APERTURE IN CAMERAS AND LENSES.(post no.207)

APERTURES IN UR HAND.....While dealing with ur camera and making it ready to shoot pictures....the knowlwdge of Apertures is essential.....what the camera is producing thru which means.......Above are the APERTURES (holes) in the camera, which are operated in combination with Shutter Speed and made of steel blades....

Top is the largest aperture the modern cameras have or old lenses had. i.e.f1.2, next the light passing capacity is reduced and the light will pass thru aperture f1.4, half of the above aperture...so the number is increasing and the aperture is reducing......as:
                                                                           f2.8
                                                                           f3.5
                                                                           f5.6
                                                                           f8
                                                                           f11 and more.....as
                                                                           f16
                                                                           f32
                                                                           f64.......THEY DEPENDING OF THEIR USE on Shutter Speed and the ISO speed on camera as per the lighting available..............next Shutter speed.......continue.
