Yes, we like to have 3D photos in our computers, but sometimes we want to show some of them to our friends in their house or to someone in a pub. But how to put the 3D photos on a paper? Are there any problems or is it troublefree?

   To get paper 3D photos you can choose a few ways. To print them with an ink or laser printer (it has to be able to print color pictures - anaglyph uses the color separation to produce stereographic effect - and it's color parts has to be printed on the 3D picture).
   But the best way is to use the same method as with classical digital photography - using a photo studio. Many studios are able to create photos from digital data - and you only have to find the right one for your country. (Just try a search engine with good words to search - for example "digital photo development" in Google). Good studios offer the possibility to upload your images via internet and after processing they send it to your address.
  
A few rules
   If you want to have nice 3D paper photos, you should abide the same rules as with the 2D digital photos. The resolution of your photos should be no less than 300 dpi (dots per inch, for 10 x 15 cm (4 x 5 inches) the resolution of your photo should be 1176 x 1764 dots). Lesser resolution = worse quality, but don't worry - slightly lower resolution won't be visible for most people.
   If you need to change colors of your photo, do it before you create the anaglyph (change colors on the left and right pictures). Not later.
   You can let to develope not only 3D photos but rendered 3D pictures as well. Use the right resolution and don't forget the colors on your screen can differ from these on the paper (you can calibrate your monitor, but for the beginning don't bother with it).
   Our paper photos are OK - are going to try it as well? If your answer is yes and you are going to take the paper photos with you to show them to your friend, don't forget your 3D glasses at home...
