From Youtube: Drum Scan vs DSLR vs Epson (Via Nick Carver)

Lachlan Young said:

The negative was an ok choice for comparing colour rendering/ gamut behaviour, it wasn't a good choice for sharpness/ noise comparison.

You seem terribly reluctant to show us an HP5+ scan at the resolutions I suggested, with and without your claimed sharpening. Is it because you know what the results really are?

Lachlan, if I post my scans you will say that images are forged, so let's use reference material that is trustworthy:

My proposition is starting with those samples from the Pali K test: https://www.largeformatphotography....rum-Scanners&p=1479178&viewfull=1#post1479178

Just inspecting the original scans and technically debating the differences, I ask you and me both make a neutral approach to see what that side by side demonstrates or not, as scans made by Pali are absolutely trustworthy reference material. Do you acept the challenge ?

Well the video mentioned in OP may have technical shortcomings, but I’ll give it one thing: it’s a lot more entertaining than this thread.

My word this is dull, and I came in here thinking that I may have learned something.

No, I've shown way upthread what your sharpening does to the Epson files compared to the drum scanners. I've also provided a range of results showing the resolution of a Hasselblad X5 at three different resolutions without sharpening. The onus is now on you to provide new material evidence of the abilities of your own Epson scanner. It'll take you less time than writing another lengthy response dodging the substantive questions that you are desperately avoiding answering. If you can't or won't, the inference is clear that you have nothing whatsoever to add to this thread other than innuendo and nonsense.

Ok, if you don't accept the challenge to analyze trustworthy reference material then I've nothing else to debate with you. This says you don't want to get trustworthy conclusions but a dirty debate on my images, so no debate with you is worth.

This is my final position: https://www.photrio.com/forum/threa...on-via-nick-carver.172770/page-9#post-2255477 anyone can judge those evidences, if they are meaningful or not.

In particular that test made by Pali K (https://www.largeformatphotography....rum-Scanners&p=1479176&viewfull=1#post1479176) is totally trustworthy, neutral and self explanatory, I recommend anyone wanting to know the truth just taking a look.

Pali K concludes in that post (botton, under image):
"What is most interesting is that in real life, DPI resolving power may not be adding a whole lot if the image itself doesn't have the resolution to begin with. It will be nice to see how slides look side by side and I expect to see bigger differences there."

In the next post I made an slight sharpening, for a total match:

Disclaimer: at all I'm saying that a Pro scanner does not make sense, it does, just my view is that at home we may obtain totally Pro results with the Prosumer Epson gear, making some careful edition which anyway is always necessary.

That's all.
