The Société française de photographie, founded on 15 November 1854, was based on the short-lived Société héliographique (1851) but differed in that it was less elitist and more forward-looking. Some accounts mistakenly link the two organizations more closely, referring simply to a change in the name with a view to giving the SFP the ...
Peak-to-peak amplitude (abbreviated p–p or PtP or PtoP) is the change between peak (highest amplitude value) and trough (lowest amplitude value, which can be negative). With appropriate circuitry, peak-to-peak amplitudes of electric oscillations can be measured by meters or by viewing the waveform on an oscilloscope .
Every year, the AFC hosts the Journées AFC de la Postproduction; The AFC participates in the Cannes Film Festival, and organizes professional events on an international scale at its stand, the Pavillon de l'Image. The AFC publishes original interviews granted by cinematographers whose films have been selected by the Festival.

Depending on context, wave height may be defined in different ways: For a sine wave, the wave height H is twice the amplitude (i.e., the peak-to-peak amplitude): [1] =.; For a periodic wave, it is simply the difference between the maximum and minimum of the surface elevation z = η(x – c p t): [1] = {()} {()}, with c p the phase speed (or propagation speed) of the wave.
The Centre national du cinéma et de l'image animée (French pronunciation: [sɑ̃tʁ nɑsjɔnal dy sinema e də limaʒ anime]; CNC; transl. National Centre for Cinema and the Moving Image) is an agency of the French Ministry of Culture, and is responsible for the production and promotion of cinematic and audiovisual arts in France.
The reason IRE is a relative measurement (percent) is because a video signal may be any amplitude. This unit is used in the ITU recommendations BT.470 and BT.1700 which define PAL, NTSC and SECAM: [7] [8] [9]
Amplitude is a measure of a periodic variable in classical physics. Amplitude may also refer to: In mathematics and physics. Jacobi amplitude of Jacobi ...
