I posted but one video with the new UI: https://www.youtube.com/watch?v=RQBFGzoPReE


I also couldn't recover when I purchased version 2 and thus know what the update costs me. That was on June 24th 2014 and thus a decade before the grace period of free upgrades to CP3 Base. Hence the regular ...

These were just taken during a family trip to the Danish North Sea coast. Since I was invited along and did not want to turn the holiday into a full-scale photographic expedition—or drive everybody mad with bags of cameras—I limited myself to an iPhone and a pocket-sized Sony RX100.

The images ...

Mail me the key in question and I'll look at it

Small update regarding private messages:

Registered users can now contact me and any future administrators by PM, and I / administrators can reply. General member-to-member private messaging remains disabled.

That distinction is deliberate and was again complex to build. Hosting private ...

Interesting—I had never noticed those page-load animations, as they do not appear in my preferred browser version. Since I do not like them either, I extended the same custom extension I had already written and removed them altogether.

The subtle unread-icon pulse remains for users who have not ...

Yes and they will likely stay that way
My email address is known plus we have the contact form also https://www.colorperfect.com/ColorPerfect-Contact-Form/

I have also added a customized gray prosilver variant, without the unbearable blue palette, for members of the Registered CP users group.

I do not personally consider prosilver superior—it feels rather dated to me—but I am not going to tell actual ColorPerfect users what they should prefer. Where ...

Yes, the Lounge is fine.

Depending on when you bought CP2, you may qualify for a free upgrade to CP3 Base.

For Meta, however, the best option is still Student Meta for 2 at €129, as it is cheaper than any upgrade path.

If you do not have another student to share it with, just buy it yourself and ...

Thanks for pointing this out.

The only animated element I could find is the subtle pulse on unread forum and topic icons. I found the request to respect prefers-reduced-motion reasonable, so I wrote a small custom phpBB extension that disables this pulse for users who have reduced motion enabled ...

The Zoom levels available to you depend on three things:

Image size in pixels
Dialog size on screen
Pixel density of said screen (Retina or not for macOS)

So, try making your plug-in window be the smallest possible and get a different list.
Or for testing resample your image to double its ...

In case there is a problem I must fix it, I would not be aware of one but you can send the Tiff by Wetransfer or similar and I'll see it gets in here

It might also make sense to disable the feature when using the "make selection and open CP while holding down the Shift key" method you suggested earlier in the thread.
It always has been that way. That is the whole point of that feature :D The selection gets heeded no matter what.

I have sent a new build to everyone active on this. It tackles the false-positive cases presented here while still working reasonably well on actual negatives. Furthermore, it no longer has any impact on modes outside of ColorNeg.

From here, I think there are two possible paths. If it holds up well ...

A short summary of the longer thread I linked above:

Yes, this can be expected. PerfectRAW is not trying to hide the raw sensor noise from you. In a dark, smooth blue gradient, chroma noise may therefore become more visible than it ...

In more general terms, I'm just trying to find images that tricks the algorithm so Christoph can use them to improve it. I imagine building a foolproof algorithm that always knows what's part of the image content and what isn't is a pretty hard problem. There are probably a lot of edge cases ...

Then some Fuji Xtra 400 frames.

Wonderful, thank you. I already have a bunch of qualifiers to assess if a geometry is a frame or may be a window in the photo for example only I lacked a feeling for what values to use as thresholds. I suppose I'll fine tune this some more tomorrow, make a binary ...

Nice, maybe something can be learned from them.

An update on this.

I have spent considerably more time on the frame-detection question over the last couple of days than I originally intended. The extended test set has made one thing fairly clear: the comparatively simple sensitometric, or density-/brightness-based, approach I had hoped might be ...

First:
Thank you for posting this example,
It is precisely the example that is helping me see where I need to do better still in terms of detecting a potentially harmful outside.
I won't go into it, I'll just try to fix it.

Second:
You do not need to crop anything:

One simply needs to know ...

Being able to work with the edge of the negative without it affecting the curve calculation is a useful option for many.


I should add that we have always had this ability in CP3; one simply needs to know what to do. If you draw a rough selection over the negative area, making sure not to ...

I found that the underlying reason for the observed difference I mentioned was in the fairly new frame detection.

Perhaps it was not the best idea to introduce that so late in the process, but the idea had enough merit, since for some reason it seems unintuitive to new users to crop to the negative ...

Addendum: I think this is a bug after all.

When I started working on the above, I assigned sRGB, called CP, and it came up in PerfectRAW because of my previous use on Roberto's cliff image with the two gulls and my rose example. I switched to ColorNeg and did what I did without any bumps in the ...

I'm back from my short trip and have looked at this briefly.
For now, I'll just post what I saved while doing so.
Film_054_Bild_024.jpg
I did make screenshots to revisit later. This is the sRGB thought. If the gut feeling that wide profiles are involved in what you saw holds up, I will need to ...

Roberto, howdy,

thank you for this illustrative image post. I enjoyed looking at its hidden details.
I think I can explain what is happening here, and in this particular image the explanation is actually rather simple.

The darkest meaningful parts of the scene are probably the black feathers of ...
