If you are working with a TIFF file, make sure you do NOT use Lightroom’s colorpicker to sample the film mask - this is a step that is only helpful for RAW DSLR scans or RAW DNGs from Vuescan/Silverfast.In most cases, though, this cast should be easily corrected by either the “AutoNeutral” / “AutoWarm” WB settings or the static film profiles (which add warmth to offset the mask).īut if that isn’t enough, here are a few things to look out for: (If the digitization is extremely under-exposed, it could exacerbate unevenness issues during processing)īefore color correcting, most color negatives will have some blue/cyan color cast to them (the inverse of the orange mask). Shoot manual and expose with your DSLR so that the negative is just right of center in preview histogram on camera.Make sure your aperture is at f/8.0 to avoid lens vignetting.Shoot the emulsive (matte) side of film facing towards camera (it’s less reflective and less likely to catch the light reflecting back from your camera/lens).Take off any filters that are on your lens (like UV filters).For instance, if your negative is quite far from the diffused light, the film holder will cast a shadow around the edges, leading to bright orange edges (because it’s inverted) Make sure your negative is close to whatever is diffusing the light.Make sure it is a bit wider than the negative itself. Some dark construction paper with a mask cut out will do. If you are using a light pad, make sure to mask out any light that isn’t directly illuminating the negative.It’s crucial that you follow the best practices for scanning with a digital camera to avoid these issues. This means that somewhere in your scanning process you either have uneven light hitting the negative, or you have light reflecting on your lens, camera sensor, or film surface. ![]() If you are DSLR-scanning, one of the most common issues I see is getting orange “blobs” across your image, orange “leaks” around the edges. ![]() “I’m converting a black and white photo, but it is showing up as having a tint to it, and not pure black and white” “When Lightroom syncs my conversion to mobile or web, they get messed up” “My DSLR-scan has orange blobs or orange edges”
