Brightness Adjustments
I've noticed with digital cameras, the 20D included, that the camera's LED
view is well-balanced, bright. But when loaded on the PC the images almost uniformly need brightness correction. I've adjusted the gamma using the Adobe Gamma Tool so I don't think its my monitor. Adjusting is, of course, easy. But is it your experience also that some adjustments are always needed before printing? If so, do you run a batch program to tweak several phots at once? Thanks for comments. -- Remove -NOSPAM- to contact me. |

Seems every goddamn image tends to be darker than it should be. I don't have this problem with the A85 or the G2. Dunno if it's the unit or the design. I need to get a gray card to find out though. -- Todd H. http://www.toddh.net/ |

But when loaded on the PC the images almost uniformly need brightness correction. I've adjusted the gamma using the Adobe Gamma Tool so I don't think its my monitor. The LCD is great for checking composition, blowouts, or other gross exposure errors, but you absolutely cannot trust it for checking brightness levels. Its gamma and color range just aren't comparable to a real monitor. You'll find the same with a Rebel or a D70. The histogram is much more useful. I used to always underexpose stuff on my D70 by looking too much at the LCD picture, but after a little while I learned its behavior and can now nail it consistently and just check the histogram for verification in tough situations. At least better too dark than too light. |

Glad I'm not alone with this. The grey scale was a good test [I passed] so
I may just start tweaking the exposures. Thanks for the comments. -- Remove -NOSPAM- to contact me. |

Is it possible that your monitor is dark, or you are using the wrong color profile. For example I use AdobeRGB on both my computer and camera. I have the 20D and never have seen this issue. Also check the following: - Are you doing exposure compensation (using the large dial) by accident? - If you are doing the above, you may just have your LCD brightness up and it is hiding the exposure compensation issue. Musty. |
