JPEG Export changes Resolution (dpi)


Recommended Posts

Hi Serif,

I currently run into a problem of false Resolution after following workflow:

- open Scan 600dpi (.tif)

- resize to 300dpi (¼ pixels, same print size)

- save as Affinity Photo file

- Export as JPEG

As a result closing/opening the files I saved, the .afphoto has the correct 300dpi, but the .jpg has again 600dpi at the same pixel count (so it will be printed half as long on either side). I think that's a bug, isn't it? I'm using Photo 1.5.1 on a Mac with 10.10.5.

 

I'd like to know if you can reproduce and address this.

Thanks for your answer!

PS: Of course, I still appreciate any feedback on my topics (1, 2) concerning batch processing, too.

One reason this can happen is if you have "Embed metadata" enabled (in the "More" section of the export dialog) & the original file had a dpi values embedded in it. In that case, the original embedded dpi values are preserved.

Thanks for your fast response! OK, so it embeds obsolete dpi values as metadata which will be read as the actual dpi afterwards? Is there any benefit to this?

Anyways thank you for the workaround, saving it without metadata will in fact save the correct resolution as a fast test showed.

It is up to you to decide if the original dpi values should be retained. Note that for web pages & just about anything else besides printing, the dpi values are irrelevant, & relevant for printing only if the printing software & print driver uses them.
