soboyle www.oboylephoto.co Posted November 25, 2003 Share Posted November 25, 2003 I have some 20 year old Tri-X negatives that I have scanned, the grain is huge, partly because its tri x, and partly the age of the negs (probably poor development that reticulated the grain). Anyway, I'm looking for any photoshop techniques or tricks that might mellow out the grain a bit while keeping the image sharp. I tried copying the layer, bluring it and them changing the transparency. It is somewhat successful, but the blurred effect, while making the tone of the photo better, makes for a soft print. Any other tricks for this type of problem? Link to comment Share on other sites More sharing options...

chris_ladoulis Posted November 25, 2003 Share Posted November 25, 2003 I usually use the Filter/Noise/Median on a 2nd layer. You might prefer that to blurring. Try different radii and experiment. Link to comment Share on other sites More sharing options...
glen peterson Posted November 25, 2003 Share Posted November 25, 2003 There is a feature on Paint Shop pro 7, which I keep on my pc still, that is call Edge Preserving Smooth. This has helped me alot in the past with grain, and although it does some blurring, it isn't as bad as you might think. Link to comment Share on other sites More sharing options...
glen peterson Posted November 25, 2003 Share Posted November 25, 2003 FOllow up, EPS on PSP7 is also on PSP8, I think you can still download a trial of PSP8 from JASC. But it does have to be used in very low levels, between 2-5, otherwise things end up looking very fake.. Link to comment Share on other sites More sharing options...
alexdi Posted November 25, 2003 Share Posted November 25, 2003 Try Neat Image. Or create a new layer with a copy of the image, change the blend mode to 'Lighten', and shift it up and to the left by 2 or 3 pixels. Or you could scan in color, which would give you far more noise removal options. DI Link to comment Share on other sites More sharing options...
william_yu Posted November 26, 2003 Share Posted November 26, 2003 I am using the NeatImage on my color negative scans, and it is pretty good. I use NeatImage to process the raw scan before I open it in Photoshop. I also downloaded the trial version of Grain Surgery 2 at www.visinf.com, but got an error message (I use Windows XP Professional, 2.6 GHZ CPU, and 2 GB RAM). Because it is a trial version, I did not get any response from the tech support on fixing the error or uninstalling the GS 2. I also tried the Vuescan software because it is recommended by a lot of users. For my purpose (color negs), it does not remove more grain than my OEM Minolta software, and the color is on the cyan side, therefore I did not buy it. Hope this helps.

soboyle www.oboylephoto.co Posted November 27, 2003 Author Share Posted November 27, 2003 As a follow up, I tried Neat Image and am quite impressed, it took what were Very grainy shots and made them usable for 13 x 19 prints, something I couldn't have done with the originals. I found that if I combined the neat image processed image with the original and used layer transparency I can tweek the amount to grain I want to show and retain a nice tonal range in the print. Thanks for the tips Link to comment Share on other sites More sharing options...
