Sorry, the wife was home and it was taco night, yeeha,,,
OK, this all happens in the layer pallette,
Background,,,Hit the keys alt J for a copy,,
background copy,,,go filter/blur/gaussian blur,,,adjust 16 for now,,make sure layer selected
press mask button, the little square at bottom with round circle,,,see the white square appear..next to background copy layer?
select paint tool, paint with black in center of flower, black will hide according to opacity setting on that layer, make sure the white square has an outline around it, that means it is selected.
paint out close to edge with soft brush.
Now add new layer in layer pallette, new layers are transparent.
I selected the pink when I had the brush tool on by pressing the alt key and clicking on color in picture, go to the top and change the blend mode, it says normal, change to color.
with low opacity, like 3 to 15, start to paint where you should think it will look good,,
you can always start over. You should pick this up, you seem pretty sharp to me. One other thing, double click on the layer name and you can name it blur, color,,what ever you want to help you remember when you start Dreaming. Now keep the right layer selected so you only change that one layer. Or select the layer you want to work on in the layers palette by clicking on it.
Hope this helps I was a hungry boy and my sweety said the right things. the tacos were greatttt. Any other crazy help, just ask me in here.
