Nero PhotoSnap General information • 5

1 General information

1.1 About Nero PhotoSnap Nero PhotoSnap consists of two applications:

Nero PhotoSnap (Editor) is a program for editing your favorite photographs. The variety of options available allow you to improve the quality of the photos and, of course, save the pictures you have edited.

Nero PhotoSnap (Viewer) is a program for displaying images and for rummaging through directories containing images. It does not allow you to edit or save photographs.

1.2 System requirements Nero PhotoSnap is installed together with NeroVision Express 3 - the system requirements are the same. You can find more detailed information on system requirements in the NeroVision Express 3 manual.

1.3 Installation Nero PhotoSnap is not installed separately but together with NeroVision Express 3. In other words, after installing NeroVision Express 3, you will automatically have Nero PhotoSnap as well.

Following installation, a dialog will appear that lets you link graphic files with the Nero PhotoSnap Viewer, so double-clicking on a file will open it in the Nero PhotoSnap Viewer. If you have not done this and would like to open the settings, then: Highlight an image file and click on the right-hand mouse button. Select the 'Open with' command from the pop-up menu and highlight 'Choose

program'. Select Nero PhotoSnap Viewer from the list of recommended programs, tick

the 'Always use the selected program to open this kind of file' check box and click on 'OK' to save the changes and to close the window.

You can also change the file allocations at a later stage. 1. Open the Nero PhotoSnap viewer. 2. Click on 'File' and select the 'File Associations' command. The file allocations dialog will open.


3. Highlight the formats that you would like to have Nero PhotoSnap Viewer linked with, in other words the image formats that will open Nero PhotoSnapViewer. 4. Click on the 'OK' button to save the changes and close the window. Warning: Please note that it is not possible to link the 'BMP' format with Nero PhotoSnap Viewer.

1.4 Formats supported Nero PhotoSnap supports the most common image formats, so that it is suitable for all kinds of image files.

1.4.1 Formats that can be read jpg jp2 (not PhotoSnap SE) tga pcd iff xbm gif png bmp tif pcx ras

3 Nero PhotoSnap

3.1 Launching Nero PhotoSnap You can start Nero PhotoSnap in three different ways: Via Nero StartSmart, the 'command center' of the Nero family of products. Start > (All) Programs > NeroVision Express 3 > Nero PhotoSnap. By Clicking on the 'Edit' button in Nero PhotoSnap Viewer.


3.2 Editing images

3.2.1 Opening an image

1. Launch Nero PhotoSnap.

2. Click on the icon and switch to the directory containing the desired image. Highlight the image and click on the 'Open' button. The chosen image is now ready to be edited.

Two tabs ("index cards") will appear once you have opened the image. The 'Saved' tab will show you the image as it has been stored and the 'Current' tab will show you the image as it looks at the moment (though without having been saved.)


3.2.2 Selecting filters

The right-hand area of the Nero PhotoSnap window shows you the filters available for editing images.

The first column contains the filters that are shown when Nero PhotoSnap is started. Additional filters are displayed when you click on 'Other effects'.

1. Start Nero PhotoSnap and open the desired photograph.


2. Click on the filter you would like to use in order to open the editing menu for this filter.

After you have opened the filter, two new tabs will appear that provide a preview.


3.2.2.1 Activating a Preview

There is a preview dialog for most filters, but not for all.

When you have selected a filter, you can open a preview image showing the filter effect in two miniature images (before / after). Tick the corresponding check boxes in the filter area.

If this check box has been ticked, you will see the opened photograph as it would look before and after using the filter.


The first preview tab shows you how the photograph would look when using the filter.

In the second preview tab you will see the current image (left) and right the image when using the filter.


3.3 Filters Nero PhotoSnap offers you a great many filters for editing images. They are not all explained in this QuickStart – only the most important are dealt with here.

Try out for yourself the filters that are not described here – it is not dangerous, because the changes will only be saved if and when you want them to be.

A detailed explanation of these filters would be well beyond the scope of this QuickStart manual, and so it has been left out.

It is also possible to apply a number of filters on one image, one after the other!

3.3.1 Preset filters

If you use filters particularly often, you can also create a template (a preset) and use it later. You can load the preset at any time to call up the saved filter action.

3.3.1.1 Creating a preset filter

1. Start Nero PhotoSnap and open the desired photograph. Then click on the filter you would like to use.

2. In the 'Presets' area, click in the text box and assign a name to the filter preset.

3. Perform the desired action(s) and click on the 'Save' button once you are

satisfied with the result.

3.3.1.2 Loading preset filters

1. Start Nero PhotoSnap and open the desired photograph. Then click on the filter you would like to use.

2. In the 'Presets' area, click on the dropdown button and select the desired preset. The action(s) saved will then be performed automatically.


3.3.1.3 Deleting a preset filter

1. Start Nero PhotoSnap and click on the filter that contains the preset you want to delete.

2. In the 'Presets' area, click on the dropdown button and select the desired preset.

3. Click on 'Delete' to remove the preset.

3.3.2 Automatic correction


2. Click on the 'Autofix Image' filter in order to open the editing menu for this filter.

3. Select the filter that should be automatically carried out or disable the ones that should not be used.


The preview will show you the image after using the automatic adjustment feature.

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 right-hand 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.


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).


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


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 After

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.'


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.

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.


3.3.4 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.


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 pipette to click on the desired section.


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.

Before After


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.



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.


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


'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.



3.3.6 Cropping

You can extract a chosen segment of a picture by cropping away the unwanted parts of the picture.


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.


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.


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. Move the slider to the desired filter size, either to remove noise or to add it. 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 and you will be able to see the stored image on the 'Saved' tab.



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.


You will best be able to see the effect of this filter if you use a zoom factor of


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.


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.

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 - you will be able to see the stored image on the 'Saved' tab.



3.3.9 Red eye removal

If you use a flash, it will often happen that people being photographed appear to have red eyes (actually pupils) instead of their real eye pigmentation. The red in the pupils comes from blood in the choroid (a layer of tissue at the back of the eye, containing a large number of blood vessels) which becomes visible because the iris cannot close quickly enough. This effect is stronger the nearer to the camera's lens aperture the flash is positioned. In other words, the problem is worst with the most popular compact cameras.


2. Click on the 'Red eye removal' effect to open the editing menu for this effect.

3. Use the mouse to mark the area with the reddened eyes.

You can mark the area quite generously because the filter will only change the red values, replacing them with gray values.


4. Move the slider to define the degree of reduction. The further left the slider is, the less will be recognized as red (and thus converted). The further right the slider is moved, the more will be distinguished as red.

5. Click on the 'Next' button once you are satisfied with the results of the correction and you would like make a further correction to the picture.

6. Repeat stages 3 to 5 if you would like to remove the red eyes from another part of the picture.

7. Click on the 'Apply' button once you are satisfied with the results of the correction. The tool menu will then be closed. You will then see the altered image on the 'Current' tab, while you will be able to see the stored image on the 'Saved' tab.



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.


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.


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.)


5. Click on the 'Apply' button once you are satisfied with the results of the correction. The tool menu will then be closed.

6. Click on the icon if you would like to save the result and overwrite the original image. If you want 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 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.


You will best be able to see the effect of this filter if you use a zoom factor of


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


3. Move the slider to define the intensity of the correction. The further to the left the slider is, the fewer the number of pixels that will be interpolated – the further to the right, the more pixels that will be interpolated.

4. Click on the 'Apply' button once you are satisfied with the results of the correction. The tool menu will then be closed.

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 photograph in another file format. Click on the 'Save' button to store the picture and to close the dialog.


3.3.12 Other filters

Nero PhotoSnap also offers additional filters that you can edit your photos with.


2. Click on ' Other Effects' to display them.

3. Click on the desired filter to use it either directly (e.g. with 'vignetting') or in order to open the editing menu.

4. Choose the desired option and click on the 'Apply' button once you are satisfied with the results of the correction. The tool menu will then be closed.


Of course, you can also use a number of filters one after the other!

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 photograph in another file format. Click on the 'Save' button to store the picture and to close the dialog.

3.4 Toolbar

The Nero PhotoSnap toolbar contains many simple functions for dealing with photographs and for configuring the program.

Opening a file. Clicking on the arrow icon will display the last files to have been opened.

Saving the open file. Clicking on the arrow icon will display the 'Save as' command. It is possible to change the file name as well as the file format. If the file format allows particular settings, the 'Settings' command will also be active.

Undoes (reverses) the last action. Clicking on the arrow icon will show the 'Undo last Step' and 'Undo all' commands

Restores the action that has be undone.

Nero PhotoSnap Glossary • 47

5 Glossary

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.

HSL

In HSL mode, the color is described on the basis of its Hue, Saturation and Lightness.

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.

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.

Pixel

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).

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.
