I was thinking about opposites when I came up with this idea, merging a winter and a summer image into a message of sorts.
It took me awhile to go through my 30,000plus pictures and find suitable candidates, finally chosing a black and white winter image that was taking during a snow storm and a color flower picture.
I decided to make the winter scene the dominant theme. The flower image needed scaling down and positioned properly to maintain a natural size ratio. Next was to remove the blue sky background and merge the layers. Afterwards a bit of tweaking contrast, detail and saturation...done.
