Hello All *Retouching photographs. Removing scratches and traces of dust.* Roman Sabalenko Since the computer became the main tool for image processing, ideas about working with photographs have undergone fundamental changes. But often we have to deal with correcting the flaws of the technology of the pre-computer era. In that including cleaning up the dirt... For those who are seriously involved in computer image processing, that is, artistic works in publishing, advertising, etc., and has scanner, one day there is a desire to put in order the accumulated Winchester photos and create a personal photo archive. However, putting it in taking pictures, especially old ones, is not so easy. The quality of photographs is often below acceptable. If shooting was not produced professionally or was not designed to be professional use that requires large format prints and careful storage, the picture may simply be disfigured by scratches, dust and other contaminants that interfered with the photographic process. The process of dealing with such troubles is called retouching and is well known photo artists. This is a painstaking and long process. However, computer processing images of topics is good, which greatly simplifies many things, you just need know typical techniques and become proficient in their use. Then it won't take longworry about the fact that an absolutely necessary photo for the archive is either is hopelessly damaged, or requires several days of fiddling before it can be will use. For example, a completely routine operation of removing scratches and other small details, which so poisons the lives of many computer artists. And this happens because, for old times’ sake, they are trying to cover up the damage using drawing tools and choosing colors. Sometimes a stamp is chosen for this, but it leaves noticeable scars on the image. Basically, in the Photoshop editor, the main tool for professionals in everything world, there is a special filter to remove scratches and dust. It's called Dust & Scratch. But its direct use for photography in general It’s almost impossible, since it completely blurs it. How right they are take advantage? Let's take a photograph that has damage in the form of thin black and white lines. Our first operation is to copy the image to a new level, for All you have to do in the layers palette is drag the Background layer onto the button that creates new layer. Having selected the copy layer for editing, apply the anti-scratch filter to it. He called up through the Filter/Noise/Dust & Scratches menu. In the quick window viewing, you need to adjust the most problematic place, after which, by askingUse the slider to adjust the radius of the damage to be repaired to ensure its complete disappearance. If in one place of the photo it takes too much to remove scratches in relation to other areas of the radius, you can process these areas separately. Choose the minimum sufficient radius. As you can see, the image on the copy layer is smeared, but it is completely All scratches are gone. Now we need to transfer some of the pixels (but not all!) from this layer on the original photo. It is more convenient to do this using a stamp. This one The tool allows you to transfer pixels into a picture not only from the neighboring part of the image, but also from another picture. This may be recorded on disk the version of the file being processed, which in our case is inconvenient, or the image, placed by the Photoshop editor in a special buffer - Snapshot (instant picture, if translated into Russian). This picture is taken through the Edit/Take menu Snapshot. First, let's remove the white scratches. Since for this we need from the buffer transfer only those pixels that are darker than those contained in the original picture, select the blending mode Darken. What is it? In this mode the original pixels are replaced only by those pixels from the buffer that are darker original. Darker points of the original than in the buffer remain unchanged. The size of the stamp brush should be chosen smaller to minimizepossible impact on undamaged areas of the image. Pick up at Brushes palette such a brush diameter so that it covers approximately twice the thickness scratches. Then you won’t have to painfully aim with the mouse, and at the same time you you will not smear left and right in its vicinity. The setup is complete. You can start removing white scratches. One time is enough for this draw the stamp along the line to be deleted and enjoy how it disappears without leaving scars and without introducing distortions into the original picture. Even graininess of the image, characteristic of a scanned photograph, remains unchanged. If you try to use a stamp without "extra" wisdom, repeating grains will appear, folding when decreasing the scale in moire. Black stripes should be removed in a similar way. The difference is that You need to select the Lighten blend mode in the stamp options palette. Acts like Darken, only those pixels that are lighter are replaced in the original picture located in the Snapshot buffer. Run the stamp over the black scratches - and how it wasn't here. The result is amazing. Compare two image fragments - before and after retouching, shown in the last picture. As you can see, scratches are not just covered with a color close to neighboring pixels, the texture of the photograph is preserved.Consequently, with its further use, traces of retouching will not float to the top and no one will guess that this photo had to be cleaned up. I think you understand the idea. This method can be successfully used for correction thin lines, but for large-area damage it is not very suitable. B In this case, an area will appear that is too blurred in relation to the rest. to the original. To avoid this, you can try to select on the copy layer for the restored fragment has a texture similar to the graininess of the original. Experience shows that the desired result can be achieved with such a stepwise approach. achieve a maximum of three steps. The quality of the retouched picture is achieved higher due to more subtle removal of minor damage than if immediately use the maximum cleaning radius in the filter. When, at the edges of, say, a white scratch, a darker than intact image pixels, halo (this is a consequence of computer interpolation when scanning or changing the scale and resolution of a photograph), After the first pass with a stamp in Darken mode, the halo will be transferred to the original. This can be avoided by using a smaller brush. You can also switch the mode to Lighten and stamp over the halo, treating it like to a dark scratch. And it’s best to simply scan the photo at maximumresolution or size to avoid interpolation. With best regards,
