+==== Calibration manually ====
+The algorithm that selects the pictures in camera_calibration is not perfect, and it prefers to select blur images over sharp, also most of the times it doesn't use enough pictures. So here we explain how to use your own pictures to calibrate.
+  * Run image_view and take the pictures that you consider adequate for calibration using the left clicking.
+  cd /tmp/
+  rosrun image_view image_view image:=/gscam/image
+Images are store in the current directory.
+  * Run the calibration from disk images:
+  rosrun camera_calibration camera_calibrate_from_disk.py --size 8x6 --square 0.0247881 /tmp/frame00*
+  * This will print the parameters to screen. Replace them in one camera_calibration.txt example file. (look in gscam directory).
