Cut 4x5 print paper in 4x5 film holder

[ToddB]

Ok guys.. I was thinking how this would work.. Pre-cut 4x5 fiber base paper to go into 4x5 holder. Shoot your image for 5 seconds wide open. close slide like you would exposing fim and processes it in traditional manner in dark room. Something different and experimantal.

You'll wind up with a paper negative, which can be printed by placing a fresh sheet in contact with the negative and exposing to a bright light.

For the negative use EI 4 or so, process in whatever you use for prints.

You can do it with 5x7 and 8x10, too.

You will find that 4x5 film is actually a tiny bit narrower than 4". Measure carefully before cutting, or forever fight to get the paper laying flat in the holder.

That's right. Glass plates were 4" wide, then when film took over, metal holders were made to use the film in glass plate holders. These required that the film was slightly smaller than the glass plate size.

A vestigial side effect from the days of film sheaths that had to themselves fit into the earlier glass plate holders.

Todd, if the 4x5 negative to print size relationship is the same as 5x7 you'll find that you can fit the paper into the film holder with a little difficulty w/o cutting for just experimenting. It won't lay quite flat though but it's not bad.
I'm sure there's lots of information on apug about paper negatives.

no need to panic
its just about 1/16th" you need to trim off
if you cut too much,
just use a piece of double stick tape you
won't even know you had a problem.
there's no point in sweating the small stuff

you might think to use exhausted print developer to
develop your print, you won't have over the top
contrast issues if you flash your paper too ...

have fun !

Check out the paper negative sub-forum here on APUG. Lots of good information. Also, be aware of the Harman Direct Positive Paper, a fiber-based paper with an emulsion that, after in-camera exposure, reverses to a positive image in standard paper chemistry.

Also, I believe that the Harman paper is cut to film spec, meant to be used in regular holders...but I could be wrong.

I believe Harmon paper comes in 4X5 and also 3.9X4.9 to fit the holders.
