Why does my DSLR's viewfinder ignore the aperture ring on a legacy lens? It would be helpful to know exactly which lens you're using, as it will have a bearing on the answer. |

Can the camera select wrong exposure just because of color? @enthusiast: The histogram is just a plot of levels of brightness on the X axis and how many pixels are at that level on the Y axis. Usually this is done for the color channels plus one of the overall level. What I looked at was multiple histograms for small crops within the petal areas of each flower. The red picture's crops showed pretty consistent amounts of light all the way around where the white's showed less light on its right side than on the left. I did that as a way to quantitatively determine if one side was brighter than the other in case my eyeballs were off. |

Can the camera select wrong exposure just because of color? @enthusiast: I just took a look at the histograms for several square areas that consisted of just the flower petals. The red one is pretty evenly exposed all the way around, but there's a definite shift in brightness between the left and right sides of the white one. That difference will have an effect on what the metering system sees. |

Motorola Razr Maxx compression removal @Francesco: The Camera API has allowed applications to set the compression level since API level 5 (Eclair). API level 8 (Froyo) brought camera profiles which have high, medium and low quality levels determined by values in the file I suggest modifying. If Mak cares to burn rep on a downvote for my answer, I'll be more than happy to rebut it by pointing out the places in the Android source where all of this happens. At any rate, the proof is in the pictures. Thanks for pointing this out. |

Practical Difference Between Nikon 80-200 f/2.8 and 70-200 f/2.8? The 70-200 is an amazing lens, but the last few generations of the 80-200 were good in their own right, too. |

Why do camera manufacturers use different lens mounts? The Four Thirds systems are maintained by a consortium of seven manufacturers of which Olympus and Panasonic are two. Other than Sigma, manufacturers that currently have proprietary lens mounts are notably absent from the consortium's roster. |

How do I get the high contrast sharpness seen in this B&W portrait? ...And since there's going to be post, shoot in color and do the conversion there. The camera gives you exactly one choice about how the conversion is done, and if you don't like it, you're stuck with trying to adjust it. Shooting raw wouldn't hurt, either. |

Do professionals use auto mode? Automatic anything is just another tool in the tool box. Someone who's good at what they do (as opposed to someone who does it for a living) knows when to use which tools. |
