Example of not that well organized layer structure. After finishing retouched image you don't always have time or energy to start reorganizing and renaming the layers. Putting them into groups, adding explanations or color codes describing what the layers are in image and deleting unneeded layers. Deleting duplicated base layers/merged layers and textures that are not used in final image can save lots of hard drive space. Keeping files tidy and compact will also make them faster to open & save. Saving time & hard drive space is saving money.
Yours truly, teaching portrait retouching basics about month ago. Non destructive image editing with layers was new to some listeners and I heard they updated image editing workflow after my presentation. When I teach Photoshop basics, I mention the layers, masks and blending modes to be the most fundamental tools with the software.
