They are not the same because its Negative and not Positive (or Slide film).

This actually represents the full amount of information recorded on the film for each channel. You might notice that there are quite similar shapes to each of them and all three have a similar peak at the brightest end. If I cycle through the Red Green and Blue for this particular negative I get the following: Now that doesn't mean that it records less information, just that it records it over a smaller range of density changes. Notice how much of the selected preview image is bunched up over to the left? Well that's because the blue channel has the shortest range in ability to record the scene. Now heres where we do the important thing, go to your histogram control and select (as a start) the blue channel. Now if you set your scanner to positive and preview I'm sure that it'll look just like the image to the left.

So lets load a negative into our film holder and take a look at it. Just give this a tweak one way or another to align the border. Under Scanner Extras you you will find the boundary offset adjustment slider. This can happen anyway with particularly dark strips of slides anyway (like shots of the night sky) so its well to know this trick anyway.

This brings us to the first problem that you will encounter, when using the SA-21 the software trying to scan Negative as Positive the stupid software will not properly sense the boundaries between the negatives.

Surprisingly its not hard, so here goes my attempt at conferring a trade secret to you guys.

Scanning negative film is (apparently) not a straight forward thing, and perhaps its hindered by the (lack of) understanding of the media as much as the software that is supplied.įor quite some time people have debated back and forward about which way is the best to remove the orange mask in Negative film and which software works best.
