A few days later a box arrives containing packed of really tiny plastic bolts. It took me a couple of weeks to have a go and the results are getting there. See what you think:
1/2" stud, 3/4" Square Nut & 1" Washer
1" bolt, 1/2" nut & 3" washer
5" bolt, 11/2" nut & 2" washer
All were taken with my Canon G12 and are shown here smaller than full size. To get an idea, this is the last photo straight from the camera with only a crop and touch of lightening up.
Not bad. I think that light matters as much as focus. The really tiny bolts are translucent making them harder to shoot.
Best of all, I get to keep the bolts for use on future projects. All I have to do is take pictures of many packets. Looking at them, I already have some ideas for their use.
