It´s incredible how Super 8 can offer compared to standard video systems.

These pictures looks like 1970´s still photos from small formats like 110 or 126...

Great work, Fred!

sort of. it "flattens" the gamma curve, thus fighting the cumulative effect of using two gamma transfer functions to produce the image, first the film then the video camera. a scanner should preferably use a flat or even log curve since the original is already compressed to a viewing gamma. but to use the words of my arch enemy: what's gone is gone.

OK:

I take this very serious.
Not to start a new battle or something, just to be sure and to learn.

Here is the histogram of one of the frames:
I see a peak in the shadows, the mid parts and the highlights (green), but enough in the mid parts, so this is not a 'flat' histogram at all.

Here's another one:
Here I see a huge peak in the shadows.

And this is the histogram from Thomas, the same frame, but taken with his 3CCd Sony and the workprinter. As you all see, his histogram is better, but he also has this same peak in the shadows.

Image

I did more tests, and the conclusion was: for K40 I must set contrast of my capture camera at the lowest possible. Then my result comes very near to the result of this wonderful 3CCD Sony camera. But the Sony is better, of cource. (If you look at the price, it better should be... :P )

Another conclusion is: It depends not only on the stock, but also on the scene... Sometimes I have perfect results with '60's Agfa, sometimes bad results with brandnew K40. And vice versa.

Fred, the big skinny peak you see in the shadow portion of the histogram is the frame line. You can see the fatter peak in the Sony cam histogram because the frame line is fatter in that image.
