I have always found Industrial Photography interesting. It can be boring at times, but, as an engineer, there's always something to see. As an engineer (now retired), I did photography as a part of my job. Mainly, they found I knew how to do it and so, there I was. At a Ford plane, it was maintenance training films. Used a 16 mm Bell & Howell, and did all the editing. At White Motors, It was photographs for owners and maintaince manuals. At Mechanical Products, it was for trade shows. etc., etc. It was a fun part of the job, and I always enjoyed it.
