It is not my intent to be rude but to list the many pitfalls in the process of transferring digital photos of a TV image to a post on the forum.
1. The TV should be calibrated with a colorimeter for accurate grayscale, gamma and colors (CMS).
2. The camera white balance must be set for the TV spectral output. White balance adjustment is only present on the more expensive digital cameras.
This means displaying patterns at IRE 30, 50, 80, 100 to set the camera white balance.
3. To prevent motion blur one must use a Hi Def recording like a Tivo to pause the video to capture the image. The TV luminance may not be sufficient to allow fast exposure times. The camera should be on a tripod.
4.To view the image on a PC, the PC monitor must be calibrated. Many are poor OOTB. This requires a colorimeter with bundled monitor calibration software like the I1D2. But this calibrates not just the monitor but the monitor/display adapter combination. Most adapters, AMD/Nvidia have many settings that can alter the image.
5. And the software used to view the image on the PC must not alter the colorspace. I have used IRfanview (free) for many years and have learned to trust this program in this regard.
6. The photo must be uploaded to Imageshack or flicker in high resolution for the forum member to view on his/her PC which must also be calibrated as in 4. above.
7. If the image is to be viewed on the members TV via the PC display adapter DVI/ HDMI out the question of color space contamination by the adapter is present again.
8. Better yet the member can dump the image to a flash drive connected to his TV using a player known to not alter the image.
Not to discourage members from posting photos but to take these with skepticism and realize that even photos on reputable web site TV reviews are also subject to such errors.
BTW my camera is the Panasonic Lumix TZ5 and my favorite site for digital camera reviews is dpreview.com. The TZ5 is listed as 'highly recommended'
