Straight on the money with my problems too.That explains why I see TTL BL in the EXIF data with the flash raised. I understood about spot metering and set matrix metering expecting to see the option available, which you explained is a misunderstanding on my part. I have selected the option to NOT automatically popup the flash when the camera thinks it needs to, but I would still expect the front curtain default when I raise the flash manually.I tried an equally challenging shot from indoors with an an open patio door in the center of the scene. Leaving the matrix metering and flash to work it out I got poor results. Then I exposed the same shot with no popup flash metering for outdoors, previewed the result and as expected outdoors was correct (metering worked as expected), indoors was under exposed. I switched to manual flash and re shot the same scene several times with increasing increments of flash power. At around 1/20 flash power, indoors was nicely exposed whilst outdoors remained exposed correctly. Perhaps I was expecting too much for the camera to work out this type of scene? I will repeat what I did again, go back and look at the exposure data. If it stays the same flash up or down and only the flash power is changing, then I will be happy camera flash is not modifying metering. If the exposure is changing then I will remain puzzled because I still haven't understood how the camera knows how to throw lots of flash light for a dark indoor shot, yet only a small amount for a short range subject dimly lit with daylight behind.Correct, I tried that and as you say, +1 is insufficient.I've got the Meke MK910 I can try.Thanks for the link.Perhaps I'm thinking to simply, but when I am standing 2 metres behind a dark brick arch looking through at a good daylight scene, I know the popup flash can light the brickwork. Perhaps in practice the camera cannot 'automatically' expose this correctly because it cannot differentiate between the high brightness daylight it meters and any pre-flash light bounced back. Which is why manually setting the flash power although requiring more test shots, can be made to work. I shall spend more time reviewing my test shot EXIF data because that will tell me if the flash is being fired, at what power level and whether exposure compared to flash 'off' is being modified. </blockquote>
