Hi Adam, On most digital cameras, slow-sync has two effects. First, it makes.
The flash fire at the end of the exposure. That effect you cannot simulate without activating that setting, but it only matters for.
Slow exposures with movement (1/4s or longer). The second effect.
Is that it lets the camera chose a slow shutter-speed rather than.
One where you would be able to take the pictures hand held. This.
Effect can be copied by using manual exposure and manual flash.
Control. Many advanced cameras have this feature, I do not remember.
If the FZ5 has it though. Hope this helps, - Itai.
Thanks, Itai. I understand. And the camera does have manual exposure, and also "flash exposure compensation" (I'm not sure if this is exactly the same as "manual flash control", but I assume it's at least similar). I have the feeling, though, that it is really difficult to learn which settings to use in a given situation. Is that right? Also I wonder if you need extra equipment (like a light meter, or something) in addition to the camera?..
Hi Adam, "Flash exposure compensation" is to "manual flash control" what "exposure compensation" is to "program exposure". Basically, it allows you to tell the camera to make it's calculations and then adjust the result plus or minus some. The big secret is that in manual mode, the camera doesn't do any calculations so that function becomes similar to "flash control". The same with Auto ISO, in manual mode it becomes fixed ISO on most cameras. You can learn more about exposure compensationa at: http://www.neocamera.com/feature_exposure_compensation.html As for learning the correct exposure, the difficulty is that the "right" setting depends on the situation AND the desired outcome. The Program modes does the general exposure rule depending on it's metering mode.
All modern cameras include a reflected light meter. You can use an external one too, but no one will say that you "need" it. - Itai..
Itai, thanks for the link to the webpage. It's very interesting. I think I will be happy if I can just figure out how to take a "general" slow sync exposure (just keep the shutter open a little longer than normally would be the case for a flash picture). For now I don't need to get creative. The problem is that the "pre-programmed" slow sync includes a red-eye pre-flash. And I find this pre-flash makes a lot more trouble than it solves.
Adam p.s. Yes, thanks. I guess cameras has an internal light meter. But, does this help us when using manual mode? Does the camera report (display) the light reading? I didn't think so (I thought the cameras use the light meter to calculate exposure (though it never can report the data on light to us...
Hi again Adam, From my understanding, what you need is to go into shutter-priority mode, select the slow shutter you want and enable the flash (without the red-eye, that means no slow-sync in your case). You can dial the flash power down using "flash exposure compensation". The effect is that you will get a flash at the beggining of the exposure rather than at the end (as you would get with slow sync). As long as there is no motion in the scene, the results will be the same. If there is motion then, light trails will appear ahad of the moving object rather than behind. As for manual exposure, the way most cameras report the reading is with an offset indicator.
Other cameras simply change the color of the aperture/shutter setting. Some cameras unfortunately don't do any of this. Hope this helps, - Itai..
Many, many thanks, Itai. I think I understand, in principle, what to do now. I'm just now sure how to chose exactly WHAT value to use in any particular case. But, I'll just have to practise and try and figure it out. Well, I bought my Panasonic camera today, so I start my practise right now Thanks again for your wonderful help. You're aces...
I have a Canon A530. In your review, you mention using a "slow-sync" flash mode for improved flash performance. I can find no mention of such a setting in the documentation or in the camera settings. Could you please explain your usage of this term and how I would select this mode...
