DTVmcdonald: In your previous post about Blonder Tongue modulators you talk about "SAM" type modulators having better Q polarity transitions. I've never heard of a BT "SAM" model are you perhaps confusing "SAM" for SAW models?
First paragraph: yes, adjust colors to match, but also adjust gamma and contrast. This is very easy in Photoshop or the program that comes with my Canon cameras.

Second: yes, its SAW

I thought the problem, which is already being illustrated, is that the TV pictures do not look blue to the eye but sometimes come out blue with the camera.
You adjust the pictures in an editor so the image on the computer monitor
exactly matches what you see on the TV. You then post bog the
fixed camera image AND the file you played through the DVD player.
The reader compares those. Doing this comparison cancels
the unknown variable of the reader's computer monitor.

Look at my CT100 thread.

All this fiddling with jpgs to get a visual match is nice if needed, but it's not needed because the pictures posted clearly illustrate the stated problem - some screen shots of the roundie come out blue and others do not.

Again, the only logical conclusion is it's a problem with the camera white balance changing. The way to fix it is to find a fixed white balance setting on the camera and use it. (Probably "Daylight" will work best, but any particular setting other than "Automatic" will at least stabilize the result.)

Tomcomm, I'm asking again - does your camera have white balance settings you can choose?

Wayne...I took these screen shots using my Olympus SP-550UZ with WB set for fluorescent lighting used in homes. Later on I started using WB adjusted on a HD white printer paper illuminated outside. I never used auto WB. I ran the original screen shots thru Photo Bucket shown here. The difference in white on the two Santas is minimal but the sweater trim is definite black and blue, eh? I intend to retake the two Santas again, this time matching the sweater's white level more accurately. I will be surprised if the two sweaters don't show the same black trim color on the 21CT55 seen by human eyes.......Tom

If you examine the various photos with a photo viewing program like Irfanview or Photoshop, you can read the RGB values. Compared to the direct file capture, your photos of the roundie are very blue, and the photos of the Sony are reddish. So, if these were taken with the same white balance setting, and they appeared the same to the eye, it is a problem with the camera seeing the different phosphors differently.

There are two ways to fix this:
1) set a different custom white balance on a full white screen on each set or
2) (easier) fix the white balance in a photo program

Edit: by the way, the back light shining on the left side of the full white beard is bluer than the front light shining on his sweater and face.

New photo posting service

My present PhotoBucket charges $400 per year for hosting forums.
I'm trying to find a freeby. We'll see if Picturetrail works??
Top is 21ct55, bottom is Sony KU 27S27 of 1992. Try to call it up.

The images are visible, but if by "call it up" you mean click through to view the original, it's not working.

When Photo bucket went spamy I switched to Filckr. It's free and I can choose what size pic to display here.

Imgbb is a free site. They have more options, and you can click on the thumbnail and get the full image size. I'm sorry if my response was short. The Photobucket issues have pissed a lot of us off. I lost about 500 some odd radio photos.

Imgbb Reveled?

I understand. I Google'd imgbb and got a bunch of Apple stuff that didn't make sense to me. I'm still running XP and I still get confused. So if you could be so kind as to send me a lead to some simple internet site, I would be so grateful.
