CHEMISTRY of PHOTOGRAPHY

@CSU Stanislaus

CHEM 2502 Chemistry of Photography Laboratory

General Information

The laboratory part of this course consists of a series of experiments which you can work on at your own pace. You must work in pairs. Each student must make his/her own prints and produce his/her own laboratory notebook. The last experiment is a more involved project. Each member of the group will earn the same grade for the project.

Safety

Chemicals can be very dangerous if not treated with respect. Wash off any spilled chemicals immediately from your bench, skin or clothing. Use tongs when working with prints in the developer or in any other chemicals. Familiarize yourself with the location of the safety equipment in the laboratory.

A more detailed set of safety rules for the laboratory are available. Bring a copy of these rules to the first lab session.

Laboratory Notebook

All chemists keep a complete record of their laboratory work in a bound notebook. With such a notebook the chemist has a permanent record of the procedures, results and conclusions for every experiment he or she does. You will also keep a laboratory notebook. A notebook will be supplied on the first day of the course.

Your notebook must be bound (not loose-leaf), with the pages numbered consecutively. If the pages aren't numbered, you can number them yourself. The first page should contain any identification information (a title page). The second page is reserved for the Table of Contents; this is filled in as you begin each experiment. For each experiment, you must record: i) the date the work was performed; ii) the title of the experiment; iii) a brief statement of the purpose of the experiment; iv) the procedure used (you can tape a photocopy of the procedure into the notebook); v) any data, observations or contact prints you make; vi) any conclusions that you draw from your observations and, vii) the answers to the questions in the experimental write-up.

During the early part of the course, we will collect the notebooks and make suggestions that will help you to improve it.

Finally, at the end of the course, you will turn in your notebook, this time to determine your laboratory grade.

The experiments for the Chemistry of Photography laboratory have been divided into five groups or sections. Each section may have several experiments. Each experiment must be recorded with its own Purpose, Procedure, Results and Conclusion.

There are questions scattered throughout the experiments. Be certain that you leave space to answer these when the topic has been discussed in lecture.

The grade for the course will be based on two exams and the laboratory notebook. The laboratory must be completed to receive credit for the course. You will receive a letter grade for the course but there is a CR/NC option. You can choose this option when you register or by notifying the instructor (in writing) any time before the second exam.
