5/5/1950 Photo

I don't know if I've posted this before or not, it's from an 8x10 Negative I found tucked in among my Sams folders, pretty sure I bought this on eBay some time back and forgot about it.

I don't have a scanner capable of scanning a negative this large so for now I propped it up against the monitor displaying a white screen and took a picture of it.

I want to get it professionally scanned and see if there's enough detail to make a repro of that Dynamic Demonstrator.

There is another copy of this on the ETF Site, http://www.earlytelevision.org/lasalle.html

The close ups look pretty clear.

I've seen similar setups for service training but never for sales; that was a very serious dealer!

Nice. Wait. 8x10 negative? Wouldn't that fit on any ordinary flatbed scanner?

Yes, but most consumer scanners only have a very narrow back lit area designed for slides and film negatives.

I could scan a 2" strip at a time and use software to stitch it together but that's probably not optimal.

I have shared the same dream for many years. I don't think any of these exist anymore. A nice detailed closeup of that demonstrator would be nice.
Probably some professional shops out there that can scan it in very high resolution without any compression.

Anybody with an Epson V700 could make a good scan of that.

I have a V-550, it had the largest backlight I could find at a reasonable price point.

Oh... well now I'm pretty sure this'll work: Just scan the negative on the flatbed like any piece of paper > photoshop > invert colors > ??? > profit!

It doesn't work, I've tried before, it comes out all muddy, it needs the light passing through.

I got it. Get an lcd monitor, display on it a completely white image, put that on top of the negative on the flatbed scanner.

Sorry, I've seen this done on ebay listings, and it's a disaster because the separate RGB pixels mess it up.

Oh yeah. Damn.

Crack open the lcd monitor, remove the lcd panel. Pure white backlight with diffuser.

Hi Members-i have been experimenting with lcd monitors showing a white image as a backlight for imaging negatives-to get around the individual RGB pixels visible in the image,i placed an opaque sheet of white plastic to diffuse the light in front of the monitor and it works great!
hope this helps.
