Engraving photos is a unique way to create keepsakes with your memories. Photos can be engraved onto a variety of surfaces, including marble, wood, metal and glass. When choosing a photo to engrave, it is important to understand that some make better candidates for the engraving process than others. Optimizing an image for engraving involves taking steps to select the right type of image, improve its contrast and detail, and possibly covert the image to a halftone screen.

Choose a high-resolution image at the size you would like the final result to be. For the purposes of photo engraving, a resolution between 200 and 300 dots per inch (DPI) should be adequate. If you are starting from a physical photograph, the image must be scanned to the above specifications, as forced enlargement of the image may produce poor engraving results. Scan the image in a color mode, even if it is black and white, so you will have more ways to adjust its quality.
2Determine if your image contains a variety of values that are distributed across the entire photograph; in other words, it should not contain large areas that are all black, all white or all gray. If your image is primarily a face, make sure that it is well-lit so that this variety of values is achieved. If this is not the case, you may want to select another image.
3Open the image in your computer's imaging software and adjust the contrast to optimize values for engraving. Adobe Photoshop contains a helpful item called the "Dodge/Burn" tool that allows you to lighten or darken specific areas of your photograph. This tool is especially handy for lightening shadow areas that may contain detail that may not engrave if not lightened.
4Save the image in "Grayscale" mode. The file should have the characteristics that you need to send it to the engraver; if you are engraving yourself, proceed to Step 5.
5Open the image in the engraving software; this will allow to you to preview what your image will look like on a variety of surfaces. If you do not have engraving software at hand, open the image in your imaging program and convert it to Bitmap format; this allows you to create a halftone screen, which is a monotone image that makes the engraving process possible. Consult your engraving equipment manual for what type of halftone screen will work best with the material that you plan to use. Keep in mind that if you are using a dark material -- such as black marble -- the image's values must be inverted before engraving takes place.
