The documentation for Lens Profile Creator refers to "Adobe Camera Model Lens Design Data Conversion" which sets forth the .txt file format for batching a variety of profiles (e.g. for zoom lenses, disparate apertures, etc.) into a single profile file. This .txt file is required when selecting "File->Batch Convert Lens Design Data" in the application.
I cannot find this document anywhere.
Does anyone know where it can be downloaded?
