There is an apparent overall "softening" of the image sharpness and a reduction in image contrast.
Where Multiply comes in extremely handy is in improving image contrast on moderately overexposed images. Take an image and duplicate it as a new layer on top of the original. Change the blending mode of the top copy to Multiply and see what happens.
It's not the same as overall "image contrast", which is basically related to the MTF at low spatial frequencies (say 1-10 lp/mm).
8 EX APO IF HSM lens features an apochromatic optical design and four elements composed of Special Low Dispersion (SLD) glass for high image contrast, resolution and color saturation.
Also, improvement of image contrast not only improves resolution, it helps realize a "uniform circuit pattern" in IC production lines.
The E-20 provides control over image contrast and sharpening. You can select one level above or below the standard contrast or sharpening settings, Olympus's recent consumer digital cameras offer a total of five levels of adjustment.
Many would argue it is essential: Concepts of highlight and shadow detail, image contrast, film and exposure latitude and tonal range are all best understood by studying the black-and-white image.
Non-image-forming light scattered by reflections within a lens or enlarger/camera interior which reduces image contrast and detail.
Flare can affect film by causing a lowering of image contrast.

The claimed benefit of this method include: little or no ghosting; excellent image contrast; sharp image detail; simple method implementation; and being easy for the accommodation of the eyes.

-Holding back - 1. Shortening the development time given to film to help reduce image contrast. 2. Method of decreasing exposure given to selective areas of the print. Also referred to as dodging.
A portion of a digital capture is shown here with red arrows pointing to an out-of-focus scratch on the glass filter covering the sensor. The image contrast has been enhanced to make the scratch more visible.
The big win with Lab is that color saturation may be altered without changing the overall image contrast or brightness. When making this move be sure to keep the curves centered to avoid a color cast.
Lens coating
Transparent coated on lens elements that helps reduce reflections and flare to improve image contrast.

The point of this second conversion is to lighten the shadows so that we can get more detail in the shadows and reduce the image contrast. For this purpose, the Exposure control is adjusted to increase the brightness of the image.

The result is a dramatic increase in image contrast and actual light transmission and a corresponding reduction in flare caused by internal reflections.
Black and white points and image contrast were also adjusted to bring out the colour in the sky and sand while also bringing back the heaviness of the overbearing sky.
Under development
A reduction in the degree of development. It is usually caused by shortened development time or a decrease in the temperature of the solution. It results in a loss of density and a reduction in image contrast.
So if you are shooting mid-day, the light is going to look uninteresting. The best time to shoot a landscape would be early or late, when the light is low, and there are nice shadows to give the image contrast.
on the film or digital frame, often taking the shape of the aperture, generally caused from shooting towards the light source. The use of uncoated filters makes a lens more prone to flare; often results in an overall reduction of image contrast.
the shape of the aperture, generally caused by shooting towards the light source. The source may appear in the image as a reflection from the interior of the camera or from the lens. Flare often results in an overall reduction of image contrast.
and look at work prints, circling problem areas with a grease pencil. A good B&W printer should be able to make archival prints on fiber-base paper with selenium toning. The selenium toning deepens the blacks and thus increases the image contrast.
or you can tune white balance with a color wheel tool. The RAW dynamic range tool is basically a levels tool that allows you to set white and black point. There is no mid point or gamma setting with this tool. The tone curve tool sets image contrast.
