    any good website delicated to teaching or write up on canon system pop up flash...

    the problem i face is if i use P, i need to reduce power of the flash... i use m, need to trial 1 shot minimum... need to memorise the distance, etc...

    but i never try auto yet...

    Isn't pop-up flash E-TTL? You don't have to set any flash power what.

    ya, it is... but then, most of the time the pic is over expose at P setting... but now after reading at least i know min distance is 1m away... and that P mode is always 1/60 to 1/200... but without - the flash output.. still over expose.. i will need to try the 1m, or remember the position, + the - flash output with M mode... flash = troublesome... but some scene really need flash lor... cos too dark.. anyway, i will try again during the next opportunity... thks for reading...

    oh ya, i read from the link tat ef28mm doesnt return distance... meaning the E-TTL doesnt work?

    From my very limited experience, ETTL tends to use too much flash power, so the background is dark and the subject is too bright. I normally leave my pop-up flash on -1EV for portraits, so the flash isn't that obvious.

    i doing almost the same like u, force the flash into minus territory, by 1 click for me.. not sure if it is -1EV or not...

    The ETTL determines flash exposure by light intensity measured through the lens, and is independent of distance AFAIK.

    I think the return distance you are referring to is the ability of the flash to "zoom" it's output so that you don't waste light illuminating things outside your frame. Except for very few exceptions, the vast majority of pop-up flashes do not have this feature.

    "one click" depends on your camera model and settings. Could be 1/3EV or 1/2EV.

    Oh and I leave a small piece of 1/4CTO on the pop up flash. Help makes the output warmer and less harsh.

    CTO = colour temperature orange. It's basically a piece of orange plastic, something like cellophane (but tougher), which is called "gel" for some arcane reason.

    It comes in different intensities, 1/4, 1/2, 1. For normal use, I find 1/4 to be sufficient to give a nice warm cast to the subject. I'm sure the pro-bros around here will tell you more..
