You cannot get a good comparison between the film in the yellow and green boxes by shooting Kodachrome on Monday and shooting Fuji on Tuesday, or by shooting with two cameras as you travel about the countryside. You have to make side-by-side comparisons not only on the same day at the same time of the same subject, but also with the same camera body, lens and filter in order for all things to be equal. There are too many variables between weather conditions, time of day, sun angle, camera body shutter speeds, coloration of lens glass and filtration (UV-Haze or IA Skylight?) for one to make a fair and equal comparison of different films by looking at images made under entirely different situations.
Get some short-exposure rolls of the yellow and green film boxes and go out to make test slides of a stationary subject using the same camera, lens and filter for both rolls. Write down the exposure settings for later comparison with the resulting exposure on the slides. View the Kodak and Fuji slides side by side on a light table to compare color bias, shadow detail, coloration, exposure, etc. Do not use two side-by-side slide projectors for this as there might be variations in the brightness and coloration of the projector bulbs as well as in the projector lenses themselves. Now, go out and repeat this for a different weather condition (overcast versus sunny) or at a different time of day (e.g. morning versus high-noon). For an even better comparison, shoot several rolls of each film-type of the one subject and then send the identically-exposed rolls to different processing labs for this test. Then compare them as above for a true test between the films in the yellow and green boxes. It will cost you the expense of a few rolls of film and processing and a few hours of your time, but you will see the differences between films and labs and THEN you can determine which you like best. Until you have done this, you are comparing apples and oranges. There is no such thing as "color memory". John B. Corns --> SPORRS: Serious Photographers of Railroad Related Subjects
