Have you tried printing the bitmap and then scanning the print out in the highest resolution you scanner does? Save the file in a lossless format, ie .bmp, and then re-size that.

I understand that someone wants to blow up a postage stamp size image to A3 size. Take a photo with good quality 35mm colour film and then use the negative to print at whatever size you want. Just the way it was done before computers. If you want it in digital form, digitise the final print. Or photograph it with a digital camera with the largest number of pixels you can beg, borrow or steal. It will give you more picture info than the normal flat-bed scanner. A film negative/slide scanner might be able to give good resolution, but that requires the subject to be transparent. regards Dennis. -----Original Message--Sent by: brianb at kdfisher dot com dot au on 16/08/04 10:19:32----- Original sent to: os2genau at os2 dot org dot au, Ed, There is a tool called Corel Trace that will convert bitmaps to vector formats but I don't know how well it deals with complex images.

For best results using this method, you will need ISO 100 or lower film in large format and a macro lens in around 180mm focal length. May get away with 80mm but I dought it. I have an 80mm macro lens here and I'm pretty sure it won't get close enough to fill the frame and maintain focus. As far as 35mm film goes, ISO 100 is probably the highest rating to use. At ISO 200 and above the film grain will be quite noticable enlaging to A3 size prints. Not so much with large format film. In any case you will need lots of light and a tripod. I'd recomend going for ISO 25 film ( will need tonns of light for this one) if you want virtually no grain. But even if you went for 35mm ISO 100 or even 200, the film grain will be much less than the pixalation in digital form. In fact I have 20" x 30" prints from ISO 200 film that aren't too bad. Of coarse if the small image is digital already, then all that above is next to useless. You will get pixalation from the screen on film :-( .

Agreed. Playing scanner with a camera, digital or not, is a hell of a business. > > Of coarse if the small image is digital already, then all that above > is next to useless.

Because, even as vectorized, the file will be of an unhealthy large size. -- Groeten uit Gent, Kris ---------------------------------------------------------------------------------- **= Email 6 ==========================** Date: Mon, 16 Aug 2004 18:34:20 +1000 From: Dennis Nolan Subject: Re: Expanding graphics Gavin Miller wrote: > Hi there, > >> Take a photo with good quality 35mm colour film and then use the >> negative to print at whatever size you want. >> > Ahhh my area of expertise. > > For best results using this method, you will need ISO 100 or lower > film in large format and a macro lens in around 180mm focal length. > May get away with 80mm but I dought it.

But assuming that the object is photographible, an enquiry to the local camera club might find a member with a copy stand and largr format camera willing to take on the challange. Another avenue, assuming a decent copy stand is to use filters and photograph in black and white, then index and recombine the images for the printing or digitising. Thats how they used to do satalite imagry back in the seventies.

I've learnt a lot through all of the answers. It also seems to have been a topic that has interested a few people. It is good to see that members of this list are not afraid to think of non-computer related solutions. The idea of Macro photographing the image and then enlarging it photographically is probably the best solution, except for re-creating the Image by hand manually, already at the size required. Which Mike has very kindly offered to attempt to do for me. To let you all into what the graphic is all about. I will be attending the Warp Workshop in Germany in a few weeks time and since the event doesn't have a logo that could be used on Polo shirts, I thought I'd try to create one. Unfortunately I attempted to create it using graphics that were simply too small and when I tried to enlarge my "work of art" - it didn't look very much like a "work of art" anymore ! So once again, thanks to all who replied to this plea for help. Cheers/2 Ed. ----------------------------------------------------------------------------------
