f.8 1/125
f.8 1/250
f.8 1/30
*the number of shutter speed start from B ( manual shutter using) to ---- 1/5000 sec
we use shutter speed number to cash a speed shoots .. like here
f.2.8 1/400
f.4 1/500
f.2.8 1/500
*there is an a relashenship between sutter speed and Aperture and this called EV
Her we us an other case of shoots .. the camera slow shutter and th object is ďŹ xed
f.22 1/2
f.22 1/4
*In this case we use Aperture like 16-22-32 , As , if lights take a lot of time the photo will be over expouser
Exposure Value (EV)... indebended on shutter speed and Aperture .
shutter speed
1/1000 1/500 1/250 1/125 1/60 1/30 1/15 1/8 1/4
Aperture
f/1.4 f/2 f/2.8 f/4 f/5.6 f/8 f/11 f/16 f/22
If your meter read f/1.4 .. 1/1000 then you can use f/22 ... 1/4 and you will get same resulet but the defrance will be in deepth of filed
*Deepth of filed depend on Aperture so, if you want to small deepth of file use low shutter speed and hight f.stop number
f.2.8 1/125
f.16 1/125
