How to fix 'press shutter release button again' error on my nikon dslr?

I encountered this error when I was using it for my toy photography. It always occurs whenever i want to focus on something small and little. A bit confusing like what cause it and how to solve it? I'm using nikon d3300

The toy needs to be within the focusing range of the lens.

Use Area Mode AF and make sure the focusing point is on the toy.

if you are using spot exposure then it may not be possible to get a correct exposure for the whole toy.

When you get closer to your "toy" than the lens is capable of focusing, the camera will NOT let you take the photo unless you are in the manual focus mode. If you do get a photo, it will be out of focus

You either need to buy a macro lens like the Nikkor 40 mm or some extension tubes which have electrical contacts so the camera can still talk to the lens

Buy a macro lens.

Have you set mirror lockup?
If so then disable it

3300. My photos are coming out very dark help
