A place to politely discuss the tools, technique and culture of photography.
This is not a good place to simply share cool photos/videos or promote your own work and projects, but rather a place to discuss photography as an art and post things that would be of interest to other photographers.

As usual most people here have no idea what DPI is.
DPI is a translator between digital space and physical space
If you have a picture of 500x500 pixels … how big is the picture in real life ? You don’t know. It can be 500 meters tall if you make 1 pixel 1 meter.
DPI (dots per inch) you can also say PPI (pixel per inch) is a value that you set if you want the highest quality print of your image if you don’t have a physical size limit. Example printing your stuff for an art show.
Now back to the initial image.
If you have a 500x500 pixel image and you set the DPI to 100 , now you have a 5x5 inch image printed.
If you have a fixed size you’re gonna print for example A4 , you don’t need to set the DPI.
What you did is basically tell the printer that you want your image to be printed much bigger than the actual space it was going to be printed, therefore it resulted in cropping .
Nope!
You started out fine, but like so many other people, you're equating DPI and PPI, and calling them the same thing. DPI is purely physical, for printing, and PPI is purely digital, for viewing. There is ZERO overlap between the two.
There isn’t zero overlap , a pixel will be converted to a dot.
Making that statement makes it easier for people to grasp the concept, and does zero damage.
Exactly right ...
