S-Hi Emulation - second try ...

Having made a fool of myself in a previous post , I though I would try again - this time with a SD15 shot of the same scene through an old 24mm M42 SMC Takumar lens. Recall that S-Hi (Quattro) doubles the MP, not the width. I think I got it right this time.

Full size 2640x1760px:

"S-Hi" 3736x2491px:

Best viewed original size, tabbing back and forth to compare.

It seems to me that the Quattro S-Hi mode is little different to up-sampling for printing or viewing on a 4K or 8K screen, but I don't have a Quattro to compare like with like.

Some might say it's more trouble with a non-Quattro file but RawTherapee can save and re-use all adjustments as a camera input profile and you're going to edit most images anyhow ...

Personally, I have no use for up-sampled images because I don't print and I'm quite happy with my current monitor resolution, having no intention to "upgrade".

Nevertheless, it was an interesting exercise.

Comments welcome.
