I generally avoid doing photos like this mainly because I tend to get weird banding effects where the colors change from red, magenta, pink purple to white, especially in out-of-focus areas. On the flower itself, it's a more gradual change. Is there anything that can be done about this? This was shot with a Nikon D7000, Nikon 105 AF-D micro, raw with no adjustments at all. If I were to increase the vibrance, saturation or contrast at all, the banding-artifacting gets even worse.

I believe i see what you are talking about.

You shot at f/16 and SS 0.6 perhaps Diffraction related?

Seems a bit long on the SS

Did you use an off camera flash?

Here is a crop of a recent red/pink/white/ azalea i recently did at f/11 SS 1/200 with off camera flash.

No. I used a diffuser on the available light, tripod, remote release, mirror lockup, etc. I needed f16 to get the three things in the middle all in focus. They are sharp, so I don't think it's diffraction. The banding occurs in out-of-focus areas. The little solid lines of purple where it's supposed to be a softer transition from color to white. It's jarring.

Just as in film, the longer you can keep the shutter open the more saturation you get. Maybe thats it..Bleed over?? other than That I got nothing else.

Hey Rob,

I also get this issue sometimes shooting with D700. What setting is your camera on? Landscape or vivid right? It seems this pushes the saturation so far that when there is a big shift from colour to white then this happens. I get it all the time.

Go into RAW converter and change camera setting to Adobe Standard, sometimes it works for me, and then you can adjust saturation once in PS without the banding.

Hope this helps

I appreciate the tip. The posted image was shot raw, imported into lightroom with adobe standard preset (acr), with no virbrance, saturation or contrast added. I think the sensor is just incapable of rendering the fine difference in the transition. It seems to happen most in pinks and reds. I'm shooting more today, and I'm going to do it with flash and faster shutter speeds to see if that helps.
