There are 3 sets of specs given by Kodak for the processing of the Color Infrared 1443 films. The film cut to 35mm is also known as Ektachrome Professional EIR Film. It is the same film as the 1443. We have the luxury of being able to process in three methods. Below you will see some interesting results we have found. After the finalization of the AR5 process we will also post that information as well. This is from a single roll of test film so you particular end result may very. You may find that your preference is not what would be considered normal for the films so if this is the case we can only suggest that you utilize the film as you prefer it to be done. We will try to give you some pros and cons of the processing methods below as they refer to both the Aerial / Reconnaissance and the Professional market.
Negative Modified C-41: We have set up on of what we feel is the most ideal processes for this film. It is a modified C-41 process. This has a lower contrast then processing AR-5 and thus gives you more detail in both ends of the curve. To see a printable image of the graph please click on the image and download the file. IR Neg Plot:
E-6 (we are using AP-44 currently for this process)
We have NEVER suggested anyone to process this film VIA E-6. We have seen various results from images taken by photographers and have always noticed the color was not correct (realizing it is false color film). We ran some images VIA the E-6 (AP44) process of our own and noticed the same results. After plotting the curve there was no wonder why the colors have not been correct. The processor was in control when these tests were run. It was verified in control with both Kodak and Agfa control strips. Infrared E-6 Plot:
AR5 Information to follow..........
I thought I would place a couple of our tests frames on this site. You will see the below images in "infrared" with different processing methods as well as some comparisons for you to review.
This image is a shot taken of a small tree (all young new growth showing pinker) along with trees in the background that are older (thus the darker red color). There is an algae growth of sorts on the wood fence thus you see a bit of coloration in the fence. Notice too the shingles on the home that are very blue. This is a lack of chlorophyll (in other words it is dead).
These images are a comparison of a natural color image with one taken with color infrared film processed to a negative with APL, Inc.'s special set up for this method.
Till I have a little more time to take some real photos I will close with this snap shot just to give you an idea what a greenhouse looks like in Infrared.
