Calibrating monitor (CRT) to match third vendor printer Wait, you're saying the print shop's recommended colour management practice for customers is to have them go out and buy a second hand CRT monitor and then calibrate it by eye? The first thing I would suggest is looking around for a different printers. |

Why does a bigger sensor have better dynamic range? @JohnCavan that's true for dynamic range in good light. At ISO100 the APS-C Pentax K5 beats the full frame Canon by over two stops, however at ISO800 and above the full frame Canon is ahead, and in really low light the gap is over a stop, which is about what you'd expect from the sensor area advantage. |

Why does a bigger sensor have better dynamic range? Good explanation of the theory but completely ignores the practice! |

Do you still need an ultra wide angle if you can now stitch images? Stitching is perfectly mathematically correct provided you pivot the camera about the centre of projection and correct for barrel/pincussion distortion, which is often minimal for medium to long focal lengths (the type you would use for stitching). Any downgrading of data through post-processing will be more than made up for by the stitching result having a huge increase in resolution compared to single shots with a wide lens. It's not uncommon to end up with over a hundred megapixels in the stitched result. |

How to simulate different focal length and sensor size on an image? @LaurenceNyein it's a simple linear relationship between focal length and field of view, to simulate a 400mm focal length with a 200mm image, just half the width and height. |

Signal:noise ratio not really decreasing with ISO for Pentax @JohnCavan Anything done to the RAW file that's irreversible is bad IMO, if I want processed files I'll shoot JPEG! |
