Trombone music, along with music for euphonium and tuba, is typically written in concert pitch in either bass or tenor clef, although exceptions do occur, notably in almost all brass-band music where tenor trombone is presented as a Bâ­ transposing instrument, written in treble clef.
Basic Manual settings for cool visual effects. A Little About Exposure: Exposure is the amount of light a digital camera's sensor captures when a photo is taken. Too much light results in a washed out photo (overexposed). Too little light and the photo will be too dark (underexposed).
In photography, exposure value (EV) is a number that represents a combination of a camera 's shutter speed and f-number, such that all combinations that yield the same exposure have the same EV value (for any fixed scene luminance).he exposure values in Table 2 are for ISO 100 speed (EV 100 ). For a different ISO speed, increase the exposure values (decrease the exposures) by the number of exposure steps by which that speed is greater than ISO 100, formally.
