We're debating now on which one of the self-portrait family shots we took on
Thanksgiving day to get enlarged. If we go with one of the ones taken with
the Yolympusmat 124G tlr (6x6 neg), how big can we enlarge? I've never had
enlargements done from anything other than 35mm.
By my measurements, the negs measure 57mm, as against 36mm on the longest
side of 35 format. However, a typical enlargement from 35mm is usually done
in 4 to 5 ratio (8x10, 11x14, etc). So only a maximum of 30mm of the actual
neg is being used. Assuming you can use 56mm of the MF negative, you could
make a 4 to 5 ratio enlargement from a 6x6 negative at 20x25 inches that
should equal the quality of a 35m enlarged to 11x14. Or an enlargement 28x35
inches would equal one made from 35mm at 16x20. I've had made 16x20 inches
from a 35mm in the past, and it was okay for me.
So, it seems all things being equal, that is the same film, same lab, etc,
that a 6x6 negative should give a cropped enlargement 24x30 inches, and the
quality of the enlargement should fall somewhere between the quality of a
11x14 and a 16x20 made from a 35mm negative. But I realize things are
sometimes different in real life than what they calculate out to be on
paper. I'm hoping someone here has had some experience, and can maybe give
advice on getting something enlarged to 24x30 inches.
[Okay, I realize that this is assuming also that the quality of a Yash*c*mat
lens is equal to a Zuiko - not likely to happen on this list :-) ]

These things are so subjective, aren't they? A true zuikoholic would
make one of each and compare and then notify the list that the zuiko
image was superior.
I think, truly, that the zuiko lens is going to be substantially
superior to the Yashicamat. On big enlargements people say they can
see a substantial difference between a Yashicamat image and a Rollei
image. While capable it was a cut below. It was a low priced
substitute for an expensive camera and now it is a very old design,
certainly not even multicoated. So all things are not equal.
Additionally there is no reason to crop the ends off the 35mm frame
because it is usually done. Only if it makes a more pleasing
composition.
The method you choose makes a difference too. With traditional
printing methods with an internegative the larger frame may fare
better. A high quality drum scan should get all the quality possible
out of either one. I have recently seen a couple of amazingly sharp
and colorful 32 x 40 inch prints from 35mm slides at the Rowells'
Mountain Light Gallery. They were scanned and digitally printed and
superior to any chemical process I have ever seen.
