How did I pass this picture? Another fantastic portrait. You capture the soul of the man. Is a portrait as deep as if we were seeing her eyes.
Regards, Carlos

This is the picture I prefer: light, atmosphere and attitude of the fish work well.
You ask if the change from Velvia 50 to 100 helps to improve sharpness. The answer seems to conflict with the characteristics of the two films, but in fact this change can help. For example:
Velvia 50 has more resolution than Velvia 100, so he has the ability to capture more details, which favors sharpness (so it is widely used in macro). However its low sensitivity required to open the diaphragm and lower the shooting speed , two factors that contribute to undermining the sharpness.
Velvia 100, despite having the largest grain, still has an excellent resolution (probably did not notice the difference in an ordinary diaporama) and can close the diaphragm 1 point, which helps us solve the problem. How? In two ways:
1 - Close the diaphragm (to f: 8 or f: 11) usually improves the performance of the lens.
2 - Close the diaphragm helps minimize the aberrations caused by the passage of light from water into the air, especially through a flat surface, and this is the main problem.
Probably you did use the 35mm lens through a flat port and the diaphragm at maximum aperture. If what I am saying is correct, the most important step to resolve the problem is to use the 35mm with a curved port (dome). Also you can use the Velva 100 which follows very well and allows close the diaphragm.
Hope this helps
Best regards, Carlos

As two other photos of this folder, despite appearances this picture is
not digitally manipulated. The picture was taken in 1978 and the final
image was created in the lab, with a simple technique called sandwich,
in which two negatives are juxtaposed in enlarger. The print was made
on Agfa paper paper and subsequently scanned.
