About the Image(s)

This is a nudibranch in the sea slug family. The nudi part of the word is because They have no shell. Their defense is that they are poisonous to eat. They do not have eyes so the focus should be on the sensory organs in front. The upright part in back is the gills. They live on the bottomed will sometimes call up on an object or a wall. There are rare in the Atlantic but fairly common in the south Pacific. They are a favorite critter to photograph in the Philippines and Indonesia. They are usually 1-3 centimeters in size. I like to shoot them because of the variety. There are thousands of different ones.

I used a Canon 5d Mark 1/V with a 100mm macro lens and two flashes (1/200 sec, f/25, ISO 640). I use photoshop Camera Raw to enhance photos to my liking.

Hello Michael: Welcome to Close-up Group #63.
Very colorful sea life positioned well on a slight diagonal in the frame.
Exposure seems spot on, I would consider darkening down the background somewhat, it is a bit bright as is and your very interesting subject would stand out better.

You have good sharpness on the subject that is possible shooting with a 100mm macro lens at f/25 at this high magnification.   Posted: 10/06/2026 05:37:23

Hi Michael. Very interesting subject and it is tack sharp. I agree with Murphy on darkening the background to help nudibranch to stand out even more. Looking forward seeing more of your work.   Posted: 10/08/2026 11:40:12

This is a wonderful image shot under challenging conditions. The colors of the subject are nicely presented, and the subject is as sharp as it needs to be. The subject is effectively separated from the surrounds. There are many sharp areas in the background which I find distracting, but slightly blurring the background will remove this effect. I also agree with the earlier comments that the background is a bit bright. Darkening the background would help here. Finally, I respectively disagree that the subject is tack-sharp, and I might suggest sharpening the main subject and adding some more contrast to really make it come to life.

I have included a version of this image where these suggestions have been applied to illustrate my thoughts. Let me know what you think …
