Instead, the longest allowable shutter speed tends to be around 30 seconds, although it does depend upon your camera. Long-exposure, time-exposure, or slow-shutter photography involves using a long-duration shutter speed to sharply capture the stationary elements of images while blurring, smearing, or obscuring the moving … Once the photographer has determined the exposure, aperture stops can be traded for halvings or doublings of speed, within limits.

Digital capture tends to be more tolerant of underexposure, allowing better recovery of shadow detail, than same-ISO negative print film. On most lenses, f/4, f/5.6, and f/8 are three of the sharpest apertures. Also, after you’ve taken a picture in the field, review it and see if there is any blur when you zoom in. And now of course, everyone’s favourite long exposure technique – light trails! A large aperture lets in more light. So, what shutter speed should you use? Instead, getting the proper exposure for a photo is about balancing those three settings so the rest of the photo looks good, from depth of field to sharpness.

If your subject is standing still, or only moving very slowly, you can get away with a longer shutter speed. So, as one gets more comfortable with the elements impacting exposure, I would add the amount of glass between the subject and the sensor as one more.
