The background adds a great contras to this .. I do like it

The two different color in the background make no difference in the quality of this photo. Beautiful orchids well shot.

I do agree with Raj, it does not matter to me either, Lyn this is lovely!

I think the background color is fine, Lyn. It coordinates very well with the earth tones of the buds while allowing the flowers to jump right out. I like the framing as well; it's subtle and well done. I particularly like how the tones of brown on both sides switch intensities--not too much, just enough to trick my eye into thinking it changed placement, from front to back. The only suggestion I would have, if you can with your camera, is to increase your f-stop just a little (I would guess the f-stop here was around 2.8 or thereabouts?). The buds in the lower left are tack sharp while the flowers are a touch soft. I'm thinking the branch bearing the buds was just a little closer to the lens. If you can't adjust the f-stop (some cameras are finicky that way), try to position the camera so that the elements in the scene that you want in focus, but are on different sides of the capture (as in your image), are as close to the same distance as possible from the lens. I do this whenever I'm pre-shutter positioning the camera, visually measuring the distances from the elements to the lens, sometimes even using a tape measure or even just a stick to do it. It takes a little time to set up but makes a world of difference in post-shutter processing.

Just a thought. I'm always impressed by your imagery.

Happy Trails
