I took this after sunset. I didn't like the evening shadows I was getting. The white background is a piece of white paper held behind the flower.
While I don't have snow for a background, I do have some blooms to play with. This just opened up within the last few days.
Jim I don't think you need to jack with it any more, looks good just like it is unless you were going for a dramatic lighting look on the plant with the white background blown white like it is. To do that tho you need separate lighting, one for the background and 1 for the foliage. Paul
