Making larger format negs?

sarahfoto · Mar 17, 2010

Until this day I have only used (smaller) large format negs and contact printed them. Now I want to go bigger but any suggestions on film? (I do not want to use a printer of course)

Sure, enlarge to ortho film. Just google "enlarged negatives." N.b, if you try to search for that using the APUG search engine, you won't get much; use google instead.

For color, I think you would want something low contrast maybe like a Portra 160NC.....

Oh sorry, just noticed that this was a question for colour. This opens up the possibility of doing an E6 enlargement, so there'd be no need for an interpositive- the slide would itself provide a suitable negative image for ra4 printing. I haven't done it but I think I'd try that. Something like astia might do the trick. Might be too contrasty.

are you trying to make enlarged negatives( negative-->negative)?

there used to be a film that could do that, I don't believe its made anymore.

now, you'll have to make either
1. an interpositive, to make another enlarged negative
or
2. a nice scan(preferably a drum scan), and then have that digit@lly recorded back onto film. Most labs offering this service use Portra 160NC, due to the lower contrast.

Then there is always the old fashion way.
Shoot a larger camera.

Enlarging negs has two problems...the first problem is increase in contrast and the second problem is loss of sharpness. When you print a copy neg, the print is a second generation copy. John Powers has the best and direct way to make a larger neg.

Good luck.
