Idea: Within Lightroom, Brushes with simple effects built in, such as a strong blur, pixellation, or solid color. It would be similar to how adjustment brushes work.
This would allow users to use LR to markup images quickly (such as circling an important object, adding a signature, etc) as well as make it easier to blur out details such as faces or body parts. Having these tools in LR would improve the workflow because users wouldn't need to also open each image individually in Photoshop.
Right now, if one needed to blur out something like a face or other body part, the only options within Lightroom are to use an adjustment brush to lower texture and sharpening, and apply the effect multiple times over with diminishing results.
The only practical solution to blur or pixellate an object is to open the image into adobe photoshop, do the effect there, and save a copy. This slows the workflow by requiring more steps, and loses the ability to non-destructively edit photographs.
For example, if one were to do the blur effect after making exposure adjustments and making a copy, undoing those exposure adjustments would require making another copy from the original image. Likewise, making separate versions of images, such as color and black & white, would require opening up each image and its duplicate in Photoshop, whereas this task could be accomplished quickly in LR by utilizing virtual copies feature.
All this also applies to marking up images. For example, if I had an image of a strangely dressed man in a large crowd, and I wanted to draw an opaque yellow circle around him, I'd need to open the image in photoshop.
Thank you for reading, I think this would make it easier for many creators to mark up images, maintain privacy, and abide by content guidelines.
