Use a Scanner to Turn Your Small Phone Photos into Giant Prints

Want to made giant prints of your tiny phone photos? Instead of doing the enlargement purely with Photoshop, Photojojo suggests using a scanner for high-quality enlarging. Simply resample the small photo at 360dpi, print it out on high quality matte paper, and then re-digitize it using a scanner at 360dpi and the print size you want. It’d be interesting to see a side-by-side comparison of this technique versus simply resizing in Photoshop and printing that image directly.

    Does it fix her hat too?

    how old are you………lol….

    Why 360 dpi?

    They could have done something to explain what this does that achieves their objective rather than just use Photoshop directly to resample & upscale the image.  My guess is this adds paper texture to the final poster print.  Other than that, I have nothing.

    Sounds stupid too me… Just resample it in PS/Gimp – scanning printed pictures will make quality even poorer, out of focus, soft, will add some dust and paper texture, unless you really want this hipster effects added you shouldn’t use scanner to enlarge printed-cell-camera-picture.

    The print, scan cycle is simply a blur filter which reduces the anti-aliasing caused by higher sampling frequency introduced at scaling…

    Wait, I know… Connect your iPhone (4s) up to a projector, beam the image at a cinder-block wall, take a picture of the projection using a Diana camera. Have the film developed, and print your enlargement. That’ll work.

    Ahha. That’s how the police find out what’s written on the license plates when the find the photos too blurry

  • Photos

    Totally stupid, 2 prints for the price of 2 (and more wasted time). Why dont we make a vhs copy of a vhs and do it a few times, I am sure the quality will get better too.

    A valid alternative to the default Photoshop resize/resample is to use a fractal-based resizing algorithm or the stairway method to blow those files up. 
    Going analogue then re-digitalising it is certainly not the most efficient or effective of ways.

    He’s right you know.

  • David Tamburo

    this is a joke

  • Lop

    This should do the same thing, perhaps:

  • Kevinhong

    Can’t you just click “enhance”?

  • Deckard

    And give me a hardcopy right there

  • Amadeusz Leonardo Juskowiak

    Because 300dpi was too mainstream :)

  • Cheeseburgermadness

    You’re an idiot

  • Denisgermain

    This has to be one of the most stupid technique ever!
    360dpi is not optimal resolution for all printers… (and only speeds up printing)Most people cannot tell the difference between a 200 and a 300dpi print anyhow!Simply increase the size of your image in PS and add a couple of filters to “enhance” the image (blur, median….)and if everything looks fine… get it printed…. if not, the classic add noise, is always an option to cover-up the poor resolution.
