Thanks everyone.
I particularly like how the Blue Voodoo shot turned out.
The last pic of the acan was a bit of a challenge and I'm not entirely happy with it but as is the case with all images that give me trouble or issues, it's been a good learning experience for me. I've very happy with the form of the image, it is the excessive green that is a problem for me.
That acan is incredibly green and like grape jelly purple. It sits under the shelf of a plating Monti cap so it's a bit shaded. My first attempts at post processing yielded this unholy glowing green thing and all I could figure is that I overexposed the green in the original image capture. I've had lots of times where I've overexposed white / light color growing tips on acros, but never so much of a non white color so pervasively in the image. Makes me wonder if one can overexpose black?
In hindsight what I should do is man up, shoot in full manual and stop hobbling around like Tiny Tim on my Av crutch. I need to push myself out of my comfort zone.
What I did instead was to discard my first attempts and reimport the RAW file reducing the exposure considerably. That toned down the green to essentially realistic levels, but in doing so it also darkened the oral disks of the polyps to the point where the delicious detail was being darkened. So this image is a compromise between realistically green and visible polyp faces.
I love the purple lipstick on each of the polyp mouths!
