Light trail and long exposure photography

[faustdownunder]

Found DigiCamControl yesterday and really like it. I use it with a Nikon D5500. One of my interests is daytime light trail photography and long exposure photography. I find that ISO 100 is usually still too much sensitivity. I wonder if the sensitivity can be reduced for very long exposure times ?

thanks

Hello
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 elements, so set the property value which is supported by the camera.
Thanks
