PowerShot SX70 HS Photos at 72 dpi

[SHLiung]

I selected the highest quality for photographing, which is, 5184 x 3888 px

Why are all the photos taken in only 72 dpi?

72 dpi is a poor quality.

Is this because my Canon PowerShot SX70 HS is defective?

My old Canon Powershot SX10 HS photos are in 180 dpi

My other old Canon Powershot SX40 HS photos are also in 180 dpi

So how can the greatly improved Canon Powershot SX70 HS photos be in only 72 dpi?

Please let me know whether my Canon Powershot SX70 HS camera's 72 dpi is a defect and if it needs repairing. I purchased it less than a week ago.

Just leave it a 72 DPI. When the publisher sizes the photo for printing, the DPI will be changed based on the size that is chosen for the book.
