Hello Krishnan,

I think you advice to hamid may be incorrect. First, the Speedlite 580ex is made by Canon. It may be more appropriate to reccomend a Nikon SB900.

Secondly, ISO 1600 on a D70? On a D700 OK, but for D70 there is a lot of noise at ISO800 and ISO1600 would be much worse.

I’d recommend, with a flash and tripod to take the following steps. (I’m assuming your subject is a person against a night time cityscape.
1/ Set the camera on a tripod
2/ Set aperture to f11 (this i agree )
3/ use spot metering. Choose a spot on the background and adjust your shutter speed to that your exposure meter indicates that the background will be exposed properly. Recompose your shot (You can forget about the meter now)
4/have your flash on the camera. Personally I like manual mode. Set the power to 1/32 or 1/16 or so.
5/Take the photo. The background should be fine. If your subject is too dark, open your aperature more, like f8 or f5.6. If your subject is too bright, close the aperature more, like f11 or f16.

Keep in mind the distance between you (and your flash) to your subject. The farther way, the darker the subject will be…

Cheers!

You’re just peddling basic info, a 20 dollar book will say the same things you claim to be “secrets”. Although I commend you, im sure your words have convinced the same people who think megapixels matter, to shell out hundreds for dribble.

Hello Hamid,

Lighting is not a problem. u can use a SppeedLite 580X for a better lighting. Set your camera to ISO1600 if it is for night shot. and to achieve a sharp image use F11 with a lower shutter speed. Use AV setting it will be very appropriate.

ISO is once area you can manipulate. view my photos then you will know how to take night photos. I normally use manual and set a low speed in dark areas shutter speed 1/50, F11, ISO 1600
This is sufficient for various shots including Formula One sports at night.
All this I learnt from David only. Just sharing the knowledge with you guys.
