Thank you for your assistance. I was able to pull the rose our of the background by using several technics.
I first matted the rose bud. I did the Pleasantville effect and then I was able to Chroma Key out the black and white. Luckily I did not lose anything on the rose.
I had to repeat the process for the green of the stem.
It took me about two hours and looks quite good.
Blessings,
Kimberly
