Sharpness graph
This displays a value known as MTF50, which is considered to correlate well with perceived sharpness. The y-axis is in line pairs per picture height, and the x-axis represents the distance from the image centre along the diagonal.

Sharpness Isn't Everything
Shallow depth of field can focus attention on a foreground subject by making the background less sharp.
"Sharpness is defined as the differentiation between one edge and how fast it transitions from one object to another," Haftel notes, "It's the same way that the human visual system works.
One of the qualities photographers most want to improve in their photographs is image sharpness. I think subject matter, composition, and lighting are equally or important, but let's address image sharpness since so many people ask about it.
Image Sharpness The outer edges of a lens are least likely to produce a well-defined or aberration-free image; therefore, proper use of the diaphragm, aperture, ...
Sharpness: Readings at 10 to 40 (or higher) lp/mm represent the sharpness-ability of a lens. Readings taken at 40 lp/mm indicate how good a lens can transmit very fine structures (e.g. hairs).
Sharpness
Reflected Light is the light that is being reflected off of an object, and represents a softer and different level of intensity than the light that is hitting a subject.

Sharpness. Sharpness is exactly what it seems to be, a control that allows you to increase or decrease sharpness in specific areas based on the gradient.
Sharpness - The clarity of detail in a photo.
Shutter speed - The camera's shutter speed is a measurement of how long its shutter remains open as the picture is taken. The slower the shutter speed, the longer the exposure time.
Sharpness - The clarity of detail in a photo.
Shutter - The device in the camera that opens and closes to let light from the scene strike the image sensor and expose the image.
Sharpness
A term used to describe the ability of a lens to render fine detail clearly; dependent on the contrast and resolution of a lens and varies with the f/stop; in general, a lens is sharpest at the middle apertures.

I've mentioned it a couple times before so let me explain aperture control and how it relates to making your product look good.
Sharpness of image is one of the most important facets of insect photography. We've all seen images of flies and other insects where the minute hairs on the body are visible. Without this effect, the whole impact of the image will be lost.

2. Sharpness in depth. This refers to the depth of field. Even if your primary subject is in crisp focus, shallow depth of field from a wide aperture may give the psychological impression of an out-of-focus photo.

image sharpness : For sharp images, use your cable release, the self-timer and a tripod.
shutter speed : Take several photographs of your subject while changing shutter speeds and f-stops.
Lack of Sharpness or Contrast Any fog, dust and other impurities will make objects further away appear somewhat hazy and lacking in contrast.
Picture sharpness also varies with f-number. The optimal f-stop varies with the lens characteristics. For modern standard lenses having 6 or 7 elements, the sharpest image is often obtained around f/5.
When judging sharpness in your pictures, use a quality 8X loupe or reverse a 50mm lens to view images. You can't tell much by projecting your slides. Follow the above steps and I'll guarantee, you will see great improvements in your photography.
Boost ISO for Sharpness
Reduce shake, increase depth of field
Some compact digital cameras set a higher ISO automatically as part of their anti-shake program, but many do not.
Definition, Sharpness
The perception of a well-defined, sharp image depends on a complex combination of factors some of which are: Focus, Depth of Field, Contrast, and maximum potential detail inherent in the recording media or emulsion.
Masking the Unsharpness
This is a funny way of saying sharpening. They have their reasons, those technical folks at Adobe. For now, though, we will just concern ourselves with the subtle use of their awesome tool and stop fussing over semantics.

shutter - The mechanism that opens and closes to make an exposure.
shutter curtain - Most focal plane shutters are composed of two curtains; a front and rear curtain.

Images with great depth of field have a large zone of sharpness, so that everything from just a few feet in front of the camera to infinity will be sharp.
These can affect colour, sharpness and shape.

There is a break-even point at which the disadvantage of the diffraction of the light captured is still compensated by the advantage of extra sharpness due to greater depth of field.
The last two factors that impact the range of sharpness both deal with distance. The closer you get to your subject, the more the background and foreground fall out of focus.

An indication of the sharpness of images on a printout or the display screen. It is based on the number and density of the pixels used. The more pixels used in an image, the more detail can be seen and the higher the image's resolution. 3.
How to use the camera aperture to influence sharpness
When you open your eyes first thing in the morning you are flooded with light and that makes seeing difficult. It is the same for the camera - when flooded with light things become blurry.
As a photographic property, sharpness has been given new meaning by digital imaging software. Programs such as Adobe Photoshop offer an extraordinary degree of control -- after the fact -- over the apparent sharpness of an image.
Aperture is a way to control light volume, but it also plays a critical part in the depiction of sharpness through the picture space, or the visual relationship of near-to-far subjects—what is known as depth of field.
