Page 6 of 7 It also helps to continually make slight changes to your cloning point as you progress. This reduces cloning artifacts (tiny duplication of details). In addition, change the size of your brush even while doing the same section. It will facilitate better blending of the cloning. 9. Size The Photo At some point, youll need to size your photo for printing to a printing resolution. The size of the photo affects sharpening, so its usually best to do sizing at the end of the process, just before sharpening. Image resolution is different from printing resolution. To set a printing resolution, go to the Image Size (or Resize in Elements) option under the Image menu item. First, be sure the Resample box isnt checked. Type in a printing resolution between 200 and 300 ppi; this will tell you how big the image can be printed using the original pixels. If it isnt big enough at 200 ppi, check Resample and type in a larger size in the dimensions area. Use Bicubic Smoother (or just Bicubic if you have an older version of Photoshop) for enlarging photos. If the photo isnt small enough at 300 ppi, also check Resample and type in a smaller size, then use Bicubic Sharper. 10. Sharpen Sharpening should be done at the end of the process to minimize some adjustment problems. Noise is one element that can be adversely affected if sharpening is done too early. Unsharp Mask is a standard (the name refers to a commercial printing industry process used for sharpening). Try these settings: Amount130 to 180 (depends on detail; Amount refers to the strength of the sharpening); Radius1 to 1.5 (depends on image size; Radius is based on how far Photoshop looks for tonal differences to affect); and Threshold0 to 10 (depends on noise in the photo; most digital cameras do well with 2 to 3 unless theres a lot of noise; Threshold relates to the tonal difference where Photoshop starts making changes to edges). Dont oversharpen. You can tell when an image is oversharpened when it loses some of its subtle tonalities and starts to look harsh. Another sign of oversharpening is when halos appear around strong contrasts in your photo (you can see them in the preview box if you move your cursor over the photo and click on a contrasty edge; it will appear in the preview). |
