Affinity Photo Export settings

[mbo]

Hi.

Sorry for the stupid question. I don't understand the export settings in the manual. I need to explain simply how to setup export. I want to have full control when exporting.

For example, I have two photos. For the first one, I need a 72dpi export. For the second one, I need a 350dpi export.

How to easily set the dpi for export?

Thanks

MB

In what format do you export "photos"? Bitmap (jpeg, png, tiff)? Then dpi has no meaning - 100 pixels is still 100 pixels.

 

The DPI of the document can be set when creating the document or when changing its size.

True, but some applications will use the DPI to determine what size to display an image (just as a printer will use it to determine what size to print the image).

P.S. to avoid completely unnecessary and fruitless discussions, here is a link to dozens of previous similar posts.

Regardless, it is used by applications to determine the display/print size of objects.

Only by some applications, & in most it is usually easy to override it, like by changing the scaling in print dialogs.

True. But if it is used that way in any applications, it is not correct to say it has no effect.

Yes, we should be using PPI not DPI, but this is a lost battle. Language usage evolves, and influences technology. It's really the same thing that happens with the arguments about dictionaries and whether they should prescribe how words should be used, or describe how they are actually used.

Hi. 

Thank you for your answers.

In another program, I have this setting when exporting to JPG/TIFF/........

That's why I asked.

And when I send photos somewhere, someone wants me to set the value to like 72 or 250 or ...

Thank you.

How many dots are in an image being displayed on a computer screen? NOT PIXELS, Dots. Printers make physical splatters of ink on a physical medium, paper, metal, glass, cloth, ect, so it needs to be instructed how many of those is required for the size to be made on the medium.

I disagree, it's only lost because people choose to belief false information. Sadly there's way to much of that going on. Not that difficult to change, just stop drinking the kool-aid, as we like to say.

Turn that around & ask how many document pixels are being displayed on the screen? Whatever the answer, it will change if the zoom level is changed, & probably also if the rendering method is changed. So then, does that mean that screen pixels change? Of course not! So PPI can unambiguously refer only to the screen itself, but not to the pixels of the document, unless you accept that it is variable, both in how it is displayed on screen & how it is printed -- which may or may not be scaled during printing & may or may not deposit ink droplets ("dots") on the print medium, depending on the printer technology.

Basically, I think any "per inch" or similar per linear measure (whether dots or pixels) terminology should be applied only to physical objects like printouts or screens.
