Sorry on this forum, we gave up on being patience. You either got it, or you don't. No excuses. I see that you were on here since March!! It's 4 months, so what if you just the camera last week? Haven't you been reading on Photography?
LOL I kid :lmao:
If she's staying still, and depend on how shaky your hands are, if you don't have VR or IS, don't shoot less than 1/100s shutter speed. It would help to know your lens and camera too. Also are you shooting it in raw and then edit or are you shooting jpeg or both? #3, watch out for background cause the light reflecting in the water makes that part blown out if you have at the right exposure. If you're shooting in the shaded area, try to not go below 1/100s of course, if you can go higher, go higher. Adjust ISO up a bit if you need to, and depend on your lens, let's say it's f/5.6. Then check the light meter to see if you have the right exposure, the line should be in the middle and take some shots. In shaded area, you do need fill lights but if you're just started, you might not have those equipment so gotta do your best.
If you haven't fully understand the exposure triangle, pick up Understanding exposure. I got it the minute I got my camera because everybody suggested it and it helped me a lot in the beginning. Play around with ISO, Shutter Speed, and Aperture. Let us know your camera, lens, and what format are you using, jpeg or raw.
