Hi Celtic,
My other 'sifu' say aperture no more than 16 otherwise defract or something maybe wait for him to comment.
hi guys,
i would much appreciate your comments for me to improve my aqua-photo taking techniques. i realize some of the picture are out of focus and under or over exposed.
most of the pictures were taken at shutter 1/200, apeture f/18-22 and ISO 100 or 200.
thanks!

Something about the water & the fishes that calms me down.
at 1/200s it is not handshake. I suspect you are shooting at angle to the glass (glass distortion) and also your fish is not parallel to the camera. remember your DOF is very shallow only, even at ƒ/22 parts of the fish will be OOF.
as in all portraits, when you cannot get the whole subject in focus, as a rule you must have the eyes in focus otherwise the whole pix will look very blur.
where you place your flash?

actually some site said that 20d start to suffer diffraction at ƒ/11, but end of the day it is the photographer who has to tradeoff between sharpness and DOF.Originally Posted by michael lai

Not really a concern. I shoot at f/16 and f/22 at times.
Eric
is there a trade off between DOF and magnification?
There is a limit to the shutter speed of 1/200 unless we set to high speed right? But it would also mean that the flash will not fully discharge... Am I right?

in manual you'll have to adjust the flash on your own.. in Av or Tv.. got ETTL to help.. not in manual..
AH! Now it makes sense to me... Was always wondering how come my flash no longer does auto adjustment when I shoot fishes... But will auto zoom when I do shooting outside...
Thanks for the clarification! So I will need to do my own EV correction of the flash based on the exposure which I get. Correct?
yup.. however when you go into high sync.. the flash automatically gets weaker.. so take note of taht.
choy,
thanks for the tips! you are quite right about the abgle of the glass thingy.
i realize i did some shots from the side (angle to glass) to get the composition.
obviously at the expense of clarity... *sigh*
i placed the flash on top for most of the shots with the wide angle plastic deployed.
but when the fish was hanging aroung the back, i place it at angled down just below the waterline.
ranma,
dang! no wonder some of my shots were underexposed...
i was shooting in manual mode, so no ETTL! duh.
i suppose i should shoot in Av mode.
but what about the shutter speed?

you camera will sync to the x-sync speed which is either 1/200 or 1/250, more than enough to freeze any movement. Av mode is good because you choose the appropriate aperture for the required DOF and let ETTL handle the amount of flash to deploy.

wow, hwchoy that was a fast reply.
in essense the basics is to only shoot perpendicular to the glass and with the fish parallel to the lens to maximize the DOF...
now i'm thinking you must be a very patient man to get your fish shots unca choy!!

patience..haha... 3 hrs in front of tank is no joke. i'm only at 2hrs max and my hand tired liao.. somemore now choy using 0 with 100mm macro.. siong man.
whew! aren't I glad I was a combat engineer

if i had two hands on the camera it would be more bearable.
but having one hand used for the flash...

thats why you use tripod for flash mah.. or build yourself a soft box so you can slot flash and jsut wait.
