![]() Yes, apologies for asking this rather stupid question: I found it for myself. Are there any special scanning requirements implied by negadoctor in darktable? Or in the equivalent in Rawtherapee (is there such an equivalent?). ![]() Later on I will be scanning colour negative film. Is this double scanning a good idea? How does it work? Unfortunately no examples of how to do it are given. So, where and how should I do dust and scratch removal? Steinhoff also talks about scanning in 64-bit RGBI mode, producing a raw file and then rescanning that in Vuescan to remove dust and scratches. ![]() I see some advice not to use the dust and scratch removal in Vuescan as this functionality impacts the image quality. The second issue is that the slides have dust and scratches. So, can somebody recommend a suitable set of parameters for scanning mostly Kodachrome, with a few Agfa slides too. I have read both of Sascha Steinhoff’s books on using Vuescan multiple times and just become more confused on how to set it up. The first issue that presents itself is the setting of the parameters (especially on the Input tab) in Vuescan. I will do post processing in either, or both, darktable or Rawtherapee. I wrote up a slide and photo scanning guide for the Epson software–let me know if you need it and I’ll see if I can dig it up.I’m wanting to digitise a large number of 40 to 60 year old slides and lpan to use Vuescan with my Nikon Coolscan V ED, in preference to Silverfast and my Epson V700 (I don’t have a Coolscan driver for Silverfast). A Windows 10 virtual machine will accomplish the same thing. I used a virtual machine with Mojave so that I could scan with the old 32-bit software. I found the 32-bit Epson software’s Digital ICE was much better quality than the VueScan and Silverfast infrared scanning dust removal options, maybe because it didn’t offer parameters so they were forced to tune it to work well from the get-go. The 64-bit Epson software no longer includes Digital ICE, unless they reinstated it since I was doing the slide scanning several years ago. Or live with the dirt, sometimes it’s aesthetically pleasing because it adds some old school charm to the shots. (Or put the non-DI version on top and cut out the areas that don’t have much visible dirt). ![]() Then, using Pixelmator or Photoshop or similar, put the Digital ICE version on top and cut out the artifacts to reveal the non-DI version underneath. If using the Epson software you can either scan your Kodachrome slides without Digital ICE, or for the ones that are particularly dirty (even after careful cleaning), you can do two scans: one with Digital ICE, and one without. If you end up using the Kodachrome-iSRD software David C. Yes, looking at the image you posted, the artifacts around the wheel wells and other locations are caused by Digital ICE with Kodachrome. if you have an installation with Kodachrome support, the software will automatically switch in the Kodachrome-iSRD software when you configure it for both iSRD and Kodachrome scanning. Depending on how old your bundled copy is, you may also qualify for upgrade pricing.Īccording to SilverFast, using infrared scratch removal (their “iSRD” option) requires special handling when used with Kodachrome. If you decide you want to keep it, you can buy a license key from their web site, which will permanently unlock all features available on the tier you paid for. You need to go up to the next tier (“SE+”) to get Kodachrome support. The least expensive version of SilverFast (“SE”) does not support Kodachrome. I do have the free version of Silverfast that came with the scanner and hate the UI! I’ll have to see if I can download a demo of the pay version to see if I like it better.Ĭheck out what version you have. ![]()
