However, without a sharp subject-matter distinction of the classes, interpretation of results will be hard and may be also difficult to defend.
Now, like all pocket cameras, the S90 has a tough time creating that sharp-subject, blurred-background effect that's such a hallmark of professional S.L.R. photography.
The Canon, Fujifilm, Minolta, Samsung and Toshiba cameras, for example, offer what's called aperture-priority mode (for sharp portrait subjects with blurry backgrounds) and shutter-priority mode (to freeze sports action or blur babbling brooks).
The microsupport effect at sharp notches subjected to high-cycle fatigue can be described according to Neuber by averaging the maximum notch stress in a small material volume (microsupport length ρ*) at the notch root (radius ρ).
"We were fascinated" by how sharp the subjects' sense of smell became, says Jay Gottfried, an olfactory neurologist on Li's team.
Reconstruction algorithms were B70f (very sharp) for 54 subjects, B50f (sharp) for eight subjects, B31f for three subjects, and B40f for 23 subjects (smooth); the algorithm was not reported for 12 subjects.
A new app, named Nokia Smart Cam, also adds more gimmicky shooting modes including Motion Focus which blurs the background while keeping the foreground subject sharp, conveying a sense of action.
By positioning dozens of cameras at different viewpoints and processing the resulting data they were able to create a shallow-focus effect that left the desired subject sharp but obstructing objects so blurred that they appeared transparent.
In the description of his supercut compilation, Paul Thomas Anderson's Extreme Close Ups, filmmaker Jacob T. Swinney explains, "A PTA extreme close-up usually features a very shallow depth of field, keeping just a tiny portion of the subject sharp while the rest gradually falls out of focus.
