Thank you Nandakumar,
Thanks Binnur, appreciated. The rose was laid flat on a sheet of glass suspended above a white card and then the card was lit from two opposing sides with LED lights to blow the background, a white reflector on high left to push some light back down into the top of the flower, camera on tripod above looking down, meter on the rose and with very little work a 'clear' background ( almost
) is created, a slight tweak in LR and PS and its not too bad.
Izzie, I also started buying plants in pots for my lady - but we are now out of space for them on windowsills!
