When using spot removing tool my images are portrayed as negatives???

Un Check the tick box in bottom left under your image that turns this negative view on and off. It is helpful to find spots but you can switch it off. P

Hi Chrissy! Check if you have Visualize Spots ticked in the bar just below the image (and above the filmstrip) when the Spot Removal tool is selected. If ticked, then untick it.

Also, the equivalent key to the Ctrl (or Control) in Windows is the Cmd (or Command) key in macOS - not the control key (which Macs have, but that's for another purpose). So you need to press Cmd-H to minimise/hide the active application window on Macs...

type A to hide it.

One note: you can't Hide in full screen view, hit the green button to leave Full Screen View, then Hide becomes available.

Sorry all I thought my email4 reply worked! Thanks for solving this the A command worked, and found visualise spots I now realise is when delete button has been pressed! Also my mistake I meant to say command H not control. And car,is I can’t see geeen button in my Lightroom! Learning curve but thanks for help!
