Film speed and lighting...
I use a couple of my small portable lamps that have flexible arms, kind of like this one:
I think they have 60 watt incandescent bulbs in them. One is usually enough for auto focus to kick in and for the camera to stay at ISO 100 or 200 range. (I also use them when working on the layout when the normal lights are not enough. Yes, I could add more lights to the room but I like the color, look and shadows I get with the current lighting.)
The 'International Standards Organization (ISO)' I am talking about means ISO ratings for film speeds. 100 and 200 are normally for indoors with flash or outdoors with good daylight. 400 is faster film and used sometimes for fast action or near dusk. There are higher speeds but I rarely use them and when I do, it is for artistic effects.
What I have been doing for the staged engine shots is put the engine on my test track on my workbench. I have a three foot long, double florescent strip light hanging about 2 feet over the workbench. If that is not enough or the portable lamps are not working, I also have a portable halogen flood lamp on a big clip I got from Home Depot:
but it feels more like I am taking x-rays with it than pictures
