I continue to use my tilt-shift adapter for DSLR, and now I explore the limits of the system. Below is the watch, at a very narrow angle, shoot by using Rodenstock Rodagon APO 80mm F4 lens at aperture setto F16.
The lighting schema is simple: two narrow soft boxes on top, each highlighted top and the bottom part of the watch. There should not be direct reflection form a watch’s glass, as it immediately become dull and low contrast.
Front lest was tilted to about 25-30 degrees, the maximum I can get without lens projection circle going out from a sensor.
The focus plane was tilted accordingly (see the schema), produced image was exceptionally sharp across a whole watch’s dial. Something which you can’t never get without tilt-shift adapter or focus bracketing.
There are few trade-offs from such setup:
- Little increase of chromatic aberration and diffraction, increasing with the tilt angle.
- Manual operations focusing (aperture is manual as well) only available, done by moving the lens plate on and off from a camera. Which require precise gearing on the large format camera. (Cambo Master PC I use, is really good, very precise movements).
- Weight. The whole thing weights a lot, heavy weight head and tripod is a must.
Overall the system works very well for me, despite I never used Large Format cameras before.
