Shows the current image in the left pane and in the right pane how the image would look if the current filter were applied. This tab is available only if a filter is selected. Synchronizes the view of the left and right images, i.e. if the left image is enlarged, the right image is also enlarged and vice versa. button If the button is deactivated, the views are not synchronized. This button is available when the Split preview tab is displayed. In the Tools area, effects are available that you can apply to images (see Image Effects). The following buttons are also available: Other effects Shows additional effects. Back to main effects Shows the main effects. The main effects are particularly useful for correcting imperfections in the digital image caused by, for example, a faulty shot or a faulty scan. The other effects are used for artistic editing and creative image manipulation. Page 10 Image Effects 5 Image Effects When an image is open, you can switch between main effects and other effects in the Tools area with the Other effects and Return to main effects buttons. The main effects are particularly useful for correcting imperfections in the digital image caused by, for example, a faulty shot or a faulty scan. The other effects are used for artistic editing and creative image manipulation. The following main effects are available: Original image Automatic correction Exposure Color balance Shows the Automatic correction area where you can automatically perform corrections. Depending on what you want to do, you can remove color cast, poor exposure, tilting and/or image noise. Shows the Color/Exposure area where you can correct the exposure automatically or manually (see Exposure Area). Shows Color/Color balance area where you can increase or decrease the individual color values and in this way correct color cast or create special effects (see Color Balance). Example: in the sample image the amount of red is reduced. Resolution Crop Shows the Resolution area where you can change the pixel size, resolution and/or print size of the image (see Resolution Area). Shows the Crop area where you can extract (crop) part of the image. Page 11 Image Effects Shows the Lens distortion area where you can offset pincushion or barrel lens distortion. Lens distortion Brightness and contrast Example: the sample image has barrel distortion. Shows the Brightness and contrast area where you can adjust the brightness and contrast.

Cancel Cancels the action and shows the Tools area. Show preview Shows the Filter preview preview window. Here you see the saved image above and the edited image below. Fig. : Filter preview window 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. Page 17 Image Effects 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 two lines that define the brightness range are shifted. 3. If you want to adjust the brightness range manually: 1. Move the left line. Æ The beginning of the brightness range is defined. 2. Move the right line. 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. Page 18 Image Effects 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. Æ A control point is set. Fig. 4: Exposure area, Gradation curves tab -- drawn gradation curves with control points 3. Pull the curve upward or downward to lighten or darken the hue values of this area. 4. Click the Apply button. Î You have adjusted the exposure. The histogram of the edited image then shows a changed profile. If you are not satisfied with the change, you can reset to the default value with the Reset button. Page 19 Image Effects 5.3 Color Balance You can correct the color of the image 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. Fig. 5: 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 following input options are available: Red / Green / Blue 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%). Auto remove color cast Automatically balances a present color cast. 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. The following input options are available: Hue Regulates the primary colors. Slide the regulator to the right or left to change the primary color hue of each pixel. Saturation Regulates the saturation of the colors. Slide the regulator to the right to increase the saturation or to the left to decrease. Brightness Regulates the color lightness. Slide the regulator to the right to increase the lightness or to the left to decrease it. Page 20 Image Effects 5.3.1 Color Balance You can perform a color balance or correct a color cast with Nero PhotoSnap. You can perform the color balance manually, semi-automatically, or automatically. The following prerequisite must be met: The Color/Color balance area is displayed. To correct the color of an image, proceed as follows: 1. To perform a manual color balance: 1. Click the RGB tab or the HSL tab. Æ The RGB tab or the HSL tab is displayed. 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. 2. Slide the regulator as required. Æ The image shows the changes. 2. To perform a semi-automatic color balance: 1. Click the RGB tab. Æ The RGB tab is displayed. 2. Move the cursor over the image. Æ The cursor displays as a pipette. 3. Click in an area of the image with a neutral color, e.g. gray. Æ The regulators are moved accordingly and the image shows the changes. 3. To perform an automatic color balance: 1. Click the RGB tab. Æ The RGB tab is displayed. 2. Click the Remove color cast button. Æ Nero PhotoSnap analyzes the color distribution. The regulators are moved accordingly and the image shows the changes. The automatic color balance is based on the analyzed features and balances color casts automatically. If you are not satisfied with the corrected image, remember that a color balance is a matter of taste and that a color cast may in fact be desired in order to impart a certain mood. 4. Click the Apply button. Î You have performed a color balance. Page 21 Image Effects 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 Retains the proportions of the image. check box Combo box entry Do not resample image Combo box entry Nearest neighbor Combo box entry Bilinear Combo box entry Changes the pixel size of the image; the image is not recalculated if there is a major change. 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. 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. If there is a size change, the image is re-calculated by taking into Page 22 Image Effects 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. If there is a size change, the image is recalculated by taking into account all adjacent pixels during the recalculation. Combo box entry Bicubic Combo box entry Lanczos 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 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, Page 23 Image Effects green and blue. Auto profile Automatically reduces noise. The regulators are set to an optimal value. Add Noise tab Noise levels 5.6 Defines the level of general noise increase. 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. Page 24 Image Effects 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. You can change the size and position of the ellipse by dragging the corner points. 2. Click the Continue button. Æ The marked area is defined. 3. Repeat the two previous steps for each pupil from which you want to remove red eye. 4. Move the Intensity of red eye reduction regulator. Æ The black color of the pupils will be increased or reduced, depending on the initial state. The regulator changes all areas marked in the image. 5. Click the Apply button. Î You have removed red eyes. Page 25 Image Effects 5.8 Rotate Area Nero PhotoSnap lets you rotate the image or image content. Fig 9: Rotate area The following configuration options are available in the Rotate area: No rotation The image is not rotated. Left/Right 90 degrees Rotates the image 90 degrees to the left or right. 180 degrees Rotates the image 180 degrees. Custom angle Rotates the image by any number of degrees. Background color Defines the background color for unfilled areas that occur when rotating. Autorotate image Rotates the image automatically by looking for edges; the image is rotated so that most edges are horizontal or vertical. The following items are available in the Size of the rotated image selection menu: No cropping Does not crop the image and fits the rotated image in an outer frame with horizontal and vertical edges. The newly created area is filled with the selected background color. Page 26 Image Effects Crop image Crops the rotated image so that no background areas are visible. Crop but keep image size Crops the image like Crop image but increases the size of the crop so that the dimensions of the rotated image are the same as the original. 5.8.1 Rotate Image Nero PhotoSnap lets you rotate an image. You can rotate manually, semi-automatically or automatically. The following prerequisite must be met: The Rotate area is displayed. To rotate an image with Nero PhotoSnap, proceed as follows: 1.

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. Fig. 11: JPEG settings window The following setting options are available in the JPEG settings window for JPEG/JPG images: Compression Regulates the compression strength. Page 31 Save Image quality Progressive compression Uses the progressive compression method for JPEG images. If a progressively compressed JPEG image is accessed and transmitted in the Internet, the image is displayed layer by layer. The user sees first an unsharp image that becomes increasingly sharper. The following check boxes are available in the PNG configuration window for PNG images: Convert current image to 256 colors (dithered) Reduces the color depth to 256 colors and thereby reduces the file size.

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. Page 40 Glossary 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.
