Engineering is the way to go, but not mechanical......I'm a Mech. Eng, but if you are looking for money, chemical engineering and biomedical engineering is the way to go. I'm a number cruncher and I like to know how things work.
Honestly do something you'll love...at times engineering is difficult, fast paced, customer driven....makes me think otherwise every now and then.
But if you want to keep your svx running well.......get a good paying job
Not sure if photography can do that for you......unless money is not an issue.
