@DarkerBlack I'll ask you the same question as old hardware is more likely to have a low power PSU that might not be able to support even what would be considered these days to be a modest GPU. In my case, my Win 10 machine is so ancient the highest spec graphics card I can fit is an equally ancient Nvidia GTX 1050Ti. Anything more, even a GTX 1060, and I'd need to replace the PSU, which of course is just not cost effective for such old kit. Can you give full details of your system? It will help people give you better advice.

Be sure to check the power requirements of whatever graphics card you are thinking of buying AND ensure the PSU in your machine is capable of delivering the necessary power.

The scaling recommended by Windows depends on the resolution of the monitor in use so I'm not surprised that your laptop suggests 125% but mine suggests 150%. What am (very) surprised is that @Tracy Charles said their recommended scaling for their 4K monitor is 100%. At that scale on a 4K monitor things really would be tiny. However, my surprise doesn't help solve the problem, since Tracy has already stated that they have tried changing the scaling and it hasn't helped. I've no idea why everything was OK for Tracy earlier but now it's not.

Are you sure? I'd be surprised if it is. My Win 11 laptop has 150% as the recommended scaling.

I'm no expert but if I saw that sort of problem I'd do two things: 1) Ensure the video driver is fully up to date and if that didn't help: 2) Turn off Hardware acceleration If neither of those things help I'd then wait for the experts here to answer.

Just about any current PC will run the Affinity Suite but if you want it to run well then it's a safe bet that the more you spend the better will be the your user experience. So what is your budget?

Are you sure you mean Adobe Camera Raw? I thought it was Adobe's DNG converter that enabled you to get these .dcp files. Either way, it is my understanding of these .dcp files that they are Adobe's best guess at the Canon picture styles, they are not actually the Canon original styles. I'm happy to be corrected on any / all of the above.

In Gramps, install the 'Interactive Family Tree' Addon. This will automatically output your tree and display it in the Topola Genealogy Viewer. If you like what you see, look on the viewer's 'Download' option to save a copy in PDF, PNG or SVG format. Alternatively, from the genealogy application of your choice export your tree in GEDCOM format and then manually open that file in the Topola viewer. NB although your data is displayed in your browser, none of your data leaves your device, i.e. by using the Topola viewer you are not uploading your data to the web. If you want to investigate this idea without using your own data then you can explore the examples that are on offer on the viewer's home page, here: https://pewu.github.io/topola-viewer/#/

Searching suggests this is a 'known issue' and as such there's nothing you can do. See for example this thread: https://answers.microsoft.com/en-us/windows/forum/all/canon-eos-r6-hif-images-not-usable-in-windows/339b5733-23cc-4212-abab-e03ae1e97c84

What type of layer?

Can you give us more details? Are you on Win or Mac? What version of Affinity Photo are you using? What type of file are you opening, RAW or JPEG/TIFF/etc.? How are you opening the file? Meanwhile, on my Win 11 laptop, using v2.5.3 of Affinity Photo 2, I can't reproduce your problem. The sliders in the Develop Persona change the image.

Nope, that covers it. If I let Affinity Photo (or an ancient copy of Photoshop that I have) control the printing of B&W, my prints have a magenta cast. If I let the printer driver control the process that doesn't happen.

I'm on Windows and often print photos from Affinity Photo 2 with no problems. For colour photos I set Affinity Photo 2 to control the colour management AND ensure colour management is turned off on the printer. For B&W I do the opposite. I let the printer control the colour AND ensure Affinity Photo 2 colour management is off

I suspect your budget might be a bit small, especially if you want to do photo editing as for that your really need a good quality monitor, i.e one that covers at least 100% sRGB. To get such a panel in a laptop, together with a modern GPU, investigate gaming laptops. As for an external monitor with 100% sRGB you can pay eye watering sums for such a device while a 'cheap' one might be as much as £250.

The installer for my (ink-jet) Epson printer automatically installed the ICC profiles that came with the printer. I'd expect the same thing to happen when you install your printer. Additional ICC profiles, e.g. for non-Epson papers, such as those you say will be emailed to you, will probably either : come with installation instructions for you to follow or have to be manually copied into the same folder as the other ICC profiles or have an install option if your RIGHT click on them Once they are installed they will be available within the Affinity applications.
