Slow Sync Flash

[NewbieD70]

Does anyone know the settings in the D70 for the slow sync flash option? I have searched the forum to no avail. When I look at the flash settings it has 3 choices, but not sure which one. I was looking at this tutorial and wouldnt mind giving it a go

If your explorer gives you an error looking at the link, go to the main site and click into the section from there.

Thanks Trevor

well trev,


there isnt a 'slow sync flash' option on your d70, at least as far as im aware. you will need to dial the settings in (more or less) manually.

just flick over to manual, dial in a slower shutter speed, and pop the flash. experiment a little bit. it wont take long and you will get effects similar to what is on that page.

if you hold down the flash button and swivel through one of the command dials, you should be able to find a setting on the LCD that says 'R' or 'Rear'. That will give you a rear curtain flash - ie the flash is fired at the end of the exposure.

i havent shot this type of photography in quite long time now. i find that it is useful, for say a portrait, but needs to be used in moderation... it gets tired quickly, imho.

it can be useful if you have limited lighting options, however.

i apologise for the vague nature of my descriptions... as i said, havent used this type of photography in a long time, but the general gist is just to run a longer shutter speed, perhaps tighten up the aperature (bigger f numbers), and use a rear curtain flash.

i might add that this type of photography is very fashionable/trendy at the moment for live bands...

I think there is ...

And, for at least one of your camera modes (A/P/S/M) as you traverse the options James has described, I think you'll also flush out a "slow".

I've seen it, but I've not touched the 70 in a month or so.

actually your right, i too remember having seen the 'slow' option... somewhere... can't remember where.

nonetheless, if you shoot manual, you'll probably find it more effective just using a slower shutter speed and a rear curtain sync.

From memory, if you go into the menu you will find a minimum shutter speed that you can use with the flash.... crank this down as low it will go. Exit the menu and then hold down the Flash control button to the side of the lens mount and select the slow setting. About this time if you set the camera to either P, A or S mode you should get slow sync, providing you are in low enough light conditions.

The other option is simply to do it as the pros do it...
Set the camera to M for Madness (or manual, methodical, mystical... etc).
Set a slower shutter speed, relevant to the amount of light about and the subject you are photographing. (note, its a waste of time trying to attempt slow sync in daylight conditions)
Set and aperture that is going to underexpose the background a couple of stops (so that any brightness from the ambient light does not compound on the flash exposure)
Test the exposure without a flash if necessary
Turn on the flash and proceed to make photos, either in TTL mode or Manual mode.

REMEMBER... if you select a smaller aperture you also reduce the effective range of the flash. If you want to increase the range of the flash by double the distance you will need to open up the aperture two whole stops (i.e. from f11 to f5.6). In doing so (and to maintain the same ambient exposure entering the camera) you will need to speed up the shutter two whole stops.

hope this is a help!

Thanks everyone, much appreciated...now to go and have a tinker !

As per above, CSM menu # 21 on D70, set it low as 1" or even 30". I have mine always on 30" just because I'm lazy...

"SLOW" sync mode is available on A and P modes, they are not available on S or M modes. I never tried it so I don't know what is the difference between this and the rear sync...

I hope this helps...

"SLOW" sync mode is available on A and P modes, they are not available on S or M modes.

The whole idea of slow sync is that you use a slow shutter speed to capture ambient light and movement. What better way to get the camera shooting at a slow shutter speed than to use the S (shutter priority) and M (manual mode)... in fact it is easier and more reliable in these modes.

If you are going use the Aperture priority or the Program mode to experiment with slow sync then you are in fact letting the camera make all the decisions for you... not a good plan.
