Does anyone have any tips for removing vignetting created by the film camera’s lens? It seems like applying a radial mask in Lightroom can help, but you have to correct for the exposure slider adding orange (maybe from the film base?) using white balance; also I’ve noticed it sometimes helps to re-convert the image (not the end of the world). Playing with different inverted sliders can help, but its a bit headache-inducing. I know you could also just create a positive copy and then correct it on that, which would probably work fine - I’m looking for ways to keep the number of copies down for spaghetti-management reasons. ---

Correct vignetting, export to 16 bit TIFF and use NLP from there on. This should help prevent color shifts… at the price of huge files. ---

never had any problems from vignetting produced by film camers lens I had problems produced by macro lens upon digitizing process - LR’s built-in lens profile usually helps + adjusting vignette setting manually. Can you provide some examples of what is actually happening? ---

Since it’s a negative, vignetting on the scanning lens would actually brighten the corners! I just mean plain old vignetting on the taking lens, the kind you would remove trivially if it were a digital photo. I’m mainly asking to see if anyone has any novel approaches. ---

> [@edbr](#): > > I’m mainly asking to see if anyone has any novel approaches. Take scissors and cut the inner part out in a way that vignetting is eliminated. Novel enough? 😇 Other than that: If your scanning lens has some vignetting and you put it up to compensate the original vignette, you might be just fine. Nevertheless, some loss of quality might be visible due to the superposition of two less-than-ideal situations. ---

isn’t it fixed naturally by vignetting upon digitizing then? 🙂 still: just try vignette tools in LR (or other editor) ---

if vignetting is already present on the film original, you have no choice but correct it **after** conversion to positive - otherwise the color balance of the shot will be completely thrown off. ---

Ah good to know! I think the export to TIFF and correct is the only reasonable way. I suppose you could automate this. ---

Certain film lenses have rather more vignetting than a Canon 100mm 2.8 Macro L 😂 ---

A planar light panel a give a homogeneous light distribution on film, provided it is infinitely large compared to the film, which is not practical for table-top solutions. It took me a while to get this done, but I just calculated the brightness inhomogeneity on a film that results from using a planar light source tha… and this: > [@Integrating sphere as a uniform backlight](https://forums.negativelabpro.com/t/integrating-sphere-as-a-uniform-backlight/6302/66): > > Small update: I managed to quite accurately create a brightness mask in LRC. The procedure is as follows: Take a shot of a blank B&W negative Import with Linear B&W profile (e.g., NegativeLab v2.3 B&W) Analyze the variation of brightness (if any) in LRC in the development module by hovering over the frame and looking at the R, G, and B values: They should be the same (since B&W) and constant across the frame Crop to see only the blank negative Apply a radial mask: My light panel is square, so…
