Hi

I've been approached by someone who wants to enlarge my Kodachrome slide from 1970's to poster size so he can frame and display it .

He has passed on advice about going to a shop who can scan it as high as 24MB and then put it on CD so I can send it away to him.

Does anyone have any experience of this? If so, I'd be glad to hear of your experiences and how much it might cost. I live in Woking, England.

Cheers

Ray

Do you have a film scanner? If so, which one?

Even the inexpensive Minolta Scan Dual II (or III) can produce 24MB TIF files. But no matter what, to go to poster size you (or whoever makes the print) will have to interpolate the image.

Ray,
This isn't a direct answer really, but something to think about.These days the "average" consumer film scanner can give you a file at least 24 MB in size. Most can go well above this.

If there is a full service camera shop near you, I would think you can have them do it, or they can send it out for a drum scan or Kodak Pro-CD scan which will give you about 90MB per image.

In that there seems to be some knowledge of the technical aspects of this on the customer's part, I'm surprised he didn't specify the desired DPI. Also likely you may hear, "I can't open the file" or "my printers say their machine can't read the file." Having a camera shop print (reproduce in some way) the poster and mailing it to the customer would avoid this.

Of course Kodachrome 25 would be preferred for a poster, but if K64 is what you have, so be it. Keep in mind that if you supply the image on CD, you are leaving the possibility of unauthorized image reproduction in the hands of the customer.

Good luck!
