Digital Lith Tutorial - Process Modules

image

With version 4 of digital lith there came another step of modularization which brought process modules. This means that digital lith is no longer stuck to one process. You now can select from different processes and with the use of the digital lith sdk you are even able to implement your own process module. How you can do this will be part of the next episode where in this episode we deal with the import and use of existing process modules available on the digital lith exchange.

When you use the program without having any process module installed, the top of the parameter section will look like the one on the left. There is simply no mention of process modules at all and it looks very much like in previous versions.

To add process modules without implementing them yourself, you will have to visit the digital lith exchange. As with presets and streaking modules you do this via the Exchange menu. Once you select the Process item you will be presented with a list of process modules available on the exchange.

At the time of this writing, there are only two extra process modules available. One is the implementation of the demo process module as demonstrated in the sdk documentation. The other is a very simple process from the beginning of my digital lith journey. It is my first attempt to implement a digital lith process.

The usage of this dialog is similar to the streaking dialog. You can click on Read more … to get a bit of description of the process and you can select as many processes as you like and click on the Import button to get them loaded. Keep in mind: As with streaking modules, process modules are loaded at program start up and to get the process modules working you will have to restart the program.

Now you imported at least one of the modules the parameter sections head will look a little bit different. As you can see, now there is a selection button for the process module. The selected process is still the standard lith process which comes pre-installed with digital lith.

If you click on the button you will be presented with the list of installed process modules. Here you can see that all available process modules have been installed. Now let us select a different process module. And since we are going to visit the Demo Process in the next episode anyway, let us use the Old Process 1. Although it might imply that there will be an Old Process 2 – I can not guarantee that since I lost some of the older sources due to some hard disk issues and that early the sources were not under source control (enough tech speak for now).

Now that you have selected the Old Process 1 process module the parameters section will look different, the standard process parameters are gone and replaced with the parameters of the old process. And with that the parameter section looks … clear compared to the standard process.

The development time part is the same for all process modules. Or to be clear, it is not part of the module at all. And then there are only two parameters, the grain and the dilution. Yes, that process is from when I still thought it would not need to much parameters to have it implemented to my liking. But then ...

Anyway. You can now use the program as before, running test developments, running in batch, setting the coloring, using streaking modules, creating presets and so on. All that is different is that the driving force of the program is now a different process module.

If you define a preset with this module then when selecting the preset later, this will also select the correct process module. If in the meantime the process module has been deleted, then the standard process with default parameters is used instead. Also the history will take care of the process module. That means if you go back an forward in history the correct process module is used.

Now let us have a look at the result produced with the above settings for the Old Process 1 when applied to the demo image:

You can do your own testing of it and see where you get with it.

The only process modules available besides the standard process are more or less for demo purposes. But there is more to come and in the end, why not build your own. There will be an Alternative Standard Process coming . But that needs some time. But once it is ready, you can easily install it without having to upgrade the program itself.

That finishes up the second last episode of this tutorial. The next episode will be about the Digital Lith SDK: Click!
