HI THERE. IM JUST A LITTLE CONFUSED ON HOW TO SEND MY FILES. I WANT A POSTER PRINTED THAT IS 196cm height // 143cm width. WHICH IS THE SIZE OF THE DOCUMENT I MADE ON PHOTOSHOP. HOWEVER IM CONFUSED ON SAVING THIS FILE AS ITS TOO LARGE APPARANTLY AND CANNOT BE SENT BY EMAIL. IVE FLATTENED THE IMAGE AND SAVED AS A JPEG BUT ITS STILL A HUGE FILE. COULD YOU TELL ME WHERE IM GOING WRONG?? IM SO CONFUSED.

    You really need to concentrate on the image size.  Look at Image/Image Size.  Best to use image size in pixels of height and width.  Uncheck resample image and change one variable and see what happens.  THen check resample image and see what happens.  The resolution is also a variable.

     

    So bottom line you only need to send a hi res image and state how large you want it printed.  Do a web search for print size vs image size to see what resolution needs to be.

    Most likely you increased the pixel count too high which inflated the file size required. An image that large is not viewed up close so you do not need to print it at a high resilution like 300Dpi.  Pring an image that size at 100Dpi will be fine.

     

    196cm x 143cm at 300dpi is 23150px by 16890px = 391,003,500px  391Mpixels

    196cm x 143cm at 200dpi is 15433px by 11260px = 173,775,580px  174Mpixels

    196cm x 143cm at 100dpi is   7717px by  5630px =   43,446,710px    43Mpixels

     

    Your camera pixels are most likely nearer to 43Mpixels then to 391Mpixel  intepolation can do just so much adding that many pixels will only produce a soft image anyway IMO
