5.2 Exposure Area
You can correct the exposure with Nero PhotoSnap. For this purpose there is a histogram
and gradation correction curve available in the Color/Exposure area. The following tabs are
available:
Histogram
Correction
This defines the brightness range of the histogram using two lines.
On the left are the light pixels, on the right the dark pixels.
The histogram is recorded in the background.
Gradation
curves
Defines the distribution of the brightness values using a curve. On
the X axis are the hue values of the original from light to dark, on the
X axis the tone values after the correction from light to dark. A
straight curve with a 45° angle means that the original values remain
unchanged.
The histogram is recorded in the background.
The histogram graphically shows the brightness distribution of the image pixels. On the X
axis are the hue values from 0 (light) to 255 (dark), on the Y axis the number of pixels.
Image Effects
Page 18
5.2.1 Correct Brightness Range
With Nero PhotoSnap you can correct the exposure of the image by adjusting the brightness
range of the histogram. The histogram graphically shows the brightness distribution of the
image pixels. On the X axis are the hue values from 0 (light) to 255 (dark), on the Y axis the
number of pixels.
The following prerequisite must be met:
The Exposure area is displayed.
To correct the brightness range, proceed as follows:
1. Click the Histogram correction tab.
Æ The Histogram correction tab is displayed.
Fig. 3: Exposure area, Histogram correction tab -- this image is underexposed
2. To automatically adjust the brightness range, click the Adjust automatically button.

Æ The end of the brightness range is defined.
4. Click the Apply button.
Î You have adjusted the exposure. The histogram of the image being edited now
stretches across the entire brightness range.
A well-exposed image has a histogram with different elevations spread from left to right. In
contrast, an image which is underexposed or overexposed has no elevations or only very
flat elevations in the left and/or right areas. To correct such an image, you can move the
lines accordingly until they achieve the elevations or you can have it done automatically.
The hue values then cover the entire brightness range, and the exposure is corrected.
Image Effects
Page 19
5.2.2 Correct Gradation Curve
You can correct the exposure of the image with Nero PhotoSnap. The gradation curve
defines the distribution of the brightness values. On the X axis are the hue values of the
original from light to dark, on the X axis the hue values after the correction from light to dark.
A straight curve with a 45° angle means that the original values remain unchanged.
The following prerequisite must be met:
The Exposure area is displayed.
To correct the gradation curve, proceed as follows:
1. Click the Gradation curves tab.
Æ The Gradation curves tab is displayed.
2. To prevent a distortion of the brightness ranges that should not be changed, click the curve.

5.4 Resolution Area
With Nero PhotoSnap you can change the resolution, the size and the print size of the
image.
Fig. 6: Resolution area
The following areas are available in the Resolution area:
Resize Mode Selects a method for changing the size of the image.
Pixel Dimension Defines the size of the image in pixels.
Document
resolution Defines the resolution of the image in pixels per cm or inch.
Document Print
Size Defines the print size of the image in cm or inches.
In the Resize mode area the following selection options are available:
Constrain
proportions
check box Retains the proportions of the image.
Combo box entry
Do not resample
image
Changes the pixel size of the image; the image is not re-
calculated if there is a major change.
Combo box entry
Nearest
neighbor
Re-calculates the image if there is size change by doubling or
omitting pixels.
This method is the fastest and easiest and is especially suited to
illustrations with few colors. Contrasts and edges are retained.
Not well suited for photography.
Combo box entry
Bilinear
Re-calculates the image if there is size change by taking into
account the upper and lower pixels for the recalculation.
This method is fast and especially suitable for drawings and
illustrations.
Combo box entry If there is a size change, the image is re-calculated by taking into
Image Effects
Page 23
Bilinear (Bartlett) account the surrounding pixels in different parts.
Though more exact for image size reductions than the simple
bilinear method, it is slower. This method produces the best
results for drawings and illustrations.
Combo box entry
Bicubic
If there is a size change, the image is recalculated by taking into
account all adjacent pixels during the recalculation.
This method is particularly suited for realistic photos. The edges
and lines are retained relatively well. However the method may
produce artefacts on sharp edges and is therefore not well suited
for drawings.
Combo box entry
Lanczos
If there is a size change, this recalculates the image by taking
into account the surrounding pixels in a defined ratio to the
recalculation.
This method is qualitatively the best and thus requires the most
time to calculate. It is especially well suited for detailed half-tone
photos. However the method may produce artefacts on sharp
edges and is therefore not well suited for drawings.
If the default Apply and Cancel buttons are not visible, enlarge the program window using
the window corners.
5.5 Noise Area
With Nero PhotoSnap you can increase or reduce the noise of the image. Noise occurs in
digital photos if the ISO sensitivity is high when taking photos. Disturbance signals,
unwanted pixels or artefacts may appear.
Fig. 7: Noise area
The following configuration options are available in the Noise area:
Remove Noise tab
Smoothness Defines the degree of general noise reduction.
Noise levels Defines the degree of noise reduction of the primary colors red,
Image Effects
Page 24
green and blue.
Auto profile Automatically reduces noise. The regulators are set to an optimal
value.
Add Noise tab
Noise levels Defines the level of general noise increase.
5.6 Sharpen Area
Nero PhotoSnap lets you sharpen or blur the image. The sharp effect is achieved with the
Unsharp masking filter, the unsharp or blur effect with Gaussian blur. The impression of
sharpness results from images with a great many tone value changes, i.e. from the contrast
between two areas. The more angular and different in tone value these areas are, the
sharper the transition appears.
Fig. 8: Sharpen area
The following entry options are available in the Sharpen area:
Unsharp masking
Size Defines how many pixels should be included in the sharpening
calculation.
Amount Defines the degree of contrast removal.
Threshold Defines from which edge contrast sharpening should occur.
Gaussian blur tab
Size Defines how many pixels in an area should be included in the
unsharp calculation.
There is no regulator mixing for sharpening that applies to all images. The optimal regulator
mixing must be determined by trial and error.
Image Effects
Page 25
5.7 Red Eye Removal
Nero PhotoSnap lets you remove red eye. Red eye in photos usually occurs when a person
or animal is photographed with a flash in dark surroundings. The flash or light is reflected by
the retina and appears red in photos. The effect is even greater if the pupil is opened wide.
The following prerequisite must be met:
The Red eye removal area is displayed.
To remove red eye with Nero PhotoSnap proceed as follows:
1. Click the image, hold down the mouse button, and draw a circle or ellipse around the pupil.
Æ The area is marked and the red pupil is colored black.

7.1 Image Format Settings Window
For TIFF, JPG and PNG image formats you have certain compression and saving options
available in Nero PhotoSnap. You can open the relevant window via Save > Settings.
Fig. 10: TIFF settings window
The following option fields are available in the Compression area of the TIFF settings
window for TIFF images:
None No compression.
LZW
Performs non-lossy fast compression using the Lempel, Ziv and
Welch method. The file size can be reduced by up to 50%. The
loading time in editing programs can, however, be longer. This
method is particularly well suited for gray scale and color images.
JPEG Carries out a lossy JPG compression (quality loss). Using the
JPEG compression strength slide regulator you can define the
degree of compression.
Group 3 fax Performs a non-lossy compression by encoding isochromatic
pixels and saving the information separately. This method is used
by all fax devices and is well suited for black & white images.
Group 4 fax Performs a non-lossy compression by encoding isochromatic
pixels and saving the information separately. The method is well
suited for black & white images.
CCITT RLE
Carries out a non-lossy compression using Run Length Encoding.
Isochromatic pixels are encoded using counters. This method is
particularly suitable for black & white images or images with large
areas of the same color.

Glossary

12 Glossary
Resize
The resolution is a measure of the amount of visual information contained in a picture. The
number of pixels in a photograph determines the absolute resolution, while the number of
pixels per unit of length provides the relative resolution, normally expressed in dpi (dots per
inch).
Image noise
Like all semiconductors, CCD chips possess a certain ground noise, which makes itself felt
as a disturbing image noise. If the ISO number is increased from 100 to 400 when it is dark,
then boosting the signal will also increase the noise and this will make itself noticeable in the
image. Wherever it is feasible, a lower ISO number should be used in order to keep the
image noise as low as possible.
CCD chip
CCD stands for charge coupled device. A CCD is a light-sensitive sensor that can collect
and store light. The light-sensitive cells called "pixels" are located in a matrix on the element.
A charge is decoupled from each cell, proportional to the amount of light, and is then stored
for further processing.
dpi
Abbreviation of "dots per inch". DPI indicates the number of dots (i.e. pixels) per inch (1 inch
= 2.54 cm) that an output device supports.
EXIF
EXIF stands for Exchangeable Image File Format and is a standard of JEITA (Japan
Electronic and Information Technology Industries Association) for meta information in image
files. Information such as camera type, aperture, exposure time, distance to object and the
date when the photo was taken can be stored in the metadata. JPEG and TIFF graphic
formats are supported. Metadata is written to the header of the photo, i.e. before the actual
image information. This information can be read in the File information window with Nero
PhotoSnap and Nero PhotoSnap Viewer.
ISO number
For analog films, the light-sensitivity is quoted as an ISO number, where the coarseness of
the grains of film increase as the number does. Although the sensitivity of the CCD chip is
constant for digital cameras, a higher ISO number can be simulated - by increasing
sensitivity as a result of boosting the signal. One undesired effect of boosting the image
signal is increased image noise.
JPEG
An image format developed by the Joint Photographic Experts Group; an efficient but lossy
compression method.
Pixels
The term "pixel" is an invented word, a hybrid of "pix" (picture) and "el" (for element). A pixel
is an image element and the smallest unit of a digital graphic. Multiplying the number of
pixels per inch of the height and width of the image gives the total number of pixels; an
image of 800 x 600 pixels in size thus contains 480.00 pixels.

Progressive compression
Type of compression for JPEG images. When a progressively compressed JPEG image is
accessed in the Internet, it becomes visible in layers. The user first sees an unsharp image
which then becomes increasingly sharp.
RGB
In RGB mode, all the different colors are characterized by their red, green and blue
components. The color produced is the result of adding the three color components.
HSL
In HSL mode, the color is described on the basis of its Hue, Saturation and Lightness.
