What type of training will you be receiving? On machines in general? Mechanical or computer? A specific brand? You will have learned a valuable skill!
There's so many things one can do with the camera..QNS. I have one friend that takes pictures of fabric choices in black and white to see if she has the right values (of light and dark) in her selection. I'm lucky to get a picture taken, but it is very easy once you learn how and remember to!
