Strange question from client: can you blow up a photo from a Polaroid camera?

I told the client I was pretty sure the answer was no, seeing that there isn't a negative of digital file.  But what the heck, I'll ask here in case I'm completely wrong about this. 

So, is there a way to blow up a photo taken from a Polaroid camera?  

Funny you should post this......I had someone give me two Polaroids the other day and ask the same thing.

I've scanned prints many times with surprisingly good results but I've never tried it with a Polaroid. 

I think the old adage applies here......garbage in, garbage out.

If the Polaroid is decent (as a Polaroid can be) to start with then I'm sure you could enlarge it to some degree.

Yup, it can be enlarged but will you be happy with the lack of quality?

It would be possible, but it would depend on the original. I've scanned in mine and could print out a copy in whatever size, although I don't know that I could go too large.

If it's an older Polaroid it could be decent quality originally, but I don't know how well it would have held up over time. Probably would depend on how it had been stored.

The current 'integral' film by The Impossible Project, now rebranded under the Polaroid name, is different than the original Polaroid technology. I find the images to be softer especially using a plastic camera/lens; I get better quality with my SX-70 with glass lens and the ability to focus. The scans to me don't capture the quality of the originals, which I think is due to the thickness of the photos (which are a packet of the film, negative, emulsion and chemistry that squeezes thru rollers when ejected).

If it's an image shot using an older Polaroid Land camera on peel apart film (that Fuji made) those are different quality. When you peel them apart you get a positive photo and a negative, but the negative is too dark to see much. Supposedly it's possible using some combination of bleach and I don't know what to remove the black backing to get a usable negative. Haven't tried it. I can't remember offhand if I've printed out any of my scans or what size, I'd have to go look. But those being on paper with a separate neg they don't have the thickness of the 'integral' Polaroids and are different quality.

Find out what the original is like and what type it is, and it could if nothing else be scanned and reprinted digitally as maybe a 5x7 or 8x10 - but the quality likely won't be sharp enough to enlarge a lot and get a good quality copy.

You might be able to pull it off if going on canvas, but only to a certain point.  Just not much you can do with such a small image size. 

Only two options, scan the image or 1:1 reproduction with a macro lens.
