2nd pic is sharper, first pic still got shake. look at the white part of the eye, can see.

2nd picture is darker although shutterspeed is slower, probably cause of metering so just take note.

basically think of shutterspeed as your house curtain. first is closed. when you open, you let light in. how much light you want to let in, is how long you open your curtain. so 1/50 means you open your "curtain" for 1/50 of a second, and 1/200 means you open the shutter for 1/200 of a second and so on.

exposure compensation is like, when you take a black fish against a very bright background (maybe your white wall is reflecting the light from the tank light). then you need to compensate the stops by putting it to the plus section to ensure your fish is properly exposed. how much to compensate, depends on where you meter also.

hope you get what i mean, if you have any doubts do clarify yep? cheers!

phoo....this is deep indeed...

ok...let me recap bit by bit.

shutter speed is the speed at which the shutters open and close. 50 means 1/50 of a second. 200 means 1/200 of a second. So 50 means the shutters open and close slower than 200 rite? 200 should open and close faster.

And when I select the shutter speed, I need to take into consideration the lightings. A brighter background will enable me to use a faster shutter speed, like 200 and a darker background will need me to select a shutter speed of 50 so as to enable more light to get in, yes?

The first pic was taken with 0 exposure and with shutter speed of 200

The 2nd pic was taken with 0 exposure and with shutter speed of 50

I cant see any difference, except maybe the 2nd pic (shutter speed of 50) is abit clearer and sharper...could see the sec pic is rather a little under exposed. i would ahve thought is the other way round..1st pic 1/50 sec 1/200 hehe

Whats the diff in the shutter speed? And whats exposure for?

sec pic is 1/50 yet sharper ! first pic is 1/200 but got handshake . nice try bro at least u noe ur cam is capable right?

yup...without this thread, I never would have known.

Meaning to say if first pic is 1/200 and no handshake, it would have been perfect?

Heres another one of my takes. Just took a pic of this angel using shutter speed of 200.

I used super macro for this, and this is how it turned out.

believe it or not, i was infront of my tank, waiting for the rite moment for the angel to come out of hiding, without the fan on, and just the tank light on. I was like kneeling down and my wife glared at me just now.

ya bro...i just checked. I used AWB for that pic of the angel just now. Theres dayligh, cloudy, flourscent, tungsten etc...so i dunno which one to choose.

Btw, thanks.
