St Thomas’s, Old and New

This is St Thomas a Becket church at Heptonstall, near Hebden Bridge in West Yorkshire.

The photo was taken as a three-RAW-file HDR bracket set at 2:30pm on the 10th of August 2021 and developed with On1 Photo RAW – my favourite photo software! (See my previous post, Robin Hood’s Bay for details of my summer software struggles in 2021.)

Typical of my approach, I went for a low and wide-angle composition featuring the walls of the derelict St Thomas a Becket ruin with plenty of perspective and vertical convergence.

The ruin’s newer replacement, St Thomas the Apostle, is featured as the distant view through the central archway.

As with a lot of my photography, I’ve shot this subject in a similar way before. Although previously, I hadn’t had the benefit of the 10-18mm (APS-C) ultra-wide-angle lens. Here, it was 10mm – as with most of my architecture and landscape shots.

There is another interesting view of the church, and I pay post that soon.

Recent Changes and Display Issues

With this and my previous Robin Hood’s Bay photo, I had noticed that the displays weren’t of the expected image quality, and I wasn’t sure why.

After some thinking and experimentation, I discovered the following:

The images appeared to be over-sharpened. This turned out to be a result of new features in On1 Photo RAW’s 2022 version.

We now have No Noise AI to sort the sharpening and noise reduction for us, which I am really happy about, because I’ve always found sharpening and noise reduction a bit of a chore. We also have a new export dialogue.

In short, I’ve found that any output sharpening can be too much for the web.

And after some research, I learnt about this:

Visible diagonal jaggies. I have my recently-purchased MacBook Pro, with its high resolution Liquid Retina XDR display, and ironically, I had begun to notice visible diagonal jaggies.

Apparently, browsers upscale images when they detect a high-resolution device to meet the expected display size. But if you publish the image at twice the usual display size or more, the browser takes advantage of the higher resolution and the aliasing problem is gone.

As a result of the above, I now publish much larger images and without any output sharpening.

I’m not totally sure of all this, however, because my previously published photos here seem to look fine and don’t have any sharpening or aliasing artefacts. Time will tell.
