Why are my photos white when I do a long-exposure?
The problem is that you have too much light entering your camera so your photo is becoming over-exposed. To solve this you need to let less light in, and there are five ways you can do this:
- Stop down your aperture (if possible)
- Reduce your shutter speed
- Lower your ISO (if possible)
- Put a filter over your lens (ND or CPL)
- Wait for the ambient light levels to drop, like during dusk or dawn
