Using vectors to scale up images?
on May 24, 2010 at 11:22:28 am


I have created a poster design in photoshop. The poster is A4 at 300DPI and it was created using images from HD video (so 72DPI). I would like to beable to make the poster bigger, preferably A3 size. However in photoshop if I scale up the images to this size the quality will be poor.
I have been advised that I can convert the images to vectors in Illustrator and then enlarging them should not decrease quality. Is the possible and how would I go about it (I tend to stick to photoshop for design work so I don't use Illustrator that often)

Converting to Vector in IA will result in stylized images, they won't be photographic.
But you would open the raster image in IA, and with the image selected click Live Trace on the main menu. There are presets or you could go into custom settings to make adjustments that better suit your needs.

I'd look into Genuine Fractals, it's a Photoshop plugin.
