OR

Print at a smaller size

Or

Print at a lower DPI (eg 200).

What is the cropped pixel dimension of that image?

1097x1646 @ 72dpi

Wrt printingā€¦does this helpā€¦

Thanks Todd, Iā€™ll check it out when I can find a few spare minutes. Much apreciated!

1097x1646 original pixels before upscaling (dpi is not relevant here) will give you a good print of ~4x6 inch in general. This can be viewed from a very close distance. A dimension of ~7x11 inch might still be acceptable. Larger prints loose quality and should only be watched from further away. Exact dimensions depend on the image.

ā€œNormalā€ upscaling like in darktable export will not help you here. However, there are some upscaling algorithms and even AI that could improve the image while upscaling. You would have to test these. But I would not hope for a good quality image more than 2 times the original dimension mentioned above.

Thank you Thomas.

So in other words, Iā€™m pretty much wasting my time and money if Iā€™m looking to print an upscaled A3 using a severely cropped image, even though it may look ok on a 65" TV from a short distance?

I guess the more mm the lens has = the less crop required = the better the resolution for printing. Time to save some pennies then.

Much appreciated.

You could check the quality with a test print to save money. For example, instead of printing your whole 1097x1646 pixel image on 30x45 cm, you could crop the central part of 366x549 pixels and print it on 10x15 cm.
