5.2.1 Settings in the Lighting Region
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 Gravitation curves 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. 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 Y 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 picture pixels. On the X axis are the hue values from 0 (light) to 255 (dark), on the Y axis the number of pixels. See also: Main effects 13 Correcting the Lighting with the aid of the Histogram 31 Lighting with Gradation Curve 33

5.2.2 Color Balance

You can correct the color of the picture with Nero PhotoSnap and, for example, remove a color cast. Correction options in RGB and HSL modes are available for that purpose in the Color/Color balance area. You can perform the color balance with the RGB tab in RGB mode: colors are defined with combinations of the three primary colors red, green and blue. The color balance can be performed on the HSL tab in HSL mode: colors are defined by a combination of hue factors, saturation and lightness.

Color Balance, Tabs, RGB Area
The following input options are available on the RGB tab: Slider Red / Green / Blue Button Auto-remove color cast Regulates the amount of color. Slide the regulator to the right to increase the amount of color (up to 100%). Slide the regulator to the left to decrease the amount of color (to 0%). Automatically balances an existing color cast.

5.2.3 Resolution Settings Area
The resolution, size and font size of a picture can be changed in the resolution area.

Resolution Area

The following areas are available in the Resolution area: Area Resize Mode Check Box Constrain proportions Area Document resolution Area Document Print Size Area Document Print Size The following selection items are available in the Size-Change Mode selection list: No picture resampling Nearest Neighbor Changes the pixel size of the picture; the picture is not re-calculated if there is a major change. 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. Defines the print size of the picture in cm or inches. Defines the print size of the picture in cm or inches. Defines the resolution of the picture in pixels per cm or inch. Retains the proportions of the picture. Selects a method for changing the size of the picture.
Image effects Bilinear Re-calculates the picture 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. If there is a size change, the picture is re-calculated by taking into account the surrounding pixels in different parts. Though more exact for picture size reductions than the simple bilinear method, it is slower. This method produces the best results for drawings and illustrations. If there is a size change, the picture 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. If there is a size change, this recalculates the picture 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.

5.2.4 Noise Settings Area
In the Noise area it is possible to increment or decrease the picture noise. Noise occurs in digital photos if the ISO sensitivity is high when taking photos. Disturbance signals, unwanted pixels or artefacts may appear.

Noise Area

Image effects The following settings are available on the Noise tab: Slider Smoothness Area Noise levels Button Auto profile Defines the degree of noise reduction of the primary colors red, green and blue. Automatically reduces noise. The regulators are set to an optimal value. Defines the degree of general noise reduction.
The following slider is available on the +Noise tab: Noise levels See also: Main effects 13 Defines the degree of general noise reduction.
5.2.5 Sharpening Settings Area
In the Sharpen area the picture can be sharpened or softened. The sharp effect is achieved by the Mask Softening filter that wipes out unsharpness or softening effects with the Gaussian filter. The impression of sharpness in pictures is the result of as high as possible tone value change, meaning from the contrast between two surfaces. The more edgy and contrasting these surfaces are, the sharper the transition seems to be.

Sharpen Area

The following settings are available on the Mask Softening tab: Size Amount Defines how many pixels should be included in the sharpening calculation. Defines the degree of contrast removal.
Image effects Threshold Defines from which edge contrast sharpening should occur.
The following slider is available on the Gaussian Blurring tab: Size Defines how many pixels of an area should be included in the unsharpening calculation. There is no general regulator mixing for sharpening that applies to all picture. The optimal regulator mixing must be determined by trial and error. See also: Main effects 13
5.2.6 Rotate Settings Area
In the Rotate area you can rotate the picture or the picture content.

Rotate Area

Technical Information

10.1 System requirements
Nero PhotoSnap is installed along with the Nero Suite. Its system requirements are the same. You can find more detailed information on the system requirements under www.nero.com.

10.2 Key Combinations

The following key combinations for entering commands are available in Nero PhotoSnap and Nero PhotoSnap Viewer: [Ctrl+O] [Ctrl+P] [Ctrl+S] Ctrl + Z [ALT + F4] Number pad * Number pad / Number pad + Number pad Opens the file browser so that a picture can be selected for importing.

The Joint Photographic Experts Group-Format denotes a file standard for compression of pictures with resulting losses. Pictures compressed with JPEG carry the file extensions *.jpg or *.jpeg.

Lens Aperture

A lens aperture is an arrangement on the camera which regulates the amount of light falling onto the lens. It determines, on the one hand, the light intensity on the data carrier and, on the other hand, the color sharpness of the photo.

LZW Algorithm

The Lempel-Ziv-Welch algorithm uses a standard of loss-free data compression that was developed by Abraham Lempel, Jacob Ziv and Terry Welch.

Metadata

Metadata is particular additional information for data with the purpose of describing it better and for making it easier to find. Metadata contains information on the artist, album, track, running time, bit rate, resolution, and so on. As a result, it is possible to categorize files according to their type (audio, video or picture).

Picture Noise

The picture noise is an optical coarse graining which is disturbingly noticeable in a photo. As all semiconductors, a CCD sensor chip possesses a certain basic electronic noise that is triggered by signal superposition and interference frequencies.
A Portable Network Graphic designates a loss-free compression format for graphic files. It is the successor to the GIF (Graphic Interchange Format) and serves mainly for the standardized exchange of graphics on the Internet.
Red, Green, and Blue designate the combination of primary colors for a new color combination. 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 to white.

Run-length process

The run-length process designates an algorithm for loss-free graphic compression. In this process same-colored pixels are coded with the aid of counters. The method is mainly suitable for black-white pictures or pictures with large same-colored areas.
The Tagged Image File Format designates the container of a graphic format in which picture files can be saved. It is often used in the pre-print step as an exchange format.

4. Click on the 'Apply' button to conduct automatic adjustment. v

3.3.3 Exposure

The CCD chips used in digital cameras, record images by measuring the brightness of each pixel and depicting the brightness as a numerical value. Usually, values between 0 and 255 (i.e. 8 bit) are saved for each color component (red, green or blue). Where possible, the brightness in the subject being photographed should match the range that can be achieved by the sensor, so as to achieve optimum picture quality. When post editing a digital photograph it thus makes sense to check which brightness values the sensor can record. A so-called histogram is used to assist. The brightness values which can generally be achieved in the picture are displayed on the horizontal (X) axis, while the vertical (Y) axis shows the number of pixels with their respective brightness values. Graphically displayed, this provides a kind of "mountain range", which tells you at a glance whether the image is already of a good quality or whether it may need post editing. The histogram and its importance for post editing: a. The histogram contains a "mountain" on the left-hand side, whereas the righthand side does not display any upward deflection or is very flat. A picture like this is underexposed. In order to correct this digital photograph, the histogram must be (figuratively speaking) "stretched" to the right so as to cover the entire brightness range.

Nero PhotoSnap 23

b. The histogram has a "mountain" on the right but the left-hand side is relatively empty or very flat. This means that the picture is overexposed. The histogram needs to be moved to the left to correct it. c. The histogram has a "mountain" in the middle, though the histogram to the left and right of it is very flat. This means that your digital camera has not made full use of the CCD chip's available brightness range. Depending on the width of the "mountain" in the histogram, the picture may appear low in contrast to a greater or lesser extent. There are two possible causes: either the camera's automatic control mechanisms have not worked or the subject does not have a large brightness range (e.g. a foggy day in London or a black cat on a dark cushion). If the subject was the cause of the problem, an exposure correction would ruin the atmosphere of the picture and so the image should not be changed. When correcting the image, the histogram should be stretched in such a way that use is made use of the entire brightness range available. d. A mountainous landscape can be seen on the histogram, covering the entire range of the histogram from left to right. By all appearances, a picture like this is correctly exposed. Correction is probably not necessary. However, if you would still like to undertake an exposure correction by shifting the left and right-hand sides of the histogram, all the data outside the vertical border lines of the histogram will be lost. On the other hand, if a particular color area is to be brightened or made darker, this can be done with the aid of the gradation curves (by "bending" the curve up or down).
1. Start Nero PhotoSnap and open the desired photograph. 2. Click on the 'Exposure' effect to open the editing menu for this effect.

Nero PhotoSnap 24

3. To make an automatic histogram correction, click on the 'Autofix Histogram' button. The left and right brightness limits will be reduced and the enclosed area will 'slip' into the middle. As a result, the colors will become brighter.

Before

On the X-axis, the brightness values will be displayed, ranging from very dark (left) to very bright (right). The Y-axis shows the number of pixels with this brightness. In the preview you will see a comparison between the current picture and the picture as it would look if you used the effect.'

Nero PhotoSnap 25

If you would like to set other brightness limits, click with the mouse on a fringe region and shift the enclosed color area. 4. Click on the 'Apply' button once you are satisfied with the results of the correction. The tool menu will then be closed. On the 'Current' tab you will then see the altered image, while you will be able to see the stored image on the 'Saved' tab. In addition to (or instead of) a histogram correction, you can also alter the gradation curves. The gradation curve determines which input brightness value is to be represented by which output brightness value during the filtering process. On the X-axis however, the darkest pixels are on the left and the brightest on the right. The Y-axis displays the darkest pixels at the bottom and the brightest at the top. A straight line on the diagonals does not have any effect. A curve bending upwards makes the picture brighter if the curve bend downwards, the photograph will become darker. Special effects can be achieved by deliberately changing the shape of the curve. Particular areas can be made brighter, for instance. To do this, bend the desired brightness area up or down. Control points can be set out, to avoid changes in those brightness ranges that are not to be altered. Normally, significantly deformed curves have an unattractive effect on the picture and should be avoided. However, gentle manipulation of the gradation curve can be very useful. To do this, click on 'Gradation Curves' and shift the curve in the directions desired.

3.3.4 Color balance
If often occurs that images have a bluish or reddish tinge. This is because the camera saves the original chromaticity (hue). In particular, photographs taken in daylight with a great deal of blue sky frequently have a blue tinge. In contrast, pictures taken indoors, illuminated only by artificial lighting, usually have a reddish hue. Though the human brain is capable of compensating for these distortions, a camera is not. In earlier times (analog) photographers conducted color balance correction in the darkroom. Nowadays, you can make these corrections yourself, without any need for an outside darkroom. In fact, in some cases you may be obliged to make these changes yourself, depending on the type of camera you have. If you do not print your own pictures but use a print service, color balance correction will usually be performed at the print service itself. In this case it does not really make sense to spend too much time on adjusting the colors, as the print service will perform its own color balance correction in any case. However, should you wish to print them yourself or publish them on the Internet or use a print service that operates without any automatic picture correction when requested, then it is useful to conduct the color balance correction carefully.

1. Start Nero PhotoSnap and open the desired photograph. 2. Click on the 'Color balance' effect to open the editing menu for this effect. 3. Look for a neutral color on the photograph such as gray, in other words, a color without any red, green or blue components and use the click on the desired section. pipette to

Nero PhotoSnap 27

In the case of an automatic color repair, an attempt is made to eliminate any possible changes to the color on the basis of the color distribution in the picture. Unfortunately it is not always possible to do this automatically because the best color representation in a picture is a question of taste. If photographs are taken of a candle-lit party without using flash for instance, then the pictures will certainly appear to have a reddish tinge. However, should this reddish hue be removed or is it precisely this tone which provides the evening's atmosphere? Does a primarily blue underwater photograph have a bluish tinge or on the contrary, is this the very effect that is desired (and something that is perfectly normal for this type of picture)? In other words, you can now understand how perfect automatic color correction is unfeasible. Please remember this next time Nero PhotoSnap provides an autocorrection that does not appeal to you. The RGB component of the color will then be recalculated and the color will change.

Nero PhotoSnap 28

In the preview you will see a comparison between the current picture and the picture as it would look if you used the effect.
4. Click on the 'Apply' button once you are satisfied with the results of the correction. The tool menu will then be closed. On the 'Current' tab you will then see the altered image, while you will be able to see the stored image on the 'Saved' tab. In addition to (or instead of) an RBG correction, you can also conduct an HSL correction (HSL = hue, saturation, lightness): Click on 'HSL' and move the sliders for the individual parameters in the chosen directions. HSL filtering is useful to make pictures look "more colorful" or "grayer", for instance.

Nero PhotoSnap 29

5. Click on the icon if you would like to save the result and overwrite the original image. If you would like to retain the original image, click on the icon next to the 'Save' icon and add a file name. You can also change the type of file if you would like to save the image in another file format. Click on the 'Save' button to store the image and to close the dialog.

3.3.5 Changing the size

If the photograph you have taken is too large or too small, you can change its size to fit the chosen format.
1. Start Nero PhotoSnap and open the desired photograph. 2. Click on the 'Resize' effect to open the editing menu for this effect. In the 'Pixel dimension' area you can see the number of pixels (or a percentage) for both the width and height of the photograph, while at 'Document Resolution' you can view the width and height of the image in cm, mm or inches. 3. If you want to keep the proportions the same when you change the dimensions, ensure that the 'Constrain proportions' check box has been ticked. Please tick it if you have not done so already. 4. Specify the method to be used for changing the sizes by clicking on the dropdown button at 'Resize Mode' and highlighting the desired method. The standard setting is 'Lanczos', which leads to the qualitatively best results. If the

Nero PhotoSnap 30

'No image resampling' option has been selected, it will not be possible to change the pixel dimensions. Whether you change the pixel dimensions or the document resolution depends on why you would like to change the size. Generally speaking: If you would like to publish a photograph on a Website, for instance, you should enter the number of pixels. On the other hand, if you want to print an image, then you should state the exact size in cm, mm or inches. 5. Enter the desired value for either the width or height the other corresponding value will be calculated automatically if the proportions are to be kept the same. If the proportions are not to be retained, you will have to enter values both for the width as well as for the height.
6. Click on the 'Apply' button once you are satisfied with the results of the correction. The tool menu will then be closed. On the 'Current' tab you will then see the altered image and you will be able to see the stored image on the 'Saved' tab. icon if you would like to save the result and overwrite the 7. Click on the original image. If you would like to retain the original image, click on the icon next to the 'Save' icon and add a file name. You can also change the type of file if you would like to save the image in another file format. Click on the 'Save' button to store the image and to close the dialog.

3.3.6 Cropping
You can extract a chosen segment of a picture by cropping away the unwanted parts of the picture.
1. Start Nero PhotoSnap and open the desired photograph. 2. Click on the 'Crop' effect to open the editing menu for this effect. 3. Move the highlighted area to that part of the image you would like to cut off and use the sizing handles to define the segment to be cut away. This area will appear brighter in the preview window. 4. Click on the 'Apply' button once you have marked the chosen area and would like to trim it off. You will then see the results of this action in the 'Current' tab.

Nero PhotoSnap 32

3.3.7 Noise
The CCD chip in a digital camera makes a noticeable 'noise', above all when the ISO number is high. In other words, the darker pats of the image are particularly grainy.
1. Start Nero PhotoSnap and open the desired photograph. You will best be able to see the effect of this filter when using a zoom factor of 100% (original size). Click on the icon.

2. Click on the 'Noise' effect to open the editing menu for this effect.

3.3.8 Sharpening
The sharpness of a photograph does not solely depend on the resolution the contrast of an image also plays a role in creating the impression of sharpness. When sharpening a photograph, the edges are strengthened and the contrast of the individual elements of the picture is increased. The most common method of sharpening is called 'Unsharp masking' and it stems from analog photography. If a pale, indistinct negative of a photograph is placed over the original, it results in a picture that is sharper than the original. This term is still in use to this day. Sharpen the photograph once you have specified the desired image size, otherwise the effect could be lost.
1. Start Nero PhotoSnap and open the desired photograph. You will best be able to see the effect of this filter if you use a zoom factor of 100% (original size). Click on the icon.
2. Click on the 'Sharpen' effect to open the editing menu for this effect. 3. Move the sliders for the individual parameters until the required sharpness has been achieved.

Nero PhotoSnap 35

Instead of sharpening the image, you can also use a softening tool. Click on 'Gaussian Blur' and move the slider in the direction you would like.

3.3.10 Rotating
If the camera has been inadvertently held at an angle, this error can be remedied by rotating the image. When you rotate a photograph it will inevitably be cut at the edges (or else black bands will appear there). When cutting, Nero PhotoSnap attempts to retain the picture's aspect ratio. The "Size of the rotated image" option determines how the edges are to be treated. Either black edges will be added or the picture will be cropped. In the latter case you will be able to decide whether the target picture should be exactly as large as the original (to do this, the picture will first be cut and then restored to full size) or left at the cut size.
1. Start Nero PhotoSnap and open the desired photograph. 2. Click on the 'Rotate' effect to open the editing menu for this effect. 3. In the 'Size of the rotated image' section, specify how big the image should be after rotation by clicking on the dropdown button and highlighting the chosen option. If there is a horizontal line on the picture, such as the horizon or a vertical line, like a lamp-post, you can align the image along that line so that the line concerned is then horizontal or vertical. To do this, you must inform the program of this line. Click on the mouse button, keep it pressed down, drag across a line that you know to be straight and then release the mouse button. The photograph will then rotate in such a way that the line you have drawn will be either horizontal or vertical.

Nero PhotoSnap 39

Clicking on the 'Autorotate Image' button will instruct the program to automatically search for edges in the picture and then rotate it in such a way that most of the edges are either horizontal or vertical. 4. Select the desired option for rotation or click on in the rotation circle to specify the angle of rotation. (You can also enter the angle of rotation directly as a value.)

You can also change the type of file if you wish to save the photograph in another file format. Click on the 'Save' button to store the picture and to close the dialog.
3.3.11 Removing 'hot pixels'
With photos that have been taken using a long exposure time, individual pixels (so-called 'hot pixels') can become visible. These pixels may be red, green, blue or white. They occur as a result of different charging losses in the camera's CCD recording chip.

2. Click on 'Hot Pixel Fixer' to open the editing menu for this filter.

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 and by the height and width of the image gives the total number of pixels; an image of 800 x 600 pixels in size thus contains 480,000 pixels.

Resolution
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).
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.
