Most compact cameras take their best photos below ISO 200 and the SD3500 IS is no different. Photos taken with plenty of light will give you excellent color and sharp, fine details (though they look more digital than I'm used to seeing from Canon images). Canon typically does well at balancing noise reduction and noise in images, and that's the case here. Despite details getting softer, they're not smeared beyond recognition straight up to ISO 1,600. Color is consistent, too.
