I would now narrow the middle section of the blue curve rather than increasing the slope. The settings for bright colors at the top right of the curves might not be so symmetric as I assumed above, since bright colors depend more on the transparency of the slides than on the faded dyes that count for dark colors.
This film and slide scanner beats out the device I bought by Wolverine Tech that snaps a digital picture of my negatives and slides. The Canoscan FS 2710 has no vignetting and no ill considered custom color curve that must be undone in post processing.
I posted two articles at the viXra archive for physics outsiders. Have a look if you will. I try to post first drafts of fresh thinking here, though. And look for my book "Hacking Physics".
http://vixra.org/abs/1211.0139 is my article "Neglect of General Covariance".
http://vixra.org/abs/1212.0094 is "Draw the metric!".

Think about it in a careful way. Visualize a spacelike line, then extend it as a geodesic. Using a proper diagram of the universe, it is easy to show that this eventually intersects the big bang horizon. Don't be confused by convention; the Friedmann coordinates are very deceptive.
So shards of the big bang, expanding at light speed from a universal starting point in the past, are essentially contemporaneous with us.
I read his essays on this point but did not understand until this year. He knew that natural selection on groups was a truism. And so he did not even argue at length for it, only focusing on the selection that acts on various sizes of groups, as opposed to accidents of history.
So now I will probably use the ST65 at ISO 200, -1 contrast and +1 saturation. The pixel noise might be tolerable for down mixing to 2 million pixels and posting at Google+.
UFRaw does use a white level and balance that are set from the camera and the color matrix. In fact the photographic levels are truncated to the white level as given. So my expectation of being able to recover the highlights from an overexposed subject is frustrated. But just click the button to get the white balance from the camera. And set the camera's notion of the exposure by putting the flat truncation to the top of the graph using the exposure slider.
I see that the ST65 overexposes in order to suppress noise. ISO 200 is actually ISO 80. This causes the high contrast naturally. I wonder if custom color curves in RawTherapee together with the low contrast setting on the ST65 can result in highlight recovery, while still taking advantage of the noise reduction from overexposure.
My Samsung ST65 camera actually has a contrast control, and I have now realized that the proper setting for it is not zero. The default setting enhances contrast in the shadows and compresses the highlights. A -2 setting for contrast balanced by a +2 setting for saturation improves the appearance of the gray scale on a picture of the Color Checker 24 card. This might not be the final word - I will look at -1, +1 as well; but I have no desire to do post processing on photographs from this came
For film cameras using the same film, the bit rate proportionality simplifies to the product of the aperture area and the frame area. Slower film has the higher bit rate. For digital cameras that use the same technology, the proportionality is to the product of the aperture area and the number of pixels. But smaller sensor areas can force you to take multiple exposures in order to complete the picture with the required signal to noise ratio.

Study of natural selection on groups is the most thorough rejoinder to to the libertarian dogma. Natural selection on groups is actually a mathematical truism. And it has a proportionate practical effect whenever transactions between individuals are not zero sum. The prominent effect is to promote specialization of individuals. Witness all of the specialties in the groups called ecosystems. The deprecation of groups by promotion of the concept of individuals is mathematically only a false dic
I am very interested in the question of what kind of digital camera can match the quality of a 35mm film camera. In the context of the new high definition digital post processing, how many pictures with a standard information content can I take with a camera in one second of open shutter?
Cosmologists need to check their work by using different coordinates. The Friedmann coordinates conventionally used are rife with fictitious potentials which interact nonlinearly with real sources of gravity. It is Cartesian coordinates alone that have no such effects. And hyperspherical coordinates are still orthogonal everywhere, so they have no off-diagonal fictitious potentials.
