The software comes to a state where it is all about workflow, not about certain tools that are mostly self-explaining.
So for you articles and trainings (don't know what you are doing there so I just can guess...) I think it colud be interessting to adress different kinds of workflows including appropriate sets of keyboard shortcuts and workspaces, different ways to customize the tool tabs and so on.
5.0 now really enables a fast workflow... similar to V3. I'd emphasize the "V3" in V5.0. to create awareness.
Certainly 5.0 should have been 4.2. But that's history and 5.0 finally doesn't lack of essential V3 features anymore. Not in every detail but roughly.
Some hints regarding workflow:
- you sure noticed that the focus mask applies to the image in the viewer and to the thumbnails but does not apply to the focus tool. That's a consequent concept: you can check focus with the focus mask and at the same time you can see the clear image (in the focus tool). Create a workspace / layout for that.
- tool tabs: me I switch tool tabs via keyboard - next/previous. So for me it makes a lot of sense to reduce the number of tool tabs and to place those I rarely need on the side. See screenshot - I actually only use quick-, lens-, exposure- and color-tab. With the new local copy/apply I don't need the adjustments-tab anymore so I swapped it to the side. I access metadata via ctrl+I, library via ctrl+L.
The "details" tab is included in my lens tab. "overlay" is in the camera tab and cropping is in the output tab. I never use rotation. "Process" is my keyboard on cmd+P.
The histogram is on top of all the tabs followed by the focus tool in quick-, lens- and exposure-tab.
The order of my tool tabs follow my reading of image editing - "light" first, "color" second. The lens tab on the second (fourth) position is only placed there as I do a lot of large format stuff and also because I want to check NR and sharpening (for preview only) before editing curves. Too, I apply lens corrections to my MF files as well so after rough adjustments in the quick tab I first want to adjust a "clean" image before I go ahead to "exposure" where I've cloned "base characteristics", "exposure" and "HDR" from the quick tab ... so I don't switch back to the quick tab to access these tools if needed in conjunction with curves.
So ... just an example. That's my personal concept and there are a lot of ways to create a personal workflow. But that's what is the most interessting in V5.0 from my point of view.
Hope that helps a little bit.
