visible photosynthesis

[I_A_N]

Yesterday I got a Raynox DCR-250 and wanted to try it out

I had a go at photographing a couple of plants in my Aquarium showing the photosynthesis of the leaves.
I waited till it was dark outside so I would not get too much refletion in the glass.

What do you guys think about maybe the contrast and the DOF
I am going to try and get also closer to the air bibbles, maybe will my Zoom and the Raynox.

I would suggest that it could do with being a bit sharper; this may be a side effect of stopping down to f/22 (diffraction). DoF is a concern at macro ranges but I think you could probably open up the aperture a bit - try f/11 or f/8 and see if those are usable. That will also let you use a faster shutter speed. At 1s, you may be getting movement from the plant and water which contribute to the softness.

Contrast is okay but I think it would be worth experimenting with different angles to see if you can get your main subject (strand with air bubble) sitting against a darker bit of the background. More sharpness on the strand would also help separating it from the light green strand in the mid-ground area.
