Question about photo types

[Frozen in Time]

Doug, I'm new to these forums also and I think this topic has been discussed extensively before. However, you raise some issues that I have also had questions about - even resorting to direct discussions with Henry Yee for some additional clarification.

To the extent that I understand it, the classification system is generally a very good framework for this relatively new branch of the hobby - namely vintage photography. But as is the case with all systems it is not perfect and breaks down in certain areas when viewed with more scrutiny.

The question that you pose is such an example. The differentiation between Type I and Type II photographs can be extremely subjective, especially if a date stamp or dated paper caption is not present (in such cases emulsion, paper type, the present or absence of brighteners, etc are additional factors that are considered). In addition, the time window of approximately 2 years has also been the subject of a great deal of discussion even during the establishment of the grading criteria.

Considering that your photos have already been graded and designated Type I, I would simple enjoy the vintage, first generation images and not be too concerned about the details that were used for their particular grading parameters.
