Depth of Field: Bypassing the Limits Using a Tilt Lens
A tilt or tilt/shift lens allows angling the plane of focus to so that it is no longer parallel to the film/sensor. More to purpose, the tilt function lets the photographer skew the plane of focus through the subject matter as bet befits the sharpness goal.
An ordinary non-tilt-capable lens places the plane of focus at a fixed distance whereas a tilt lens angles the plane of focus at varying distance.
In a tilt lens, the angling of the plane of focus is achieved by mechanical adjustment; the photographer chooses a plane of focus that cuts through the subject matter at a varying distance. Arriving at the film/sensor, the subject is thus sharp even wide open, potentially from a few feet away to the far distance.

Diglloyd Making Sharp Images articulates years of best practices and how-to, painstakingly learned over a decade of camera and lens evaluation.
Save yourself those years of trial and error by jump-starting your photographic technical execution when making the image. The best lens or camera is handicapped if the photographer fails to master perfect shot discipline. High-resolution digital cameras are unforgiving of errors, at least if one wants the best possible results.
- Eases into photographic challenges with an introductory section.
- Covers aspects of digital sensor technology that relate to getting the best image quality.
- Technique section discusses every aspect of making a sharp image handheld or on a tripod.
- Depth of field and how to bypass depth of field limitations via focus stacking.
- Optical aberrations: what they are, what they look like, and what to do about them.
- MTF, field curvature, focus shift: insight into the limitations of lab tests and why imaging performance is far more complex than it appears.
- Optical aberrations: what they are, what they look like, and what to do about them.
- How to test a lens for a “bad sample”.
