The Return of Topaz Adjust AI

Since updating my Mac to the Big Sur OS, I haven’t been able to use Topaz Adjust AI. This week I discovered there is a new release of Topaz Adjust that works on the Mac Big Sur OS. Although it’s not an application I use a lot, it’s very useful for making quick improvements to images. It also includes the old (now retired) Topaz Detail adjustments to enhance image details.

The reason that I discovered the new release is that I was processing a film scan of the image below.

Bamburgh Castle, Northumberland

I shot the image many years ago on a Pentax 67 MkII medium format camera with a 55mm lens. I was using Fuji Velvia 50 slide film. I don’t know the original camera settings but I do know it was before sunrise so it must have been a long exposure. That may account for the purple/blue shift in the image colour as the old Velvia 50 has a habit of doing this with long exposures. The image you see is a reasonably accurate match for the physical slide.

The image scan was only made recently using my old Epson Perfection V700 scanner. The scanner has made quite a good job of extracting the detail in the dark areas of the slide but suffers from being soft. This is a common problem when scanning with a flatbed scanner and the image quality doesn’t appear to match a digital camera.

But I’ve found an easy solution to this problem that doesn’t involve buying a new scanner or even paying someone else to scan my film. If I apply Topaz Sharpen AI to the image the fine detail pops out to produce an excellent quality image. If you want to see the processing I use watch this week’s YouTube video (

And in case you don’t like the purple tones in the film scan here is a colour corrected version.

I hope you like the images and video and have a great weekend. I’m off to rebuild a dry stone wall at one of the local farms.

    1. It’s consistent with the film version; slide film is extremely sharp. If you’ve even projected a medium format slide you will know what I’m talking about. The scanner is most definitely the problem and it softens the image quite a lot.
