CS6 Lens correction question

Please forgive me if this has been answered, but my searches provided lots of discussions that did not address my question.

How do I apply lens correction?

  1. Open image (in this case JPEG - not RAW)
  2. Open Filter > Lens Correction
  3. The lens correction window opens
  4. The metadata attached to the file matches no known profile
  5. PS has pre-selected the make (in this case Nikon) but not model or lens
  6. I select the model (although the camera, a D3200, does not appear in the pulldown, the D3300 with the same sensor does appear, so I select that)
  7. I select the lens (although the lens, a Rokinon 10mm f/2.8 does not appear in the pulldown, I select what appears to be a generic version of this lens)
  8. PS has applied changes to the image in the Lens Correction window with each choice, although the Lens Profiles says "no matching profiles found").
  9. Using the "search online" feature returns no results that match this camera/lens combo
  10. Clicking "OK" does not apply the changes from the Lens Correction window to the main PS window.

    What am I doing wrong?  Why are the changes in the Lens Correction window not being applied to the main window?
    Do I have to create a custom profile for this camera and all my lenses?

For some reason even in the newest camera raw which is supposed to support that lens, camera raw always seems to think the lens is 14mm instead of 10mm.

Anyway, a solution for now with photoshop cs6 is to download and install the latest adobe dng converter, which installs the newest adobe lens profiles, which include your lens.

Adobe - Adobe Camera Raw and DNG Converter : For Windows : Adobe DNG Converter 9.10.1

Then in Filter>Lens Correction, select the last Samsung on the Camera Make list and under Lens Profiles you should see the10 mm 2,8 listed and below is the Rokinon 10mm f/2.8 listed under Lens Profiles.

The Rokinon and Samyang 10 mm f/2.8 are the same lens.

Thanks for the info!

I downloaded and installed as suggested.  There is a non-labeled 10mm f/2.8 listed when camera make is Samsung. 

However, the camera I am using is not a Samsung but a Nikon.  Lens Correction should be performing a correction for the image sensor based on camera make and model, if I am not mistaken, so selecting Samsung will not accurately correct the image.

I guess it's time I roll up my virtual sleeves and learn how to make corrections myself under the "custom" tab.

You might find a profile online, though a quick search didn't turn up one.

You can make your own profile using the Adobe Lens Profile Creator.

Looks like I'm making my own lens profiles.

Still doesn't answer the original question, but oh, well...

If you notice when it says no matching lens profile found everything up top is greyed out so nothing gets applied when clicking okay.

If you have raw files instead of jpeg, then in camera raw under Nikon that lens profile is listed

Thanks!  As stated in the original question, though, I am not using RAW but JPEG.

I guess the question is: why does it seem as if Camera and Lens Adjustments are applied in Lens Correction but are not actually?  The image certainly changes onscreen.

Why don't you take a raw photo with your camera and try the camera raw dialog and see if the provided

Rokinon 10mm f/2.8 lens profile works.

You can always save the file as a jpeg afterwards

I guess you'd have to convert the raw files to dngs before opening in cs6, but still camera raw files offer much more flexibility in processing options than jpegs do.

You already installed the dng converter, so you might as well test take a raw photo, convert to dng and see how it goes.

I'm going to mark this question as answered since there is apparently no answer to the question "why does it seem as if Camera and Lens Adjustments are applied in Lens Correction but are not actually applied?"

The reason as stated before is if there is there is the no matching Lens Profile Found message the adjustments are not applied when clicking Ok.

No lens profile detected with the generic 10 mm lens, so the settings are greyed out and not applied when clicking Ok

Switch the Camera Make to All or Nikon Corporation and then a profile is seemily detected although it's the wrong one, the top settings are not greyed out and the adjustment should show after clicking Ok.

You should at least try a test raw file converted to dng, open it in the camera raw dialog using File>Open and see if the right lens profile is detected under the Lens Correction tab.

Anyway, hopefully the lens profile you created with the adobe lens profile creator works.

Your camera should have the option to shoot both jpegs and camera raw files at the same time.
