Photo Side-by-Side is very easy to use. The first step is to open two photos in the application. The two photos will be shown side by side. Then you can zoom in or zoom out each photo separately or in parallel. You can apply color adjustments such as brightness or contrast, or rotate and flip the photos. To make a better evaluation you can also show a ruler with actual size scale. To show the ruler in actual size scale, you will have to first specify the already known actual distance between any two points of the photo. Then you will be able to also measure the distance between any two points of the image. You can also overlay the two photos. With the above actions, you will be able to compare two photos side by side and make an assessment. You can also save comments for each image which will help you further in next evaluations.
A. Select "Open" (Ctrl+O) from the "Main Photo" menu and then select the two photos that you want to open. If the photos are in separate folders then open one "Main Photo" and then select "Open" (Ctrl+Alt+O) from the "Comparison Photo" menu to open the comparison photo.
B. You can also open photos in Photo Side-by-Side with a drag and drop of them on the application's window.
C. You can also open photos by right-clicking on them in the Windows File Explorer and then by selecting "Open in Photo Side-by-Side" from the context menu. In order that the "Open in Photo Side-by-Side" context menu item is shown in Windows Explorer, it is necessary that you check "Integrate into Windows Explorer" during the installation of the application.
D. You can also reopen recently opened images by moving the mouse cursor above the button "Recent Images" that is on the bottom of the application's window. Then a new window will appear with thumbnails of the recently opened images. Just click on a thumbnail to open the image. You can check "Open as Left Image" to open the image as the main photo or you can check "Open as Right Image" to open the image as the comparison photo.
You can zoom in or zoom out with the following ways :
A. Just hold the Control (Ctrl) key and then click with the left mouse button on the image to zoom in at the specified point. To do a zoom out just hold the Control button and then do a right mouse button click on the image.
B. To zoom in both images in parallel, i.e. to zoom in both images at the same point, hold down the Shift key and then do a left mouse button click on the image. To zoom out in parallel just hold down the Shift Key and then do a right mouse button click.
C. Just use the image's zoom slider that is below it to zoom in or zoom out the image. To zoom both images with the zoom slider check the "Both" checkbox that is on the left of the comparison photo's zoom slider.
D. Just enter the zoom percentage on the left of the image's zoom slider and then press the Enter key or select a zoom percentage from the list.
E. Select "Zoom into Selection" from the "View" submenu of the "Main Photo" menu or "Comparison Photo" menu. Then you will have to specify a rectangle on the image as a selection that will be zoomed in. Just click on the upper left corner of the selection area and then move the mouse cursor to the right lower corner of the selection area and click the mouse button again to zoom into the selection area.
To move the position of an image you can use the horizontal or vertical scrollbar that is next to it. You can also hold down the Shift key and then both images will scroll. Alternatively, you can click on a point of the thumbnail of the image and the image will be centered on this point. The orange rectangle on the image's thumbnail does show the area of the image that is shown. Hold down the Shift key and then click on a point of the image's thumbnail and then both images will be centered on this point. You can also move an image by holding down the left mouse button and dragging it.
To show the images in full-screen mode, select "Full Screen" from the "View" submenu of the "Main Photo" menu. To show only the one photo in full-screen mode select "Single Photo Full Screen" from the menu.
To store comments for an image simply enter them on the textbox that is below the image and they will be automatically stored on the application's database. The application uses the relative path to the application's "Base Directory" to identify the image and get its comments from the database. You can change the application's "Base Directory" in the application's settings screen.
To change the brightness or contrast of an image select the "Brightness/Contrast" menu item from the "Adjustments" menu. Then move the sliders on the window that is shown, to change its brightness or contrast.
To rotate or flip an image select the appropriate "Rotate" or "Flip" menu item of the "Photo" submenu of the "Main Photo" or "Comparison Photo" menu.
To print the photos along with their comments select the "Print" menu item from the "Main Photo" or "Comparison Photo" menu. Select "Print Both Photos" to print both photos. You can also see a preview of the print by selecting "Print Preview" from the menu and select the "Print Settings" menu item to set the various print settings. You can also print the images with your personal details as they are specified in the "Settings" screen of the "Tools" menu.
To overlay two photos in order to make a better evaluation first open the two photos and then select "Overlay" from the "Main Photo" menu. Then the main photo will get overlaid with the comparison photo. A new small window will be shown. Press the button with the green arrows to move the overlaid picture and use the "Transparency" slider to change the transparency of the overlaid image. Check the "Grayscale" checkbox so that the overlaid image is only shown in grayscale. Press the "Close" button to exit and show both images normally again.
To show information about the image such as its file date, file size and image size select "Info / Comments" from the "Main Photo" or "Comparison Photo" menu.
To show a grid above the images press on either the "Cross Grid" button that is on the lower side of the screen or the "Multiple Grid" (Cross Hatch Grid) button that is next to it. To remove the grid from the images press on the "No Grid" button.
To show a ruler for the images select "Ruler" from the "View" menu. To set the ruler scale mode (centimeters, millimeters, inches, points or pixels) select the desired scale mode from the "Ruler Scale" menu item.
To show the ruler with the actual size scale of the image you will have to first specify a known distance between two points. Select "Set Actual Size Scale" from the "Main Photo" or "Comparison Photo" menu. Then click on two points of the image for which you know their distance in reality. Then in the new window that will appear specify their distance in reality and press the "OK" button. Afterward, the ruler scale will change to the actual size scale. The actual size scale for the image is also stored in the database so that you will not have to specify it again in the future, once it was set.
To measure the actual distance between two points of the image you will have to first set the actual size scale as it was mentioned earlier. Afterward, select "Measure Distance" from the "Main Photo" or "Comparison Photo" menu and then click on two points of the image for which you want to know their distance. After that, a message will appear that will display their actual distance.
To convert the image into its negative or into grayscale, select "Negative" or "Grayscale" from the "Adjustments" submenu of the "Main Photo" or "Comparison Photo" menu accordingly.
When the application is first started it asks you for your desired user interface language.
You can also change the user interface language from the "Language" menu.
