Merry Christmas
 

Enough Ferris Bueller and DVE for a while. Something more seasonal for the 21CT55 to display.

Great screenshots. The cat jumps right out at you...

Wondering why Santa's sweater looks neutral white in the first shot and bluish in the 4th shot. An effect of your camera, or visible to the eye in person also?

nice

to my eyes the flesh tones are amazing

Santa Sweater Mystery
 

I re displayed the two Santa s on the 21CT55 and the 27in Sony. The sweaters were identical white with black patterns. there was no bluishtint on either. So there must be some anomaly in the camera ?? I've included the Santa redo and the original video capture jpg that drove the two TVs .

Is your camera set for auto white balance? Fixed setting for "shade" might work better.

I'm old enough to remember seeing Color TV in the late 1950's in my town. However, there was so little programming, and especially during daytime hours when the department stores were open, that it was hard to see a color show on a color set. No local color from our 2 local stations, but the NBC affiliate could pass thru network color. I do remember one Christmas season seeing a 21" roundie in a store window at night showing a Perry Como Christmas show. It was very nice as we drove by. I also remember one time staying at a motel in Tulsa, there was a big roundie color TV in the lobby, and I sat and waited for "some" color..but alas all I was able to see was the station call sign with the number in color. I was a child very eager to experience color TV, but found it very very hard to see any. My families first color TV was the Motorola 23" rectangular model..the first rectangular model from a US manufacturer, AFAIK. Its kind of ironic that I'm seeing vastly more color images from 1950's TV's than I could ever dream of seeing in the 1950's.

As far as comparing different brands and models, well just forget it. If a store had a color set, they had ONE on display. No multiple models to choose from. But I am from a fairly small town. Probably under 60,000 people in the 1950's.

Santa Sweater Mystery
 

Suspecting a camera problem, I re-did the display of the Santas on both 21CT55 and 27in Sony.
Judy and I agreed both TVs produced identical coloration of the two Santa's sweaters. I screen-shot both TVs and downloaded the camera.
I was astonished to observe the "fuller Santa" was black/white on both TVs while the "lesser Santa" was black/white on the Sony but blue/white and his hair was bluish on the 21CT55! Why this should be is not understood by me.

Skinny Santa has some blue highlights in his hair, too. He looks a little punk rock! I think it may be your camera's white balance, though.

Heathkit GR-2000
 

Yes, it was the GR-2000, the 25 inch set. I still have it in the early American style large cabinet, built it in 1976.

More 21CT55 Screen Shots
 

Still no resolution of the “Santa Blue Sweater” issue. Since this thread is a documentation of 21CT55 video monitor screen shot picture quality, I am including my Flicker photo site’s new Photo Stream format I recently discovered. Again, the stitched photos show the 21CT55 shots on top with the Sony comb filtered shots below. Flicker Photo Screen presentation size is much bigger then the early grouping previously presented. Relative picture detail of the RCA vs Sony is readily discernible.

Several of the stitched shots (but not all) are bluer on the top.
Do I understand correctly that all these appeared to match to the eye?

Is your camera white balance set to a fixed setting (daylight), or is it set to automatic? You cannot get consistent results on automatic white balance, as the camera is trying to guess the lighting conditions, and slight variations in the content can cause it to move one way or another.

Testing New Screen Shot Process
 

Wow, looks like a terrible level of block/line artifacts on my screen. Maybe this is from converting the original to a smaller resolution?

Wayne....Does the guy look better in this screen shot? The Photo Bucket seems to over-drive on high detail photos. The new guy has less intense detail.

The cat is in a silver steel drum but displays in deep blue. So I'm going to work on the cat screen shot and find out the problem. Surely this anomaly would have been obvious to the human eye viewing the 21CT55 crt......Tom

It's better, but not completely clean. Not a good endorsement for Photobucket!

You need to do what I did:

Get some nice JPEG files from wherever.

Get a DVD or Bluray player that will play them. Get a GOOD Blonder-Tongue
modulator, either an agile one or a BAVM-SAM one. A plain BAVM will do,
but the SAM does better at +Q to -Q transitions.

Play one to your test set.

Take a picture with your camera, very preferably to RAW.

Use your raw processor, whether from the manufacturer or
Photoshop or whatever. I use Photoshop. Put the computer monitor on the
to of the TV. Have the jpeg playing. Simply match the
developed picture on the monitor to the image on the screen.
Save the image as jpeg.

Voila! Upload the original and TV image to here. The reader
can compare them on his monitor, and will see the EXACT same
difference you did.

DTVmcdonald, you would have Tomcomm match two pictures and then expect them to show a difference? I don't understand.

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.

I think what he means is that he adjusts the primary levels in the file that contains the TV screen shot so that it looks the same color wise on his computer monitor as the TV screen image appears to the eye in person.

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

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.

http://pic20.picturetrail.com:80/VOL.../322344539.jpg

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.

Still checking out PhotoTrail.

Use imgbb and be done...

What is "Use mgbb and be done"? Is it free?

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.

https://imgbb.com

Just click on that link, hit upload, upload your images, and it'll spit out a list of links to post here.

Checked out Picturetrail
 

Not a PB user, so don't know for sure...
But you actually completely lost the pics -- as in you cannot look at them/retrieve them privately? I thought the $400 ransom was to be able to link to them in 3rd-party sites like VK, not to just look at them/download them yourself. That would be bad, bad, bad.

Chip

Yes, they'd still be there unless he closed the account. And there are fixes to allow them to be seen in forums, getting around the PB limitation. So if they were left alone, and any of us added the PB embed fixes, we could see them in the forum the same way they were originally.

So for any of you that don't want to pay the Photobucket 3rd party hosting ransom, at least don't get upset and close your PB account. That only screws everyone else from viewing the images in the threads.

Fixes: http://antiqueradios.com/forums/view...p?f=2&t=324150

.

Don't bet on that working for long. Anyone with a PB account should be able to download their photo's to a safe place, but at some point that option will likely go away. Long ago I came to the conclusion that there's really nothing permanent about the internet. It's all subject to going poof.

Thanks for sharing that fix!

Another PictureTrail upload try.
 

Seems I've forgotten how to upload photos.
