Black background
Fired many shots. Didn't kill anything.

I shoot with 2 pieces of A1 black card from Hobbycraft as well as a sheet of black perspex . Always always lights off in the room so pitch black and careful placement of flash heads / or a daylight balanced continuous lighting LED panel and I find have virtually no detail / light on the backdrop card

The 50x40cm backing boards that camera clubs use for competitions are very useful as black backgrounds.The image I use of stamps to illustrate the closest possible focusing distance in lens reviews uses such a board. The stamps are stuck onto the board to make a handy, re-usable target.

The more I look, the more there is to see!
For macros, I use two sheets of card covered in black paper & hinged together with tape, With the hinge vertical & the sheets open to 45 degrees (ish),-I shoot in towards the r. hand side so the any reflection in that sheet is of the other sheet. If any light gets in over the top, I place a further black sheet on the top of the hinged pair. With the pair placed pointing towards the main (day)light, this works pretty well, with just a little adjustment in Elements 11, levels.

Thanks, a good tip.

The problem is however I set up my LED light on a desk tripod some of the light reflects off the background as well as highlighting its texture; I then spend more time in Lightroom getting rid of these reflections than anything else in the process. Moving the background further away would help and I tried that with a large sheet of black paper but it still had a somewhat reflective surface which caught light bouncing off the ceiling and walls. You may have seen the super-black coating that makes shapes disappear but that is an expensive specialist spray done in a lab, however I have found what claims to be the nearest commercially available paint: it's just called Black 2.0 from Culture Hustle link It's opacity is pretty impressive and I have just given some smooth white card a couple of coats so when I get around to it I will see whether it does what it says.
