      Hi,

       

      Thanks for this forum it's very helpful

      I just have one question and i know it was mentioned before somewhere in the forum but not as mine

       

      I want to design a wallpaper with a picture of a forest and animals

      the forest picture size is 7264 x 5440 Pixels @ 300 DPI, and this is the largest picture i found till now.

       

      My question is

       

      I want to design a huge wallpaper for a room the dimensions of the wall are:

      width : 6 Meters and Height : 3.8 Meters

       

      if i enlarge the forest picture to (6 x 3.8 meters ) how to avoid losing quality? i can't find any other high resolution pictures...

       

      what resolution (DPI) should i design the wallpaper ?

      cause when i make a new project ( 6 x 3.8) using 300 dpi in photoshop first photoshop says it's too large

      and the file size become 8 GB! and if using 150 dpi the file become 2 GB still too large.

       

      the room is small and the viewing distance will be small and i don't want the wallpaper to be pixeled

      do you advice slicing the whole design into 3 or 4 parts and design every part by it self.

       

      or do you advice designing the wallpaper using the half of the real size ( 3 x 1.9 Meters ) then the printing company can

      enlarge the design into the original size, thought i don't know if the design will lose quality.

       

      any suggestions ?

      I hope you got what i mean

       

      Thanks

          I use "Genuine Fractals" to enlarge photographs for use in a grand format print.  "GF" is a Photoshop Plug-In.  There are other software apps that can enlarge your file, such as Alien Skin's "BlowUp".  First and foremost, get in touch with the print vendor you plan on working with.  They will give you the parameters on their workflow and file requirements.  The resolution of the file only needs to be around 144 p.p.i., but this depends on the actual output device.  When I do a grand format print file, I scale it @ 25% final size.  The print vendor would then enlarge it 400% in the RIP.  Most grand format print devices use stochastic screening, so even a file at 72p.p.i. will not show "pixelation".  So, for a file scaled at 25%; you'd use an image resolution of 300p.p.i., which when enlarged 400% = 75p.p.i.  So, in your case the image file would equal .95m H x 1.5m W @ 300p.p.i.  Try to send the vendor a PDF rather than a JPG to avoid any compression artifacts.
