What effect does closing the diaphragm have on image contrast and resolution?
GiorgioBOhikhuare
The optical characteristics of most lenses dictate that to obtain maximum optical quality, you ought to stop down at least 3 stops from maximum, as a general rule of thumb.

What is the effect of the diaphragm depression and the expansion of the rib cage inside the lungs?
When the diaphragm depresses and the rib cage expands, it increase the volume of the chest cavity. Actually, the rib cage doesn't really expand. The sternum (breastbone) move up and out slightly, moving the ribs slightly with it. This creates a pressure gradient where there is very low pressure in the lungs and higher pressure out. As a result of this gradient, air is almost sucked into the lungs, like air filling a vacuum space. As the diaphragm contracts and gravity pulls the ribs and sternum back down, the air is forced out of the lungs.
What is a quadraphasic cat scan?
A CT scan that is repeated a certain number of times in the same examination period is said to be multiphasic (bi-phasic, tri-phasic, quadra-phasic). The interest is in observing a change in a parameter as a function of time. The main reason is to show the effect of intravenous contrast on CT attenuation, say pre contrast, and at one, three and five minutes post injection. By observing increased CT attenuation ( aka enhancement), or lack thereof, and it's temporal and morphological characteristics, radiologists infer the probable diagnosis. The same can be said of pre and post contrast studies using other contrast agents or routes of administration (e.g. pre and post contrast fistulography).
How does magenta filters affect black and white photography?
Camera lens filters? They are known as FL series filters: FL-W, FL-D, FL-B used to correct the greenish color cast of the various types of fluorescent lighting. The problem would be most pronounced in color film, but would have the effect of reducing contrast between the shades of gray represented by certain colors in black & white photography. Enlarger filters? They are used to modify the contrast of variable contrast black & white print papers. They are also used in color printing to affect the color cast of the print.
What does an orange 02 filter do to photographs?
For black and white, it will pass more of it's complementary color (in the blue range) thereby darkening blue sky with less effect on white clouds, for instance. The net effect will be increased contrast between blues and reds. The white clouds appear to become more pronounced, but that is due to the darkening of the sky. Orange filters will do this more than a y2 yellow would, but not as much as a red.
What effect does closing the diaphragm have on image contrast?
According to the principles of microscopy, the image resolution will be nill if the diaphragm is closed not allowing any light through, so you will not be able to see anything.
What is the effect of diaphragm on resolution?
According to the principles of microscopy, the diapragm regulates the intesity of light on a subject as viewed through a microscope and will affect the resolution byÊmaking it sharp with theÊcorrect amount of light and fuzzy with to little light and too much light will totally wash the image out.
