Night Time Gambling
Image by Lenny K Photography
Here’s a photo that I’ve been meaning to share with you but only got to processing it today. Its a picture of Brisbane’s casino across the water from South Bank in which the camera settings used were f/11, ISO 100 with a 10 second exposure time, 85mm Nikon prime lens.
In publishing this photo I wanted to introduce the handy ISO 6400 rule which can be useful your night time photography.
This rule helps you quickly determine our exposure by letting us know that 1 second @ ISO 6400 = 1 minute @ ISO 100.
What this means is that if you set your camera to Manual mode + set ISO to 6400, with Aperture X, 1 second Shutter Speed and take the photo, the exposure of your photo will be the same as if you had taken it with ISO 100, with the same Aperture X but a 1 minute Shutter Speed.
We can then do a calculation to find out how much exposure time we need for a photo at ISO 100 or 200 or 800 etc.
You may ask why this is useful? Here’s the answer:
You may want to preview what a photo will look like at ISO 100 for those crazy 10 minute photos (stars, water, clouds can crazy things @ this exposure!) but not want to wait the whole 10 minutes and not want to shoot at a high ISO. In applying this rule you can set your ISO to 6400 and just take a 10 second photo to pop out this preview of how this photo would look at ISO 100 for 10 minutes. Or you could also use this rule to calculate that at ISO 200 you’d need a 5 minute time a photo that has this same exposure.
I hope this tip has helped you out, if you’ve got any questions about it drop me a message and let me know 🙂
