SHADOW DETAIL - Detail that is visible in an image's darker areas.
SHARPNESS - An image's degree of clarity in terms of focus and contrast.
SHEET FILM - Piece of film sized for one exposure in a view camera.

subtle features in the darker part of an image.
shadow dot
the smallest dots in a halftone negative, or the coarsest or largest in the positive or print.

Shadow Detail
Extremely dark areas (either in actual shadows or in unlit and underlit parts of the scene) in which some texture or detail has been captured. Tip: Careful Exposure readings, a Good Eye, and experience help with such details.

Shadow detail recovery in 12-bit versus 14-bit
One of the first things I found was just how remarkably good the camera did in both 12-bit and 14-bit.

5) Shadow detail lost; reexpose
Start With A Good Exposure
A primary concern during exposure is ensuring that exposure provides adequate information in deep shadow detail. Digital cameras respond to light differently than human eyes.

Lost Shadow Detail: Lost shadow detail results in blocked up areas that reveal little or no subject information. If the RAW capture does have some pixel detail embedded, bringing it out with software results in a file that’s noisy.

Expand shadow detail - drag highlight bar to the left
The histogram display shows a graph of image detail. Most likely, you wll see most of the action towards the shadow (left) end of the scale.

Note the shadow detail, in particular on the first example (bushes in lower left still has detail). The colours are clear and natural. This really is a fine film! I always keep a few rolls in the bag.

Unfortunately, shadow detail is lost, instead of gained with these filters, so they don't really live up to expectations. In fact, it's just like shooting through a dirty window.

'Luminosity' boosts shadow details and overall image brightness. I usually like to crank this up a little to see what's hiding in the shadows. 'Black Point' and 'White Point' set the high and low clipping levels in the image.

By the numbers: the shadow details meter at 1/30th @ ƒ8. To place them at the correct tone, the adjusted exposure would be two stops less, or 1/125th @ ƒ8. Just takes a little practice.

A silhouette effect (no shadow detail) of a back-lighted scene is produced by closing down one f/stop from the basic exposure. If shadow detail is desired, an increase of four times (two f/stops) from the basic exposure is required.

Hard light tends to lack shadow detail. As can be seen in Figure 7, it is very hard to see any detail in the shadow areas under this hard light.

Shadow detail can be recovered; blown highlights (the pure white areas in an overexposed photo) can never be recovered, as there is nothing there to recover.

Exposing your image in this fashion may cause you to lose a little shadow detail. However, this is usually a better approach than burning out all the detail in your brightest areas.

Digital and transparency are relatively good at retaining shadow detail, but highlights become clipped and burned out.

Photograph of marine life to demonstrate image manipulation in Photoshop Even though this photo is slightly underexposed, there is no noise in the shadow detail whether processed via Adobe’s Photoshop CS or Phase One’s Capture One.

If you see a histogram hit the wall to the left, you've underexposed and are missing shadow detail. If you see a histogram hit the wall to the right, you've overexposed and are missing highlight detail.

Depending on your camera and exposure settings its possible to recover a half stop or more highlight detail and a stop or so of shadow detail during raw conversion.

This tells me, that even the overexposed images contain some relatively dark areas, and that the tools do their best to enhance the shadow detail.

If you look closely at the shadow detail you can see that it is also creating darkness on his legs and a very ugly shadowing on the tops of the trees in the background.

The loss or either highlight or shadow details when tonal information is driven to pure white or black. For example, over exposure can produce clipping by driving highlights that should contain detail to pure white.

The exposure for Zone III is important, because if the exposure is insufficient, the image may not have satisfactory shadow detail. If the shadow detail is not recorded at the time of exposure, nothing can be done to add it later.

Of course there is a cost - loss of contrast in the highlights, which had to be compressed to make room for the shadow detail. Compare the second histogram to the first.

Make a second exposure to capture the best shadow detail. Then combine the two exposures in Photoshop as separate Layers. Using the Eraser tool remove poorly exposed areas to reveal detail and take advantage of the best parts of each Layer/exposure.

It is desirable to maintain shadow detail but there is a risk of decreasing overall contrast if one lightens the shadow too much in an attempt to expose detail.

Part of the reason is because the former have larger pixels on their sensors and that means a greater ability to record both highlight and shadow detail, without "clipping" either of those.

Term for lack of, or loss of, shadow detail in a photographic image, usually the result of underexposure or lower resolution (and less dynamic) imaging sensor. Can sometimes be partially corrected in Photoshop or similar photo editing applications.

Although the detail will be present in the negative special printing techniques will be required to render it correctly.
Under Exposure. Loss of shadow detail.

It reduces contrast and shadow detail.
F number: Numbers on the lens which is equivalent to the focal length divided by the diameter of the aperture.

HDR processing is a solution for the inability that a digital camera tends to have in capturing a single digital image that contains the full tonal detail range-from extremely bright, to very dark shadow detail.

Black is added to improve rendition of shadow detail. CMYK is commonly used for printing (both on press and with your inkjet or laser color printer). A few image editors, including Photoshop, can work with images using the CMYK model.

In the Develop module, which is the RAW image editor, on the left side of the application, you have all of the expected editing parameters available, such as white balance, exposure, highlight recovery, shadow detail, ...

It was the dramatic lighting and feeling of her isolation that caught my eye. Multi-pattern metering would have provided me shadow detail of the background.

how "forgiving" a film is to exposure error or deliberate under and over exposure. Also applied to the range of brightness, including shadow detail, ...

High ISO Speed Noise Reduction accesses four different degrees of noise reduction. You may wish to adjust this setting depending on the shooting situation and how much shadow detail noise you are willing to live with.

Underexposure occurs when the image sensor (or film frame) did not receive enough exposure time from the light source, such that the subject doesn't register effectively and is usually surrounded in shadows with limited shadow detail.

both shadow and highlighted objects (e.g., dark objects on a back-lit background), it is always a problem to capture both shadow and highlight details. Adjusting the camera settings to capture highlight details will result in losing shadow details ...

It lets him, if necessary, produce high dynamic-range (HDR) composites in the editing stage. As a result, his best photos always show plenty of highlight and shadow detail, even with high-contrast scenes. As habits go, it's a keeper.

watch out for lost shadow detail, or blown out highlights in 1 color spectrum.
Use spot focus. If your camera has the ability to move the focus point with the cursors, move the focus point over the area of the subject that you want in focus (e.g.

Specialist films, such as Fuji Velvia, are said to have a range of around 3.7D, so the scanner needs to have at least the same dynamic range to ensure every bit of highlight and shadow detail is captured in one scan. Also see "High Dynamic Range" ...

When metering for the highlights, the darker tones will be underexposed and lose their shadow detail, while if metering for the shadows, lighter tones will be overexposed and become completely white without any detail.

At a wedding, it's more important to capture the detail in the bride's white dress than to preserve shadow detail of the groom's black tuxedo, so you can choose to expose for the highlights, and not worry about the shadows being too dark.
