Yesterday’s Topic: Quick Exposure Adjustments
Short and to the point, to help stop blur in a photo because you are moving the camera too much, use this formula:
This simple formula comes into use when you are hand-holding a camera. Those using a tripod can throw this out the window.
In practice it looks like this:
- 18mm lens = No slower than 1/18th of a second
- 50mm lens = No slower than 1/50th of a second
- 300mm lens = No slower than 1/300th of a second
And so on.
This applies to full frame or ‘cropped’ sensor cameras. 4/3rds too.
As you might guess, most cameras don’t come with a 1/18th second of a shutter speed. For the most part, round down to the next fastest shutter speed (=higher denominator = larger number in your view finder). So that 1/18th can be rounded to 1/20th, just to be safe. The faster you go, the less blur you will cause just by the fact that you are a human and have blood coursing through your veins and a silly, constant need to breathe. Breathing and holding a camera properly are important and will tip the odds in your favor.
