Help me how to photograph the fish are swimming pool

You're the newbie stage new shooting, is testing captured fish are swimming in the Lake but not capture images still blurry. E to Av mode (Canon 550d) f 5.6 iso 200-400. The doctor is no way please help me fix to images not be blurry. How do I adjust f. 18 and shooting speed is 1/100s. New baby stage is 1 week so uncertain end wedding photo ideas

I have 1 reference number of the Thai side network saw it taken quite beautiful. The doctor can help e taken like this? Want to be such a need to require that all the good tools. Its machine 5dm2 L lens + late do well anymore, what your doctor out 1 sheet are that size. Your doctor out of a piece of cut glass shop, used to prevent the tank vertically. Drawer front: the two lakes (fish) about 1-2 cm, so the fish are just moving in the plane _ so thick to thin DOF shots spoiled for me, flash or khg. ... as you like. The latter part is the rest is background. Godspeed. Try taking the sport mode, continuous shooting that you choose is a choice! Wish success! A flash and done:D


I want to f/18 that speed ensures fast it is flash or light specialized aquarium light or ISO is high (noise then quite annoying)
Send me 2 flash sheets from top to bottom, also 550D ^^. Both the 1/400, ISO-.200s. Anticipation is the Canon f/1.8 85 mm. Unless he took the 85 mm f/1.2 L for shooting fish: ">
No flash, high iso and big guns. Such panels to fairly wide angle so the DoF in 1.8 can accommodate fish. Want to capture that, he buried them for children 1 children 85 1.8, 1 em 1 em, tripod flash is *. * and password just blueberries Close friend: senior portraits Lack of light pumping flash on, indifferent. No L with 5 d mk2 do nothing.
