Option for preview before taking the real image.

[Vidhyanandcs]

A preview to adjust the settings automatically before taking the real images would have been a great functionality.
Does such functionality exist with this package?

Hi @Vidhyanandcs, thanks for the question. This functionality does not exist today, though it should be simple to implement. Likely the best way would be to add another option to StillCamera & StreamCanera for showPreview which forwards the --preview argument to raspistill/raspivid.

We would be happy to review a PR for this.
