You'll need to click on Mode first to select a custom ratio. 16 x 9 will do it - you don't need the extra zeros.

But how do you delete your own posts?

It's worth bearing in mind that there are times when you want a softer image - e.g. cloudy skies. You can then be selective about where you apply the sharpening,

Have look at this post from a couple of days ago.

Yes, you can select individual images from the stack - have a look at https://m.youtube.com/watch?v=YTu7M3aZ4XE

I phrased that badly - I meant it wasn't clear what Serif hoped to publish in 2018 i.e. a beta or a formal release.

I might have missed something in that post (I don't go to Specsavers) but the only statement I saw said that it wouldn't be published in 2017 and they were hoping for 2018. It wasn't clear what "published" means. Some very interesting background about development timescales though - it helps to put any predictions into context!

Has there been a statement to that effect from Serif or is that just the latest output from the rumour mill?

That's not my understanding - mine is that Affinity Publisher will be released, and the (potential) user community would like it to be this year. If you need a cheap and capable DTP programme now I'd recommend Serif's PagePlus X9 - it's likely to be some time before there's an Affinity alternative that can do better and there's a reasonable chance you'll never need anything more.

Change the font to Symbol and type "m". Affinity uses the system fonts so you may have other options.

I was thinking of this one - https://www.youtube.com/watch?v=mqrsF0imtvI&t=2s , but yours is better!

If you've opened a RAW file you'll be in the Develop Persona. The Overlay Gradient tool is on the left of the screen. Another approach is to look for the Overlays tab on the right of the screen, select it and the gradient overlay tool is the middle one of the 3 tools at the bottom of the screen. There's also a gradient tool in the Photo Persona. This is a lot more sophisticated and works on adjustment layers - there's at least one good tutorial on YouTube.

I don't understand what the problem is - you crop to the size you want and then move on. If you've got it wrong you can do a completely different crop by going back into the crop tool. How would you like AP to behave?

Affinity Publisher is an unknown quantity - PagePlus is a competent piece of software that'll set you back (I think) £19 - if you've got clients waiting it's a no brainer!

I'm assuming you're not changing the tool after doing the crop - select a different tool and then reselect the crop tool.
