Result: extremely high spatial resolution, far beyond the so-called "retina" point, even at close range — beyond even glossy magazine levels of sharpness, a dream for rendering type.
In other works that involve psycho-visual experiments, the number of original images considered is even lower, four images each printed on 15 different papers [28], or five images each with 15 different levels of sharpness [29].
While a little soft at f/1.4 this 50mm offers unbelievable levels of sharpness at f/2.8 and above.
Ideally, when you're finished, the blade should be roughly as sharp as a butter knife.[8] Lawnmower blades don't have to be razor-sharp — they spin fast enough to cut the grass without this level of sharpness.
At this level of sharpness individual pixels cannot be discerned by the human eye.
The central part of the algorithm is the "Λ-analysis" (see Fig. 3), which provides a quantitative evaluation of the level of sharpness of slopes and the level of quietness of wings.
However, the transmission map should have a similar level of sharpness to the color image for dehazing, which is impossible if the color image is not used in the transmission map refinement.
Since the refined transmission map is fully obtained from the hazy image, the resultant map contains the similar level of sharpness of the hazy image without yielding significant false color textures.
Overall and color liking were measured using a 9-point hedonic scale, and flavor, chewiness, level of sharpness measured using a 5-point just-about-right (JAR) scale (with 1 being not enough, 3 being just about right, and 5 being too much of the attribute).
However, if you're using digital (or are willing to use your film up a bit quicker), you can try taking several shots in succession and hopefully one will have a satisfying level of sharpness.
Following this, we solve the following specific problem: how do we compute the allowable variability in lead time for individual stages of the supply chain so that specified levels of delivery sharpness and delivery probability are achieved in a cost-effective way?
