I'm going to have to ask one of my customers to print it for me on one of their plotters... give 'em a break on some work in exchange, but I think that'll be worth it.Now I just have to come up with a frame design worthy of it!

content: Quote from: Dave on November 14, 2013, 08:29:24 pmThe value of Planck's Constant has been refined a bit, as well.The Radio frequency allocations for various uses have changed somewhat.Frequencies are now measured in Hertz; the chart lists them in cycles per second or waves per second.Of course the interesting thing about this chart is to see what has and hasn't changed. By and large, the science hasn't changed, but much of the technology illustrated has.

content: Imagine how they had to make a poster like that before computers.Artists had to draw all the individual pieces of artwork in pen and ink, then they had to paste up all the pictures neatly onto a big board, keeping everything neatly square and aligned, then they had to photograph it (or scan it) using a giant camera with different color filters so they could print it using a photolithographic process.

content: Hello All,Since I'm going to have the print shop that's located close to my home print out a copy of the Electromagnetic Spectrum poster, I spent some time in Photoshop fixing some of the subtle damage the image has before getting the poster made.I left the original dimensions and resolution (300dpi) of the file as they were, but I fixed many of the scratches and crease marks on the image, plus I reconstructed the letters that had small sections missing from them. I made no attempt to sharpen the image or change its colors/saturation in any way. The antique poster looks great the way it is.Here's the URL of my large cleaned-up version of the poster image, just in case anyone else has a use for it (file size 12MB).http://farm6.staticflickr.com/5538/10866268813_c2ea411516_o.jpgRegards,Frank

content: Really nice.Also, edited by Arthur Holly Compton, Nobel prize winner in physics who discovered the Compton effect: inelastic x-ray scattering, a important advance in the understanding of the photon theory of electromagnetism. Definitely going to print up a poster.

content: Quote from: Mr Smiley on December 04, 2013, 10:17:48 pmI don't really understand. It's a printed poster. The individual print isn't the actual work, it's the image that was printed onto it. Isn't that rather like displaying a picture of the Mona Lisa on your computer display, then claiming the LCD itself to now be a work of art? He's just dusting it off.

content: Is it not a scan of an original poster; that has hung on somebody’s wall and acquired creases and imperfections during it's life, that gives it it's characterWith all those moments of time and age washed away like tears in the rain using Photoshop

content: The character IMHO comes from the way it preserves the styles and methods of the time to the present day. It's like a little time machine.Besides, it's not like they're gone, they're just gone in his copy. You're still free to use whichever copy you prefer, as is he...

content: Hello Mr Smiley,I didn't mean to upset your (or anyone elses) aesthetic sensibilities with the hours I spent in Photoshop working on this poster for my own enjoyment. I too like the wonderful vintage poster in its original aged condition. I stated that fact in my original post above. I just thought that someone else might want to see what an undamaged version of the poster looked like. The artwork is very nice indeed to look at.Obviously I didn't delete the original poster so that nobody had access to it. It's still available for download using the link in Dave's original post at the beginning of this thread. Remember, even the ceiling of the Sistine Chapel wasn't off-limits when it came to restoration efforts (at least I left the original patina intact on this beautiful poster.)My original post was just a small, well intentioned contribution to this thread.Sincerely,Frank
