DPI problem in Sony Xperia Z5 Premium Camera and deactivate automatic ISO in 23 MP when is MANUAL

[Telperion]

I need to take pictures at least in 300 dpi, but Sony Xperia Z5 Premium take them in 72, how can I change to 300 dpi before I take pictures? I bought this phone just because the features of the camera. I also want to know, how I can deactivate the automatic ISO in manual when I want to use 23 MP, and even if it is not manual. I can change it only in 8 MP, but obviously, is not what I want and what I need.

Thank you.

The dpi value is just a number in the EXIF data - it has no meaning unless you state a physical picture size in inches or centimeter.

You can easily change this value in any picture you already have with freeware tools, e.g. Exif Pilot (http://www.colorpilot.com/exif.html).

The second part of your question I can't answer, because I am using a Xperia Z3 Compact - the one this section refers to - and with the Z3 Compact it is possible to change ISO to manual even in the highest resolution in manual mode.

You better raise this question in the Z5 section.

Thank you for answering, but that program doesn't solve my answer. I thought I was posted my question in the Z5 section. Should I ask again there?
