The k spectra were derived from optical transmission spectra of KBr pellets containing dispersed dust and the n spectra were estimated with …
Webb18 nov. 2011 · Another compromise: the infra-red image (dust.png) is offset with respect to the image. If this offset varies between scans, finding it every time would be a lot of hassle. Instead, dust.png could be blurred before the "-level", enlarging the apparent dust spots. However, this would correct pixels that don't need correcting.

This means that the attenuation factor needs to be taken into account, the ratio of incident radiation to radiation transmitted through a shielding material. Humid air acts as a “shield” for infrared radiation. dj 什麽意思WebbFor positive and colour negatives I find that the scanner's infrared dust removal does such a good job that my need for manual dust-spotting in post is very limited indeed. In fact, if there is so much gunk on the (non-B&W) negative that Lightroom can't deal with it after this one really should physically clean the film and re-scan. – dj 交換針
