Not sure what the question really is here. Are you looking to shoot
flowers on a black background in your house?

Nope, at home is easy.


You know that you really just need for your subject to be a few stops
brighter than your background (about 4.5 I think) and your background
will be black. You can shoot your flowers using flash on a table where
the "background" is through a doorway into a dark hallway or similar and
you'll get the effect of a completely black background. This is
especially true if you keep a smallish aperture, like f5.6-f8.

Yup, it's easy to do at home.  Just use flash indoors, or shoot at night.

I'd like something for when I'm out on a walk and want to get that sort of shot without having to cut off the flower.




I suspect you'll get no satisfaction from your "dark tent". If you setup
a flat black painted surface anywhere near your subject and any of your
light spills onto it, your background will show up as some shade of grey.

That's why I was talking about setting up a "porta cave". Aim it so that the light isn't shining directly into it.

If I'm honest with myself it's probably more a case of a solution in search of a problem. I had this "great idea" that's probably more intriguing to me than the actual photos would be.
