Fritz, thank you, I understand now, I previously thought (due to not reading properly) that you were talking about Affinity rather than IrfanView. Sorry, and thanks again for your help You will be pleased to know that I have long been a fully paid up and licensed IrfanView user. I also found this tutorial on YouTube which seems to be the sort of technique I need to improve my low res image:

Thanks everyone for your input. I can see how this seems, newbie doesn't understand jpeg compression. Actually I have been working with jpegs for over 20 years so I know them quite well - it is Affinity that I am new to. The problem I am seeing is only revealed if you look at the same image in Affinity and another viewer side by side. The screengrab below shows the image in Affinity on the left, overlaid on the right with it in Irfanview. The Affinity view is noticeably more blocky and pixellated, and has more artifacts around the letters, than the Irfanview view, which renders the letters much smoother. Look closely at the "acier, cuvettes acier" wording, in Affinity it is noticeably less clear and harder to read, and this effect gets much worse as you zoom in. When I first opened this image in Affinity and zoomed in to the detail shown in the crop in my first post in this thread I was shocked by how badly it was pixellated. I didn't want to start working on cleaning it up in Affinity, because it looked like just loading it into Affinity had lost a lot of detail that existed in the original. That is why I started this thread. Why does Affinity seem to be chucking away details in my original image? I am sure it is not meant to do that, so I must be doing something wrong when I am loading the image. Or is it that Affinity is giving me a more true view of what is actually in the file, whereas Irfanview is trying to make it look as good as possible and smoothing away artifacts? Post script: Opening the original image in Inkscape also doesn't show the same blocky pixels as the Affinity crop shown my first post in this thread.

I have a poor quality jpeg of a catalogue from 1898 and no time machine. I thought I would get a page into Affinity and smarten it up a bit. But when I open it in Affinity it becomes badly pixellated. This is as far as I have gone, just opening it in Affinity. The Affinity view is pretty well unreadable compared to the original, this doesn't seem to be just the effect of zooming in. This doesn't look right to me, what's going on? And any suggestions on how to improve the original would be gratefully received 🙂

Hi, thanks, and thanks for your quick reply. I have tried to do as you suggest but I am finding it difficult to get the selection to follow the edge of the dial smoothly, see the selection line in the image, is there an easy way to smooth the selection curve? I did originally try to select the dial area using the elliptical marquee tool. If I did this in Gimp I would make a rough selection and then zoom in top, bottom, left and right and tweak the selection to be more accurate, but I couldn't find a way to drag the size / shape of an elliptical marquee with the mouse; is it possible?

I am new to Affinity and this is my first question, I apologise that it is so simple. I have created this image and removed the background, in a jpeg it is rendered white. I would like to make the watch dial whiter but without changing the colour of the strap, so I don't want to change the colour balance of the whole image. Ideally I want to only change the white of the dial. Thanks for any instructions or helpful suggestions!
