Hello All,

 

Could anyone point me to more details of how the below fields are calculated for any asset uploaded to AEM DAM? Which workflow step is responsible for it?

I believe this is a setting that is made with Photoshop within the picture.
Open up a picture in Photoshop, then select image > image size 
on the bottom you see the value in the resolution that was assigned to the picture.

I just had a quick test - opened up a picture, set the resolution to 123ppi and uploaded it into DEV.
As expected - the file now looks like this:

Why does this value bother you? 
Does it have an impact on something? 
Pixel size matters for most use cases - not dpi/ppi

Thanks @Adilos-Cantuerk for the update.

We get value as "-1" for both dam:Physicalheightindpi and 

dam:Physicalwidthindpi for most of the (90%) assets and thus wanted to check what logic is responsible for this.
