Just in case anyone suffers like I did today!

My old Pi Noir takes "-fp" on the command line for raspistill to preview the image. That's Camera 1.

My new Camera 2, the latest one from Sony, gives a black screen with that option. To preview a still image, you just need "-f" instead.

The difference drove me nuts today - until I read the help! A time lapse script worked with the Noir but not with the new camera. I've fixed it now, so this post is just in case anyone else has the same problem.

Have fun.
