I found it by the accident when I wanted to show my 6 cm earing presenting important detail and show full presentation with a full depth of field.
For the presentation I used my super-sharp lens Canon 70-200 mm. I also used retro (reverse) setting converters which changed minimum focus distance from 1,4 meter into few centimeters. That way I could close up to the object and show it extremely detailed and sharp. Additionally the equipment I used (Novoflex EOS RETRO, image) allows me to use all lens settings (Av- aperture and focusing). That’s really helpful. Firs animation I made standard way setting earrings in the middle of the turntable but I wasn’t happy with the depth of field (which is very short with retro lens setting).
Presentation 1. Standard spinning animation:
Av/f=22 , Tv/t=1/8s, ISO=400, white background (aperture value is very high, shutter speed Tv must be extended, so the results weren’t satisfying for me) .
I switched the Photo Composer interior into black shiny (it gives fine results and artistic look). I use larger diameter of turntable where the object is turned placing it ca. 1/3 of ray from the turntable edge along the edge (see the scheme – as far from the axis more curved. I’m estimating % of the circle used by the object> I’m setting 30 degrees animation with 30 frames. On the monitor (in MODEPix application) I see how the object is entering the frame from the left to the right catching the proper depth of field. I deleted also first and the last (less important view) that’s why the animation has 28 frames.
Presentation 2. More interesting – sliding animation:
Av/f=16 , Tv/t=0,6s, ISO=400
I recommend this technique for all products, which are long but they are worth to be presented precisely – earrings, beads/charms bracelets, parts of necklaces and chains.
