Rotifera XVI: Rotifer Workshop, Zagreb, Croatia, 2022 |
|
|
| |
This is the overview of the workshop to be held on Sunday, 04.09.2022: "How to Get Nice Rotifer Images". All the materials which are presented here will also be availabe at the workskshop on USBl.
All images here on the plingfactory are all edited with Photoshop, so based on the experiences with this app, the workflow at the workshop will also be based on it.
However, as I have recently discovered, many of these steps and image processing can also be done with GIMP, so working with GIMP will also be a topic at the workshop.
Since GIMP is available free of charge as an open-source project, it is advisable to download a GIMP-version for the corresponding OS and to have it ready on the computer which you will use for the workshop.

The topics presented here are only a range of what could be done in the workshop. This will of course depend on the needs of the participants and the apps available and how the different apps can be combined. The material needed for the exercises presented here is provided for download in the individual sections. This is an introduction to the image processing in the workflow that I use for my images. Image processing is done by apps like Photoshop. In this workshop we will also use the open source app GIMP. |
