How to visualize dust spots on scanned neg in PS without using ACR or LR

[Molli]

I don't see any selection box for visualize dust. I'm using the purchased version not the CC version.

Hi Alan,
Hopefully my set up looks similar to yours. I've circled the healing brush [top right], and placed a rectangle around the "Visualise Spots" option at the bottom of the image, around centre stage. I hope this helps:

Molli Yes I found it. Thanks.

I found that isolating a color channel and changing brightness/contrast etc you can make the dots pop out. Do your dust deleting, then turn on all color channels and make a final pass. Be sure to use an adjustment layer for whacky brightness and contrast adjustment to make the dust stand out so you can delete it when done. I also use a blank layer just above my base image layer and do all of my healing, spot healing and cloning on this layer. Only the patch tool will not work, but unless I am doing something drastic, like removing a park bench or annoying sign, I don't use the patch tool.
