Cameras, cameras ...
I own several cameras: Canon's, one Nikon and so on, but my iPhone is the real workhorse in my shop.
I love the iPhone camera for three important reasons: (1) It's a snap to get my images from the iPhone onto the web, (2) I can get it in places that I would never be able to with my regular cameras and (3), it fits in my pocket. IMHO, the iPhone camera makes perfect picture-taking sense for photographing my work as I complete a project.
You would not even be able to focus a normal camera in some of the places I have put my iPhone. Case in point: A few years back I had to dissasemble my Delta DJ-20 jointer before moving back to sunny New Mexico from dreary Chicago. From experience, I know that when taking a power tool apart you had better have some good how-to-put-it-back-together instructions and nothing serves that purpose better than several good photos.
Here are a few to make my point.
When I took apart my DJ-20, I wanted to be sure that I put this spring back in correctly and this photo was just what I needed to do that. I was holding up the (heavy) infeed table with one hand and took this photo with the other. Since I could not see what the camera was seeing, all I could do was hope for the best. I would never have been able to do this with one of my cameras in the same time it took me to do with the iPhone.
