THANKS for the EXPLANATION ABOUT the REGIME of the CANON 1000 d CAMERA IV CFn

Hi doctors!
I'm very perplexed newborn photography ideas the focus and metering techniques with my canon
EOS 1000 d. Has your doctor would have taken days for I'm a bit more experienced.
By the way translated into Vietnamese and explain for me this installation mode:
CFn IV OPERATION/OTHERS SHUTTER/AE LOCK BUTTON
O: AF/AE lock
1: AE lock/AF
2: AF/AF lock, no AE lock
3. the AE/AF, no AE lock
Has your doctor would advise households should put on? Normal shutter button at the same time as the launch button stroke soup mechanism (basically calling focus). When half-pressing the shutter button mechanism to guard its operations, complete your blink green light, have the beep to know and push forward to capture
With some situations, separate shutter button and button Align stroke is necessary. Therefore Canon invented button to focus exclusively on the back and can be setup for this multi-family by Cn IV as your doctor says. in the set on the front one is the job of the shutter button, the back button is the one stroke soup (with rosette, rear air).


For example, setup 0 (default): is the AF/AE lock, i.e. the shutter button and the button stroke soup, while the United States is the button a button AE lock. Setup 1: AE lock lock/AF: at the moment the shutter button only do AE lock, did guard a flower button strokes
So when you press Fn then 1 IV chon half shutter button, the machine is not in focus, which hit the next to take the setback as the machine will not focus, blurry photos or lucky unidentified bad. You must use your thumb to press the button to a blossoms strokes, while the index finger pressing the shutter button to shoot. Some medical doctors say is always measured in the morning. Custom this fuction to assign function AE lock (lock metering) asterisk button or shutter button in the back of the machine, rather than talking about the metering function assignment to buttons. If you select 1, the asterisk button to autofocus (AF), the shutter button to lock metering (at 1/India). So the capture would be the thumb button to a blossoms, soup sounds bip to affirm its OK, then your thumb push the shutter button. If you want to lock the metering then I press 1/2 shutter button. (you can work before, it would also be, since the two things separately)
I just remember previous letter, IV Fn dash is to assign functions to buttons in the front (the shutter button), the word behind the dash is to assign functions to buttons behind (a flower button).

This invention of the Canon is very useful for the lock metering without fear of false strokes by moving air. If the shutter button at the same time as pressing the AF button for 1/2 and hold the air has just locked the metering, just lock the strokes. When you move the machine to the layout, the photos probably were out strokes due to the change in distance (because moving air when Thermo). If you separate the two jobs (autofocus and metering separately) then you can lock metering, Thermo press the focus button to a blossoms.
 
Finishing Other benefits or are mentioning that when I capture multiple panels that the distance between us with the subject was taken does not change, we just need to focus once (if not detached two functions then just press the shutter button half each time, your back stroke soup again, taking the plate 10 focus 10 times, takes more time). For example when you take Obama standing, if want to snatch the best moments, the physician must hold 1/2 shutter button, and then, when seeing the beautiful next-> inconvenient. With the photography gift ideas , you can assign to a blossoms button soup. Doctor stroke soup then down down, see beautiful moments, then lift the machine up shooting right away (without having to press the 1/2 shutter button, because at the moment my focus is gone)-> very quickly (on the condition that the distance from your doctor to Obama does not change it).
