The new version of EDN Basic can be used to produce negatives with any printing device, which means we can also use all printer brands and models. In conjunction with ColorBlocker, EDN achieves maximum results even on the cheapest printers. It can be used to produce negatives in almost all photographic techniques, including those with a minimal tonal range.
The results are displayed instantly. They are stored in curve files for GIMP and Adobe Photoshop. Higher quality Gradient Map files are also stored in GIMP and Adobe Photoshop files. However, LUTs cube-type files can be used in most programs, such as Adobe Lightroom, Affinity Photo, and of course, Adobe Photoshop.
To this version of Easy Digital Negatives Basic, I also added graphical representation of the results. The graph basically shows a so-called linearized correction. This is a linearized representation of a linearized sample. But let’s leave the details. Basically, this is some kind of needed result. If the result is a nearly straight curve, we have made a correction for a near-perfect negative.
By clicking on the graph, we can also display the so-called raw or scanned data before corrections. In this view, we can discover several causes for various errors. Most often, we will see a saw graph, which indicates that we have applied the emulsion very poorly on paper. In this case, all the tones on the left side of the sample are darker than on the right side. Etc.
What’s new in this version?
- The program now works on all operating systems.
- The accuracy of the corrections is increased.
- You can open or drag and drop any number of samples to the Choose files button. In this case the program automatically calculates the average correction.
- The new version of the program now also calculates the curve and Gradient Map corrections for the GIMP program.
- Corrections are also added to the LUT file. In recent years, this type of data has become increasingly popular for photo and video corrections (see also Advantages of EDN).
- LUT-type corrections can be used in all slightly more sophisticated photo editing program.
- A graph with a linear representation of corrections is added to the EDN program.
- By clicking on this graph, we can also show the raw data of the sample, that is, the real color values before correction (see image above).
- To simplify the EDN program, the correction section has now been added to the standalone Fine Tuning EDN program.
Making a sample
- At www.EasyDigitalNegatives.com, we find in the Downloads menu, the EDN_RGB_101_TEMPLATE.tif, EDN_RGB_101.tif, EDN_RGB_256_TEMPLATE.tif, and EDN_RGB_256.tif files. Of course, I recommend using grayscale wedges with 256 fields.
- In any photo editor, we open a sample file, in our case, EDN_RGB_256.tif.
- The sample image is horizontally mirrored and then inverted.
- File is printed on transparencies or paper with of the selected blocking color and choosen print density (see my book Easy Digital Negatives for more information).
- Using a transparent film, we create a positive image with the chosen photographic process.
- We scan the sample image (learn more in the video Scanning The EDN ColorBlocker V.3.0 Sample).
- We crop a sample photo using the template to the required size. Because cropping these samples is the same as cropping HSB images, you can also view the following videos: Cropping EDN Samples In Photoshop, Cropping EDN Samples In Affinity Photo, and Cropping EDN Samples In GIMP.
- We drag the cropped photo to the EDN Basic program Choose Files button, which instantly calculates the results. We can run the application online, but we can also run it from our computer. In this case, we need to unzip the EDN_Basic.zip file on our personal computer. We find this file in the Downloads menu. We can then double-click the index.html file.
- With a click on the appropriate link in the Download file type section, we save the desired results in any folder.
- To check the quality of the corrections, we apply corrections to the file EDN_RGB_256.tif. To print the final image, we use the results on our final image. We add the correction file to the positive image!!! We can also see how to add appropriate corrections using different programs in the examples for colored negatives (Adding EDN Gradient Map To Adobe Photoshop, Adding EDN LUTs To Adobe Photoshop, Adding EDN Gradient Map To GIMP, Adding EDN LUT To Affinity Photo, and Adding EDN LUT To Adobe Lightroom).
- When corrections are added, we invert and mirror the image.
- Optionally, in this stage, the color of the negative can be added usinf the ColorBlocker, after which the negative can be printed.
