[QUOTE="Pretzel, post: 543162, member: 12257"] I can tell you the most glaring thing that I see right now... the shutter speed on quite a few of 'em at 1/13 at 55mm focal length. At 55mm, even with VR, you should be shooting at a BARE minimum of 1/25 shutter speed, but I'd recommend nothing slower than 1/50. Shutter speed should equal out to your focal length for most handheld shooting, TBH. Any lower, and you run the risk of hand shake, no matter how steady you feel, and it's that hand shake that I'm seeing in most of the pics. Either that, or the lovely youngster is moving a bit, and 1/13 just isn't gonna freeze your subject. The outside shots are the same, focal length of around 150mm, but a 1/50 shutter speed. Not only a bit of hand shake, but overexposed, as 1/50 is quite the long exposure for a beach scene, even at ISO 100 and f11. The one of the Febreze is at 150mm but 1/8 sec... ouch! Minimum shutter speed of 1/150 there, again matching the focal length is a bare minimum. Aperture mode doesn't know how you're shooting, whether it's handheld or tripod, or whether your model is moving or not. It's just taking the aperture given, the ISO available, and setting a shutter speed to allow for proper light exposure (if possible), but it doesn't mean it's always going to choose the correct shutter speed. Keep an eye on the shutter speed in your viewfinder, and if it's slower than 1/xxx (xxx being your current focal length), either open up the aperture or increase the ISO to get it higher for these types of shots. (EDIT: Or add light - flash, overhead, etc. BTW, for portraits and single subject shots that are non macro, f4 works well). On the pool shots outside, you were at ISO 800, which is way too high for an outdoor daytime shot, too. Overall, I think a solid understanding of the exposure triangle (especially shutter speeds as compared to focal length of the lens) is gonna help you greatly with focus, exposure, etc. [/QUOTE]
