shanefking Posted March 14 Share #1 Posted March 14 Advertisement (gone after registration) I've figured out a suitable workaround for cleaning up individual images taken using a corroded M9 or Leica S2/S-E sensor. First, take a photo of your dog. Notice the corrosion effects scattered all over the image, most visible along the evenly colored out of focus area on the left side of the image. Second, take a Corrosion image by photographing a well lit but also neutral background, such as a white wall or a cloudy sky (as used in this example). This will highlight the corrosion. Be sure to use the same F stop, because a different one will have a different effect. If possible, try to have the focus at the same distance as well. Third, in Photoshop, place the corroded image over the target image, and set the blend mode to OVERLAY Next, apply the following image adjustment layers only to the Corrosion layer: INVERT: this will allow the lights and darks of the corrosion image to cancel out the effects on the target image BLACK AND WHITE: This will eliminate the color cast that may be present on your corrosion image CURVES: You may need to bring up the shadows and midtones on the corrosion layer in order to match the original tones on the target image.

shanefking Posted March 14 Author Share #2 Posted March 14 (edited) And there you have it, a much cleaner image. You'll still have soft spots and agitated bokeh where the corrosion was, but it will be much better. Clear enough to catch the light drizzle of rain that day. Welcome, dear visitor!

shanefking Posted March 14 Author Share #3 Posted March 14 Finally, here's the work. You can save this as a template and apply it to other images in need of love. Feel free try it out using my sample images from the first post. I hope this is helpful to users in the future. -Shane Welcome, dear visitor!

davidmknoble Posted March 15 Share #4 Posted March 15 This is a really smart way to deal with the corrosion! I don’t have the problem, but the blending is unique. Very nice and well documented! 2 1 Link to post Share on other sites More sharing options...
