@digitalus / Peter, welcome!! I would be happy to help out. Just tag me with @ and my user name when you want to ask me a specific question in your thread. It is polite to start your own new thread to discuss it. There are others who are more experienced who might join in as well with helpful input and those who are in a similar learning position that would like to observe and learn or contribute.
This is Hibo’s thread about his LR4 and your photo didn’t finish uploading, so I’ve made a new thread for your discussion here.
