The reason the water in these shots are blurry is because photosoto was trying to capture a sense of movement in the water by using a slower shutter speed. He could have used a faster shutter speed and frozen the water so that it did look in focus, but you lose that sense of movement. Some photographers try to go for a silky look to the water by using even slower shutter speeds.#2 is nice but the waterfall is OOF.
#4 is blurry and it looks too dark to me.
You used flash for the first one, assumingly. Not a great choise; try with a tripod instead.
It's probably a white balance issue. When you shot with the flash turned on the camera used the flash white balance setting. But since the flash couldn't illuminate the whole scene, the areas that the flash couldn't reach wouldn't need the flash white balance correction and ended up looking the way it does.Yeah, I had no idea what it would do, so I was just trying different modes. The color turned out pretty though. Why would the flash turn the sky to purple/blue hues?
You mount the camera on a tripod and then let the camera use a slower shutter speed to let enough light in to expose the shoot. Since the camera is on the tripod you don't have to worry about camera shake making the picture blurry.what do you mean with the tripod?
