My earliest scans were done on a Minolta Dimage Scan Elite F-2900 film scanner (2820 ppi optical resolution), and Vuescan. (lens: Rodenstock APO-Rodagon D 75mm f/4.0). Most recently, I have been using a 16MP Fuji mirrorless camera with resolution of 4896 x 3264 pixels. My digitizing method has changed over the years. If I think a film scan needs additional sharpening, I usually start by increasing the Radius first, rather than the Amount. I am very sensitive to oversharpening and would prefer to leave my film images a little soft rather than risking oversharpening. Masking: Usually left at Lightroom Default of 0, but sometimes increased if there is a lot of noise or objectionable grain. Can create scripts for batch processing.Ĭlick to expand.Generally speaking, I will choose the following Lightroom "Detail" (Sharpening) settings for digitized 35mm film:ĭetail: Usually left at Lightroom Default of 25, but sometimes reduced if there is a lot of noise or objectionable grain. Also interactive preview in the sharpen tool. I would start at Amount: 35 (percent?), radius 1.0. With a simple console script, you can process dozens or hundreds of files in one go. With 0 being shorthand for auto-radius, 1.4 my starting value for sigma (often called radius in other software), 1.0 the amount (equivalent to 100% in other software notation) and 0.02 a plausible value for thershold, to avoid sharpening the noise. Magick convert infile -unsharp 0x1.4+1.0+0.02 outfile Depending on circumstances, I may apply USM sharpening in one of three environments: Like most other processing options, this is best left to post-processing. In vuescan (what I use), in the Filter tab, there is a "sharpen" option with just two values: OFF or ON. Click to expand.I don't know which scanning software you use.
