I installed high Sierra a few months ago and nowadays there seems to be a problem with System Information.app, it always shows the disk usage wrong like for example System 40GB but it shows photos to be 0KB even though I have 19GB worth photos and DaisyDisk reports correct disk usage. 

I have tried booting into safe mode and rebooting, this persists after restarts

I have run this scan as root user not admin.

so how do fix this missing photo sizing in system information.app?

Answer: 
You need to reindex your Spotlight cache. To do this

1. Go to System Preferences → Spotlight → Privacy
2. Click on the plus symbol and add your macOS hard drive you're having the wrong status/info problem
3. After adding your particular hard drive, quit System Preferences then wait for a few seconds.
4. Again open System Preferences → Spotlight → Privacy and this time remove your previously added hard drive.

What this does is it reindexes and creates the .Spotlight-V100 files on your hard drive. There are also various sudo commands to perform this step but for now try this!
I solved this issue just relaunch finder.
Click on apple logo->Force Quit->Finder and click Relaunch. 
So I opened my finder and it shows the correct size.
