HELP__645N and AF360 flash

photofreek · 02-28-2011, 03:29 PM

I have just purchased a AF360 to use on my 645N, the only thing that I cannot figure out is the sync mode. I use manual focus lenses so are they --leading shutter curtain or trailing shutter curtain?

It does not depend on the lens. It has to do with the flash.

Leading curtain sync is the default. Flash fires as soon as the leading curtain has completed its travel. At slow shutter speeds, the flash fires and then movement is recorded.

Trailing curtain sync is an option. Flash fires immediately before the trailing curtain begins to travel. At slow shutter speeds, movement is recorded and then the flash fires.

Shutter speed should be slower than the sync flash sync speed.

Regards

I am going to be taking shots inside of a church, what is the most used technique, the leading or trailing.

If you are taking the photos during the day with relatively static subject matter trailing curtain synch with a slower shutter speed would be preferable. However, at night I would just stick at the 1/60th synch speed.

I would recommend using leading curtain in all situations except when working with moving subjects.

Around here it's not very popular to use flash inside churches, but I guess tripods are not very popular either.

I have done alot of research and have found out that 98% use leading curtain. I am taking piks in a dark church and the flash sync on the 645N is 1/60 and my fastest f stop is F4.5. I was told to use 400 film. The ceilings are 50' tall so I cannot bounce flash, so I will have to point it right at the subject, how can I balance the flash with the low ambient, or will the TTL take care of that?

Let us know how you do with the church. I have wanted to do that for years at Duke Chapel in Durham, nc, has towering ceilings, etc, but had no clue other than a really long time exposure.

I have taken the shots with an A 80-160manual focus lens and it turned out great except for a few piks where it was so dim that I thought I had the focus , but it was off just a little. I wonder if an FA 80-160 would work better, would the AF hunt in low light?
