How I can have an exhibition of more than 30 seconds on a nikon d7000?
I can put it on bulb mode, but I have to hold the shutter button. There must be an easier way
Get a remote control as the Nikon ML-L3. They cost about $ 15. Put the camera in manual mode, set the aperture, focus, and ISO. Then set the remote release mode (or remote time) and then what 'bulb' would have been. This setting is now called "Time." Press the remote button once to open the door, and once to close. With the remote, you can take long exposure photos at shutter speeds up to 30 minutes. Make sure that the noise reduction rate long shutter is activated, this may prevent the edge pixels and hot purple fringing that can occur. Unfortunately, it has another 30 minutes to process.
