How to Calculate Crop Factor, F-Stops, and Equivalent Lenses in Google. DPReview did something in their RX100 Preview that I haven't seen before from a major review site although a number of us have been doing it for quite a while now.
They expressed both the focal length range as well as the relative aperture (f-number) range of various cameras in 135 format (35mm format) equivalent terms. For example, they list the 10-37mm f/1.8-4.9 lens on the Sony RX100 as equivalent in terms of angle of view and depth of field control to a 28-100mm f/4.9-13.4 lens for 135 format. Some also extend this idea of equivalence to include signal/noise, meaning that the RX100 would offer the same noise performance characteristics as a 135 format camera with a 28-100mm f/4.9-13.4 lens if that 135 format camera had the same sensor technology as the RX100.As time goes on, we have more and more formats to compare. Understanding Dynamic Range in Digital Photography.
Dynamic range in photography describes the ratio between the maximum and minimum measurable light intensities (white and black, respectively).
In the real world, one never encounters true white or black — only varying degrees of light source intensity and subject reflectivity. Therefore the concept of dynamic range becomes more complicated, and depends on whether you are describing a capture device (such as a camera or scanner), a display device (such as a print or computer display), or the subject itself. Just as with color management, each device within the above imaging chain has their own dynamic range. In prints and computer displays, nothing can become brighter than paper white or a maximum intensity pixel, respectively. In fact, another device not shown above is our eyes, which also have their own dynamic range. Strong Reflections Uneven Incident Light Accurate measurement of light intensity, or luminance, is therefore critical when assessing dynamic range. 2013 NAB Show: Digital Media Industry Event for Video, Audio, Film & Communications Professionals.

RE:Vision Effects, Inc. : Products: Twixtor. Twixtor® intelligently slows down and speeds up your image sequences.
Twixtor raises the bar in motion estimation. Twixtor is much more accurate, tracks objects farther, and exhibits fewer artifacts when there are objects crossing in the scene. This means less tearing and stretching of objects as they cross or go out of the frame. Twixtor enables you to speed up, slow down or frame rate convert1 your image sequences with visually stunning results. In order to achieve its unparalleled image quality, Twixtor synthesizes unique new frames by warping and interpolating frames of the original sequence... employing RE:Vision's proprietary tracking technology that calculates motion for each individual pixel.
Nick Brooks, Academy Award and Emmy Award winner for visual effects says, "Twixtor represents a new touchstone in retiming. Smoke - Professional Video Editing Software for Mac.
