The program can be run online or downloaded to a home computer. And slightly more demanding users can even change the value of each tone on the negative. Easy Digital Negatives overviewĪs the name of the Easy Digital Negatives program suggests, using the program is extremely easy, but the program still makes exact corrections for transparent digital negatives. But the final photo will be of much better quality (13) than in printing a negative without correction (3). These corrections on the negative sometimes change so much that they feel wrong (12). Once we have made the correction (11), we add it to the photo. These so-called Look Up Tables can be standalone or included in ICC profiles. Most often, values are stored in a curve file, in a gradient map file, or in the latest version of EDN application also in a LUT file. The calculated corrections can be saved in different file types. Normalization and linearization can be performed manually, but we will leave this task to the Easy Digital Negatives program. Now our photo will be displayed correctly. We have to linearize the color shades or straighten the correction curve with an even distribution of tones according to the table (10). Our task is to expand these 17 tones (9), we call this to normalize the photo to correct it so that it is “normal” for our eyes. In the previous cyanotype printing case, we noticed that only about 17 color shades from our step wedge table are present for making a photographic negative or making a photo in our fictional case (7).Ībove and below these tones, all other shades are useless, as they only show completely white or dark tones on a positive image (3). We need to increase this limited range of tones and distribute the colors evenly for a perfect photo. When we plot the read color values in the graph, we observe the same values (8). The range of these is most often from entirely black to completely white (5).Īfter inverting, mirroring (6), and printing the step wedge file, we observe that only about 17 shades on the negative (7) are useful in the cyanotype technique. This file is a photograph in which there is a considerable number of fields with evenly distributed color or grayscale tones. When we want to find out what happens when using transparent negatives, we can help ourselves with the so-called step wedge file. A photograph made with the cyanotype technique (3) becomes quite contrasting, and in a photograph made with the salt print technique (4), we lose light tones, and so on. If we make a photographic negative without corrections (1) or just invert and mirror the photo (2), print and develop it on transparent material, we notice that the final photo is quite different from our original image. Only with these corrections can we produce optimal negatives or quality photography.
#STANDARD NORMAL TABLE WITH NEGATIVES DRIVERS#
The Easy Digital Negatives program (abbreviated EDN) is intended for printing photographic negatives on transparent foils and other transparent material.ĭue to the lack of drivers for printing on transparent materials or significant differences between different photographic techniques, we have to make negative corrections for each old photographic technique.
