How to Remove Car Window Reflection in Photoshop
Adobe Photoshop is one of the most useful programs on the market for restoring or retouching photographs. It has an array of tools and functions that allow the user to alter virtually any aspect of a photograph they choose. Often this is accomplished by using a combination of several tools rather then a single one. An example would be window reflections. If you have taken a photograph of someone sitting in a car and the person's face is partially obscured by a reflection, it is often possible to repair this problem in Photoshop.
Load the photograph you want to retouch onto your computer, either by scanning it in (if it is printed) or by connecting your digital camera to the computer via the USB cord and transferring the photograph.
Open Photoshop. Select "File" and click "Open." In the dialog that pops up, browse to the photograph you loaded and open it.
Select "Image" and click "Image Size." In the dialog that pops up, change the "Interpolation" to "Bicubic Smoother." Double the pixel width, height and resolution; this will improve the results, especially if the image was scanned in using a scanner having limited resolution..
Select the "Lasso" tool from the toolbar. Use it to draw a selection around the reflection in the car windshield. Try to keep the selection restricted to the area you want to repair.
Select the "Clone Stamp" tool from the toolbar. Hold down the "ALT" key on your keyboard and click on an area of the car window outside the selection that has a color and appearance that most closely matches what the selected area would look like without a reflection.
Use the tool to draw over the reflection in the car window. You will probably have to use the "ALT" key several times as you work to select new reference areas for the "Clone Stamp" tool.
Select "Image" from the menu, then "Adjustments" and click "Levels." In the dialog that opens select the far right slider under "Input Levels" and move it slightly to the left. Then select the middle slider and move it slightly to the left. The exact amount will vary with each photograph, so you will have to judge this by eye using the preview. When you are satisfied click "OK."
Select "Image" and click "Image Size." Change the size and resolution back to what it was. Save your photograph as a high resolution JPEG image.
