    Lightroom export will only open 25 images per external process

    Mike.Ke

      Hello,


      I use the Lightroom 4.1 export feature to export my HDR panorama images as 16 bit tiff in a temporary folder and after that to open the images automatically in PtGui Pro 9.1.x. The problem is if I export more than 25 images PtGui Pro starts one time for the first 25 images, then a second time for image #26 till 51, and so on. This happens during all my test with multiple image formats like 8 bit tiff with/without compression or with jpegs. It makes no difference whether the temporary folder is located on an SSD or a regular hard drive.

       

      Additional I tested LR4 Export to Hugin 2011.4.0 (32Bit) and Gimp 2.8 (64Bit) and the result is the same like with PtGui Pro: After the 25th image a new instance of the program started.

       

      Because of this behavior in different programs, I must assume that the fault must be with Lightroom. Is there any hardcoded limits by handover of pictures to external programs?

       

      Regards, Mike
