Following on from the previous post I thought I would just share why I don’t use the Legacy Healing Tool. The Legacy Healing Tool uses the Photoshop CC 2014 and earlier Healing Brush algorithm. The current version sample is now real time and uses a different algorithm. Some still prefer the Legacy settings and that is why the option to select Legacy Healing tool is found in the top bar in Photoshop when the Healing Tool is selected.
The healing tool is used to correct imperfections in an image. Photoshop takes the sample you have taken and matches the texture and luminosity from that source point and pastes onto the destination, the area you want to edit. To create that sample you need to Option/Alt -Click.
So I did a little test and I’m clearly not old school.
