Hello Dejan Thanks for picking up my posting :-) I will have a look at the other cameras, but my one differs to the others by generating automatically the dynamic reconfigure file. Which has of course also a down side, one have to compile the note twice :-| And still there are some bugs left like, a segmentation fault on closing the node And some to todo's it would be nice to have services for all parameters. I just fixed some buts, but please have a try now. Greetings
