Very useful!

I see I'm not the only one who uses the Hue slider aggressively I find it much easier than a channel swap, as well as allowing a wide variety of results without any effort.

Agree. I spent hours processing files in DxO PL5 and then loading results in Adobe Lightroom to do the somewhat complicated red/blue channel swap, then bringing them back into PL5 for final processing, before learning you could do it in seconds with the HSL hue wheel directly in PL5!

Having the photos in series makes it very difficult to compare results. Having them presented as low resolution 4x4 composites would make that much easier to look at the most relevant shots - but might involve quite a bit more work...

Agree, there's no easy way to present a lot of images for comparison in a chat format. I placed the images in order sequenced by the similarity of the filter and roughly from short wavelength to long wavelength, to try to make some sort of comparison possible.

If you're using a desktop (not mobile) browser, you can click an image to view it full-screen, then use the arrow keys to quickly toggle through the images.

Here's a 9 x 5 image of thumbnails you can view magnified, or download, with all the images in order. For reference, the image info is below. Good cases for comparison are bolded.

If you want to compare particular images, I suggest downloading them from the magnified view and then you can view them side by side on your machine.
