How big can I blow up?

with 8mp, I made prints for clients as large as 70x100cm, so i dun think there is any issue, in fact when you use a DSLR with a decent lens, you can just print as large as you want to be, the 'real' difference is details, with more MP your details are better preserved/resolve.
i even make big banner @ 3m x 9m long for my school with 8mpx camera and result is still acceptable....
I think you don't even have to worry about details when made into a banner... cos' a banner is meant to be looked from far... 8MP is more than enough
Glad to hear that! Thanks!
How do I do that?
Does it make any difference if I were to save in 16bit tiff?

It makes a difference as CS interpolate the pixel to "create" the missing infomation, creating a seudo 16Mp photo. It is better then "enlarging" the pixel to fill up the space.
I've printed as large as 16" x 24" from my pics (30D). Then again, I left the printing job to a professional lab.
I understand that with a 8MP camera, I'll get decent 8R prints at 300dpi.
Will I still get decent result if I were to blow the picture up to 12"X18" printing at only 200dpi?
Yes.
On the assumption of decent quality lens, no motion blur, handshake etc.
And go for RAW if you have not taken the image in question yet.
no not really. not unless if you're the type to look at a banner from 30cm away for a few minutes to see if it helps or not. You MIGHT spot VERY VERY small differences there.
We have moved into the new century already, and bicubic and tricubic interpolation/extrapolation has long been in use for changing size. IIRC there's no option in PS for you to merely enlarge pixels anymore.
Thus, there's no real difference between using photoshop, or using the raw converter. They all use the same process.
but it sure makes most less techy people feel more at ease.
Thanks for the tip. i found this online to share - http://www.americaswonderlands.com/digital_photo_interpolation.htm

Assuming, 1 pixel = 1 dot
(12" x 200dpi) x (18" x 200dpi) = 2400 x 3600 = 8.64MP
If this is true, then should be able to get decent results.
Unless you want to look at the picture close up, usually 120~150dpi should still give moderately acceptable pictures. Just remember, the bigger you print, the further you have to view the picture from in order to take the whole picture into your eye's field of view. And the further you are from the picture, the smaller each pixel as printed on the photo will look.
