hey Ann ...I will look for some black backgrounds ...it may take awhile ....am sure none are plants
in PS .. its easier to remove the background completely, then picking black, white or a color from the "color picker" - then use the "paint bucket" to fill in over the removed background ...there is also a "burn" function, that works just like
an enlarger in a darkroom - without having an enlarger, or the chemicals needed to do the process
