Blowing up pictures to poster size

[BC69]

Hey Guys,

Has anyone had a picture blown up to a large poster size? Maybe 48" by 72" range? I am thinking about getting a print from http://www.rprincephoto.com/ of the new CR-6, but very expensive in large sizes, so that made me wonder if I could get a 1 off print myself blown up anywhere online?

Also, would it matter the megapixels of the camera is came from? As fas as how quality would be at such large scale.

Thanks,
Tim

It MUST BE high res if you want to blow it up in size. The larger you want to go, the higher the resolution should be. (not always, but it helps in quality.) If it is a low resolution and you blow it up in size, it will be pixilated, or become bit-mapped (fuzzy edges) and will look like crap, especially in a larger format.

This is a case of More Is Better! I'd check with the printing company for their recommendations. I got these .jpg specs from the website of my local photo place for fine art prints.

11x14 1650x2100 1.9MB
12x18 1800x2700 2.8MB*
16x20/24 2400x3600 4.9MB*
20x24/30 3000x4500 7.7MB*
*Larger files at 300ppi will produce better quality prints.

I have printed an illustration at 24x36 on a wide format hp printer. The file was 4900x3200 3.5MB and it turned out nice. The printer was mostly meant for CAD drawings so it's not "fine art" quality but good enough for hanging around my office.

Viewing distance makes a differance as well. Just like cars, it may look better at 10' than 2'.

Where are you gonna hang that bad boy?

Tim, printers prefer 300dpi, but I've done 250dpi and it turned out pretty good.

Thanks Guys - my camera is 10megapixels - not sure how clear the picture itself is, or all that detail. how exactly can I find that out? It that a dumb question.

And most people would think hang it in the garage, but I live in the middle of manhattan - its going on my wall which is why I wanted it pretty massive.

Also - my brother has taken some pictures with a Digital SLR - guessing those would be better candidates?

Tim, can you e-mail the original file/image to me?
