Ya its grainy
Coz i couldnt move too close to the butterfly (it will fly away once you're too near), & my digicam (Canon S50) has only 3x optical zoom, so i had to use my digital zoom also. As a result the pic is kinda grainy.
Would definitely appreciate if anyone has any suggestions on how to overcome that limitation..
digital zoom? no wonder... try not to use it at all...if you wanna get bigger image size, it's better to crop in photoshop than use the digital zoom which is effectively the same concept. you might also consider getting some sort of closeup filters for the digicam if you are interested in macro photography.
