can i blow up a pic to 70cm x 70cm

NeVeR

Hi all,

I dont normally get things printed at this size but a friend has asked to get some pic's of his children printed onto a canvas thats 70cm 70,

The pic was taken on a 8 Megapixel camera,

The canvas is 70CM x 70CM. Will the pic look crap when blow up to this size?

With Canvas you can get away with a lot more than normal prints.

I don't see why it would be a problem unless you have cropped the
photo significantly ?

An 8mp image is 3264 x 2448 (or thereabouts, that's some specific brand of camera, other brands are probably similar). 300 dpi is normally suggested for good print resolution, yielding a nice quality print of 11 inches by 8 inches (roughly A4 or so).

70 cm is just short of 30 inches, so yeah the picture is probably a bit on the anaemic side. However, its being printed on canvas, and its being printed large, so it won't be examined as closely as a 10x8 print would be. Depending on the image it might actually turn out ok. I've printed 6mp images up to A3, and some of them worked out well. There's a guy who posts here on boards who comes highly recommended for custom print jobs, the personal touch might make all the difference.

I'll be designing the pic.. he wants effects done to them, and i've done some samples, He's really happy with them, I seen photobox.ie have some nice prices,

Would a digital SLR be better to take the Pics with ...Sorry i know it would but would there be alot of difference..

Talk to the user stcstc on this forum - everyone here who's used his services highly recommends him.

Theres a plugin for PS called Genuine Fractals which allows for upto 600% magnification of imagaes with next to no detail loss.

stcstc

there are actually a few of those plugins

all of them claim to have no loss as they supposidly use better algorithms than photoshop does

BUT

i have tried both genuine fractals and Aliens skin blow up, and written an action in photoshop and to tell you the truth only on the largest prints would you notice the difference. and thats only on paper prints, not on canvas


The way i do it in photoshop is scale using bicubic smoother, but do it in steps of 10%, ie if you need to do about 200% enlargement, do it like 10 times using 10% increments.

i've done 30x20 from a 6mp image in print rather than canvas - in truth it was really very good. Up close i.e. examining it from less than 6 inches away, you could see a little distortion / pixelation but nothing that would be noticed when it hangs on a wall.
