This is about the 4x5 peel apart Polaroid films.
Besides 55, so far, I've been using 52 and 54. 52
yields the nicest prints with a smooth and wide tonal range, but
unfortunately it requires coating. It's annoying to have to hand out
to your subject a sticky print. 54 doesn't require coating, but
is not as nice as 52. What's about 53 ? Is it better than 54 ?
Polaroid terms 54 "Proofing" while 53 is "General Purpose".

When I compared Type 52 and Type 53 some years ago, I found them to be
almost identical, except for Type 53 being coaterless. Despite
Polaroid rating one at ASA 400 and the other at ASA 800, I found them
to have identical speeds! The contrast also appears very similar.
<p>
I don't understand why Type 53 hasn't supplanted Type 52, except
perhaps because Polaroid hasn't promoted it very well.

Polaroid themselves list "fine art"
as suggested applications of 52 and 55, but not of 53 or 54.

One significant difference is that the coated prints have a much
greater expected life than uncoated. That is likely why Polaroid
limits its "fine art" recommendation to 52/54.

Sal, what is your source of the information that coated Polaroid has a
longer expected lifetime? I have never been able to obtain any
information from Polaroid about the expected lifetime.

Michael, I haven't seen much published info. on LE of Polaroid films
either (aside from a bit in Wilhelm's book), but it's fairly easy to
see for yourself what Sal is talking about. Just leave a few uncoated
prints lying around for a couple of months, and you can watch them
brown out & fade away....we shoot mostly Type 55, but I shoot some 54
from time to time, and it's a great film for proofing TMX, and doing
quickie shots that you plan to scan.
Sal Santamaura , Apr 03, 2001; 09:35 p.m.
I've the following three sources of information that coated Polaroid
has a longer expected lifetime.
<p>
First, direct observation, the same as what DK described.
<p>
Second, a book (Storing, Handling and Preserving Polaroid Photographs:
A Guide) published by Polaroid in 1983. This document has several
references to stability. On page 17, it says "While the coaterless
prints are particularly convenient for certain applications, they are
somewhat more susceptible than properly coated prints to damage by
chemical contaminants. Thus, special care should be taken to protect
them from exposure to excessive light and from harmful chemical and
environmental influences...For improved longevity, prints can be
carefully washed under cold running water for about 30 seconds, and
then hung to air dry." I suspect residual reagent - - which coaters
neutralize - - is the culprit here. Further, on page 41, under the
subject of restoring damaged photographs, one finds "A soiled print
made with coaterless black and white film should be washed in water
and allowed to dry...Sometimes print coating, using a regular Polaroid
print coater, will help to improve the appearance of a print that has
been slightly soiled. (Note: While coating a print of this type may
improve image stability somewhat, it will not give the same high image
stability that is associated with prints for which the coater is
intended.)"
<p>
Finally, in late 1998, wondering whether there were any changes to
materials which might make the 1983 book obsolete, I called Polaroid's
technical support people. They advised that information provided in
that book was still current, since the materials it covers were
unchanged.
<p>
So, in addition to the different curve shapes and differing D-Max
capabilities of these films, which might argue against the coaterless
versions on aesthetic grounds alone, Polaroid clearly admits that 52
and 55 are the films to use for long life expectancy.

My experience with the longevity of Polaroid 53 has been good. This
is, of course, no guarantee that the Type 53 will continue to last or
that it will last as long as Type 52. I just carefully examined the
Polaroids that I made in 1987, when I used both Type 52 and Type 53.
(I think 1987 is about when Type 53 was introduced.) All of the prints
look excellent and no one examining any of them would think that they
had deteriorated. Some of the Type 53 prints are slightly
warm-toned; I don't know whether this is original (from the
fine-grain) or incipient deterioration. The slight warm-tone looks
better for some of the subjects.
Sal Santamaura , Apr 04, 2001; 10:05 a.m.
I have never seen warm tones on a fresh 53. It's most likely evidence
of deterioration.
