    Lightroom and iPad

    JBsiegel Community Member

      I have been experimenting with the iPad as a photo storage device.  I have a couple of questions regarding LR.

       

      First, my impression is that if you transfer DNG files into LR through the sync process, you lose all your LR edits.  In others words, the photo that is displayed is the original from out of the camera.  Is this correct?

       

      Second, if you transfer the file to the iPad through the sync process, is the file that is stored on the iPad the DNG file, or does the internal processing convert the file to something else, like a compressed jpeg?

       

      Anybody who has other experiences or observations with the iPad that are worth sharing, please do so.

       

      Thanks

          I don't use DNG but when I imported some photos to the iPad (mostly JPEGS and one

          Olympus RAW) it displayed them all fine but as you say, the RAW was displayed without any

          adjustments.

          But if I export photos from LR to a folder (say "iPad Photos") and then tell iTunes to sync with that photo, then all the shots have my LR edits.

          What I want to know is when they release the camera USB attachment and the card reader, when you import RAW directly from the camera, will the iPad display the unedited RAW file or the embedded JPEG.

          As far as how it is stored - that is anybody's guess because even with the iPad attached to computer, you can't access the file structure on the internal memory.

            Thanks.

             

            When you import them through your message, do you have photo albums, or is everything just stored under photos with no order and no ability to sequence?

             

            It would be nice if iPhoto had a setting that would turn off optimization

              Hi! Ho do you sync your Ipad using Lightroom? When I connect the Ipad to my computer, I do not see the Ipad as a source to load images from.

               

              Thanks

                Hi Vic,

                When I first plug in the iPad, iTunes opens up and does it's sync/backup stuff. When I open Lightroom and go to import, the iPad is there as a device. I don't do anything special. I assume that you have iTunes installed and that the iPad shows up properly? Or are you trying to see the iPad in Lightroom without it syncing in iTunes first? I am not sure if it will work that way.

                  Bear in mind that regardless of whether you are using RAW, DNG or Jpegs with LR the only place that your changes exist is within LR. The whole point of the LR way of working is that your edits are non-destructive, lR never changes the original file.

                   

                  If you transfer your original file to the iPad (or anywhere else for that matter) you are not really losing your LR edit's, they were never there in the first place. If you want to have a file containing your photograph that incorporates your LR changes then you need to 'export' from within LR and that create a new file, it's essentially a copy of the original with the changes and edits made in LR applied. That's what you should then sync to iPad. Obviously if you then make more changes in LR you have to export again.

                    In the case of DNG and JPEG files this is only true if you do NOT have the option 'Automatically write changes into XMP' checked AND if you never select 'Metadata->Save Metadata to File'.  In either case the original file is changed because the metadata is written to the file.  The original RAW files--those from the camera--can also be changed by LR if the option 'Write date or time changes into proprietary raw files.' is checked.  You are correct in that the actual image pixel data in the file(s) is never intentionally changed by LR.

                    Again, not strictly true in the case of DNG and JPEG files--if the 'edits' are saved to the file.  In this case the 'edits' are there in the form of metadata changes.  These 'edits' are read by ACR and LR but I don't know of any other software that is capable of applying the 'edits' to the displayed/printed/exported image. Unless the 'export' process strips the metadata changes then the 'edits' are still there.

                     

                    The iPad may strip the metadata from the file on import--I've never tested to see if that is the case.

                      Either iPad Photo displays the embedded JPEG or is programmed to apply some correction for the imported RAW images (from my Canon 40D) I see on my iPad are close to those I see on LR after my 'standard preliminary' adjustments for that camera/ISO are applied on import.

                       

                      In other words, they are not the dull, dimmed and flat images one would expect from an unprocessed RAW file.

                        Based on my experience with the Leica M9, the Canon and Nikon cameras must be automatically embedding a jpeg in the RAW file.  The M9 outputs DNG files.  The camera gives you the option to also output a jpeg file.  If you do not output a jpeg file, you get a horrible pixilated display on the iPad--not usable. Only if you set the camera to output a DNG and jpeg do you receive a usable (quite good) image on the iPad. 

                         

                        I am told that the Canon and Nikon cameras embed a jpeg file in all cases.  The Leica M9 also may be embedding a jpeg, if so a very basic one or one that the iPad can't read very well.  The other alternative is the the iPad can read the M9's DNG file, but not very well.

                         

                        I have heard that RAW files produced by some other cameras do not display properly on the iPad.

                         

                        The basic question about RAW files and the Camera Connection is as follows:  Have Canon and Nikon been able to add conversion/interpretation tools to the iPad, which is why the iPad displays their RAW files, or are Canon and Nikon embedding jpegs automatically.  Once the answer is known (which really is--what is happening in the iPad?), then we will know why some RAW files seem to display in the iPad with no effort and others require effort (make a separate jpeg).

                          Anyone know of a way to delete the photos from the iPad once the upload is complete?  Can be done in iPhoto but I don't see how to in LR.

                            I don't think LR can do that, you can always open the drive that is mounted go to the folder and delete the stuff. 

                             

                            But not 100% sure LR can't do it.

                              I have an Ipad2 and a PC running XP and LR3... I connect the ipad to the PC and I can see it as a device in Lightroom... however it says "No Photos Found"... however I have several thousand photos on the Ipad (DNG+JPEG) loaded using the camera connect kit.  I really need to get these off the Ipad so any help would be GREATLY appreciated.

                                If you connect your iPad to your computer using the standard USB wire, the iPad should show up in Lightroom and be available for importing.  Don't believe it will show if you are using the Camera Connection dongle.

                                  Note - I have been using the USB connection cord to connect the Ipad to the PC and the Ipad does show up as a device in Lightroom.  However, in LR when I click on the Ipad it says "No Photos Found".  This issue is not getting the Ipad to appear in LR but I know I have JPEG and DNG files on the Ipad so not sure how to get it to show the files to show up there....
