Well Worn

***Dave*** · 10-11-2005, 16:48

Shot I took today to test "slow synch flash". Basically had a pair of old trainers (no sneering Jamey

) taking natural light from front door. Found the shot to look a bit flat, so added slow synch flash.

Tripod Mounted with 50mm f/1.8 lens
2 secs @ f13

Seems to work quite well interms of lifting a natural light shot , instead of a normal stark flash shot.

What are other people's use of this flash mode ?

was that with the integral flash? If so, it's very well exposed and no harsh shadows. I guess this is due to the slow sync (is that back or front curtain, I can never remember)

I think the only time I've used slow sync is at clubs and such. so as to get the person I'm photographing still and 'crazy' light trails in the background. Bit tacky but can work well sometimes. I've never really tried it for night portraits, which is how it's listed on most compacts.

Yep, just the integral flash. Was in "Slow" flash mode, although tried "slow back" curtain which fired twice...once at beginning & once at end (from memory). Not sure of the technicalities without referring to manual.

quite pleasant to look at, very well worn!

Well they were quite smart until I started to use them in the garden, then decorate & splash white paint on etc. etc..

Well worn?
Theyr'e better than my Sunday trainers :eyesup:

The shot would work better in smellyvision IMO

Slow sync is the way to go!

Slow flash Sync is great for indoor shots and groups at 'do's'

What normally happens is the flash is killed as soon as the subjects are properly exposed, which results in the room behind the subjects being pretty dark. If you set the exposure for the ambient room light this will give you a much slower shutter speed. Let the TTL flash handle the flash fill and you get far more evenly lit, natural looking shots - even better if you can bounce the flash.

Depending on how slow the shutter speed is you might just have to ask the subjects to keeps still, to avoid ghostly secondary images from the ambient light.

IIRC correctly, back curtain fires the start of the exposure and reults in the trails following the exposed subject, and front curtain does the opposite.

Sometimes thinking of these photographic theories and practises has a proportional effect to the result. i.e. the effort of thinking about them pushes my brain out of my ears. Think of a see saw if you can? A bit like I imagine telekinesis to be like!

You got it. But you can develop a serious headache thinking about it! :lol:

My insanely logical brain just seems to suggest it should work the other way around for some reason.

LOL I didn't read your post properly mate, it IS the other way round, your brain is standing you in good stead despite all that alcoholic abuse.

First or front curtain sync - the flash fires just after the first curtain has moved across and the shutter is fully open.

Second or back curtain sync - the flash fires just before the second curtain starts to close.

Ah. The dense fug is lifted. Mucho gracias!

CT · 10-11-2005, 23:25

And just to add to the confusion, nearly all focal plane shutters travel upwards now rather than across.

but there are still two of them. You will not defeat me with your simple Jedi Mind Tricks!

ROTFL! and those 'curtains' are now made from metal.

A couple of good example shots here...

Here's one for you 350 owners with an interest in the first curtain/second curtain thing.

I tried doing some sort of light trail in Steves car a few months ago (with the light trails outside, but the lit dash inside etc).

Set the custom function to Second Curtain flash...what does it do? Fires upon start of exposure, and at the end...?
First Curtain flash just fires it at the start?

Wierd.....

Bod, the flash only fires once whether you use first or second curtain sync.

The function is only really useful for shots where objects are passing across the field of view at right angles (more or less) to the camera.

Take this shot in which first curtain sync (normal) sync has been used.

Imagine the camera on a tripod and the girl with the sparkler running across at right angles from right to left. As she comes into shot and you fire the shutter, the first curtain opens, exposing the senso
