Lures diving in the water, studio shot with two lights on a blackbackground


Lure diving in the water, studio shot with two lights on a black background by Nicola Zingarelli
Yesterday a friend showed me an image of a lure swimming in the water on a black background. This was some sort of relief because when I did my first test, I had to quit the idea of using a black background because reflections flare and light spills were everywhere. So yesterday, with renewed energies I set up my studio and the first thing I did, in addiction of putting my black vinyl background, was to cover 2 sides of the tank with black cardboard.
I also got rid of the large lights, any umbrella or softbox would send too much light out of control so I decided to go hard and small. One SB800 was set with its dome and the other with a Honlphoto Grid one of each of the narrow side of the tank, power settings changed a lot during the session so is hard to tell which has been the most commonly used. I also switched the main light from one speedlight to the other, again hard to tell some sort of rules.
Once everything was set the first test shots were suggesting a decently dark background that could be easily manipulated in Lightroom, giving me the proper black I needed. Now I needed to find a way to focus on the lures, so I put one in the middle of the tank, same distance from the two longest walls, and hoped for the best. I obviously took the focus with the lure under the water, I have read somewhere that the liquid element not only increase the magnification of the objects but also swift the focus point.
Since I was on my own I needed something that could help me moving the lures, for this reason I tied them to a thin fishing line of the length of the longest side, with a weight on the other end. I could pull the lure to one end of the tank, the weight would lift up to the opposite edge and once I released the lure the weight would pull it to the other side … gravity!
I shot with the camera parallel to the wall of the tank, with a bit of angle from above, a pretty high angle, and a very low one and achieved different results. Parallel or with a small angle worked fine, the images are sharp when the focus is on the money, but from a very high or very low angle, like in this image, sharpness and focus became an issue and I believe that is because of the thickness of the glass, that would create refraction and a bit of distortion. I’m not an expert on this matter but I believe I’m not far from the scientific explanation.
I made so many shots that my D7000 was smoking, well at least it was very hot and sometimes needed a break to process the files. The SB800 showed how good they are for the hard work, not a single complain, never stopped, always recycling fast and with just one set of batteries. Some intensive processing in Lightroom followed, I needed the blacks to be black, and the lures to be sharp and well exposed. It has sure been a challenging experience, I have made an unlimited number of mistakes and probably none of the images is really good, but it has been my first step, hopefully I’ll do it better next time.

as fotos ficaram todas espectaculares.

sei que é um desafio fotografar com vidro, água e em fundo preto, mas os resultados são muito bons (depois de tudo afinado)

1 abraço
