I have often read of how wonderful back-button focusing is and how it forever changes your photographic life for the better; so, I decided to read up on it and give it a try.
I Googled "how to back-button focus and thoroughly read the ten or so most promising looking tutorials.
Interestingly, we have at least five thick specific T3 how-to books and I could not find a single mention nor explanation in any of them.
I took an even fifty practice shots and I must surely be doing something wrong.
I have always had only the single center focus point active.
From what I gathered from my online reading, I went into Menu>"custom functions"C.Fn.IV and went to number 7 in the little window; I scrolled down to 1:AE lock/AF and pressed "set"; 1:AE lock/AF became blue with the other three choices remaining white.
Although I can see no indication of the fact on the LCD shooting screen, according to what I read, I should have enabled back-button focusing.
It is my understanding that the * button is now my back-button focus.
I left my focus choice on "one shot"; is this the correct choice ?
Now, this is where I get lost:
With my T3 set up for back-button focus, what should be my sequence of events ?
Does half-press shutter-button STILL set focus and I then, once focus is achieved, hold the * button to keep focus locked in; or, does the shutter-button no longer activate focus and the * button now activate focus instead ?
I hope I worded my questions in a way that they make sense.
Thanks for reading.
