If I were to try to take students past the basic would certainly ask me to explain the difference between the Unsharp Mask and RL deoonvolution Method but (1) Although I understand the math of ‘convolution’ and 'deconvolution" my class would not understand the math. I spent some time playing with it but the relation to what I did with the sliders and the visual effects of my image is hard to follow. RawPedia Book attempts an explanation but a demo showing the effects of the sliders would have been useful. ).ħ50×526 36.9 KB the explanations that I could find for how to use the threshold slider on the attached screen shot for the ‘sharpening’ options isn’t clear. (Bonus points if you release your teaching plan liberally for us to re-use - future educators will thank you. It is true that a process-based approach with learning materials is lacking in Free Software, but that’s what this site is hoping to start rectifying. On the plus side, there’s a community of folks here who are happy to help! Maybe you could outline an approach or lesson plan where we can identify what types of topics need to be addressed, and we can enumerate the possible methods for approaching them effectively (along with more details on the technical aspects of the tool as well, if needed). (I’m assuming you’ve seen the Getting Started section of Rawpedia). The problem is that not all of the tools may be needed, while others may be indispensable. There are many different tools, and they each have their use. If you wanted to describe the type of approach you’d be interested in teaching, there’s a few of us who’d be happy to help elaborate on the tool (or at least make sure to find an answer for you). Adobe support products aren’t perfect but I have always be able to find answers that I need. Each time I start thinking each would answer my needs, but each time I run into an obstacle where the explanation is not adequate. Just to be clear I have read the RT supplied documentation, I have viewed numerous on line tutorial videos, and I have searched for RT books. I am saddened by this but I can’t ask my class to use software that I can’t explain. I edit using Gimp, Lightroom, Photoshop and I have used earlier versions of RT but in spite of a number of hours spent experimenting with RT tools most of them remain a mystery. I don’t consider myself a novice with photo editing. Unfortunately I have not been able to find any support documents that provide a cogent explanation for many of the numerous controls/options that RT provides. For some things, like correcting white balance, RT is great. As a teacher I have thought that I could ask my class to use RawTherapee 5 in place of the costly Adobe products that work well but are pricey.
