Large aperture may not be possible for TS' lens setup. But either way, I would think something like f5.6 or f8 would be needed to get the whole shrimp in focus. Shutter speed don't need to bother if you're using flash - just set it to 1/250 or 1/125, let your flash do the work. Do note the flash sync speed though.
TS, a macro lens will definitely help you go right up to the glass as it focuses closer. This will also help reduce/eliminate reflections from the glass.
agreed that a macro lens would do the job, but I think 35mm macro will be a bit short, those shrimp are quite tiny you know
Try getting the Sigma 150mm Macro. great lens.
Set up a small 4 x 6 ins (plastic or glass) tank with 1 pc of nice seaweed and place a blue or white background paper behind the tank, in a bright area. Then get camera ready with macro lens and polarizing filter. When ready, fish the prawn out and put into the small tank and shoot.
Hmm... are the shrimps adverse to UV light? If they aren't (meaning they don't hide from it, unlike fluorescent light), you can get one of those for aquarium UV lights which could make your job of ambushing them easier (since you can see where they are and setup accordingly before turning on the lights).
Flash? What happen if you are doing this in an aquarium?
I think the photos are fine, except that the prawns/shrimp/whatever it is called is a little too small to be seen, especially since they are supposedly the main subject. The only thing I can think of is to get a larger zoom, so that you can zoom in more.
I used to shoot my fighting fishes for fun but never serious enough. I would think if you can
- turn on the aquarium light and turn off the light in the room so that the shrimps cannot see outside.
- stand slightly away from the aquarium at 45 degrees so as not to catch your own reflection
- use a longer zoom lens with short MFD or a long macro lens.
- with the aquarium lights on, you don't need flash
- may need to switch off the infra red as that beam of light may startle the living creature
- the rest is a lot of patience. You may need to do something to make the living creature display its full glory. Like my fighting fish, I will put another male to make them flare.
See some postings here, the exposure details and the equipment used are stated:
Here are more from the same photographer:
Stir fried them, serve them on a plate. You may then take all the time to compose the shot you want. Hehe....
I have expensive camera and big lenses but don't know how to use..... Sound familar???
I will practise the photography on sakura shrimps first. They are not shy, and come out in the day. The shutter speed needed is much faster, better for my shakey hands. After i get the technique right, I think i can then venture to take photos of the nocturnal and shy sulawesi shrimps with the low shutter speed. (on tripod of course). Strangely, the colours doesn't seem right for some of the shrimps in those photos that this photographer took.
Sigh.. now all i need are those Sigma 150(300)mm macro lenses, and 3 flashguns, Olympus FL50R, Olympus FL50 and Nikon SB28
