    Sigma fisheye defish in LR

    nickpearse

      I want to use lightroom to defish my images taken with my Sigma 10mm f2.8 EX DC for Nikon but can only do so if i shoot in RAW as there is no lens profile for images shot in Jpeg with this lens. Should i not want to shoot in Raw would it be ok to shoot jpeg and just use a very similar lens profile to correct my fisheye...does anyone know the best one?

          You can do that for sure. The correction will work best with raws but there is nothing wrong with trying to do it with jpegs. I couldn't find a profile for jpegs for that lens but it is fairly trivial to make a profile yourself. You do that with lens profile creator available here:

          Adobe - Adobe Lens Profile Creator : For Macintosh : Adobe Lens Profile Creator 1.0.4

          Adobe - Adobe Lens Profile Creator : For Windows

            Thats great thanks for the response.

             

            I shall try that later

             

            Do you know if there are already an lens profiles for fisheyes that will do just as good a job?

             

            Cheers

              You can try a profile for another fisheye like the Nikon 10,5 mm one. I don't know whether any of those will work well for this lens.

                You can copy and rename the existing RAW profile and convert it to a non-RAW ... at your own risk with no guarantee for its performance.

                Here's a guide: Better Family Photos: Lightroom - Creating a JPEG Lens Correction Profile

                  Hi,

                   

                  Thanks for that info, thats very interesting.

                   

                  I will have to try that out!

                   

                  Not sure if it's that easy why LR would'nt have done it in the first place.

                   

                  Cheers Anyway

                    The RAW and JPG do not have to be identical in a way that the same profile can perfectly correct both. The camera firmware creates the JPG from the internal RAW data and may already correct some parameters.

                    For a perfect operation, the profile needs to be created for both formats separately.

                    However, since the RAW profile for your lens is available, I'd give it a try. It's quickly done and the best you can get without generating a completely new profile.

                      Since this is a non-OEM lens (Sigma vs Nikon) no in-camera corrections should be applied. You can convert the currently installed Sigma 10mm F2.8 EX DC FISHEYE HSM raw lens profile as outlined at the link F. McLion provided.

                       

                      BTW- We had this same discussion a few months ago: How can i add the Sigma 10mm 2.8 Fisheye lens profile from the camera profile in windows to lightroom 5?

                       

                      If you're having trouble converting and installing the existing raw profile for this lens just tell us. We'll also need top know what version of LR you are using (1, 2, 3, 4, 5, 6, CC 2015). The location of lens profiles changed in LR 4.3 and later.

                          Hi,

                           

                          Thanks for your response.

                           

                          I am using LR 5. Are the location of the lens profiles still in the same place as you listed in the article you posted?

                            The Adobe installed lens profiles in LR4.3 and later versions can be found here:

                             

                            Mac

                            Applications/Adobe Photoshop Lightroom X/Right-click Show Package Contents/Resources/Lens Profiles

                             

                            Win

                            X:\Program Files\Adobe\Adobe Photoshop Lightroom X\Resources\LensProfiles\

                             

                            You need to open the current RAW profile SIGMA (Sigma_10mm_F2.8_EX_DC_FISHEYE ) - RAW.lcp in a text editor such as Windows Notepad or Mac TextEdit (change Format> Make plain text). Find ALL instances  of:

                             

                            stCamera:CameraRawProfile="True"

                             

                            and Replace with:

                             

                            stCamera:CameraRawProfile="False"

                             

                            Do NOT Save the modified file to the same location. Rename the file by changing - RAW to - JPEG and save the file to the below "user" location:

                             

                            Mac

                            Macintosh HD / Users / [your username] / Library / Application Support / Adobe / CameraRaw / LensProfiles /

                             

                            Windows

                            C: \ Users \ [your username] \ AppData \ Roaming \ Adobe \ CameraRaw \ CameraProfiles \

                             

                            Close and reopen LR to load the new lens profile.

                              I'm not sure, I don't have a LR5 installation around. On my CC 2015 it's:

                              C:\Program Files\Adobe\Adobe Lightroom\Resources\LensProfiles\1.0\Sigma\Nikon\NIKON CORPORATION (Sigma_10mm_F2.8_EX_DC_FISHEYE ) - RAW.lcp

                              that I would copy and rename to:

                              C:\Program Files\Adobe\Adobe Lightroom\Resources\LensProfiles\1.0\Sigma\Nikon\NIKON CORPORATION (Sigma_10mm_F2.8_EX_DC_FISHEYE ).lcp

                              and then modify as mentioned.

                                I left out the \1.0 folder name...that's where they are located in LR5 as well: C:\Program Files\Adobe\Adobe Lightroom\Resources\LensProfiles\1.0

                                That will not work. LR only recognizes and uses the program installed profiles at that folder location.

                                 

                                http://www.lightroomqueen.com/articles-page/lightroom-5-default-locations/

                                 

                                Your custom Camera Raw & Lens Profiles should be installed to the User folders…

                                Lightroom 5 no longer uses the shared ProgramData (Windows) / Application Support (Mac) folders for Camera or Lens Profiles. Instead, it stores the built-in profiles with its program files.

                                 

                                When you create camera or lens profiles, they must be stored in the user locations listed below. If you previously stored custom profiles in other locations, you’ll need to move them to these user folders, otherwise Lightroom won’t be able to find them.

                                 

                                Windows—C: \ Users \ [your username] \ AppData \ Roaming \ Adobe \ CameraRaw \ CameraProfiles \

                                Mac—Macintosh HD / Users / [your username] / Library / Application Support / Adobe / CameraRaw / CameraProfiles /

                                 

                                For the lens profiles, substitute the LensProfiles folder for the CameraProfiles folder.

                                  I think im sort of there but frustratingly it still doesnt appear in lightroom.

                                   

                                  The new JPEG format; NIKON CORPORATION (Sigma_10mm_F2.8_EX_DC_FISHEYE ).lcp.txt

                                  I've changed all th ''True'' to ''False'' in notepad but still it won't show up in LR.

                                      One minor detail. The text editor adds the plain text file extension .txt when you save the edited lens profile. Rename the file without .txt and it should show up:

                                          I don't think there are many disadvantages except for that it is highly

                                          likely that the vignetting correction will be incorrect if you use the raw

                                          profile on jpegs, so you might have to play with the amount slider on that
