Why my “action” shots are blurry even shooting on AF-C, is this a lens or camera limitation? Actually, lens stabilization does very little for sports shooting. It stabilizes the camera/lens combination. But for sports, its the subject that is moving. |

Canon DSLR Lens Correction Any modern desktop or laptop computer has hundreds (if not thousands) of times more processing power than any camera. That is why post-processing rocks. |

How does the gray level in a target impact the true color after calibration a couple hundred K of color shift is exactly the type of correction that I bought the ColorChecker to correct. With subtle colors, that is a huge difference in how it looks. I want a photo that shows the colors that I see on the wall at the time I take the photo. An accurate recording of what is there. |

How does the gray level in a target impact the true color after calibration OK, here are the photos. All shots were taken at the same place with the same lighting, in maybe 3 minutes elapsed from first to last. flickr.com/photos/the_old_curmudgeon/sets/72157632879493705 |

How to handle existing gear if you start your own business from financial site? You really need an accountant to help you set this up. Pay one who knows the laws and tax code in your state/location. Website registration is $12 a year. Don't worry about it. |

What exactly is a “circular motion” when using a lens cleaning pen? I can see three possibles: 1) run the pen around the lens, like grooves on a record, keeping the pen at a single orientation. In this, the pen will effectively twist 360 degrees as you complete circle. 2) run the pen like a record, but twist the pen as you go, so that it stays in the same position relative to the groove. This is like the needle/cartridge in a record player. 2) as #2, but rotate the pen the opposite direction, so it does a 720 degree rotation as you go around the lens. The problem I see with #2 is that if you have grit on the pen, it will stay in the same place each lap. |

What lens should I purchase for newborn photography with the Canon T4i? Image quality and that range and your budget are incompatible. You can get one good IQ lens and another cheap one to cover your range, but this is an overly constrained problem. I use my 17-55 F2.8 on my grandkid, but that is a $1200 lens itself. |

What Nikon camera should be used in the high mountains Batteries hate the cold. Technically they lose the ability to supply sufficient current at the needed voltage as they get cold, but for practical purposes they lose 90% or more of their capacity. Plan on many batteries, and consider carefully how you will change them when on the mountain with snow and blowing winds. |

What Nikon camera should be used in the high mountains I think this is an overly constrained problem. $1500 is simply not enough of a budget to get a body that is weather protected and two good lenses suitable for macro and landscape work. Further restricting it to Nikon only further pushes this out of a realistic question. |
