This question already has an answer here:
Unfortunately, I think I already know the answer to this but I'm hoping I'm just missing a trick:
On a sunny day, is it possible to compensate for a 2 second shutter speed so the photo doesn't come out completely white?
When I was out yesterday, I set my camera to f/29 ISO 100 (the lowest I could go) to try to get a slow shutter speed photo of a river. The problem was, though, the sun came out and I ended up with several areas of the photo that were overexposed beyond repair. In manual mode, the exposure compensation feature on my camera does nothing. Is there a way to prevent the whiteout or am I just out of luck?
Also, would it be better to take the slow shutter photo, take a quick duplicate using aperture priority, and then compile the two?
Any suggestions are greatly appreciated. Btw, I'm using a Nikon D5600.
