for Win 7, lens profile is supposed to be stored in "C:\ProgramData\Adobe\CameraRaw\LensProfiles\1.0", in my case the LensProfiles directory does not exist. There is a CameraProfiles directory(C:\ProgramData\Adobe\CameraRaw\CameraProfiles).
How do I solve this?

There is nothing wrong with your lens profiles.
The issue is that you are adjusting a JPG not a raw file. When adjusting raw files the camera model is not listed with the profile because it doesn’t matter and all of them say Adobe as their source for Canon cameras at least, but when adjusting JPGs the camera may have done certain adjustments internally so it does matter and is why you see the wrong lens-distortion occurring when choosing the 5D Mark III profile with your 7D JPGs.
For the record, I have profiles in both the locations mentioned: under Program Files\...\CameraRaw and under ProgramData\...\Lightroom 4.x. This makes sense because I have both Photoshop CS6 and Lightroom installed. The ones under Lightroom are all dated 12/2012 while the ones under Camera Raw are mostly dated 2/2012 with some from 11/2012 and other dates. The profiles are probably the same, but the Camera Raw ones retain the date of the original profile creation whereas the Lightroom ones all get updated to the same date. Lens profiles can also be installed with the DNG Converter, although I'm not sure which of the two locations those install to.

Lens profile corrections unresponsive

I need a hand in troubleshooting the following:
The last time I accessed my catalog I was able to use the automatic lens profile corrections feature of Lightroom. Now, I am unable, and get the error message stating that Lightroom is unable to locate a matching profile automatically.
I'm using supported equipment (Nikon 24-70 / 70-200) and the lens shows up in the EXIF data as viewed in Lightroom.
At first I thought this was a result of first using Photomechanic to caption my images but when I attemped to import into lightroom directly from the card, the same thing happend.
Any ideas?

Profiles are not presets, they are stored somewhere in a shared system directory. Camera Raw shares the same location for profiles, that's why uninstalling CS5 removed the profiles.
Reinstall Lightroom.

Camera Raw - Lens Profile Correction

I'm just beginning to work with Photoshop CS5. When I was editing with the camera raw features; I discovered that there had not been a "Lens Profile Correction" loaded for my Panasonic Lumix DMC-L10 with a Leica lens 14-150. I"m looking for a method to get this lens added to the Profile Connection.

You could also check out Adobe Lens Profile Creator if the lense has not profiled yet.

Lens profile corrections in Lightroom 3.6

I use Lightroom 3.6. The "lens profile corrections" does not have my lens in the drop-down menu. Is there a way other than using the Adobe Lens Profile Creator Tool to create this profile? The lens is the Nikon AF-S DX NIkkor 18-105mm F3.5-5.6 G ED VR, and I use the Nikon D90 dslr. I only shoot JPEGs.

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

How do you get custom Default Settings to enable lens profile corrections automatically on import?

I have created default settings by serial number for my Canon Mark III 1ds which include enabled lens profile corrections. I then created a user preset with these default corrections. Next I imported a folder of RAW images shot with this same Canon camera with the user profile checked as part of the import. When I switch to the Develop module and check the Lens Corrections panel, I see that although it is checked for each file, the actual make, model and profile are not populated.
Is this a bug or am I overlooking something on import? I understand that in LR 4, you can apply specific lens and camera calibration profiles to camera serial numbers (noise reduction etc too).
MacPro 2.8 Ghz Quad-Core Intel Xeon with 16 gigs of ram running OSX 10.7.2.

You can make your defaults specif to ISO and/or Camera Serial or not (see Preferences), but what you choose is valid for all default parameters. You cannot say "use my NR ISO-specific, but the rest of the parameters regardless of ISO".

ACR won't automatically identify Lens Profile Correction even though lens can be manually selected from drop-down

One of my most-used lenses is the new Canon EF 16-35L f/4.0
It does need lens profile correction; but Adobe Camera Raw isn't automatically loading it, as it does with all my other L lenses.
I can manually pick the lens from the list, so the profile has definitely been loaded, but manual selection takes time, and time is bad for workflow.

If that lens profile is indeed the proper one for your lens, rather than something being slightly different and why ACR isn’t selecting it, then the situation is easy to fix:
When you have a raw photo open that was taken with that lens, then in the Lens Corrections / Profile tab, first choose the proper lens profile, then under Setup, choose Save New Lens Profile Defaults. That should tell ACR you want it to choose that profile whenever it sees the lens the current raw file was taken with.
For this to work your CR defaults for photos opened with that camera need the Lens Corrections / Setup default set to Default and not Auto. Auto will skip the manually-defined defaults and Default won’t.
To set the Camera Raw defaults open a new raw photo that doesn’t have any adjustments, set the Lens / Setup to Default (rather than Custom or Auto) and choose Save New Camera Raw Defaults from the menu that appears after clicking on the small icon at the right of the Lens Corrections title bar.

Apply lens profile correction on import?

Am I alone in wanting the option
to apply automatic lens profile correction upon import?

You can either use Develop preset on import, or create a custom camera default. I do the latter. For example, all my imported 5D images have lens corrections enabled by default.

LR3 Blacks out corners in UWA Lens Profile Corrections

Hello all,
I am fairly new at all this, so please forgive me if this question is ridiculous, but I cannot seem to get to the bottom of a particular issue. I recently went on a trip with a new Nikon D7000 and Sigma 10-20 f/4-5.6. Most of the pictures (all RAW) with the Sigma turned out great. LR3 properly applied the automatic lens profile adjustment for those shots and ironed out most of the distortion. However, one photo turned out very weird. It looked like I shot through a tube, the extreme corners were totally blacked out (think 100% vignetting).
I thought this was weird, especially because it looked ok on the back of the camera. Sure enough, it was perfect when I opened the RAW with the Nikon software (and on the back of the camera) no blacked out corners. Confused, I turned off the auto profile adjustment for the lens on that image and the corners immediately came back. Its an artsy shot, so I am not too concerned about the loss of lens correction, but now I am concerned that some random image will show this problem down the road. I have attached a picture of the jpeg exhibiting the problem, and a link to the RAW so you can try to replicate it. I tried OTHER lens correction profiles and they all worked fine (no blacked corners). Any idea what might be causing this?
Thanks in advance

I downloaded your image and get the same result. It would seem that the profile is defective. I'll submit the bug report.

Lens profile correction applies severe crop

Canon 5D MKII with Canon EF 100-400mm lens set at 100mm. When using the standard Adobe lens correction profile that comes with LR3.2 there is a severe crop of about 50% applied to the image...but not with every image. Very strange.

Thanks Ian. Here's a link to a page with the file on. WARNING - the file is 19MB. It was shot as a Small RAW.
Grateful if you could let us know the outcome.

Why are no Pentax lenses in the Adobe Camera Raw lens profiles when processing JPG files?

I normally shoot and process raw files and use the latest version of Adobe Camera Raw for processing. Some of these files are converted to jpg for use on the net or e-mailing etc. Sometimes I want to make minor changes to the now converted jpg file and often go to Adobe Camera Raw for ease and speed of use. Lately I have gone back to some files that were not thoroughly processed as raw files before conversion to jpg. When, in ACR, I go to Lens Corrections panel, Profile tab, I Enable Lens Profile Corrections and choose Setup: Auto (or Default) and get the message, "Unable to locate a matching lens profile automatically".
I then go down to Lens Profile and click on Make with the intention of choosing the Pentax lens which I used for the photo. Here is the problem - there are only six choices under make, namely Apple, Canon, Nikon, Sigma, Sony and Tamron. I have no such issues when processing a raw file in Adobe Camera Raw. Pentax lenses are automatically detected and Pentax, along with Leica, Samsung, Zeiss, etc. are choices under Make of lens.
Do other people have this problem? Is there some setting I have missed? Is Adobe just not permitting some makers' lenses, for which there are profiles, to be corrected if the files are jpgs?
BTW, I have checked and the same issues exist for tiff files opened in ACR.

Assuming I read your post correctly, and that you're trying to use Lens corrections on JPEGs and TIFFs... I believe there's a completely different set of profiles for correcting already "developed" images (such as JPEGs and TIFFs). If I recall correctly (and it's been a while since I read about this), it's the same set that's used inside Photoshop for the Filter - Lens Correction tool (I hope someone here will correct me if I'm wrong, but I'm sure I read this somewhere).
If your lenses are known to Camera Raw when you develop raw files, I suggest you will need to go all the way back to your Raw file and reprocess it from that stage. You'll get a better result anyway.

Decision-making process EXIF = correct lens profile

I created a lens profile for my new camera Sony SLT-A77 with lens SAL-1680Z.
I use ACR 6.6 with activated feature "Enable Lens Profile Corrections" and Setup = Auto.
My new profile is found automatically because of EXIF information in the DNG file
and matching tags in the lens profile file.
EXIF:Make = stCamera:Make = "SONY"
EXIF:Model = stCamera:Model = "SLT-A77V"
EXIF:Model = stCamera:CameraPrettyName = "SLT-A77V"
EXIF:LensModel = stCamera:LensPrettyName = "DT 16-80mm F3.5-4.5 ZA"
But my problems start with the second lens. This is Tamron SP 70-300mm.
There is a lens profile provided by ACR 6.5: "SONY (TAMRON SP 70-300mm F4-5.6 Di USD A005S) - RAW.lcp"
But the tags in this file aren´t matching the EXIF in my DNG files.
So I tried to edit the tags like in my own lens profile.
EXIF:Make = stCamera:Make = "SONY"
EXIF:Model = stCamera:Model = "SLT-A77V"
EXIF:Model = stCamera:CameraPrettyName = "SLT-A77V"
EXIF:LensModel = stCamera:LensPrettyName = "TAMRON SP 70-300mm F4-5.6 Di USD A005S"
But in ACR6.5 this profile isn´t found automatically. I have to choose manually
in the Lens Profle menu the Make selector. But I have to choose "Tamron".
I can´t understand this behavior because the tag is stCamera:Make="SONY" and
there is no tag with "Tamron" in the profile.
I deleted all other lens profiles on the computer to exclude problems with another lens profile.
In the document "Adobe Camera Model V1.0" on page 11 I found the required EXIF tags,
but I suspect the mechanism ACR choose a lens profile is different.
Ingo

There is also a LensID field in xmp:aux that would affect the lens matching. Bring your photos in PS/Bridge, show the FileInfo dialog, go to the Advanced panel, you can tweak the metadata in the lens profile to match the same values shown in the FileInfo dialog.
