Is it possible to contact print an inverted image on an lcd monitor to a piece of photo paper?

Q. I am wondering if you could invert an image in photoshop, make it say 5x7, black out your screen tape a piece of photo paper on there,turn the monitor on for a second or whatever and produce a developable print.

A. Yes. There is no reason whatsoever that this shouldn't work and produce a low resolution somewhat out of focus print given the correct exposure time and an environment that prevents the paper from being significantly fogged during the process.

A few things to keep in mind. There is a piece of plastic between the actual displayed pixel on the monitor and the piece of paper you are applying. This will mean that the light will diffuse and scatter somewhat before it reaches the paper thus reducing the clarity of the print. Also your pixel count per square inch on your monitor will be low in comparison to what is considered acceptable in a high quality print. This will depend on your monitor but even the very best monitors do not come near the 240 dpi that is required for a high quality print. Lastly the monitor will not have the orange mask that light sensitive photographic paper needs to produce a proper color image. This could likely be emulated though by experimenting with different degrees of orange being added to the inverted image.

Regardless...cool idea and worth giving it a try. With the right image it might distress it in such a way it might be desirable in some respects.


Does LCD monitor or plasma give more better quality image?
Q. I know LCD monitor is cheaper then plasma but more LCD have 1080p, right? Which is better? Why there is a price difference? I know LCD is liquad, and?

A. Plasma has better response time so will show movement better than an LSD TV; important when watching action particularly sports. A good LCD has a 5 Milli Second response time where as a good plasma 0.2 MS.

LCD screens are generally much brighter and better suited for rooms the receive a lot of light. Plasma's are better in darker rooms; easier on the eyes.

Generally plasmas are 42 inches or larger. LCDs are manufacured by more companies.

LCDs sometimes are manufactured with pixles that are burned out causing a dot on the screen. Plasmas have problems from screen burn.

I decided after much research to forget about buying a set for another year; I was holding out for 42 - 48 inch 1080 p plasma. A couple of weeks ago Tiger Direct had a 42 inch LCD 720 p set on sale for $699 and I couldn't resist. I am extremely happy because I am getting a great picture, I have all the bells and whistles (PIP, split screen, TV tuner, multi connectors including computer) and I paid a lot less than anything I have seen before or after.

My advice: Get a good inexpensive 720 p that you you like (plasma or LCD) make sure it has an antenna (broadcast hi def is better than hi def on cable or satelitte), and enjoy. 1080 p is more expensive and really only gives a better picture with a Blue Ray DVD (also relatively expensive).

By the time prices fall for Blue Ray machines and discs and more channels are broadcasting in hi def the price of TVs will fall dramatically. Move the set you buy now into another room and get yourself a bigger set
