Everything depends upon what you are trying to accomplish.  I wanted to contact
print mine, so I shot 8X10 (these can be seen at
http://mywebpages.comcast.net/hmpi/Projects/BearSkins/BearSkins.htm) and used
the Van Dyke process to print tem out.  I primarily use 4X5 (this and larger is
considered large format - 120 film is considered medium format) for its
flexibility and have enlarged it to 16X20, though I feel that some images would
not work well with this size enlargement.

It really depends upon what you are looking to do, so you'll need to make the
judgement for your own images.  I do not believe that there is a universal
answer for this.

 The issue is the degree of enlargement. Enlarging 35mm to 4x6 increases
the
 image area 16 times. Increasing a 4x5 to 16x20 increases the area only 4
 times.


4x5 to 16x20 is also a 16X increase in area.
You are right, the issue is the degree of enlargement and I'd add, the
resolution you start with.

Murray,

I all depends on your own taste and sensibility.  I have made mural size 
prints from 35mm pinhole negatives and been very happy with them.  I 
routinely make 11x14 prints from my 35mm negs and the 6x6 negs from my Zero 
2000 pinhole camera.  When I had access to a 4x5 enlarger I made 11x14 
enlargements from negatives made with my Santa Barbara pinhole camera, and 
again, they looked great to me.

with lens images. - Original Message -

Murray,

4x5  5x7 were also LF last time a checked.

 I was very unhappy with 4x6 prints from 35mm pinhole.

Could we see some of those results?

Prospects of enlarging 4x5 and up, are excellent
Prospects of enlarging 35mm format to up to 8x10 are fair to good (at
least), but you have to shoot for the intended print size and  properties.
I wish I can show you some new results of enlarged 35mm negatives, but I
haven't done pinhole or any other type of photography in ages :-( , last
image I did was for a workshop I gave back in Nov/2001, the negative was a
35mm format size PAPER  NEGATIVE taped inside this ugly camera:
http://members.rogers.com/penate/cameras/14f.jpg (a disposable modified
camera) and then enlarged/cropped to 6x6, here is the result:
http://members.rogers.com/penate/doll6x6.jpg  (the negative is shown at a
greater magnification, than the 6x6 print itself).  I'd call that a fair
minus result, but bear in mind the original was a 35mm paper negative.  This
other example made back in 1996, is from a 35mm film negative using the same
ugly camera above and enlarging it to about 8x10:
http://members.rogers.com/penate/fire.html , I'd call that a fair plus to
good result, obviously I am not talking about artistic merits but whether
the image falls apart or not after enlarging it.  The pinhole size, btw,
was optimum for the focal length of that camera.
